All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The network request method provided by the present application can be applied to the application scenario as shown in fig. 1, wherein the terminal device 110 can be but is not limited to various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices. The server side 120 may be implemented by an independent server or a server cluster composed of a plurality of servers. The terminal device 110 and the server side 120 are connected via a network. If the terminal device 110 monitors the trigger event, traversing the IP address corresponding to the candidate domain name in the pre-stored IP configuration data, and establishing a test connection through the IP address; acquiring round-trip time of each traversed IP address for establishing test connection each time to detect whether each IP address successfully establishes the test connection each time and acquire connection state information; updating the connection data corresponding to the IP address according to the connection state information of each connection establishment test of the IP address; intercepting an original network request sent to a target server, and extracting a target domain name from the original network request; if the target domain name is any candidate domain name, acquiring an IP address corresponding to the target domain name as a candidate IP address, calculating the total weight of each candidate IP address according to a preset rule, IP configuration data corresponding to the target domain name and connection data of the candidate IP address, and taking the candidate IP address with the highest total weight as the target IP address; based on the request protocol of the original network request, updating the original network request according to the target IP address to obtain an updated network request; an updated network request is sent to the server side 120.

The target server and the designated server in the present application are both one of the servers in the server side 120. The designated server is used for storing and managing the IP configuration data of the server corresponding to each candidate domain name. The servers and the terminal device 110 can be connected through a network. Terminal device 110 may request a designated server to obtain IP configuration data corresponding to each candidate domain name, and may also initiate a network request to a server corresponding to each domain name.

The local end of the present application is the local end where the terminal device 110 is located, and the local end includes a local disk and/or a local memory of the terminal device 110.

Fig. 2 is a flowchart illustrating a network request method according to an embodiment of the present application. Referring to fig. 2, the method is illustrated as applied to the terminal device in fig. 1. The network request method includes the following steps S100-S700.

S100: and if the trigger event is monitored, traversing the IP address corresponding to the candidate domain name in the pre-stored IP configuration data, and establishing test connection through the IP address.

Specifically, each candidate domain name corresponds to one piece of IP configuration data, and the IP configuration data is stored locally in the terminal device. The candidate domain names are domain names corresponding to all websites (sites) that the user can access through a specific application program or APP installed in the terminal device. For example, the number of the candidate domain names corresponding to one website may also be any number, such as 1, 2, 3, and the like. One candidate domain name corresponds to at least one IP address.

The triggering events include: over a time interval, or a change in network status occurs.

The network state change comprises the following steps: network disconnection, network switching, for example, switching the network from a 4G or 5G network to a wifi network.

A test connection is established over the IP addresses for testing the availability of each IP address. Due to the complexity of the network environment, the availability of IP addresses has uncertainty, and it is possible that at the last time a certain IP address is available and at the next time the IP address is not available. By repeatedly monitoring and recording the availability of each IP address, the optimal target IP address can be screened out in the domain name resolution process.

More specifically, for example, a timer is set in the terminal device, the timer is triggered once every time a time interval (e.g., 1 minute) elapses to generate a trigger event, and all IP addresses are re-traversed and tested once per the above step S100. Meanwhile, the network state change of the terminal equipment system is monitored, and every time the network state changes, the availability of all the IP addresses is traversed again and tested once according to the step S100.

The test connection may specifically be a socket connection.

S200: and acquiring the round trip time of each traversed IP address for establishing the test connection each time so as to detect whether each IP address successfully establishes the test connection each time and acquire the connection state information.

Specifically, since there are a plurality of total IP addresses, it is necessary to establish test connections by IP addresses one by one. When the establishment of a test connection of a current IP address is completed, the round-trip time for establishing the test connection of the current IP address needs to be acquired, and whether the establishment of the test connection of the current IP address is successful or not is established according to the round-trip time. Thus, the current availability of all IP addresses can be traversed and tested in a complete testing process.

The working principle of step S200 is described below with a specific example:

the time for starting to establish the connection is taken as the starting time, the response data received by the server is taken as the ending time, and the difference value between the starting time and the ending time is taken as the round-trip time. Judging whether the test connection is successfully established or not according to the round-trip time, if the round-trip time exceeds a first time threshold (for example, 5 minutes) or the round-trip time is a second time threshold (for example, 0 minute), indicating that the socket interface is overtime or unavailable, judging that the test connection establishment of the IP address fails, recording the number of times of the test connection establishment failure of the IP address once in terminal equipment (for example, in a memory and/or a disk cache), and simultaneously recording the time point of the failure; if the round trip time is not the second time threshold and does not exceed the first time threshold (for example, 5 minutes), it indicates that the test connection is successfully established, and records the number of times that the connection establishment of the IP address is successful once in the terminal device (for example, in a memory and/or a disk cache), and simultaneously records the time point when the connection establishment is successful. Regardless of whether the connection is successfully established, the round trip time synchronization is maintained, and the record with the time as the second time threshold (e.g., 0 minutes) is rewritten to the first time threshold (e.g., 5 minutes) for subsequent calculations. The server of this embodiment may be a target server or other servers.

S300: and updating the connection data corresponding to the IP address according to the connection state information of the test connection established each time by the IP address.

Specifically, the connection state information is some connection information of the test connection, and includes, for example, whether the connection is successful or not, a time point of the successful connection or a time point of the connection failure, a start time, an expiration time, and the like of the connection. The connection data of an IP address is a statistic of relevant information for all test connections of that IP address.

S400: intercepting an original network request sent to a target server, and extracting a target domain name from the original network request.

Specifically, the original network request is generated by the terminal device according to a user instruction acting on a specific application program or APP or a webpage, the target server is a server that the user wants to access, when the terminal device initiates any network request to the target server, the terminal device firstly intercepts the request, and the original network request carries a target domain name.

S500: if the target domain name is any candidate domain name, acquiring an IP address corresponding to the target domain name as a candidate IP address, calculating the total weight of each candidate IP address according to a preset rule, IP configuration data corresponding to the target domain name and connection data of the candidate IP address, and taking the candidate IP address with the highest total weight as the target IP address.

Specifically, the terminal device obtains a target domain name in the original network request, and determines whether the target domain name can be directly converted into an IP address for transmission by determining whether the target domain name is a candidate target. If the target domain name is the candidate domain name, the target domain name can be directly converted into the IP address, and then the next searching processing is carried out. The next searching process specifically comprises the following steps: and searching whether target IP configuration data corresponding to the target domain name exists in IP configuration data prestored in the terminal equipment. The target IP configuration data includes at least one candidate IP address, and therefore, when the number of the candidate IP addresses is greater than or equal to 2, one target IP address needs to be determined according to the weight of each candidate IP address. The weight of the IP address is related to the IP configuration data, the connection data of the IP address. The weight of the IP address can be determined from multiple dimensions according to the IP configuration data and the connection data of the IP address, and the obtained total weight has more reference significance. The highest total weight indicates that the target IP address is the currently optimal IP address in the candidate IP addresses. The target domain name may be resolved to the target IP address.

S600: and updating the original network request according to the target IP address based on the request protocol of the original network request to obtain an updated network request.

Specifically, different request protocols have different processing modes for the original network request after domain name resolution.

In a specific embodiment, step S600 specifically includes: and if the request protocol is an http protocol, performing first processing on the network request according to the target IP address to obtain a first network request, and taking the first network request as an updated network request. And if the request protocol is an https protocol, performing second processing on the network request according to the target IP address to obtain a second network request, and taking the second network request as an updated network request.

S700: an updated network request is sent to the target server.

Specifically, the terminal device may request data from the target server according to the updated network request.

The IP configuration data corresponding to each candidate domain name is locally stored in the terminal equipment, when a network request sent to a target server is obtained, the network request is intercepted first, a corresponding optimal IP address is searched locally in the terminal equipment, and the original network request is rewritten according to the optimal IP address to obtain a new network request for accessing the target server. According to the method and the device, the domain name does not need to be analyzed by the operator any more, so that the analysis of the operator can be bypassed, and the hijacking risk and data pollution brought by the analysis of the domain name by the operator are avoided. According to the method and the device, the domain name is locally resolved, the step of applying for resolving the domain name to an authoritative server is reduced, the domain name resolving speed is optimized, the weight is calculated from a plurality of candidate IP addresses corresponding to the target domain name according to the connection data of each candidate IP address, and the optimal IP address is selected, and the optimal IP address is the IP address with the optimal connection state, so that the network request speed can be greatly optimized. According to the method and the device, the network request is processed differently to generate a new network request according to the request protocol, the network request is processed adaptively under different scenes, and the application range of the method and the device is expanded.

In one embodiment, before step S100, the method further comprises the steps of:

requesting to obtain IP configuration data corresponding to the candidate domain name from a specified server;

and storing and/or updating the IP configuration data returned by the specified server to the local end.

Specifically, the designated server is an operating server or an application server (for example, a website server including a web server or an app operating server) corresponding to a specific application program in the terminal device, or the designated server is a preset trusted server in which a correspondence relationship between a domain name and an internet protocol IP address and other related information are stored.

The designated server stores domain names corresponding to all websites that can be accessed by a specific application in the terminal device 110, and IP configuration data corresponding to each domain name. Wherein, each domain name can correspond to 1, 2, etc. different IP addresses.

After a specific application program in the terminal equipment is started each time, the IP configuration data corresponding to the candidate domain name is requested from a specified server, and each domain name corresponds to one piece of IP configuration data. The IP configuration data at least includes all IP addresses corresponding to the domain name.

In another specific embodiment, the IP configuration data may include at least one of the following in addition to (1) all IP addresses corresponding to the domain name:

(2) service operator information

(3) Expiry time or validity period for each IP address

(4) IP priority of all IP addresses in the domain name

The local end comprises a local disk and/or a local memory of the terminal equipment.

The appointed server returns the IP configuration data to the terminal equipment according to the request of the terminal equipment, and the terminal equipment detects whether a local disk of the terminal equipment has cache records corresponding to an operator and a domain name: if not, directly caching the IP configuration data in a disk; if so, the old stored record is overwritten or updated according to the IP configuration data.

In one embodiment, the method further comprises: caching the acquired IP configuration data in a memory in a mode that the domain name is key and the IP configuration data is value. Therefore, the search can be accelerated, and the search time is saved. For example: key, value is domain name: IP configuration data.

Of course, the IP configuration data in the disk may also be stored in a form that the domain name is key and the IP configuration data is value.

The searching whether the target IP configuration data corresponding to the target domain name exists in the IP configuration data prestored in the terminal device specifically includes: firstly, searching target IP configuration data corresponding to a target domain name in a local memory cache of the terminal equipment, and if the target IP configuration data corresponding to the target domain name does not exist in the local memory cache of the terminal equipment, searching the target IP configuration data corresponding to the target domain name in a local disk of the terminal equipment.

In one embodiment, after step S400, the method further comprises: and if any candidate domain name cannot be found to be matched with the target domain name, or the target domain name is any candidate domain name but any corresponding candidate IP address cannot be found, sending an original network request to the target server.

Specifically, if the target domain name is not a candidate domain name, the target domain name cannot be directly converted into an IP address, and the original network request is directly sent to the target server. Or, if the target domain name is a candidate domain name, but there is no corresponding IP address in the IP configuration data of the candidate domain name (i.e. the IP address is null) or there is no candidate IP address or there is no target IP address matched with the candidate IP address, the target domain name cannot be converted into any IP address at this time, and at this time, the original network request is also directly sent to the target server. At this time, the domain name resolution in the original network request is not the local resolution of the terminal device, but the domain name resolution is resolved by an authoritative domain name resolution server in the network, which is the prior art and is not described herein again.

In one embodiment, the method further comprises: if any candidate domain name is not matched with the target domain name or any corresponding IP address is not searched, requesting a designated server to acquire target IP configuration data corresponding to the target domain name;

and storing and/or updating target IP configuration data returned by the specified server to the local end.

Specifically, when the network is not good or other operating environments are not good, the requested acquired IP configuration data may be incomplete, and therefore, a candidate domain name that matches the target domain name may not be found, or a matching candidate domain name may not be found, but the corresponding IP address may not be found. At this time, the original network request has been sent, but in order to facilitate finding the target IP configuration data of the target domain name later, the target IP configuration data of the target domain name may be requested to be acquired from the specified server at this time. The purpose of this is to store the IP configuration information of the target domain name to the local terminal device, so that the target IP configuration data of the target domain name can be conveniently and quickly searched.

In one embodiment, the IP configuration data further comprises: at least one of service operator information, an expiration date of each IP address, a priority of the IP address;

the connection data includes: at least one of success and failure times of establishing the test connection, a round trip time of each establishing of the test connection, and a preset time point of each successful establishing of the test connection.

Specifically, the preset time point is a time when the connection is successful.

In one embodiment, in step S500, the step of calculating the total weight of each candidate IP address according to the preset rule, the IP configuration data corresponding to the target domain name, and the connection data of the candidate IP addresses specifically includes the following steps:

screening out undetermined IP addresses meeting screening conditions from the candidate IP addresses according to IP configuration data corresponding to the target domain name and screening rules in preset rules,

and performing sub-weight setting and weight calculation on each undetermined IP address according to the IP configuration data corresponding to the target domain name, the connection data of each undetermined IP address and a weight calculation rule in a preset rule to obtain the total weight of each undetermined IP address.

In particular, although the target domain name may contain multiple candidate IP addresses, not every candidate IP address is available. For example, the validity period of some candidate IP addresses is expired, or service operators of some candidate IP addresses are different from the current device operator of the current terminal device, and the like, these candidate IP addresses which are very easy to eliminate can be directly screened out, so that unnecessary weight calculation is avoided, only the weight of the pending IP address is calculated, the cost of weight calculation is reduced, and the target IP address is quickly screened out, so as to accelerate the network request speed.

In one embodiment, screening out an undetermined IP address meeting the screening condition from candidate IP addresses according to the IP configuration data corresponding to the target domain name and the screening rule in the preset rule includes:

if the IP configuration data corresponding to the target domain name does not contain service operator information and the valid period of each IP address, taking the candidate IP address as an undetermined IP address;

if the IP configuration data corresponding to the target domain name comprises service operator information, screening out a candidate IP address with the same service operator as the current equipment operator from the candidate IP addresses as an undetermined IP address according to the service operator information corresponding to the target domain name;

if the IP configuration data corresponding to the target domain name comprises the valid time limit of each IP address, screening out candidate IP addresses within the valid time limit from the candidate IP addresses as undetermined IP addresses according to the valid time limit of each candidate IP address corresponding to the target domain name;

and if the IP configuration data corresponding to the target domain name comprises service operator information and the valid period of each IP address, screening out candidate IP addresses which are within the valid period and have the same service operator as the current equipment operator from the candidate IP addresses as undetermined IP addresses according to the service operator information corresponding to the target domain name and the valid period of each candidate IP address.

In one embodiment, step S400 specifically includes:

if the original network request does not belong to the request in the player, intercepting the original network request by utilizing a configured URL loading system middle layer;

if the original network request belongs to the request in the player, intercepting a calling network request interface of the player in a HOOK mode to intercept the original network request.

Specifically, the original network requests that do not belong to the request in the player include Native network requests and the network requests sent by H5 in Webview.

In one embodiment, step S600 specifically includes the following steps:

if the request protocol is an http protocol, replacing a target domain name in the original network request with a target IP address, adding a host field in a request header of the original network request to obtain a first network request, and using the first network request as an updated network request, wherein the host field can be used for indicating the target domain name, the host field comprises key-value data, and the key is 'host' and the value is 'target domain name';

if the request protocol is https protocol, if the target server corresponds to a plurality of different domain names including the target domain name, constructing a mapping relation between the target IP address and the target domain name,

replacing a target domain name in the original network request with a target IP address, adding a host field in a request header of the original network request, setting a mapping relation in the original network request to obtain a second network request, and taking the second network request as an updated network request, wherein the host field comprises key-value data, and the key is 'host' and the value is 'target domain name'.

Specifically, if the domain name is the http protocol, after the original network request is updated, the first network request is sent out to complete the direct connection with the target server, so that the resolution of a service operator is bypassed, and data pollution and network threat caused by domain name hijacking are effectively avoided. The mapping relationship between the IP and the domain name may be { domain name }:443: { IP }.

If the https protocol is adopted, the terminal device needs to perform SSL/TSL handshake with the target server. In the handshake process, the terminal device needs to verify whether the target server is a trusted server.

Specifically, the terminal device sends a handshake request to a target server, the target server sends a certificate to the terminal device after receiving the handshake request, the terminal device determines whether the certificate sent by the target server is issued by a trusted authority, the terminal device checks whether a domain name carried in the certificate includes a target domain name in the network request, if the certificate is issued by the trusted authority and includes the target domain name, the target server is determined to be the trusted server, and if the certificate is not issued by the trusted authority or does not include the target domain name, the target server is determined not to be the trusted server.

The target server sends an authentication challenge to the terminal equipment, the terminal equipment receives the authentication challenge, and in the callback of the authentication challenge, the original target domain name is used for authentication and a Credential is constructed and returned to the target server side, so that the target server can verify the validity of the terminal equipment.

If one target server has a plurality of domain names, corresponding different certificates under different domain names, at this time, the terminal device may not be able to distinguish whether the certificate issued by the target server is issued by a trusted authority, and SSL/TSL handshake failure occurs. In this case, the target server may correspond to a plurality of domain names, which may cause misjudgment of the terminal device. Therefore, in order to avoid the occurrence of misjudgment, the mapping relationship between the target IP address and the target domain name needs to be added in the original network request. The mapping relationship is specifically constructed according to libcurl (library).

In an embodiment, the adding the host field to the request header of the original network request specifically includes the following steps:

and decrypting the encrypted target domain name, and adding the decrypted target domain name serving as a value and a host serving as a key to the original network request in a key-value form.

In particular, some terminal devices may audit network requests due to the fact that the installed system is unique. Therefore, the target domain name needs to be stored in plaintext, that is, encrypted, and specifically AES encryption can be used. When the host field is generated by using the target domain name, the encrypted data needs to be decrypted to obtain the target domain name, so that the detection and the verification of a special system can be avoided. The step of encrypting the target domain name may be performed at any stage after the target domain name is extracted from the original network request in step S400.

In one embodiment, the method further comprises the steps of:

if a redirection response returned by the target server is received after an updated network request or an original network request is sent to the target server, request information in the original network request is obtained, wherein the request information comprises a request head, a request body and a request mode;

extracting a redirection domain name from the redirection response;

constructing an input stream object, and generating a third network request by using the input stream object according to request information and a redirection domain name in the original network request;

adding the third network request into the circular queue as a message to be consumed, and waiting for consumption;

intercepting a third network request for consumption, and extracting a redirection domain name from the third network request;

if the redirection domain name is any candidate domain name, acquiring an IP address corresponding to the redirection domain name as a redirection candidate IP address, calculating the total weight of each redirection candidate IP address according to a preset rule, IP configuration data corresponding to the redirection domain name and connection data of the redirection candidate IP address, and taking the redirection candidate IP address with the highest total weight as a redirection target IP address;

based on the request protocol of the third network request, updating the third network request according to the redirection target IP address to obtain a fourth network request;

and sending the fourth network request to a server corresponding to the redirection domain name.

Specifically, redirection (Redirect) is to Redirect various network requests to other locations by various methods (e.g., web page redirection, domain name redirection, and routing change are also a kind of redirection of data messages via paths). If the interface of the target server is configured with redirection logic or codes, the target server returns a redirection response to the terminal after sending the network request to the target server. And the terminal receives the redirection response, which indicates that the network request is redirected. When redirection occurs, the terminal can reacquire the request information in the original network request, and copy the extracted redirection domain name and the request information into the input stream object, and the input stream object regenerates the third network request according to the redirection domain name and the request information. The third network request belongs to a new network request. The third network request is placed in a current system event sequential queue, the system can trigger the request call at a proper time, the retransmitted third network request can be intercepted as the original network request and processed as the original network request, if the redirection domain name is a candidate domain name, the redirection target IP address of the third network request is obtained, the third network request is updated according to the redirection target IP address, a fourth network request is obtained, and the terminal can send the fourth network request to a server corresponding to the redirection domain name.

And if the redirected domain name is not the candidate domain name, or the redirected domain name is any candidate domain name but any corresponding redirected candidate IP address cannot be found, sending a third network request to the server corresponding to the redirected domain name.

For a request method for redirecting the third network request corresponding to the domain name, refer to the request method of the original network request specifically, and are not described herein again.

It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
