The embodiment of the disclosure provides a network connectivity diagnosis method, which is used for a terminal, and the terminal in the embodiment of the disclosure can be a mobile phone, a tablet or a computer and other network-connectable equipment. As shown in fig. 1, fig. 1 is a flowchart of a network connectivity diagnosis method according to an embodiment of the present disclosure, including the following steps:
s11: determining whether the network request to the target server failed;
in embodiments of the present disclosure, a network request failure may refer to a failure to successfully establish a network connection with a target server. In the event of a network request failure, data cannot be sent to or received from the target server.
S12: detecting an application layer request after the network request fails;
in the embodiment, the application layer is the top layer of the seven-layer protocol of the network, so if the target server can respond to the request of the application layer, the network state is normal and the target server state is normal, and the network request failure occurred before is probably caused by the network fluctuation for a short time only, and without any processing, i.e. if the result of the detection of the application layer request is normal, no other detection is needed, and S16 can be directly executed.
S13: if the application layer requests the detection result to be abnormal, network detection with a target server is carried out;
in this embodiment, if the application layer request fails, it indicates that there is a high possibility of a failure in the network link (network), and then a network detection is performed, and if the result of the network detection is normal, it indicates that there is a network that can communicate with the target server, and at this time, S16 can be directly performed without performing other detections.
S14: if the result of the network detection is abnormal, the network equipment detection is performed;
in this embodiment, when the result of the network detection is abnormal, it indicates that there is a problem in the network link between the terminal and the target server, and usually the terminal and the target server are not directly connected but are connected after forwarding through a plurality of network devices. If there is a problem with the network device, S16 may be directly performed.
S15: if the detection result of the network equipment is normal, performing state detection on the target server;
in the present embodiment, the possibility of failure of the terminal network and the network device has been eliminated by performing S12-S15, and therefore the most probable cause of failure of the network request is the abnormality of the target server status, and thus the target server status detection is required.
S16: and (5) integrating all detection results to determine the reason of the network request failure and sending prompt information.
In the embodiment of the present disclosure, the sent prompt message is used to indicate the reason for the network request failure, for example, the prompt message may indicate whether the network request failure is caused by the network status abnormality, the network request failure is caused by the network device abnormality, or the network request failure is caused by the target server status abnormality. In the embodiment provided by the disclosure, after a network request fails, according to preset logic steps, whether a network state is abnormal or not is determined, whether a network device is abnormal or not is determined, whether a target server is abnormal or not is determined, whether the next detection is executed depends on the result of the previous detection instead of executing various detections blindly, corresponding detections are sequentially executed according to a preset logic sequence, and the detection results are gradually deeply and comprehensively judged, so that a user is helped to quickly and accurately determine the reason of the network request failure, and the user experience is improved.
In some embodiments of the present disclosure, performing application layer request detection comprises: sending an http request to the target server; if the response of the target server to the http request is received, the result of the application layer request detection is normal; and if the response of the target server to the http request is not received, the detection result of the application layer request is abnormal.
In this embodiment, the http (Hyper Text Transfer Protocol) request may be a get request or a post request. The http request belongs to a request of an application layer, so that the influence caused by network fluctuation is avoided, the http request can be sent to the target server for multiple times, and the http detection result is determined according to multiple response results. If the http request detection result is normal, the network state is normal and the target server state is normal, and the reason for the network request failure may be accidental network fluctuation.
In some embodiments of the present disclosure, performing network detection with a target server includes: sending a display back request to a target server; if the response of the target server to the echoing request is received within a preset time length, the result of the network detection is normal; and if the response of the target server to the echoing request is not received within the preset time length, the result of the network detection is abnormal.
In this embodiment, the Ping command may be used to send a playback request to the target server, and if the target server receives the playback request, the target server may automatically reply and return a response to the playback request. The Ping command is in the application layer, and corresponds to an application program, but directly uses ICMP (Internet Control Message Protocol) of the network layer, and when a response to the echo request can be received, it indicates that the network state is normal.
In some embodiments of the present disclosure, performing network device detection includes: carrying out route tracing, and marking each network device passing from the terminal to the target server; determining whether each network device is abnormal; if the states of the network devices are normal, the detection result of the network device is normal; and if the state of any one network device is abnormal, the detection result of the network device is abnormal.
In this embodiment, when the echo request is sent to the target server but no response is received, it indicates that the network link from the terminal to the target server is at least partially interrupted, and there may be a network device that has a failure, and therefore, it is necessary to perform route tracing. The direct connection is not between the terminal and the target server, the network link between the terminal and the target server needs to pass through a plurality of network devices, namely, the data sent from the terminal needs to be forwarded by the plurality of network devices in sequence to reach the target server, therefore, when the terminal cannot establish the network connection with the target server, the routing tracking is needed to be carried out for the reason that a certain one or a plurality of network devices are failed, and the marking of each network device comprises the following steps: sending data to each network device detects the ip address and response time to each network device to determine whether any network device has failed. When the terminal is a terminal equipped with a windows system, a tracert command in the console can be adopted for carrying out route tracking, and if the terminal is a terminal equipped with a linux system, a traceroute command can be adopted for carrying out route tracking. Optionally, the return result sent by the route chase includes ip addresses and response times of the network devices. For example, if the terminal is connected to the target server sequentially through the router a and the router b, and the access timeout of the router b is found after the routing tracking is adopted, it is assumed that the router b is abnormal and cannot normally access the target server.
In some embodiments of the present disclosure, performing target server state detection includes: trying to connect a preset public website; and if the preset public website is successfully connected, determining that the state of the target server is abnormal.
In some embodiments of the present disclosure, the preset public website refers to a website with higher stability, such as an official website of a government, and a server corresponding to the website basically does not fail, so as long as the network state is normal, the public website can be accessed, and therefore, after successfully connecting to the preset public website, it is indicated that the reason for the network request failure is that the server state is abnormal, but not the network state is abnormal.
In some embodiments of the present disclosure, performing target server state detection further includes: after the target server is determined to be abnormal, acquiring a domain name server address; and judging whether domain hijacking occurs according to the acquired domain name server address.
When a user accesses a network, the user often accesses the network not by directly adopting an ip address, but by adopting a domain name access mode, a corresponding relationship between a domain name and the ip address is stored in a domain name server, and when domain name hijacking occurs, the terminal is connected to an illegal domain name server, so that the ip address corresponding to the domain name cannot be correctly obtained, but a false ip address is obtained, and a target server cannot be accessed. Optionally, after determining that domain hijacking occurs, the domain name server address is modified to a preset domain name server address.
In some embodiments of the present disclosure, performing target server state detection further includes: if the domain name hijacking does not occur, acquiring all uniform resource locators corresponding to the target server; attempting to connect to the respective uniform resource locators of the target server.
In some embodiments of the present disclosure, the target server may be deployed in multiple machine rooms, and therefore, one target server may correspond to multiple uniform resource locators, and when the target server cannot be normally accessed, only part of the uniform resource locators of the target server may be normally accessed, and at this time, by accessing each uniform resource locator of the target server, it may be known whether the machine room in which the target server is deployed cannot be accessed or part of the machine room cannot be accessed.
In some embodiments of the present disclosure, determining whether the network request to the target server failed comprises: and if n successive attempts to connect the target server fail, determining that the network request fails, wherein n is a positive integer not less than 1. In this embodiment, the terminal fails to establish a connection with the target server n consecutive times and recognizes that the network request has failed.
In some embodiments of the present disclosure, determining whether the network request to the target server failed comprises: and if the preset instruction is received, determining that the network request fails. In this embodiment, the terminal and the target server may be capable of being normally connected, this embodiment may be applied to a case where other terminals cannot access the target server, and when other terminals cannot access the target server, in order to accurately determine the reason why other terminals cannot access the target server, the target server may send a preset instruction to the terminal, so that the terminal detects whether the terminal can normally connect the target server, thereby helping to determine the reason why other terminals cannot connect the target server.
Some embodiments of the present disclosure further provide a composition diagram of a network connectivity diagnostic apparatus, where the network connectivity diagnostic apparatus in this embodiment is used for a terminal, as shown in fig. 2, the network connectivity diagnostic apparatus includes:
a determining unit for determining whether the network request to the target server fails;
