Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
It should be understood that the described embodiments are only some embodiments of the invention, and not all embodiments. 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 invention.
In order to better understand the instant message transmission method provided by the embodiment of the present invention, an application scenario of the instant message transmission method provided by the embodiment of the present invention is briefly introduced first.
In the embodiment of the invention, the users can communicate with each other through instant messages, and the instant messages among different users can be transmitted and forwarded through the data center. The data center may include a series of services for instant message forwarding. In order to smoothly use these services for the instant message transmission and reception service, the terminal may establish a long connection prior to a long connection server under the data center. Based on the long connection service, various types of specific service forms can be established, such as single chat, group chat, live broadcast room and the like.
In a first aspect, an embodiment of the present invention provides a method for establishing a long connection service, which is based on a first data center, and enables instant message transmission between users to be more timely.
As shown in fig. 1, an embodiment of the present invention provides a method for establishing a long connection service, where based on a first data center, the method includes:
s11, receiving a long connection server address query request sent by a terminal, wherein the long connection server address query request carries the position information of the terminal; the terminal is located in the service range of the first data center;
in the embodiment of the invention, before the terminal carries out instant message communication, a long connection is required to be established with the long connection server. Specifically, since the terminal is within the service range of the first data center, the terminal can establish a long connection with one long connection server under the first data center.
In order to enable the terminal to establish a long connection with an appropriate long connection server, in this step, an address query request of the long connection server sent by the terminal may be received, where the query request carries the location information of the terminal. Alternatively, the location information may include various information capable of indicating the location of the terminal, such as GPS (global positioning system) information, IP address information, and the like.
S12, generating a long connection server address list corresponding to the terminal according to the position information of the terminal, wherein the long connection server address list comprises address information of at least one long connection server under the first data center; the distance between the at least one long connection server and the terminal is smaller than a preset threshold value;
in this step, after receiving the long connection server address query request, the long connection server address list corresponding to the terminal may be generated according to the location information of the terminal carried in the query request. The address list of the long connection server may include address information of one or more long connection servers under the first data center, and a distance between the long connection servers and the terminal is smaller than a preset threshold. Alternatively, the address information in the address list may include IP address information of the long connection server and identification information of a port in the long connection server that provides the long connection service.
That is, in the embodiment of the present invention, the first data center may include a plurality of long connection servers, and the long connection servers may be located in different regions and have different address information. In order to provide a more timely instant messaging service for a terminal, in the embodiment of the present invention, before the terminal establishes a long connection with a long connection server, address information of the long connection server near the terminal may be provided to the terminal in the form of an address list, so that the terminal can preferentially establish the long connection with the long connection server having a shorter distance.
S13, sending the address list of the long connection server to the terminal, so that the terminal establishes a long connection with the corresponding long connection server according to the address list of the long connection server.
After the address list of the long connection server is generated, the address list can be sent to the terminal in the step, so that the terminal establishes long connection with the corresponding long connection server according to the address information in the address list of the long connection server.
The method for establishing the long connection service provided by the embodiment of the invention can receive a long connection server address query request sent by a terminal, generate a long connection server address list corresponding to the terminal according to the position information of the terminal carried in the long connection server address query request, wherein the address list comprises the address information of at least one long connection server under the first data center, and the distance between the at least one long connection server and the terminal is less than a preset threshold value, and then send the long connection server address list to the terminal so that the terminal establishes long connection with the corresponding long connection server according to the long connection server address list. Therefore, the address information of one or more connectable long connection servers can be provided for the terminal according to the address query request of the long connection server sent by the terminal, and the distance between the provided long connection servers and the terminal is smaller than the preset threshold value, so that the terminal can establish long connection with the long connection server which is closer to the terminal, and the timeliness of instant message transmission is effectively improved.
Alternatively, in step S12, the long connection server address list may be generated in a variety of ways. For example, in an embodiment of the present invention, generating the long connection server address list corresponding to the terminal according to the location information of the terminal may specifically include:
according to the position information of the terminal, acquiring address information of at least two long connection servers, wherein the distance between the first data center and the terminal is smaller than the preset threshold value;
and after the address information of the at least two long connection servers is sequenced from near to far from the terminal, the address list of the long connection servers is generated.
For example, in an embodiment of the present invention, the location information of the terminal is pos0, and the first data center has 5 long connection servers sv1, sv2, sv3, sv4, sv5, where a distance between sv1, sv4, sv5 and the location pos0 of the terminal is less than a preset threshold (the preset threshold is, for example, 500 km). Then, address information of sv, sv4 and sv5 can be acquired, and if sv1 is away from pos 080 kilometers, sv4 is away from pos 0450 kilometers, and sv5 is away from pos 0240 kilometers, then address information of sv1, sv4 and sv5 can be sorted according to the order of sv1, sv5 and sv4, so as to generate a long connection server address list.
Optionally, the long connection server address query request received in step S11 may be in various request forms, as long as the corresponding APIs (application programming interface) of the terminal and the server are agreed in advance. For example, in an embodiment of the present invention, the query request for the long connection server address may include a target domain name address, for example, a domain name address of an http (hyper text transport protocol) type, and based on this, in step S12, generating the long connection server address list corresponding to the terminal according to the location information of the terminal may specifically include:
resolving the target domain name address into address information of a plurality of long connection servers;
and according to the position information of the terminal, selecting the address information of at least one long connection server with the distance from the terminal being smaller than the preset threshold value from the analyzed address information of the plurality of long connection servers to obtain the address list of the long connection servers.
For example, in one embodiment of the present invention, the received long connection server address query request includes the domain name address http: if/available server inquiry, the address information of a plurality of long connection servers, such as addrl, addr2 and addr3, is analyzed according to the query request, and then the address information of the long connection server, such as addr3, whose distance from the terminal is less than a preset threshold (the preset threshold is 200 kilometers, for example), is selected from the address information, so as to obtain the address list of the long connection server.
That is, in the embodiment of the present invention, DNS (domain name system) intelligent resolution may be performed on the API interface domain name, and according to the area where the user terminal is located, the domain name can be flexibly and accurately reached to the country, province, city, and the like, the data center area to be accessed is divided for the user, so that the user preferentially accesses the relatively long connection server to perform data processing.
Optionally, in the embodiment of the present invention, the address list of the long connection server may include address information of one long connection server or a plurality of long connection servers. In the case that the address information of a plurality of long connection servers is included, the terminal can select one server with the best effect from the servers to establish the long connection, and the terminal can also switch the connection among the plurality of long connection servers.
In the above embodiment, the distances between the long connection servers in the address list and the terminal are all smaller than the preset threshold, but the embodiment of the present invention is not limited thereto. In another embodiment of the present invention, the address list may include all long-connection servers within the service range of the first data center, wherein the recommended priority of the long-connection server whose distance from the terminal is greater than the preset threshold is lower than that of the long-connection server whose distance from the terminal is less than the preset threshold.
Optionally, in an embodiment of the present invention, the recommended priority of the long connection servers in the address list may be gradually decreased according to a sequence from near to far of each long connection server from the terminal. Therefore, on one hand, the terminal can be guaranteed to be preferentially accessed to the long connection server with the shorter distance, and on the other hand, when the long connection server with the shorter distance cannot normally serve, the terminal can be served through other long connection servers in the service range of the first data center.
Further, in the above embodiment, the address information in the address list of the long connection server is in the service range of the first data center, and since the long connection servers are in the same data center, it is easier to respond to the address query request sent by the terminal. However, embodiments of the invention are not limited thereto, and in other embodiments of the invention, the long connection server address list may also include address information of long connection servers within other data center service ranges.
Specifically, in an embodiment of the present invention, before sending the long connection server address list to the terminal in step S13, the method for establishing a long connection service provided in the embodiment of the present invention may further include:
acquiring address information of at least one long connection server under a second data center by calling a preset program interface, wherein the second data center is different from the first data center;
and adding the address information of at least one long connection server under the second data center into the address list.
For example, the long connection server B of the second data center provides a preset program interface, and when the long connection server a of the first data center calls the preset program interface, the address information of the long connection server B of the second data center and/or other long connection servers in the second data center can be obtained. Thus, each data center can flexibly grasp the state information of the long connection servers of other data centers. By performing state synchronization on each data center at regular time, the information of the newly-increased connection server and the failed connection server can be synchronized to other data centers relatively in real time.
Optionally, in the embodiment of the present invention, address information of the long connection server in the second data center may be obtained according to various policies (for example, a random extraction policy or a physical location far and near policy), and the address information may be added to the address list.
Further, in an embodiment of the present invention, the long connection server a may further send the acquired address information of the long connection server in the second data center to a response server of the address query request (for example, a preset domain name resolution server), and when the terminal sends the address query request of the long connection server to the response server, the response server may also provide the address information of the long connection server in the second data center to the terminal.
In a second aspect, an embodiment of the present invention further provides a method for establishing a long connection service, which enables instant message transmission between users to be more timely based on a terminal.
As shown in fig. 2, an embodiment of the present invention provides a method for establishing a long connection service, where, based on a terminal, the terminal is located in a service range of a first data center, the method may include:
s21, sending a long connection server address query request to a first data center, wherein the long connection server address query request carries the position information of the terminal;
in the embodiment of the invention, before the terminal carries out instant message communication, a long connection is required to be established with the long connection server. Specifically, since the terminal is within the service range of the first data center, the terminal can establish a long connection with one long connection server under the first data center.
In order to establish a long connection with a suitable long connection server, in this step, the terminal may first send a long connection server address query request to the first data center (for example, to an address query server under the first data center), where the query request may carry location information of the terminal. Alternatively, the location information may include various information that can indicate the location of the terminal, such as GPS information, IP address information, and the like.
S22, receiving a long connection server address list sent by the first data center, where the long connection server address list includes address information of at least one long connection server in the first data center; the distance between the at least one long connection server and the terminal is smaller than a preset threshold value;
in this step, the first data center may determine, according to the address query request of the long connection server sent by the terminal, address information of one or more long connection servers whose distance from the terminal is smaller than a preset threshold, to form a long connection server address list. The terminal may receive the list of long connection server addresses from the first data center.
And S23, establishing long connection with the corresponding long connection server according to the address list of the long connection server.
In this step, the terminal may establish a long connection with the corresponding long connection server according to the long connection server address in the long connection server address list. Optionally, when only one long connection server address exists in the address list, the terminal may directly establish a long connection with the long connection server, and when a plurality of long connection servers exist in the address list, the terminal may select one long connection server from the long connection servers according to a preset policy to establish the long connection.
According to the method for establishing the long connection service, the terminal can send the address query request of the long connection server to the first data center, receive the address list of the long connection server sent by the first data center, and establish long connection with the corresponding long connection server according to the address list of the long connection server. Because the address query request of the long connection server carries the position information of the terminal, the first data center can determine the address information of each long connection server in the address list of the long connection server according to the position information of the terminal, so that the distance between the long connection server in the address list of the long connection server fed back to the terminal and the terminal is smaller than a preset threshold value, the terminal can establish long connection with the long connection server which is closer to the terminal, and the timeliness of instant message transmission is effectively improved.
Optionally, in an embodiment of the present invention, the address information of the first data center in the address list of the long connection server received in step S22 may be arranged in order from near to far from the terminal; then, in step S23, according to the long connection server address list, establishing a long connection with the corresponding long connection server may specifically include: and according to the arrangement sequence of the address information, trying to establish long connection with the long connection server corresponding to the address information in sequence until the long connection is established successfully. That is, the terminal may preferentially establish a long connection with a long connection server closest to itself, and if the establishment is unsuccessful, attempt to establish a long connection with a long connection server next closest to itself.
