Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
As shown in fig. 1, an embodiment of the present invention proposes a network data transmission method, applied to a first host, including:
step 11, receiving an access request sent by a second host communicating with the first host through a public network, wherein the access request comprises at least two sub-requests for accessing a target host; the first host and the target host are in the same virtual private network;
step 12, according to the access request, orderly and centralizing at least two sub-requests to obtain a response result of at least one target host;
and step 13, accessing at least one target host through the virtual private network according to the response result.
In the prior art, the overseas hosts O in the public cloud 1 are often faced, the internal hosts D1, D2, D3 in the public cloud 2 need to be accessed sequentially, and after the results of the sub-requests 1, 2, 3 are taken, the next action is performed, and the above process is called an atomic operation. The following two problems often occur in the application of one atomic operation: firstly, cross-border access based on public network IP has higher packet loss rate and continuous network jitter when serious; and secondly, a high concurrency but unstable network environment increases the programming difficulty for atomic operations containing 3 network requests.
In this embodiment, as shown in fig. 2, a first host is added in the application scenario, where the first host and the second host belong to the same area, and the first host and the second host are based on public network communication, and are in the same area, so that the public network cross-border problem is not faced between the first host and the second host. When a second host needs to access a plurality of cross-regional and cross-public cloud target hosts, the first host receives access requests of the second host, and orderly and centralizes the sub-requests according to the access requests to obtain a response result of at least one target host; and according to the response result, accessing at least one target host through the virtual private network (VPC). The problem of data transmission instability caused by cross-border and cross-public cloud is solved.
In an alternative embodiment of the present invention, step 12 may include:
step 121, obtaining a target parameter of an access request;
step 122, orderly accessing the target hosts of at least two sub-requests according to the preset access sequence of the target parameters;
and step 123, receiving response results of the at least two target hosts.
In this embodiment, as shown in fig. 3, the first host receives an access request of the second host, accesses three target hosts D1, D2 and D3 sequentially according to the header parameters of the access request, and obtains the response results of the three target hosts.
In an alternative embodiment of the present invention, step 13 may include:
step 131, collecting the response results according to the preset access sequence to obtain a response list;
step 132, serializing the response list to obtain response information of the first host;
and step 133, transmitting the response information of the first host to the second host.
In this embodiment, as shown in fig. 3, the response results of the three target hosts are grouped into a response list according to the order of D1, D2, and D3, the response list is serialized to obtain the response result of the first host, and the response result is sent to the second host.
In an alternative embodiment of the present invention, step 131 may include:
step 1311, receiving response results respectively fed back by the first target host to the nth target host, where N is a positive integer;
step 1312, sorting the received response results according to the preset access sequence to obtain a response list, where the response result receiving sequence from the first target host to the nth target host is different from the preset access sequence.
In this embodiment, the response results are different from the preset access sequence due to reasons such as the network, so that the response results of the multiple target hosts need to be collected according to the preset access sequence to obtain the response list.
In an alternative embodiment of the present invention, step 132 may include:
step 1321, processing the response results from the first target host to the nth target host according to the preset access sequence and the preset sequence format to obtain response information of the first host.
In this embodiment, the response list is processed according to a transmission protocol supporting format between the first host and the second host, so as to obtain response information of the first host.
In an alternative embodiment of the present invention, step 132 further includes:
step 1322, detecting the response results from the first target host to the nth target host, and determining an abnormal response result record;
and 1323, respectively performing packaging processing on the abnormal response result record and the normal response result according to the preset access sequence and the preset sequence format to obtain the response information of the first host.
In this embodiment, an abnormal processing result is detected for the response information, a log is recorded, and then, the abnormal response result record and the normal response result are respectively packaged to obtain the response information of the first host.
In an alternative embodiment of the present invention, step 133 may include:
step 1331, after encoding the response information of the first host according to a preset scripting language, sending the encoded response information to the second host, where the communication protocol of the public network supports the preset scripting language.
As shown in fig. 2, in the above embodiment of the present invention, by adding an extra-environment server T in the public cloud 2, the same area as the extra-environment host O is provided, so that the access from the host O to the host T is not cross-border any more, and the network quality can be effectively ensured even based on the public network. Meanwhile, a special network VPC is additionally arranged in the public cloud 2 to connect an overseas host T with an in-home host group, and the network environment can be ensured by borrowing infrastructure of the public cloud in the public cloud although the hosts cross the environment. On the premise that the network can be ensured, the ordered sub-requests Req1, req2 and Req3 of the hosts D1, D2 and D3 can be achieved by pre-compiling a Lua (a scripting language) module in the nmginx (a server software) of the host T, and then by the Lua script. By the method, the 3 public network cross-border requests from the original host O to the hosts D1, D2 and D3 are changed into the non-cross-border requests from the host O to the host T, and the non-cross-border requests are forwarded to the hosts D1, D2 and D3 by the host T through the VPC private network. The response results of the requests are returned to the host computer T in the same way, and are returned to the host computer O after being processed by the Lua script on the host computer T. The method not only improves the network processing efficiency of the atomic service operation and provides more possibility for high concurrency, but also ensures that the logic of the service on the host O is simpler and clearer.
The Lua script code is as follows:
# nginx.conf
http {
server {
listen 80;
location /sequential {
content_by_lua_block {
local http = require "resty.http"
local cjson = require "cjson"
local target_urls = {
"http://target1.example.com",
"http://target2.example.com",
"http://target3.example.com"
}
local httpc = http.new()
local responses = {}
for _, target_url in ipairs(target_urls) do
local res, err = httpc:request_uri(target_url, {
method = ngx.HTTP_GET
})
if res then
table.insert(responses, res.body)
else
ngx.log(ngx.ERR, "Failed to request: ", err)
end
end
ngx.status = 200
ngx.header.content_type = "application/json"
ngx.say(cjson.encode({ responses = responses }))
}
}
}
}
