Explanation:
The recent project is a Webgl project, including the front end (Webgl) + database. Here, I use Node.js as the middleware to encapsulate the GET and POST interfaces to operate the database. Another point is that the server only opens one port to the outside world. If you want to process the logic of multiple interfaces through one port (Webgl uses port 80, and Node.JS listens on port 3000), here is the Nginx reverse proxy, which has not been used for many things, but also encountered Lots of questions.
Directly use node.js to encapsulate the interface API to test GEt and POST requests without any problems. After adding Nginx, it is found that the form data of the POST request is null after being sent to the server, indicating that the front-end logic should be no problem. The main solution is in the Nginx configuration Start with the front-end test code first:
//测试
public void TestData(WWWForm form, Action<bool> callback)
{
StartCoroutine(TestData_IE(form, callback));
}
//使用了Nginx：http://1.117.228.127:80/updateData
//不使用Nginx: http://1.117.228.127:3000/updateData
IEnumerator TestData_IE(WWWForm form,Action<bool> callback)
{
using (UnityWebRequest request=UnityWebRequest.Post("http://1.117.228.127:80/updateData", form))
{
yield return request.SendWebRequest();
if (!string.IsNullOrEmpty(request.error))
Debug.LogError(request.error);
Debug.Log(request.downloadHandler.text);
if (request.downloadHandler.text=="true")
{
callback(true);
}
else
{
callback(false);
}
}
}
}
The server
is related to the server and Windows Server 2012R2the database. MySQLHere I use the PHPStudy integrated environment software, which is more friendly to those who are not familiar with the back end like me. Here is to start the Nginx service.
Then modify its corresponding configuration file. Click to open the Nginx root directory, find the conf folder and enter to find the nginx.conf file, which is the Nginx configuration file.
Start to nginx.confconfigure, the server part in the code is the related configuration added.

The configuration here is that the outside world listens to port 80, and external users access related requests on port 80. For example http://1.117.228.127:80/Test, Nginx will automatically turn to the GET request http://127.0.0.1:3000/Test, because the initial requirement is to open only one port to the outside world, here Realized opening a port 80 to the outside world, and then performed reverse proxy.
Problems encountered:
Nginx反向代理对POST请求的表单数据，服务器打印测试一直为null
This is a simple configuration at the beginning
location /Test/ {
proxy_pass http://127.0.0.1:3000/Test/;
}
location /updateData/{
proxy_pass http://127.0.0.1:3000/updateData;
}
In the modified configuration, two points have been modified here, and then the POST is successful.
First, after location /updateData /, remove
the second, add some settings
location /Test/ {
proxy_pass http://127.0.0.1:3000/Test/;
}
location /updateData{
proxy_pass http://127.0.0.1:3000/updateData;
proxy_redirect off;
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
proxy_redirectThis command is used to modify the Location header field and "refresh" header field in the response header returned by the proxy server.
proxy_set_headerIt is used to redefine the request header sent to the backend server. When the Host is set to $http_host, the value of the request header will not be changed.
