Analysis of the process of interaction implementation of UnityWebRequest front and back end

1. Technical Overview

1. Describe what this technology does?

It is a network tool library for Unity, used to make Http requests

2. Why do you learn this technology?

Project needs to prevent the use of C# native network libraries and speed up development

3. What are the difficulties in technology?

Unity only provides basic functions, and how to construct these functions into a process that can stabilize business development is a relatively difficult problem.

2. Technical details

Describe how you implemented and used the technology, requiring detailed descriptions with code and flowcharts.

HttpCenter class: encapsulate Get, Post, Put, Delete, and maintain a request queue

///Get method exampleprivate IEnumerator StartGet(HttpRequest request)
    {
      var url =  + "?";
      //Reflection is used to fill Url      Type type = ();
      var Msg = (, type);
      PropertyInfo[] properties = ().GetProperties();
      for (int i = 0; i &lt; ; i++)
      {
        url += $"{properties[i].Name}={properties[i].GetValue(Msg)}";
        if (i !=  - 1)
          url += "&amp;";
      }
       = url;
      using (UnityWebRequest www = ())
      {
         = new AcceptAllCertificatesSignedWithASpecificKeyPublicKey();
         = new DownloadHandlerBuffer();
        ("Content-Type", "application/json");
        ("token", token);
        yield return ();
        DealResult(www, request);
      }

How to use in the project: encapsulate requests, data, register delegates, call delegates and add callbacks

  // Partial package  public Action&lt;LoginMsg, Action&lt;HttpResponds&gt;&gt; NetLogin;
  public class LoginMsg : BaseMsg
  {
  public LoginMsg(string username, string password)
  {
     = username;
     = password;
  }
  public string username { get; set; }
  public string password { get; set; }
  }
  public class HttpResponds
  {
    public string data;
    public RespondsResult Result;
    public string token;
  }
  //Registering Entrustment  AddListener(ref , , "User/login");
  private void AddListener&lt;T&gt;(ref Action&lt;T,Action&lt;HttpResponds&gt;&gt; registerEvent,Method methodType,string url) where T:BaseMsg
  {
    registerEvent += (request, callback) =&gt;
    {
      HttpRequest httpRequest = new HttpRequest()
      {
        Msg = request,
        HttpMethod = ,
        Url =  + url,
        Handler = (responds) =&gt;
        {
          if ( == )
          {
            try
            {
              callback(responds);
            }
            catch(Exception ex)
            {
              
              ("The window has been destroyed");
              if(nowScene == 0)
              {
                (1);
              }
              else
              {
                (0);
              }
            }
          }
        }
      };
      (httpRequest);
    };
  }
  ///Call, add callback  (msg, (responds) =&gt;
       {
          = ;
         GetUserMsg userMsg = new GetUserMsg();
         (userMsg, (getUserResponds) =&gt;
         {
            = &lt;User&gt;();
           ("PersonalFrame");
         });
       });

3. Problems encountered in technology use and solutions

There is a strange problem in WebRequest, which I haven't understood yet, but there is a temporary solution. The problem is that the Post method is set directly ineffective, and it needs to be declared as Put first, and then =;

4. Summary

It mainly uses UnityWebRequest to make some encapsulation, use reflection, delegate and other features to achieve some basic functions.
