Unity之HTTP通讯

一 , Unity Http简单封装

using System;
using System.Collections;
using System.Collections.Generic;
using System.Text;
using UnityEngine;
using UnityEngine.Networking;

public class HttpNetMgr
{
    public enum MethodType
    {
        GET,
        POST
    }

    public class DownloadHanlderType
    {
        public const string kHttpBYTE = "BYTE";
        public const string kHttpTEXT = "TEXT";
    }

    public static IEnumerator HTTPRequest(string url, Dictionary<string, object> param, MethodType methodType, Action<object> callback, string dateType = "TEXT")
    {
        UnityWebRequest request = null;
        Debug.Log("OKOKOK");
        switch (methodType)
        {
            case MethodType.GET: request = UnityWebRequest.Get(HttpNetMgr.CreateGetData(url, param)); break;
            case MethodType.POST: request = UnityWebRequest.Post(url, HttpNetMgr.CreatePostData(param)); break;
        }
        request.SetRequestHeader("Content-Type", "application/x-www-form-urlencoded");//加入header
        yield return request.SendWebRequest();
        if (request.isHttpError || request.isNetworkError)
        {
            Debug.LogErrorFormat("Request Error: {0}", request.error);
        }
        if (request.isDone)
        {
            if (dateType == DownloadHanlderType.kHttpTEXT)
            {
                callback?.Invoke(request.downloadHandler.text);
            }
            else if (dateType == DownloadHanlderType.kHttpBYTE)
            {
                callback?.Invoke(request.downloadHandler.data);
            }
        }
    }

    private static string CreateGetData(string url, Dictionary<string, object> form)
    {
        string data = "";
        if (form != null && form.Count > 0)
        {
            foreach (var item in form)
            {
                data += item.Key + "=";
                data += item.Value.ToString() + "&";
            }
        }
        if (url.IndexOf("?") == -1)
            url += "?";
        else
            url += "&";

        url += data.TrimEnd(new char[] { ‘&‘ });
        return url;
    }

    private static WWWForm CreatePostData(Dictionary<string, object> formData)
    {
        WWWForm form = new WWWForm();
        if (formData != null && formData.Count > 0)
        {
            foreach (var item in formData)
            {
                if (item.Value is byte[])
                    form.AddBinaryData(item.Key, item.Value as byte[]);
                else
                    form.AddField(item.Key, item.Value.ToString());
            }
        }
        return form;
    }
}

二, 请求Http

    void Start()
    {
        Debug.Log("START!!!!!!");
        Dictionary<string, object> param = new Dictionary<string, object> {
            { "p1","Pa"} , { "p2", "Pb"}
        };
        StartCoroutine(
                    HttpNetMgr.HTTPRequest("http://127.0.0.1:8980/test", param, HttpNetMgr.MethodType.GET, msg =>
                    {
                        Debug.Log(msg.ToString());
                    }, "TEXT")
            );

    }
