unity接微信androidSDK,一个供参考测试的Demo

首先 搭建环境的工作我不多说, 网上可以搜到一大堆;

然后 需要用到的请求还得读一读官方文档

文档: 微信授权后http请求接口

文档:分享给好友，朋友圈

这个是微信登录授权后拉取到的用户信息

unity代码部分经过简单的封装

unity 调androidSDK  首先需要 _GetCurrentAndroidJavaObject() 得到AndroidJavaObj jo;

jo.Call(apiName, args) 中  T代表返回类型, apiName 是SDK中的函数名， args则是对应函数的

unity c#部分代码:

using UnityEngine;
using System.Collections;
using UnityEngine.UI;
using System.Collections.Generic;
using System;

public class test : MonoBehaviour {

    private Text txt;
    string headimgurl;

    // Use this for initialization
    void Start () {
        GameObject btnObj = GameObject.Find("Canvas/Button");   //获取按钮脚本组件
         Button btn = (Button)btnObj.GetComponent();
        GameObject btnObj1 = GameObject.Find("Canvas/Button1");   //获取按钮脚本组件
        Button btn1 = (Button)btnObj1.GetComponent();
        GameObject btnObj2 = GameObject.Find("Canvas/Button2");   //获取按钮脚本组件
        Button btn2 = (Button)btnObj2.GetComponent();
        GameObject btnObj3 = GameObject.Find("Canvas/Button3");   //获取按钮脚本组件
        Button btn3 = (Button)btnObj3.GetComponent();
        GameObject btnObj4 = GameObject.Find("Canvas/Button4");   //获取按钮脚本组件
        Button btn4 = (Button)btnObj4.GetComponent();
        GameObject btnObj5 = GameObject.Find("Canvas/Button5");   //获取按钮脚本组件
        Button btn5 = (Button)btnObj5.GetComponent();
        GameObject btnObj6 = GameObject.Find("Canvas/Button6");   //获取按钮脚本组件
        Button btn6 = (Button)btnObj6.GetComponent();
        GameObject textObj = GameObject.Find("Canvas/Text");   //获取按钮脚本组件
        txt = (Text)textObj.GetComponent();
        //添加点击侦听
        btn.onClick.AddListener(onClick);
        btn1.onClick.AddListener(onClick1);
        btn2.onClick.AddListener(onClick2);
        btn3.onClick.AddListener(onClick3);
        btn4.onClick.AddListener(onClick4);
        btn5.onClick.AddListener(onClick5);
        btn6.onClick.AddListener(onClick6);
    }
	
	// Update is called once per frame
	void Update () {

    {

        AndroidJavaObject jo = _GetCurrentAndroidJavaObject();
        jo.Call(apiName, args);
    }

    protected T _CallSdkApiReturn(string apiName, params object[] args)          //模板只是返回参数类型不同
    {

        AndroidJavaObject jo = _GetCurrentAndroidJavaObject();

AndoridSDK调用unity c#

UnityPlayer.UnitySendMessage("Canvas","json_AcToken",a_t_r);      Canvas是场景中的游戏对象, json_AcToken表示游戏对象中某个脚本的函数名 ， a_t_r及之后的则是参数

值得一提的是 授权后需要的http请求, 还有json的解析, 既可以写在unity中也可以写在SDK中,

这里我图方便, 刚好unity中有json类, SDK中有http类, 所以我一个写在unity中 一个写在SDK中

当然这都不是正确的作法, 出于安全考虑 app_secret,access_token等信息不应该暴露在客户端中, 所以对应的http请求应该在服务器上进行。
