准备工作（APP_ID等参数官网上教程很全）

需要注意包名及签名是否正确

creator 连接 Android 代码

jsb.reflection.callStaticMethod(“org/cocos2dx/javascript/AppActivity”, “StartWeiXin”, “()V”);
在这里插入图片描述

creator 接收 Android 回调

//第三方回调
window.onGameLoginRsp = 
    // 登录回调
    function(code) 
    {
        //请求token
        let request = loader.getXMLHttpRequest();
        var url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid="  + PublicDefine.AppIDWX + "&secret=" + PublicDefine.AppSecretWX + "&code=" + code + "&grant_type=authorization_code";
        request.open("GET" , url,true) ;
        request.onreadystatechange = function()
        {
            if( request. readyState == 4 && (request. status >= 200 && request. status < 300))
            {
                let response = request.responseText;
                console.log (response);
                var responseJson = JSON. parse (response)
                if(responseJson.access_token)
                {
                    //请求玩家信息
                    var requestInfo = loader.getXMLHttpRequest();
                    var url = "https://api.weixin.qq.com/sns/userinfo?access_token="  + responseJson.access_token + "&openid=" + responseJson.openid;
                    SceneManager.getInstance().showWaitLayer();
                    console.log(url);
                    requestInfo. open("GET" , url,true) ;
                    requestInfo . onreadystatechange = function()
                    {
                        if( requestInfo. readyState == 4 && (requestInfo. status >= 200 && requestInfo. status < 300)) 
                        {
                            var response = requestInfo.responseText;
                            cc.log("Pando: sendHttpGet second ");
                            console.log (response);
                            var responseJson = JSON. parse (response)
                            if(responseJson){ }
                        }
                    }
                    requestInfo.send( );
                }
            }
        }
        request.send();
    };

Android studio 修改

build.gradle 文件 dependencies 引用微信Android sdk

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar','*.aar'])
    implementation fileTree(dir: "F:/CocosCreator/2.2.2/resources/cocos2d-x/cocos/platform/android/java/libs", include: ['*.jar'])
    implementation project(':libcocos2dx')

    api 'com.tencent.mm.opensdk:wechat-sdk-android-without-mta:+'
}

在这里插入图片描述

微信API

获取IWXAPI的实例并将应用的appId注册到微信

api = WXAPIFactory.createWXAPI(this, ConstInfo.APP_ID, true);
 // 将应用的appId注册到微信
api.registerApp(ConstInfo.APP_ID);

AppActivity 中onCreate 下

 /** 微信授权 */
    public static void StartWeiXin() {
        System.out.println("Pando: StartWeiXin");
        SendAuth.Req req = new SendAuth.Req();
        req.scope = "snsapi_userinfo";
        req.state = "order";
        api.sendReq(req);
    }

WXEntryActivity 建立

注意 WXEntryActivity 路径问题你的包名.wxapi.WXEntryActivity 在这里插入图片描述
回调cocos方法可能出现参数问题字符串一定补充好 \" 否则会报错

@Override
	public void onResp(BaseResp resp) {
		System.out.println("Pando:----resp type " + resp.getType() + ", resp code " + resp.errCode);

		// 授权
		if (resp.getType() == ConstantsAPI.COMMAND_SENDAUTH) {
			if (resp.errCode == BaseResp.ErrCode.ERR_OK) {
				final SendAuth.Resp authResp = (SendAuth.Resp)resp;
				// 授权成功回调
				System.out.println("Pando: StartWeiXin success");
				Cocos2dxHelper.runOnGLThread(new Runnable() {
					@Override
					public void run() {
						String funCocos = "onGameLoginRsp(\"" + authResp.code + "\")";
						System.out.println(funCocos);
						Cocos2dxJavascriptJavaBridge.evalString(funCocos);
					}
				});
			} else {
				// 授权失败回调
				System.out.println("Pando: StartWeiXin fail");
			}
		}
        finish();
	}
