Unity
微信登陆
AndroidJavaClass jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
AndroidJavaObject jo = jc.GetStatic<AndroidJavaObject>("currentActivity");
jo.Call("wxLogin");微信分享
AndroidJavaClass jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
AndroidJavaObject jo = jc.GetStatic<AndroidJavaObject>("currentActivity");
jo.Call("wxShare", "你分享的链接", "分享标题", "分享内容");接收微信登录授权后得到的code，以获取头像昵称等
public void funName(string code) {
//根据code值获取openid token等 以获取玩家头像 昵称
//UnityWebRequest
}AndroidStudio
一.引入wxsdk
build.gradle dependencies加入以下代码，编译引入微信sdk
implementation 'com.tencent.mm.opensdk:wechat-sdk-android-with-mta:+'二.初始化微信sdk
UnityPlayerActivity.java
public IWXAPI wxApi;
public static String appId;
// Setup activity layout
@Override protected void onCreate(Bundle savedInstanceState)
{
requestWindowFeature(Window.FEATURE_NO_TITLE);
super.onCreate(savedInstanceState);
wxInit("你的微信appid");
}
public void wxInit(String id){
appId = id;
wxApi = WXAPIFactory.createWXAPI(this, appId, false);
}三.创建必要的回调文件
android项目,如下图路径创建wxapi文件夹，文件夹名字wxapi不可变更!
wxapi文件夹下创建java脚本WXEntryActivity,如下图：
脚本名字WXEntryActivity不可变更
脚本内容如下
package com.xxx.xxx.wxapi;//wxapi前面是你的bundleID
import android.os.Bundle;
import com.ddwj.ddwz.az.UnityPlayerActivity;
import com.tencent.mm.opensdk.modelbase.BaseReq;
import com.tencent.mm.opensdk.modelbase.BaseResp;
import com.tencent.mm.opensdk.modelmsg.SendAuth;
import com.tencent.mm.opensdk.openapi.IWXAPI;
import com.tencent.mm.opensdk.openapi.IWXAPIEventHandler;
import com.tencent.mm.opensdk.openapi.WXAPIFactory;
import com.unity3d.player.UnityPlayer;
import android.app.Activity;
import android.util.Log;
public class WXEntryActivity extends Activity implements IWXAPIEventHandler{
public IWXAPI wxApi;
@Override
public void onCreate(Bundle savedInstanceState) {
final String appId = UnityPlayerActivity.appId;
wxApi = WXAPIFactory.createWXAPI(this, appId, false);
super.onCreate(savedInstanceState);
try
{
boolean handleIntent = wxApi.handleIntent(getIntent(), this);
if(!handleIntent){
System.out.println("参数不合法");
finish();
}
}
catch(Exception e)
{
e.printStackTrace();
}
}
// 微信发送请求到第三方应用时，会回调到该方法
@Override
public void onReq(BaseReq baseReq) {
}
// 第三方应用发送到微信的请求处理后的响应结果，会回调到该方法
@Override
public void onResp(BaseResp baseResp) {
Log.e("unity_2_android", "onResp: " );
System.out.println("unity_2_android微信响应" + baseResp.errCode);
switch (baseResp.errCode) {
case BaseResp.ErrCode.ERR_OK:
System.out.println("unity_2_android用户同意");
if(baseResp instanceof SendAuth.Resp)
{
SendAuth.Resp newResp = (SendAuth.Resp) baseResp;
String code = newResp.code;
//传出微信返回的code信息 到Unity处理
UnityPlayer.UnitySendMessage("unity挂载接收code值的节点名","unity用来接收code的方法名",code);
}
break;
case BaseResp.ErrCode.ERR_AUTH_DENIED:
System.out.println("unity_2_android用户拒绝授权" + baseResp.openId);
break;
case BaseResp.ErrCode.ERR_USER_CANCEL:
System.out.println("unity_2_android用户取消");
break;
}
finish();
}
}四.AndroidStudio提供给Unity调用的方法
UnityPlayerActivity.java脚本加入如下代码
public void wxLogin(){
if(null == wxApi) {
wxApi = WXAPIFactory.createWXAPI(this, appId, false);
if(null == wxApi)
{
System.out.println("微信登录失败...");
return;
}
wxApi.registerApp(appId);
}
final SendAuth.Req req = new SendAuth.Req();
req.scope = "snsapi_userinfo";
req.state = "wechat_sdk_demo_test";
wxApi.sendReq(req);
}
/**
* 分享网页类型至微信
*
* @param url 分享链接
* @param title 分享标题
* @param desc 分享内容
*/
public void wxShare(String url, String title,String desc){
Bitmap thumbBmp = BitmapFactory.decodeResource(getResources(), R.mipmap.app_icon);
shareWeb(this,appId,url,title,desc,thumbBmp);
}
/**
* 分享网页类型至微信
*
* @param context 上下文
* @param appId 微信的appId
* @param webUrl 网页的url
* @param title 网页标题
* @param desc 网页描述
* @param bitmap 位图
*/
public void shareWeb(Context context, String appId, String webUrl, String title, String desc, Bitmap bitmap) {
wxApi = WXAPIFactory.createWXAPI(this, appId, false);
// 检查手机或者模拟器是否安装了微信
if (!wxApi.isWXAppInstalled()) {
// ToastUtil.makeText("您还没有安装微信");
UnityPlayer.UnitySendMessage("PanelWallet","showTip","您还没有安装微信");
return;
}
// 初始化一个WXWebpageObject对象
WXWebpageObject webpageObject = new WXWebpageObject();
// 填写网页的url
webpageObject.webpageUrl = webUrl;
// 用WXWebpageObject对象初始化一个WXMediaMessage对象
WXMediaMessage msg = new WXMediaMessage(webpageObject);
// 填写网页标题、描述、位图
msg.title = "";
msg.description = desc;
// 如果没有位图，可以传null，会显示默认的图片
msg.setThumbImage(bitmap);
// 构造一个Req
SendMessageToWX.Req req = new SendMessageToWX.Req();
// transaction用于唯一标识一个请求（可自定义）
req.transaction = "webpage";
// 上文的WXMediaMessage对象
req.message = msg;
// SendMessageToWX.Req.WXSceneSession是分享到好友会话
// SendMessageToWX.Req.WXSceneTimeline是分享到朋友圈
req.scene = SendMessageToWX.Req.WXSceneSession;
// 向微信发送请求
wxApi.sendReq(req);
}wxLogin为微信授权登录
wxShare为微信分享
下面是我的code获取头像昵称的方法,没有整理，仅供参考
public void funName(string code) {
//授权登录后android返回的code

string nick = PlayerPrefs.GetString("nick_local");
text_wxNick.text = nick;
