微信官方文档API:https://developers.weixin.qq.com/doc/oplatform/Mobile_App/WeChat_Login/Development_Guide.html

1.申请你的 AppID

只有审核通过的应用才能进行开发。

2.下载 SDK 及 API 文档

Android Studio 环境下：

在 build.gradle 文件中，添加如下依赖即可：
dependencies {
implementation 'com.tencent.mm.opensdk:wechat-sdk-android:6.8.0'
}

3.将APP注册到微信

IWXAPI msgApi = WXAPIFactory.createWXAPI(LoginActivity.this, Constant.AppID, true);    if (msgApi.isWXAppInstalled()) {      // 将应用的appId注册到微信      msgApi.registerApp(Constant.AppID);      //建议动态监听微信启动广播进行注册到微信      registerReceiver(new BroadcastReceiver() {        @Override        public void onReceive(Context context, Intent intent) {          // 将该app注册到微信          msgApi.registerApp(Constant.AppID);        }      }, new IntentFilter(ConstantsAPI.ACTION_REFRESH_WXAPP));      final Req req = new Req();      req.scope = "snsapi_userinfo"; //获取用户个人信息则填写 snsapi_userinfo      req.state =  "mvwl-"; //可根据项目填写      msgApi.sendReq(req);    } else {      Toast.makeText(LoginActivity.this, "请安装微信客户端后进行此操作").show();      return;    }

4.创建WXEntryActivity，在AndroidMainifest.xml中添加WXEntryActivity

public class WXEntryActivity extends WXCallbackActivity  implements IWXAPIEventHandler {  public static final String WXLOGIN_ACTION = "com.mvw.test.wxlogin";  private IWXAPI iwxapi;  @Override  protected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    iwxapi = WXAPIFactory.createWXAPI(this, "自己项目APPID", true);    try {      Intent intent = getIntent();      iwxapi.handleIntent(intent, this);    } catch (Exception e) {      e.printStackTrace();    }  }  @Override  protected void onNewIntent(Intent intent) {    super.onNewIntent(intent);    setIntent(intent);    iwxapi.handleIntent(intent, this);  }  // 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) {    switch (baseReq.getType()) {      case ConstantsAPI.COMMAND_GETMESSAGE_FROM_WX:        break;      case ConstantsAPI.COMMAND_SHOWMESSAGE_FROM_WX:        break;      default:        break;    }  }  @Override  public void onResp(BaseResp baseResp) {    Intent intent = new Intent(WXLOGIN_ACTION);    //登录回调    Log.i("微信", "onResp: "+ baseResp.errCode);    switch (baseResp.errCode){      case BaseResp.ErrCode.ERR_OK:        String code = ((SendAuth.Resp) baseResp).code;        intent.putExtra("Wx_Login", code);        intent.putExtra("error_code", 0);        break;      //用户拒绝授权      case BaseResp.ErrCode.ERR_AUTH_DENIED:        intent.putExtra("error_code", -4);        break;      //用户取消授权      case BaseResp.ErrCode.ERR_USER_CANCEL:        intent.putExtra("error_code", -2);        break;    }    sendBroadcast(intent);  //使用了广播    finish();  }}

5.接收微信返回参数code,根据code获取access_token,获取用户个人信息
下面是完整的使用列子。

             } else {                // 没有access_token                getAccessToken(code);              }            }            break;          case -4: //用户拒绝授权          case -2:  //用户取消授权            Log.i("微信", "onReceive: " + error_code);
