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();
}
}<activity android:configChanges="keyboardHidden|orientation|screenSize" android:exported="true" android:name=".wxapi.WXEntryActivity" android:theme="@android:style/Theme.Translucent.NoTitleBar" />
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
