微信官方文档API:https://developers.weixin.qq.com/doc/oplatform/Mobile_App/WeChat_Login/Development_Guide.html
申请你的 AppID
只有审核通过的应用才能进行开发。
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'
}
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; }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" />接收微信返回参数code,根据code获取access_token,获取用户个人信息
