如何获得微信授权令牌？

Question

目标:获取我需要发送到应用服务器的令牌

问题:注册返回true,请求完成返回true,但onReq并onResp没有被调用.这是代码:

public class WeChatActivity extends Activity implements IWXAPIEventHandler {

    private static final String APP_ID = ;
    private IWXAPI api;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_signin);

        api = WXAPIFactory.createWXAPI(this, APP_ID, true);
        api.handleIntent(getIntent(), this);

        regToWx();
        getAuthToken();
    }

    private void regToWx() {

        api.handleIntent(getIntent(), this);
        boolean registered = api.registerApp(APP_ID);

        L.e(this, "registered: " + registered);

    }

    @Override
    protected void onNewIntent(Intent intent) {
        super.onNewIntent(intent);

        setIntent(intent);
        api.handleIntent(intent, this);
    }

    public void getAuthToken() {
        SendAuth.Req req = new SendAuth.Req();
        req.scope = "post_timeline";
        req.state = "none";

        boolean requestDone = api.sendReq(req);
        L.e(this, "request done: " + requestDone);

        SendAuth.Resp resp = new SendAuth.Resp();
        requestDone = api.sendResp(resp);
        L.e(this, "request done: " + requestDone);
    }

    @Override
    public void onReq(BaseReq baseReq) {
        L.e(this, "scope: " + ((SendAuth.Req) baseReq).scope);
    }

    @Override
    public void onResp(BaseResp baseResp) {
        L.e(this, "token: " + ((SendAuth.Resp) baseResp).token);
    }
}

Log cat输出:

Answer 1

onReq并将在JAVA反射中onResp调用WXEntryActivity.java

假设包名io.github.you

您应该创建一个名为 的目录wxapi，然后创建一个WXEntryActivity.java

你得到io.github.you.wxapi.WXEntryActivity.java

在AndroidManifest.xml

<activity
    android:name=".wxapi.WXEntryActivity"
    android:exported="true"
    android:label="@string/title_activity_wxentry"
    android:screenOrientation="portrait"
    android:theme="@android:style/Theme.NoDisplay" > 

在WXEntryActivity.java

public class WXEntryActivity implements IWXAPIEventHandler{

@Override
public void onReq(BaseReq arg0) {
    SendAuth.Resp r = (SendAuth.Resp)resp;
    String code = r.code;

}

@Override
public void onResp(BaseResp arg0) {
    // TODO Auto-generated method stub
    }
}

祝你好运
