安卓Volley连接错误：java.io.InterruptedIOException

Question

我有以下代码，使用Volley向Web服务发出请求：

RequestQueue requestQueue =  Volley.newRequestQueue(getActivity(),new OkHttpStack());
GsonRequest<myData> request = new GsonRequest<myData>(Method.POST,Config.MYPOSTLINK, myData.class, getSuccessListener, getErrorListener);
request.setParams("Token", token);        
requestQueue.add(request);

我已经按照这个样子实现了OkHttpStack.java：

public class OkHttpStack extends HurlStack {
    private final OkHttpClient client;

    public OkHttpStack() {
        this(new OkHttpClient());
    }

    public OkHttpStack(OkHttpClient client) {
        if (client == null) {
            throw new NullPointerException("Client must not be null.");
        }
        this.client = client;
    }

    @Override protected HttpURLConnection createConnection(URL url) throws IOException {
        return new OkUrlFactory(client).open(url);
    }
}

有时我会遇到以下错误：

如何克服这个问题？如果我遇到此错误，有什么重新请求的方法吗？

Answer 1

在这个请求之前，我正在处理另一个请求，但那个请求出现了错误。我将上面的requestQueue代码也实现到了那个请求中，现在没有错误了。我的代码很好用。

Answer 2

尝试按照以下方式使用此代码：

import com.android.volley.toolbox.HurlStack;
import com.squareup.okhttp.OkHttpClient;
import com.squareup.okhttp.OkUrlFactory;

public class OkHttpStack extends HurlStack {
    private final OkUrlFactory mFactory;

    public OkHttpStack() {
        this(new OkHttpClient());
    }

    public OkHttpStack(OkHttpClient client) {
        if (client == null) {
            throw new NullPointerException("Client must not be null.");
        }
        mFactory = new OkUrlFactory(client);
    }
}

你可以参考我的代码来实现OkHttpStack *更新：

当你自定义请求队列代码时，可能需要检查一下。你是否在代码中添加了requestQueue.start()？如果是，并且它会显示interruptedioexception。
