Question

我正在尝试做一个简单的HttpGet但它甚至没有进入App空间，因为Fiddler没有出现。

private final static String EMPLOYEE_SERVICE_URI = "http://localhost:82/EmployeeService_deploy/EmployeeInfo.svc/GetEmployee/?key=";  

        DefaultHttpClient client = new DefaultHttpClient();
        HttpGet request = new HttpGet(EMPLOYEE_SERVICE_URI + "11");

        request.setHeader("Accept", "application/json");
        request.setHeader("Content-type", "application/json");

        //get the response
        try
        {
            HttpResponse response = client.execute(request);

我有一种感觉，这可能是因为我的工作有防火墙而且这是在端口82上。我曾经想过，因为它可能允许它，但可能没有。在清单中，我有以下权限

＆LT;

uses-permission android:name="android.permission.INTERNET" />       
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

有没有人有任何建议，这可能是什么以及我如何解决它？我无法访问我的工作代理设置，因此如果这是问题，我无法指定代理。有什么方法可以通过端口80路由它吗？

使用异步任务来使用HTTP调用。

private class HttpCalling extends AsyncTask<String, String, String> {

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
    }

    @Override
    protected String doInBackground(String... params) {
                    String resp;
        //HTTP calls here
        return resp;
    }

    @Override
    protected void onPostExecute(String result) {
        super.onPostExecute(result);

    }
}

您的应用是在模拟器上还是在设备上运行？哪里跑小提琴？如果你想使用127.0.0.1那么它们都应该在同一设备上的一个emulatof或两者上。
