我曾经看到过类似的有关这个问题的文章, 但其中都与使用视觉演播室开发服务器 用于ASP.NET无关。

我收到以下错误 。

<% 1> 您主机 的软件中止了已建立的连接 。

我执行以下代码:

String employeesJson = client.downloadString("http://localhost:60000/Api/Employee/GetEmployees.aspx");

当我在一个普通的网络浏览器(21世纪或10世纪互联网探索器)中运行这个时,它运行很好。我得到了我想要的JSON结果。

我的 WebClient 类(在变量“client ”下)被使用,定义如下。

public class WebClient {

    private HttpClient httpClient;

    public WebClient() {

        httpClient = new DefaultHttpClient();

    }

    public String downloadString(String url) throws IOException {

        HttpGet get = new HttpGet(url);

        try {

            HttpResponse response = httpClient.execute(get); //this is where the error occurs.
            HttpEntity entity = response.getEntity();
            if(entity != null) {

                InputStream stream = entity.getContent();
                InputStreamReader streamReader = new InputStreamReader(stream);

                BufferedReader bufferedReader = new BufferedReader(streamReader);
                StringBuilder builder = new StringBuilder();

                String line = null;
                try {
                    while ((line = bufferedReader.readLine()) != null) {
                        builder.append(line + "
");
                    }
                } catch (IOException e) {
                    e.printStackTrace();
                } finally {
                    try {
                        stream.close();
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                }

                return builder.toString();

            }

        //catch all the types of exceptions this method can throw. catching "Exception" is considered bad.
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        }

        return null;

    }

}

我的机器人Manifest.xml文件看起来是这样的:
