android - 没有得到响应 response = httpclient.execute(request);

Question

public class HTTPPoster {
    public static HttpResponse doPost(String url, JSONObject c) throws ClientProtocolException, IOException 
    {

        HttpClient httpclient = new DefaultHttpClient();
        HttpPost request = new HttpPost(url);

        HttpEntity entity;
        StringEntity s = new StringEntity(c.toString());
        s.setContentEncoding((Header) new BasicHeader(HTTP.DEFAULT_CONTENT_CHARSET, "application/json"));
        entity = s;
        request.setEntity(entity);

        HttpResponse response;

        response = httpclient.execute(request);

        return response;
    }

}

这是代码，但在 response = http.client.execute(request) 上没有得到响应。我找不到原因。

您应该异步调用该方法。然后它将使用相同的代码。将这两行代码添加到你的项目中

StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
        StrictMode.setThreadPolicy(policy);

和将最低 sdk 版本设置为 9
