Android的HTTP POST请求错误 - 套接字失败EACCES（权限被拒绝） [英] Android HTTP POST request error - socket failed EACCES (Permission denied)

问题描述

我想要一个POST请求从一个Android应用程序在 Eclipse的发到我的本地主机，但我收到此错误：

  

套接字失败EACCES（权限被拒绝）。

我这样做是通过apache.commons库。我试图通过HttpClient的前连接，但有一个类似的错误：

  

连接到为myhost 拒绝。

下面是code：

 公共无效的onClick（视图v）{
        登录=（EditText上）findViewById（R.id.entry_login）;
        。用户登陆= login.getText（）的toString（）;

        PWD =（EditText上）findViewById（R.id.entry_password）;
        。userPwd = pwd.getText（）的toString（）;

        的BufferedReader BR = NULL;

        HttpClient的HttpClient的=新的HttpClient（）;

        的PostMethod方法=新的PostMethod（http://127.0.0.1/testPost.php）;
        method.addParameter（姓名，亚瑟）;

        的System.out.println（登录：+用户登陆）;

        尝试 {
            httpclient.executeMethod（法）;

            int返回code = httpclient.executeMethod（法）;

            如果（返程code == HttpStatus.SC_NOT_IMPLEMENTED）{
                通信System.err.println（POST方法不受此URI执行）;

                //仍然消耗响应体
                method.getResponseBodyAsString（）;
            }
            其他 {
                BR =新的BufferedReader（新的InputStreamReader（method.getResponseBodyAsStream（）））;
                字符串的readLine;
                而（（（的readLine = br.readLine（））！= NULL））{
                    通信System.err.println（的readLine）;
                }
            }

            / *列表与LT;的NameValuePair＆GT; namevaluepairs中=新的ArrayList＆LT;的NameValuePair＆GT;（2）;
                nameValuePairs.add（新BasicNameValuePair（姓名，亚瑟））;
                nameValuePairs.add（新BasicNameValuePair（OP_ID，10001））;
                nameValuePairs.add（新BasicNameValuePair（IP_ADDRESS，127.0.0.1））;
                nameValuePairs.add（新BasicNameValuePair（栏= field100，用户登陆+＆放大器; field101 =+ userPwd））;
                nameValuePairs.add（新BasicNameValuePair（REQ_TYPE =，26））;
            * /

            的System.out.println（HTTP连接做得很好！）;
            // response.getStatusLine（）;

        }
        赶上（例外五）{
            的System.out.println（e.getMessage（））;
        }
        最后 {
            method.releaseConnection（）;
            如果（BR！= NULL）
                尝试 {
                    br.close（）;

你有INTERNET权限您的清单？

检查的Andr​​oidManifest.xml 的followinf行

 ＆LT;使用-权限的Andr​​oid：名称=android.permission.INTERNET对/＆GT;
 

I'm trying to send a POST request to my localhost from an Android app under Eclipse, but I am receiving this error:

socket failed EACCES (Permission denied).

I'm doing this through the apache.commons library. I've tried to connect via HttpClient before, but there was a similar error:

Connect to myhost refused.

Here is the code:

    public void onClick(View v) {
        login = (EditText) findViewById(R.id.entry_login);
        userLogin = login.getText().toString();

        pwd = (EditText) findViewById(R.id.entry_password);
        userPwd = pwd.getText().toString();

        BufferedReader br = null;

        HttpClient httpclient = new HttpClient();

        PostMethod method = new PostMethod("http://127.0.0.1/testPost.php");
        method.addParameter("name", "Arthur");

        System.out.println("Login: " + userLogin);

        try {
            httpclient.executeMethod(method);

            int returnCode = httpclient.executeMethod(method);

            if (returnCode == HttpStatus.SC_NOT_IMPLEMENTED) {
                System.err.println("The Post method is not implemented by this URI");

                // Still consume the response body
                method.getResponseBodyAsString();
            }
            else {
                br = new BufferedReader(new InputStreamReader(method.getResponseBodyAsStream()));
                String readLine;
                while (((readLine = br.readLine()) != null)) {
                    System.err.println(readLine);
                }
            }

            /* List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
                nameValuePairs.add(new BasicNameValuePair("name", "Arthur"));
                nameValuePairs.add(new BasicNameValuePair("OP_ID", "10001"));
                nameValuePairs.add(new BasicNameValuePair("IP_ADDRESS", "127.0.0.1"));
                nameValuePairs.add(new BasicNameValuePair("FIELDS=field100", userLogin + "&field101=" + userPwd));
                nameValuePairs.add(new BasicNameValuePair("REQ_TYPE=", "26"));
            */

            System.out.println("http connection done well!");
            // response.getStatusLine();

        }
        catch (Exception e) {
            System.out.println(e.getMessage());
        }
        finally {
            method.releaseConnection();
            if (br != null)
                try {
                    br.close();
                }
                catch (Exception fe) {

                }
        }
    }
});
