php - 获取“org.apache.http.conn.httphostconnectexception 连接到 http ://x. x.x.x :88/mobile. php 被拒绝

Question

我已经使用 xampp 设置了一个 MySql 服务器，我正在创建一个 Android 应用程序来连接到数据库。我可以使用 MYSQL Workbench 和 ODBC 连接器从异地进行连接，并且能够毫无错误地推/拉数据。当与模拟手机连接时，我在 DDMS 中收到“org.apache.http.conn.httphostconnectexception 连接到 http://x.x.x.x:88/mobile.php 被拒绝”。知道为什么会发生这种情况吗？？？

允许互联网未打开...现在已打开，刚刚经过验证、清理并重新启动，现在我收到“ClientProtocolException”。

public void getData() {
    String result = "";
    InputStream isr = null;
    try {
        HttpClient httpclient = new DefaultHttpClient();
        ///external ip address not local host or trying inside a local network
        HttpPost httpost = new HttpPost("http://x.x.x.x:88/mobile.php");
        HttpResponse response = httpclient.execute(httpost);
        HttpEntity entity = response.getEntity();
        isr = entity.getContent();
    } catch (Exception e) {
        Log.e("log.tag", "Error in http connection  " + e.toString());
        resultView.setText("Could not connect to Database");
    }
    try {
        BufferedReader reader = new BufferedReader(new InputStreamReader(
                isr, "iso=8859-1"), 8);
        StringBuilder sb = new StringBuilder();
        String line = null;
        while ((line = reader.readLine()) != null) {
            sb.append(line + "\n");
        }
        isr.close();

        result = sb.toString();
    } catch (Exception e) {
        Log.e("log.tag", "Error converting result  " + e.toString());
    }
    try {
        String s = "";
        JSONArray jArray = new JSONArray(result);
        for (int i = 0; i < jArray.length(); i++) {
            JSONObject json = jArray.getJSONObject(i);
            s = s + "User :" + json.getString("UserName");
        }
        resultView.setText(s);
    } catch (Exception e) {
        Log.e("log.tag", "Error Parsing Data " + e.toString());
    }

}

实现此功能的步骤:

1. 将 INTERNET 权限添加到您的 list 中
2. 确保没有防火墙或代理阻止服务器端
3. 在 httpPost 声明之后添加 httpPost.setHeader("Accept", "application/json");
