Question

好的我正在尝试这个电话：

    ArrayList<NameValuePair> httpParams;

    httpParams = new ArrayList<NameValuePair>();
    httpParams.add(new BasicNameValuePair("name", name));
    httpParams.add(new BasicNameValuePair("username", username));
    httpParams.add(new BasicNameValuePair("password", password));
    httpParams.add(new BasicNameValuePair("email", email));
    httpParams.add(new BasicNameValuePair("gender", gender));

    try {
        SERVICE_URL = new URL("http://idea-app.net/android/com/ProjectCaruso/Idea/SaveUser.php");

    } catch (MalformedURLException e) {
        Log.i(Utils.TAG, "Login Async: MalformedURLException: " + e.toString());
        e.printStackTrace();
    }


    String response = doUrlPost(SERVICE_URL, httpParams);

以下是它所调用的代码：

public String doUrlPost(URL url, ArrayList<NameValuePair> httpParams) {

    if (url != null) {
        String response = "";

        try {
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            conn.setReadTimeout(10000);
            conn.setConnectTimeout(15000);
            conn.setRequestMethod("POST");
            conn.setDoInput(true);
            conn.setDoOutput(true);

            OutputStream os = conn.getOutputStream();
            BufferedWriter writer = new BufferedWriter(
                    new OutputStreamWriter(os, "UTF-8"));
            writer.write(getQuery(httpParams));
            writer.close();
            os.close();

            conn.connect();

            //start listening to the stream
            Scanner inStream = new Scanner(conn.getInputStream());

            //process the stream and store it in StringBuilder
            while(inStream.hasNextLine())
            response+=(inStream.nextLine());

        } catch (ProtocolException e) {
            Log.i(Utils.TAG, "Login Async: ProtocolException: " + e.toString());
        }
         catch (IOException e) {
             Log.i(Utils.TAG, "Login Async: IOException: " + e.toString());
        }

        return response;
    } else {
        return null;
    }

}

public String getQuery(List<NameValuePair> params) throws UnsupportedEncodingException {
    StringBuilder result = new StringBuilder();
    boolean first = true;

    for (NameValuePair pair : params)
    {
        if (pair.getValue() == null) {
            Log.i(Utils.TAG, "Push Data: Null value pair for: " + pair.getName());
        } else {

            if (first)
                first = false;
            else
                result.append("&");
                result.append(URLEncoder.encode(pair.getName(), "UTF-8"));
                result.append("=");
                result.append(URLEncoder.encode(pair.getValue(), "UTF-8"));
                }
    }

    return result.toString();
}

这是错误：

请参阅LogCat：

java.io.FileNotFoundException: http://idea-app.net/android/com/ProjectCaruso/Idea/SaveUser.php

这个网址真的存在吗？ http://idea-app.net/android/com/ProjectCaruso/Idea/SaveUser.php

Android URL IOException
