使用HttpURLConnection的Android设备上的PHP HTTP POST

问题:

所以问题是，这不会发布到goDaddy托管的在线数据库中。所以我的问题是为什么，我如何修复它，让它发布到它

问题: php页面没有收到传递给它的名称-值对

编辑：

修改了建议使用HttpURLConnection的代码。。。 我已经把问题缩小到不检索fbid

正如你所说，我在这里做了很多家庭作业。。。这是我在postthread类中设置的日志，这是我完成post的类：

07-02 16:41:45.108: I/PROJECTCARUSO(12308): response: {"posts":[null]}

HttpPostThread：

public class HttpPostThread extends Thread {
    public static final int FAILURE = 0;
    public static final int SUCCESS = 1;


    private URL url;
    ArrayList<NameValuePair> pairs;

    public HttpPostThread(URL sERVICE_URL, ArrayList<NameValuePair> pairs, final Handler handler)
    {
        Log.i("PROJECTCARUSO", "Posting to URL: " + sERVICE_URL);
        this.url =sERVICE_URL;
        this.pairs = pairs;
        if(pairs==null){
            Log.i("PROJECTCARUSO", "URL parms were null");
            this.pairs = new ArrayList<NameValuePair>();
        }
    }

    @Override
    public void run()
    {
        try {
            HttpURLConnection conn;
            String param="";

            for (NameValuePair nvp : pairs) {
                //you need to encode ONLY the values of the parameters
                if (param == "") {
                    param=nvp.getName() + "=" + URLEncoder.encode(nvp.getValue(),"UTF-8");
                } else {
                    param+= "&" + nvp.getName() + "=" + URLEncoder.encode(nvp.getValue(),"UTF-8");
                }
            }

            Log.i("PROJECTCARUSO", "param: " + param.toString());
            // Create connection
            conn=(HttpURLConnection)url.openConnection();
            //set the output to true, indicating you are outputting(uploading) POST data
            conn.setDoOutput(true);
            //once you set the output to true, you don't really need to set the request method to post, but I'm doing it anyway
            conn.setRequestMethod("POST");

            //Android documentation suggested that you set the length of the data you are sending to the server, BUT
            // do NOT specify this length in the header by using conn.setRequestProperty("Content-Length", length);
            //use this instead.
            conn.setFixedLengthStreamingMode(param.getBytes().length);
            conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
            //send the POST out
            PrintWriter out = new PrintWriter(conn.getOutputStream());
            out.print(param);
            out.close();

            //build the string to store the response text from the server
            String response= "";

            //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());

            Log.i("PROJECTCARUSO","response: " + response);
        }
        //catch some error
        catch(MalformedURLException ex){  
            Log.i("PROJECTCARUSO", ex.toString());

        }
        // and some more
        catch(IOException ex){

            Log.i("PROJECTCARUSO", ex.toString());

        }

    }

    public static boolean isNumeric(String str)  
    {  
      try  
      {  
        double d = Double.parseDouble(str);  
      }  
      catch(NumberFormatException nfe)  
      {  
        return false;  
      }  
      return true;  
    }
}

编辑：

我甚至尝试了java，如下所示：

public void run() {
    try {
    HttpURLConnection conn = (HttpURLConnection) url.openConnection();
    conn.setReadTimeout(10000);
    conn.setConnectTimeout(15000);

        conn.setRequestMethod("POST");

    conn.setDoInput(true);
    conn.setDoOutput(true);

    List<NameValuePair> params = new ArrayList<NameValuePair>();
    for (NameValuePair nvp : pairs) {
    //you need to encode ONLY the values of the parameters
        params.add(new BasicNameValuePair(nvp.getName(), nvp.getValue()));
        Log.i("PROJECTCARUSO", "NVP: " + nvp.getName() + " - " + nvp.getValue());
    }


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

    conn.connect();

    //build the string to store the response text from the server
    String response= "";

    //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());

    Log.i("PROJECTCARUSO","response: " + response);

    } catch (ProtocolException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

     catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
    }

假设您使用apache HttpClient作为默认客户端

您需要有关WIRE和Header的更多数据。演示如何打开这些记录器。阅读有关日志记录的apache文档

下面是您将看到的示例（您将确切地知道客户端和服务器之间发生了什么）

完全登录apache HttpClient：

D/ch.boye.httpclientandroidlib.wire（1175）：您必须使用
$\u POST
而不是
$\u GET
无处不在。
为什么要在变量字符串值周围添加单引号？对于insert语句…在测试它时，我发现，如果它周围没有引号，则在执行insert时，它会失败。因此，它最终会在用户中查找line
insert（_id，name，…）值（'0121'，'Jason'，…）
当我在浏览器中打开页面并添加所有paramaters@Jonast92你的评论没有建设性。但是，如果你确实有一个建议要提，尽管是离题的，我很乐意听到。这是否表示“成功发送请求”？您也不会检查响应是否为200，等等。因此，请验证这一点。此外，将此问题分解为特定的android和php问题。它们不相关。它确实显示“成功发送请求”.我没有打断它，因为它似乎都在android端，但我可能不正确。至于检查响应，您是指插入的sql响应还是指android端的响应？说得太快了…godaddys端有apache日志…让我看看这个，看看上面的编辑。我看到了这个解释：我的错误..看起来不像服务器端问题使用curl从cli测试php。在开始使用android客户端之前，你应该确定你的服务器在响应体中发布了良好的json。使用curl的cli？请解释？这是我能给出的最长答案：）
