Question

之前，我的phpmyadmin中有数据库MySQL离线（我使用的是xampp）。我可以从我的Android设备或模拟器获取并发布（插入）请求。网址很简单，例如localhost / cek_user＆＃39;哦，我使用json将数据解析为php。

然后我决定将其设为在线，现在我必须将我的程序中的整个网址更改为＆＃39; http://kun-bfashion.com/cek_user＆＃39;问题出在这里。

我可以使用此代码获得用户名，密码等内容，我只需在我的课程中调用它：

public String sendGetRequest(String reqUrl){
    HttpClient httpClient;
    HttpGet httpGet = new HttpGet(serverUri+"/"+reqUrl);
    InputStream is = null;
    StringBuilder stringBuilder = new StringBuilder();
    try {
        HttpParams params = new BasicHttpParams();
        HttpConnectionParams.setConnectionTimeout(params, 3000);
        HttpConnectionParams.setSoTimeout(params, 3000);
        httpClient = new DefaultHttpClient(params);
        Log.d(TAG, "executing...");
        HttpResponse httpResponse = httpClient.execute(httpGet);
        StatusLine status = httpResponse.getStatusLine();
        if(status.getStatusCode() == HttpStatus.SC_OK && httpResponse != null){
            /* mengambil response string dari server     */
            HttpEntity httpEntity = httpResponse.getEntity();
            is = httpEntity.getContent();
            BufferedReader reader = new BufferedReader(new InputStreamReader(is));
            String line = null;
            while((line = reader.readLine()) != null){
                stringBuilder.append(line+"\n");
            }
            is.close();
        }
    } catch (Exception e) {
        //Log.d(TAG, e.getMessage());
    }
    return stringBuilder.toString();
}

serverUri和reqUrl是我的网站，我只是将其设置为静态＆＃39; http://kun-bfashion.com，而reqURL就像是＆＃39; cek_user＆＃39;。我使用该代码进行登录，从服务器获取数据等等。

但是当我想发布像注册用户一样，它显示吐司＆＃34;保存数据问题＆＃34;，我使用此代码发布到网络服务

public int sendPostRequest(User user, String url){
    int replyCode = 99;
    HttpClient httpClient;
    HttpPost post = new HttpPost(this.serverUri+"/"+url);
    List<NameValuePair> value = new ArrayList<NameValuePair>();
    /* menambahkan parameter ke dalam request */
    value.add(new BasicNameValuePair("id_user", user.getId_User().toString()));
    value.add(new BasicNameValuePair("username", user.getUsername()));
    value.add(new BasicNameValuePair("nama_user", user.getNamaUser()));
    value.add(new BasicNameValuePair("email_user", user.getEmailUser()));
    value.add(new BasicNameValuePair("password_user",user.getPasswordUser()));

    try {
        HttpParams params = new BasicHttpParams();
        HttpConnectionParams.setConnectionTimeout(params, 3000);
        HttpConnectionParams.setSoTimeout(params, 3000);
        httpClient = new DefaultHttpClient(params);
        post.setEntity(new UrlEncodedFormEntity(value));
        Log.d(TAG, "executing post...");
        HttpResponse httpResponse = httpClient.execute(post);
        StatusLine status = httpResponse.getStatusLine();
        if(status.getStatusCode() == HttpStatus.SC_OK){
            Log.d(TAG, "submitted sucessfully...");
            replyCode = status.getStatusCode();
        }
    } catch (IOException e) {
        Log.d(TAG, e.getMessage());
    }
    return replyCode;
}

错误显示Toast＆＃34;保存数据问题＆＃34;，但在我的离线数据库（localhost）之前，我可以插入帖子并获得没有错误。

当我按下注册按钮时，这是我的LogCat：

很抱歉很长的帖子，但我不知道如何解释我的问题-_-。谢谢你的阅读。

问题是我可以从服务器获取，但我无法发布

Answer 1

这可能是服务器问题，但根据This post，可能会通过更改代码以将HttpParams应用于HttpPost而不是DefaultHttpClient来解决问题：

    HttpParams params = new BasicHttpParams();
    HttpConnectionParams.setConnectionTimeout(params, 3000);
    HttpConnectionParams.setSoTimeout(params, 3000);
    //httpClient = new DefaultHttpClient(params);
    httpClient = new DefaultHttpClient(); //use default constructor instead
    post.setParams(params); //add call to setParams on HttpPost
    post.setEntity(new UrlEncodedFormEntity(value));

编辑：使用日志记录验证URL：

HttpPost post = new HttpPost(this.serverUri+"/"+url);
Log.d(TAG, "post url: " + this.serverUri+"/"+url );

在浏览器中测试网址，看看是否有任何json响应。
