BasicNetwork.performRequest：意外的响应code 500，Android的登记制度 [英] BasicNetwork.performRequest: Unexpected response code 500, Android Registration System
问题描述
最近，我开始在我的Android应用程序的工作，我需要一个登录名和登记制度。我发现androidhive.info的教程，但我不断地得到错误。我使用的是凌空库发送HTTP请求，并在LogCat中的错误与该库。我用我的DigitalOcean服务器的公网IP地址，我想是因为在本教程中，他们存储在本地主机的PHP脚本它可能有一些做这一点。这是我用于注册用户的android活动：
I recently started working on my Android app and I needed a login and registration system. I found a tutorial on androidhive.info but I constantly get errors. I'm using a volley library for sending HTTP requests and the error in LogCat is related to that library. I used a public IP address of my server on DigitalOcean and I think it might have something to do with that because in the tutorial they store the php scripts on localhost. This is my android activity used for registering users:

在我的课堂我AppConfig中存储的路径位置，在PHP脚本（公网IP）
In my class AppConfig I stored the path to location where the php scripts are (Public IP)
package foi.hr.air.asocijacije.main;
public class AppConfig {
public static String URL_LOGIN = "http://95.85.57.105/android_login_api/";
public static String URL_REGISTER = "http://95.85.57.105/android_login_api/";
}
这是我收到的LogCat中的错误日志
And this is the error log that I'm getting in LogCat
04-29 11:35:18.440: E/Volley(1742): [180] BasicNetwork.performRequest: Unexpected response code 500 for http://95.85.57.105/android_login_api/
04-29 11:35:18.916: E/RegisterActivity(1742): Registration error: null
我希望你能帮助我得到这个东西吧，我尝试使用Mozilla的插件的Htt prequester POST方法来尝试将数据存储在我的网上MySQL数据库只是要确保PHP脚本工作正常，但我不知道我应该在JSON格式发送什么样的内容。如果需要的话，我将发布更多的数据，所以你可以明白问题出在哪里。
I hope that you can help me get this thing right, I tried using POST method on Mozilla plugin HttpRequester to try to store data in my online MySQL database just to be sure that the php scripts are working fine, but I don't know what content should I send in JSON format. If needed I will post additional data so you could understand where the problem is.
推荐答案
这难道不是应该是
public static String URL_LOGIN = "http://95.85.57.105/android_login_api/login.php";
public static String URL_REGISTER = "http://95.85.57.105/android_login_api/register.php";
林不知道抛给你的错误是正好404或500，但还是给它一个尝试。
Im not sure whether the error thrown to you is exactly 404 or 500 , But still Give it a try.
