问题描述
我的Retrofit应该会收到一个书签列表，并且在使用WAMP服务器时一切正常.当我将服务器更改为外部服务器时(没有其他更改，只是服务器的IP地址并检索了所有其他内容)，我遇到了一个错误:
My Retrofit should recieve a List of Bookmarks, and everything worked while I was using WAMP server. When I changed server to external (nothing else changed, just ip address of the server and retrieving of everything else works) I have an error:

System.out.println(email);

java.io.EOFException:第1行第1列的输入结束
java.io.EOFException: End of input at line 1 column 1
它表示解析某些内容时出现问题.希望可以解析一些文本，但是它具有文件结尾(EOF).
it indicates a problem with parsing something. It's expecting some text to parse but it got End of File (EOF).
那你说:
当我将服务器更改为外部服务器时(没有其他更改)
When I changed server to external (nothing else changed)
如果这以前可行，那么您的问题肯定不在代码上，而是在您要检索的数据上.您的新服务器正在拒绝您的请求或返回空白数据.尝试手动执行相同的请求(通过 postman 或其他一些api客户端)，看看响应是什么.它很可能会告诉您错误在哪里.
If this worked before, your problem is definitely not on your code and it is on the data you're retrieving. Your new server is either rejecting your requests or returning blank data. Try doing the same request manually (via postman or some other api client) and see what the response is. It'll very likely tell you where the error is.
