无法在 Java/Apache HttpClient 中使用垂直/管道栏处理 url [英] Cannot process url with vertical/pipe bar in Java/Apache HttpClient

问题描述

如果我想处理这个网址，例如:

If I want to process this url for example:

post = new HttpPost("http://testurl.com/lists/lprocess?action=LoadList|401814|1");

Java/Apache 不允许我，因为它说竖线(|")是非法的.

Java/Apache won't let me because it says that the vertical bar ("|") is illegal.

用双斜线转义它也不起作用:

escaping it with double slashes doesn't work as well:

post = new HttpPost("http://testurl.com/lists/lprocess?action=LoadList\\|401814\\|1");

^ 那也行不通.

对如何使这项工作有任何建议?

Any suggestions how to make this work?

推荐答案

try with URLEncoder.encode()

注意:你应该对action=之后的字符串进行编码，而不是完整的URL

Note: you should encode string which is after action= not complete URL

post = new HttpPost("http://testurl.com/lists/lprocess?action="+URLEncoder.encode("LoadList|401814|1","UTF-8"));

参考 http://docs.oracle.com/javase/7/docs/api/java/net/URLEncoder.html
