无法在Java/Apache HttpClient中使用垂直/管道栏处理URL

Question

如果我想要处理此网址,例如:

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

Java/Apache不会让我,因为它说垂直条("|")是非法的.

用双斜线转义它也不起作用:

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

^不起作用.

有任何建议如何使这项工作？

Answer 1

尝试 URLEncoder.encode()

注意:你应该编码后面action=没有的字符串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

Answer 2

您必须|在URL中编码为%7C.

考虑使用HttpClient URIBuilder来处理逃逸,例如:

final URIBuilder builder = new URIBuilder();
builder.setScheme("http")
    .setHost("testurl.com")
    .setPath("/lists/lprocess")
    .addParameter("action", "LoadList|401814|1");
final URI uri = builder.build();
final HttpPost post = new HttpPost(uri);
