使用 JSON 字符串解析 URL 时捕获 IllegalArgumentException [英] IllegalArgumentException caught when parsing URL with JSON String
本文介绍了使用 JSON 字符串解析 URL 时捕获 IllegalArgumentException的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我需要用 JSON 数据制定一个 url，看起来像
I need to formulate a url with JSON data that will look something like
http://someurl.com/passfail?parameter={"data1":"123456789","data2":"123456789"}，我需要使用 JBoss 的 ClientResponse 传递它以获得响应状态.我首先尝试在
http://someurl.com/passfail?parameter={"data1":"123456789","data2":"123456789"}, and I will need to pass it using JBoss's ClientResponse to get a response status. I first tried passing in the literal String data in
ClientRequest clientrequest = new ClientRequest("http://someurl.com/passfail?parameter={\"data1\":\"123456789\",\"data2\":\"123456789\"});// assuming the "\" is formulated correctly
但它给出了一个例外.因此，我也尝试使用 URL url = new URL(the url) 但效果不佳.
but it gives an exception. Thus I also tried using URL url = new URL(the url) but it doesn't work as well.
我在尝试时遇到了以下异常，感觉很卡住，希望有人能提供帮助.
I have the following exception caught trying and am feeling pretty stucked and am hoping if anyone could help.

推荐答案
问题是您在 URI 字符串中传递了非法字符:Java - 将字符串转换为有效的 URI 对象
The problem is that you're passing illegal characters in your URI string:Java - Convert String to valid URI object
http://someurl.com/passfail?parameter="data1":"123456789","data2":"123456789"}>
您需要转义"URI 中的违规字符.
You need to "escape" the offending characters in your URI.
这里有一些替代方案:
http://docs.oracle.com/javase/6/docs/api/java/net/URI.html
最后但并非最不重要的:
and, last but not least:
PS:网址中的>"怎么样?
PS: what about that ">" in your URL?
