英文:
How do i get parameter value from url as string
问题
我有一个请求，其响应显示在以下URL中。我需要从URL中提取user_token的值，并传递给后续的请求。
响应URL：http://example.com?user_token=0c1c59bc-3aaa-40f1-b978-7172de09a27f&m_id=9999&code=200&is_register=false&M=SUCCESS
我想从中提取user_token，并希望在后续请求中传递它。需要使用Java代码的解决方案，而不是JavaScript。
英文:
I have one request which response is displayed as url below. I need to extract user_token value from url and pass to subsequent request.
response url: http://example.com?user_token=0c1c59bc-3aaa-40f1-b978-7172de09a27f&m_id=9999&code=200&is_register=false&M=SUCCESS
i want to extract user_token from it and want to pass it to subsequent request, need solution in java code not java script.

你可以这样做：
String getTokenId(String url) {String[] splitUrl = url.split("user_token=");String tokenId = "";if (splitUrl.length > 1) {for (int i = 0; i < splitUrl[1].length(); i++) {if (splitUrl[1].charAt(i) == '&') {tokenId = splitUrl[1].substring(0, i);break;}}}return tokenId;}
但如果你知道令牌的确切长度，也可以进行搜索。
英文:
You can do this:
String getTokenId(String url){
String[] splitUrl = url.split("user_token=");String tokenId = "";if(splitUrl.length >1){for(int i =0; i < splitUrl[1].length(); i++){if(splitUrl[1].charAt(i) == '&'){tokenId = splitUrl[1].substring(0,i);break;}}}return tokenId;}
But if you know the exact length of the token, it could be a search.

也许你需要的是 request.getParameter("user_token")。你可以在Servlet中这样做，例如：
英文:
Maybe what you need is request.getParameter("user_token"). You can do this in servlet for example
