Get the Raw Request String from HttpServletRequest
提问by Jaime Garcia
Is it possible to get the raw HTTP Request from the HttpServletRequest object? I want to see the raw request as a String if at all possible.
是否可以从 HttpServletRequest 对象获取原始 HTTP 请求？如果可能的话，我想将原始请求视为字符串。
I need to get the full text of the request, in this case it's a POST request, so the URL doesn't help. It's also part of a multi-part form, so I can't just call the "getParameterNames()" or "getParameterValues()".
我需要获取请求的全文，在这种情况下它是一个 POST 请求，所以 URL 没有帮助。它也是多部分表单的一部分，所以我不能只调用“getParameterNames()”或“getParameterValues()”。
Thank you,
谢谢，

Sounds like you need a servlet filter. There is no standard way to handle multipart/form-data, so you'll have to take care to cache this data appropriately when wrapping the HttpServletRequest.
听起来您需要一个servlet 过滤器。没有处理 的标准方法multipart/form-data，因此在包装 HttpServletRequest时，您必须注意适当地缓存此数据。

or if you can write some interceptor to convert the parameter names and values to string format object and set it in request context, or filter is a good idea too.
或者如果您可以编写一些拦截器将参数名称和值转换为字符串格式对象并将其设置在请求上下文中，或者过滤器也是一个好主意。

Well, it sounds like you are doing some sort of troubleshooting. Why not just drop the multi-part form component while you are looking at the raw form data. You can use the following JSP snippet to construct the form data.
嗯，听起来你正在做某种故障排除。为什么不在查看原始表单数据时删除多部分表单组件。您可以使用以下 JSP 片段来构造表单数据。
<%
Enumeration en = request.getParameterNames();
String str = "";
while(en.hasMoreElements()){
String paramName = (String)en.nextElement();
String paramValue = request.getParameter(paramName);
str = str + "&" + paramName + "=" + URLEncoder.encode(paramValue);
}
if (str.length()>0)
str = str.substring(1);
%>

You can read the raw HTTP request by doing:
您可以通过执行以下操作读取原始 HTTP 请求：
ServletInputStream in = request.getInputStream();
and then use the regular readmethods of the InputStream.
然后使用readInputStream的常规方法。
Hope that helps.
希望有帮助。

If you want to get the whole request to a String you can do it with one line of code using the apache IOUtils library.
如果您想将整个请求发送到一个字符串，您可以使用 apache IOUtils 库通过一行代码来完成。
String myString = org.apache.commons.io.IOUtils.toString(request.getInputStream());
