打印HttpParams / HttpUriRequest的内容？ [英] Print contents of HttpParams / HttpUriRequest?

问题描述

我有一个 HttpUriRequest 实例，有没有办法打印它包含的所有参数？例如，我几乎可以得到它们：

I have an HttpUriRequest instance, is there a way to print all the parameters it contains? For example, I can almost get them like:

HttpUriRequest req = ...;
HttpParams params = req.getParams();
for (int i = 0; i < params.size(); i++) { // ?
    println(params.getParam(i); // ?
}

有没有办法做到这一点？

Is there a way to do this?

谢谢

推荐答案

是你在寻找HTTP参数或URI参数吗？

Are you looking for the HTTP parameters or the URI parameters?

HTTP参数类似于用户代理，套接字缓冲区大小，协议版本等。

The HTTP parameters are things like user-agent, socket buffer size, protocol version, etc.

URI参数是作为请求的一部分传递的客户端值，例如

The URI parameters are the client values that get passed as part of the request, e.g.

?param1=value1&param2=value2

如果您正在寻找URI参数，请尝试像这样：

If you're looking for the URI parameters, try something like this:

List<String> uriParams = Arrays.asList(request.getURI().getQuery().split("&"));

但是如果你确实想要原始的HTTP参数，那就复杂一点了因为并非HttpParams的所有实现都支持 getNames（）。你必须做这样的事情：

But if you do want the raw HTTP params, it's a little more complicated because not all implementations of HttpParams supports getNames(). You'd have to do something like this:

HttpParamsNames params = (HttpParamsNames)request.getParams();
Set<String> names;

if (params instanceof ClientParamsStack) {
    names = new HashSet<>();

    // Sorted by priority, see ClientParamsStack
    ClientParamsStack cps = (ClientParamsStack)params;
    if (cps.getApplicationParams() != null) {
        names.addAll(((HttpParamsNames)cps.getApplicationParams()).getNames());
    }
    if (cps.getClientParams() != null) {
        names.addAll(((HttpParamsNames)cps.getClientParams()).getNames());
    }
    if (cps.getRequestParams() != null) {
        names.addAll(((HttpParamsNames)cps.getRequestParams()).getNames());
    }
    if (cps.getOverrideParams() != null) {
        names.addAll(((HttpParamsNames)cps.getOverrideParams()).getNames());
    }
} else {
    names = params.getNames();
}

for (String name : names) {
    System.out.println(name + ": " + request.getParams().getParameter(name));
}
