打印 HttpParams / HttpUriRequest 的内容？

发布于 2024-10-19 18:04:23 字数 460 浏览 3 评论 0原文

我有一个 HttpUriRequest实例，有没有办法打印它包含的所有参数？例如，我几乎可以得到他们这样的信息：

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？

谢谢

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); // ?
}

Is there a way to do this?

Thanks

您可以简单地迭代所有标头字段。

HttpUriRequest req = ...;
.......
Header[] headerFields = request.getAllHeaders();
for(int e = 0; e<header.length; e++){                                    
    System.out.println(headerFields[e].getName() + ": " + headerFields[e].getValue());
}

建议的方法 params.toString() 不起作用。

You can simply iterate over all Header fields.

HttpUriRequest req = ...;
.......
Header[] headerFields = request.getAllHeaders();
for(int e = 0; e<header.length; e++){                                    
    System.out.println(headerFields[e].getName() + ": " + headerFields[e].getValue());
}

The suggested method params.toString() does not work.

您是在寻找 HTTP 参数还是 URI 参数？

HTTP 参数是用户代理、套接字缓冲区大小、协议版本等。URI

参数是作为请求一部分传递的客户端值，例如，

?param1=value1¶m2=value2

如果您正在查找 URI 参数，请尝试这样的操作：

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

但是如果您确实想要原始 HTTP 参数，那就有点复杂了，因为并非所有 HttpParams 的实现都支持 getNames()。你必须做这样的事情：

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));
}

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

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

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

?param1=value1¶m2=value2

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

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

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));
}
