  --data 'This is expected to be sent back as part of response body.'

回应:

https://httpbin.org/

它将在请求中使用以下类型的任何数据进行回显:

https://httpbin.org/anything Returns most of the below. https://httpbin.org/ip Returns Origin IP. https://httpbin.org/user-agent Returns user-agent. https://httpbin.org/headers Returns header dict. https://httpbin.org/get Returns GET data. https://httpbin.org/post Returns POST data. https://httpbin.org/put Returns PUT data. https://httpbin.org/delete Returns DELETE data https://httpbin.org/gzip Returns gzip-encoded data. https://httpbin.org/status/:code Returns given HTTP Status code. https://httpbin.org/response-headers?key=val Returns given response headers. https://httpbin.org/redirect/:n 302 Redirects n times. https://httpbin.org/relative-redirect/:n 302 Relative redirects n times. https://httpbin.org/cookies Returns cookie data. https://httpbin.org/cookies/set/:name/:value Sets a simple cookie. https://httpbin.org/basic-auth/:user/:passwd Challenges HTTPBasic Auth. https://httpbin.org/hidden-basic-auth/:user/:passwd 404'd BasicAuth. https://httpbin.org/digest-auth/:qop/:user/:passwd Challenges HTTP Digest Auth. https://httpbin.org/stream/:n Streams n–100 lines. https://httpbin.org/delay/:n Delays responding for n–10 seconds.

创建选择一个免费的网络主机，并把以下代码

<h1>Request Headers</h1>
<?php
$headers = apache_request_headers();
     
foreach ($headers as $header => $value) {
    echo "<b>$header:</b> $value <br />\n";
}
?>

我不知道为什么这里所有的答案都让一个很简单的工作很辛苦!

当HTTP上有一个请求时，实际上客户端会发送一个HTTP_MESSAGE到服务器(阅读HTTP_MESSAGE是什么)，你可以用2个简单的步骤创建一个服务器:

安装netcat: 在许多基于unix的系统中，你已经安装了这个，如果你有windows只是谷歌它，安装过程真的很简单，你只需要一个nc.exe文件，然后你应该复制这个nc.exe文件的路径到你的path环境变量，并检查nc -h是否一切正常 创建一个监听localhost:12345的服务器: 只要在你的终端上输入nc -l -p 12345，一切就完成了!(在mac nc -l 12345 tnx Silvio Biasiol)

现在你有一个服务器在http://localhost:12345上监听，例如，如果你是一个js开发人员，你可以用axios发出post请求:

axios.post('http://localhost:12345', { firstName: 'Fred' })

或者制作自己的xhr，或者在HTML文件中制作表单并将其提交给服务器，例如:

<form action="http://localhost:12345" method="post">

或者使用curl或wget等进行请求。然后检查你的终端，一个原始的HTTP_MESSAGE应该出现在你的终端上，你可以开始你的快乐黑客;)

如果你需要或想要一个简单的HTTP服务器与以下:

是否可以在本地运行或在与公共Internet密封的网络中运行 有基本的认证吗 处理POST请求

我在PyPI上已有的出色的SimpleHTTPAuthServer之上构建了一个。这增加了POST请求的处理: https://github.com/arielampol/SimpleHTTPAuthServerWithPOST

否则，所有其他公开可用的选项都已经很好很健壮了。
