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";
}
?>

如果你想要一个本地测试服务器接受任何URL并将请求转储到控制台，你可以使用node:

const http = require("http");

const hostname = "0.0.0.0";
const port = 3000;

const server = http.createServer((req, res) => {
  console.log(`\n${req.method} ${req.url}`);
  console.log(req.headers);

  req.on("data", function(chunk) {
    console.log("BODY: " + chunk);
  });

  res.statusCode = 200;
  res.setHeader("Content-Type", "text/plain");
  res.end("Hello World\n");
});

server.listen(port, hostname, () => {
  console.log(`Server running at http://localhost:${port}/`);
});

将其保存在文件'echo.js'中，并按如下方式运行:

$ node echo.js
Server running at http://localhost:3000/

然后你可以提交数据:

$ curl -d "[1,2,3]" -XPOST http://localhost:3000/foo/bar

这将显示在服务器的标准输出:

POST /foo/bar
{ host: 'localhost:3000',
  'user-agent': 'curl/7.54.1',
  accept: '*/*',
  'content-length': '7',
  'content-type': 'application/x-www-form-urlencoded' }
BODY: [1,2,3]

我不确定是否有人愿意花这么大的力气来测试GET和POST调用。我使用Python Flask模块并编写了一个函数，该函数的功能类似于@Robert共享的功能。

from flask import Flask, request
app = Flask(__name__)

@app.route('/method', methods=['GET', 'POST'])
@app.route('/method/<wish>', methods=['GET', 'POST'])
def method_used(wish=None):
    if request.method == 'GET':
        if wish:
            if wish in dir(request):
                ans = None
                s = "ans = str(request.%s)" % wish
                exec s
                return ans
            else:
                return 'This wish is not available. The following are the available wishes: %s' % [method for method in dir(request) if '_' not in method]
        else:
            return 'This is just a GET method'
    else:
        return "You are using POST"

当我运行这个时，如下所示:

C:\Python27\python.exe E:/Arindam/Projects/Flask_Practice/first.py
 * Restarting with stat
 * Debugger is active!
 * Debugger PIN: 581-155-269
 * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

现在让我们打几通电话。我正在使用浏览器。

我一直在使用这个REST API: https://restful-api.dev

它无限期地存储所创建的对象。 此外，该模式非常灵活，您可以传递任何JSON数据。

我是一个前端开发人员，当我需要创建一些示例数据时，这是非常有用的。这是我能找到的唯一一家不需要注册或代币就能免费使用的。
