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。

一些在线httpbin:

https://httpbin.org/ https://httpbingo.org/ https://quic.aiortc.org/httpbin/

获取客户端ip，端口，ua..

http://ifconfig.io/

获取客户端ip, isp

你可以在本地运行Ken Reitz的httpbin服务器(在docker下或裸机上):

https://github.com/postmanlabs/httpbin

运行dockerized

docker pull kennethreitz/httpbin
docker run -p 80:80 kennethreitz/httpbin

直接在您的机器上运行

## install dependencies
pip3 install gunicorn decorator httpbin werkzeug Flask flasgger brotlipy gevent meinheld six pyyaml

## start the server
gunicorn -b 0.0.0.0:8000 httpbin:app -k gevent

现在，您在http://0.0.0.0:8000上运行了个人httpbin实例(对您的所有局域网可见)

Minimal Flask REST服务器

我想要一个返回预定义响应的服务器，所以我发现在这种情况下，使用一个最小的Flask应用程序更简单:

#!/usr/bin/env python3

# Install dependencies:
#   pip3 install flask

import json

from flask import Flask, request, jsonify

app = Flask(__name__)

@app.route('/', methods=['GET', 'POST'])
def root():
    # spit back whatever was posted + the full env 
    return jsonify(
        {
            'request.json': request.json,
            'request.values': request.values,
            'env': json.loads(json.dumps(request.__dict__, sort_keys=True, default=str))
        }
    )

@app.route('/post', methods=['GET', 'POST'])
def post():
    if not request.json:
        return 'No JSON payload! Expecting POST!'
    # return the literal POST-ed payload
    return jsonify(
        {
            'payload': request.json,
        }
    )

@app.route('/users/<gid>', methods=['GET', 'POST'])
def users(gid):
    # return a JSON list of users in a group
    return jsonify([{'user_id': i,'group_id': gid } for i in range(42)])

@app.route('/healthcheck', methods=['GET'])
def healthcheck():
    # return some JSON
    return jsonify({'key': 'healthcheck', 'status': 200})

if __name__ == "__main__":
    with app.test_request_context():
        app.debug = True
    app.run(debug=True, host='0.0.0.0', port=8000)

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";
}
?>

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.

看看PutsReq，它与其他类似，但它也允许您使用JavaScript编写您想要的响应。
