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.

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。

Webhook Tester是一个很好的工具:https://webhook.site (GitHub)

对我来说很重要的是，它显示了请求者的IP，当您需要将一个IP地址列入白名单但不确定它是什么时，这很有帮助。

下面是一个邮差回声:https://docs.postman-echo.com/

例子:

curl --request POST \
  --url https://postman-echo.com/post \
  --data 'This is expected to be sent back as part of response body.'

回应:

{"args":{},"data":"","files":{},"form":{"This is expected to be sent back as part of response body.":""},"headers":{"host":"postman-echo.com","content-length":"58","accept":"*/*","content-type":"application/x-www-form-urlencoded","user-agent":"curl/7.54.0","x-forwarded-port":"443","x-forwarded-proto":"https"},"json":{"...

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]
