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。

Nc一行本地测试服务器

在Linux下用一行设置本地测试服务器:

nc -kdl localhost 8000

另一个shell上的请求生成器示例:

wget http://localhost:8000

然后在第一个shell中，你看到请求显示出来:

GET / HTTP/1.1
User-Agent: Wget/1.19.4 (linux-gnu)
Accept: */*
Accept-Encoding: identity
Host: localhost:8000
Connection: Keep-Alive

netcat-openbsd包中的nc是广泛可用的，并且已预先安装在Ubuntu上。

在Ubuntu 18.04上测试。

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。

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.

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。
