哪里可以找到HTTP方法示例？

Question

HTTP定义了八种方法(有时称为"动词")

你能帮我找一下每个例子,这样我可以更好地测试和理解它们吗？

Answer 1

首先,您应该了解HTTP 1.1规范,尤其是节方法定义.

• 选项 获取有关服务器如何与之通信的信息.

  请求:

  OPTIONS * HTTP/1.1
  Host: example.com
  

  响应:

  HTTP/1.1 200 OK
  Date: …
  Allow: OPTIONS, GET, HEAD, POST, PUT, DELETE, TRACE
  Content-Length: 0
  

• GET 检索资源.

  请求:

  GET /foo/bar HTTP/1.1
  Host: example.com
  

  响应:

  HTTP/1.1 200 OK
  Date: …
  Content-Type: text/html;charset=utf-8
  Content-Length: 12345
   
  <!DOCTYPE …
  

• HEAD 和GET一样,但只返回HTTP头.

  请求:

  HEAD /foo/bar HTTP/1.1
  Host: example.com
  

  响应:

  HTTP/1.1 200 OK
  Date: …
  Content-Type: text/html;charset=utf-8
  Content-Length: 12345
  

• POST 创建新资源.

  请求:

  POST /foo/bar HTTP/1.1
  Host: example.com
  Content-Type: application/x-www-form-urlencoded
   
  action=addentry&subject=Hello,%20World
  

  响应:

  HTTP/1.1 201 Created
  Date: …
  Content-Length: 0
  Location: http://example.com/foo/bar        
  

• PUT 将数据发送到服务器.

• 删除 删除现有资源.

• TRACE 返回客户端发送的请求标头.

  请求:

  TRACE /foo/bar HTTP/1.1
  Host: example.com
  

  响应:

  HTTP/1.1 200 OK
  Date: …
  Content-Length: 17
   
  Host: example.com
  

我不确切知道这些例子是否正确.随意纠正它们.

Answer 2

您可以使用cURL命令行工具试验不同的HTTP方法.例如:

curl --head http://www.google.co.uk

HTTP/1.1 200 OK
Cache-Control: private, max-age=0
Date: Sun, 19 Apr 2009 15:33:24 GMT
Expires: -1
Content-Type: text/html; charset=ISO-8859-1
Set-Cookie: PREF=ID=a2a414b9a84c8ffd:TM=1240155204:LM=1240155204:S=16kZnqzeSxIJT3jv; expires=Tue, 19-Apr-2011 15:33:24 GMT; path=/; domain=.google.co.uk
Server: gws
Transfer-Encoding: chunked

• -X选项允许您指定GET以外的HTTP方法.
