在PHP中：

curl_setopt($ch, CURLOPT_HTTPHEADER, array('HeaderName:HeaderValue'));

或者可以设置多个：

curl_setopt($ch, CURLOPT_HTTPHEADER, array('HeaderName:HeaderValue', 'HeaderName2:HeaderValue2'));

您还可以将多个标头、数据（例如JSON）和指定Call方法（POST、GET）发送到单个CUrl调用中，如下所示：

curl -X POST(Get or whatever) \
  http://your_url.com/api/endpoint \
  -H 'Content-Type: application/json' \
  -H 'header-element1: header-data1' \
  -H 'header-element2: header-data2' \

  -d '{
  "JsonExArray": [
    {
      "json_prop": "1",
    },
    {
      "json_prop": "2",
    }
  ]
}'

GET:

使用JSON：

curl -i -H "Accept: application/json" -H "Content-Type: application/json" http://hostname/resource

使用XML:

curl -H "Accept: application/xml" -H "Content-Type: application/xml" -X GET http://hostname/resource

职位：

对于过帐数据：

curl --data "param1=value1&param2=value2" http://hostname/resource

对于文件上载：

curl --form "fileupload=@filename.txt" http://hostname/resource

RESTful HTTP发布：

curl -X POST -d @filename http://hostname/resource

对于登录站点（auth）：

curl -d "username=admin&password=admin&submit=Login" --dump-header headers http://localhost/Login
curl -L -b headers http://localhost/

在通过窗口的anaconda环境中，命令应该是：GET，例如：

curl.exe http://127.0.0.1:5000/books 

发布或修补数据，例如：

curl.exe http://127.0.0.1:5000/books/8 -X PATCH -H "Content-Type: application/json" -d '{\"rating\":\"2\"}' 

PS：为json数据添加反斜杠以避免此类错误=>未能解码json对象：期望值：第1行第1列（char 0）

使用curl.exe而不是curl来避免这个问题：

Invoke-WebRequest : Cannot bind parameter 'Headers'. Cannot convert the "Content-Type: application/json" value of type
"System.String" to type "System.Collections.IDictionary".
At line:1 char:48
+ ... 0.1:5000/books/8 -X PATCH -H "Content-Type: application/json" -d '{\" ...

男士卷发：

   -H/--header <header>
          (HTTP)  Extra header to use when getting a web page. You may specify
          any number of extra headers. Note that if you should  add  a  custom
          header that has the same name as one of the internal ones curl would
          use, your externally set header will be used instead of the internal
          one.  This  allows  you  to make even trickier stuff than curl would
          normally do. You should not replace internally set  headers  without
          knowing  perfectly well what you're doing. Remove an internal header
          by giving a replacement without content on the  right  side  of  the
          colon, as in: -H "Host:".

          curl  will  make sure that each header you add/replace get sent with
          the proper end of line marker, you should thus not  add  that  as  a
          part  of the header content: do not add newlines or carriage returns
          they will only mess things up for you.

          See also the -A/--user-agent and -e/--referer options.

          This option can be used multiple times to add/replace/remove  multi-
          ple headers.

示例1：单标题

curl --header "X-MyHeader: 123" www.google.com

示例2：多个标头

curl --header "Accept: text/javascript" --header "X-Test: hello" -v www.google.com

您可以看到curl通过添加-v选项发送的请求。

GET（多个参数）：

curl -X  GET "http://localhost:3000/action?result1=gh&result2=ghk"

or

curl --request  GET "http://localhost:3000/action?result1=gh&result2=ghk"

or

curl  "http://localhost:3000/action?result1=gh&result2=ghk"

or

curl -i -H "Application/json" -H "Content-type: application/json"  "http://localhost:3000/action?result1=gh&result2=ghk"
