如何通过 curl 调用使用 HTTP 请求发送标头?

我希望将标头发送到 Linux 机器上的 Apache 服务器。如何通过 curl 调用实现此目标?

答案

man curl

-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.

例:

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

您可以通过添加-v选项来查看 curl 发送的请求。

得到:

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

开机自检:

对于过帐数据:

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

对于文件上传:

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

RESTful HTTP 发布:

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

用于登录站点(身份验证):

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

PHP 中

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

或者您可以设置多个:

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

GET(多个参数):

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

要么

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

要么

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

要么

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

您还可以发送多个标头,数据(例如 JSON),并在单个 CUrl 调用中指定 Call 方法(POST,GET),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' \

...... 更多标题...

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

我用邮递员。

执行您想执行的任何呼叫。然后,邮递员提供了一个方便的工具来显示卷曲代码。

在终端中运行它。 在此处输入图片说明

我已经从 curl 转到Httpie 了 ;语法如下:

http http://myurl HeaderName:value

如果要发送自定义标头 ,则可以采用以下方式:

curl -v -H @{'custom_header'='custom_header_value'} http://localhost:3000/action?result1=gh&result2=ghk
