我希望通过cURL调用向我的Linux Apache服务器发送标头。如何实现这一点?
-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.
curl --header "X-MyHeader: 123" www.google.com
curl --header "Accept: text/javascript" --header "X-Test: hello" -v www.google.com
可以通过添加-v
选项来查看curl发送的请求。获取(GET):
使用JSON格式:
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
POST:
用于发布数据:
curl --data "param1=value1¶m2=value2" http://hostname/resource
文件上传:
curl --form "fileupload=@filename.txt" http://hostname/resource
RESTful HTTP Post:
curl -X POST -d @filename http://hostname/resource
用于登录网站(认证):
curl -d "username=admin&password=admin&submit=Login" --dump-header headers http://localhost/Login
curl -L -b headers http://localhost/
Accept
头部是为了 客户端(发出请求)想要的内容,但 Content-Type
头部只是服务器的 回答,没有更多意义,它不是客户端的意愿:“我想要这种类型的内容”。对吗?所以对于 GET 请求 curl -i -H "Accept: application/json" http://hostname/resource
应该就可以了。我错了吗?请参见 https://developer.mozilla.org/zh-CN/docs/Web/HTTP/Headers/Content-Type 《在响应中,Content-Type
首部告诉客户端实际返回的内容类型。》 - andreas.naturwikiContent-Type
,而不是请求。Content-Type
始终指的是两个参与方之间传输的数据类型。如果它在请求头中,这意味着客户端告诉服务器“是的,我正在向您发送数据类型为application/json
”。如果它在响应中,则表示服务器告诉客户端“现在我正在向您发送数据类型为text/plain
”。 - fa wildchild在 PHP 中:
curl_setopt($ch, CURLOPT_HTTPHEADER, array('HeaderName:HeaderValue'));
或者你可以设置多个:
curl_setopt($ch, CURLOPT_HTTPHEADER, array('HeaderName:HeaderValue', 'HeaderName2:HeaderValue2'));
获取(多个参数):
curl -X GET "http://localhost:3000/action?result1=gh&result2=ghk"
或者。curl --request GET "http://localhost:3000/action?result1=gh&result2=ghk"
或者curl "http://localhost:3000/action?result1=gh&result2=ghk"
或者curl -i -H "Application/json" -H "Content-type: application/json" "http://localhost:3000/action?result1=gh&result2=ghk"
你也可以像这样在单个Curl调用中发送多个标头、数据(例如JSON),并指定调用方法(POST、GET):
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",
}
]
}'
如果您想发送自定义头部,可以按照以下方式进行:
curl -v -H @{'custom_header'='custom_header_value'} http://localhost:3000/action?result1=gh&result2=ghk
{'custom_header'='custom_header_value'}
的文件中读取头信息吗? - Robin A. Meadecurl.exe http://127.0.0.1:5000/books
发布或更新数据,例如:
curl.exe http://127.0.0.1:5000/books/8 -X PATCH -H "Content-Type: application/json" -d '{\"rating\":\"2\"}'
提示: 为json数据添加反斜杠来避免此类型错误 => Failed to decode JSON object: Expecting value: line 1 column 1 (char 0)
并且仅使用curl.exe
而不是curl
来避免此问题:
