curl HTTP Header

 

對於"User-Agent", "Cookie", "Host"這類標准的HTTP頭部字段，通常會有另外一種設置方法。curl命令提供了特定的選項來對這些頭部字段進行設置：

• -A (or --user-agent): 設置 "User-Agent" 字段.
• -b (or --cookie): 設置 "Cookie" 字段.
• -e (or --referer): 設置 "Referer" 字段.

例如，以下兩個命令是等效的。這兩個命令同樣都對HTTP頭的"User-Agent"字符串進行了更改。

1. $ curl -H "User-Agent: my browser" http://cnn.com
2. $ curl -A "my browser" http://cnn.com

wget是另外一個類似於curl，可以用來獲取URL的命令行工具。並且wget也一樣允許你使用一個自定義的HTTP頭。點擊 這里查看wget命令的詳細信息。

-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.

Example:

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

You can see the request that curl sent by adding the -v option.
