使用自定義 IP 發送 CURL 請求

難道不應該嗎？假設我不需要響應，我只想發送請求。我們不應該能夠更改 tcp/ip 標頭，因為我們的電腦會發送它嗎？我可能錯過了一些東西，只是真的很好奇，在大學裡學習它。

您可以使用以下-H/--header參數：

你可以欺騙你的IP地址：

curl --header "X-Forwarded-For: 192.168.0.2" http://example.com

範例：

客戶端

$ curl http://webhost.co.uk  

網路主機

$ tailf access.log | grep 192.168.0.54   
192.168.0.54 - - [10/Nov/2014:15:56:09 +0000] "GET / HTTP/1.1" 200 14328 "-"   
"curl/7.19.7 (x86_64-redhat-linux-gnu) libcurl/7.19.7 NSS/3.14.0.0 zlib/1.2.3   
libidn/1.18 libssh2/1.4.2"

更改 IP 地址的客戶端

$ curl --header "X-Forwarded-For: 192.168.0.99" http://webhost.co.uk   

網路主機

$ tailf access.log | grep 192.168.0.99  
192.168.0.99 - - [10/Nov/2014:15:56:43 +0000] "GET / HTTP/1.1" 200  
14328 "-" "curl/7.19.7 (x86_64-redhat-linux-gnu) libcurl/7.19.7 NSS/3.14.0.0  
zlib/1.2.3 libidn/1.18 libssh2/1.4.2"

-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:".
