Windows : make request on specific interface-CodePudding

I have 3 network interface plug in my pc (windows). I just wonder is there a easy way to make a http request from specific interface ?

I try curl but it seem not support windows.

Description here : https://curl.se/libcurl/c/CURLOPT_INTERFACE.html

libcurl does not support using network interface names for this option on Windows.

Here is my network details :

Ethernet adapter NETW 001:

   Connection-specific DNS Suffix  . :
   Link-local IPv6 Address . . . . . : fe80::8a7:9368:bb58:1883
   IPv4 Address. . . . . . . . . . . : 192.168.5.252
   Subnet Mask . . . . . . . . . . . : 255.255.255.0
   Default Gateway . . . . . . . . . : 192.168.5.1

Ethernet adapter NETW 002:

CodePudding user response：

It is not clear what stops you from using the specific interface by its IPv4 Address. The same manual:

Pass a char * as parameter. This sets the interface name to use as outgoing network interface. The name can be an interface name, an IP address, or a host name.

If the parameter starts with "host!" it is treated as either an IP address or a hostname.

#if 1
curl_easy_setopt(curl, CURLOPT_INTERFACE, "192.168.78.252");
#else
curl_easy_setopt(curl, CURLOPT_INTERFACE, "host!192.168.78.252");
#endif
