This worked for me (linux):

module main

import net.http

fn main() {
	a := http.get('http://www.baidu.com')!
	println('${a.body.len}')
	b := http.post('http://www.baidu.com', '')!
	println('${b.body.len}')
}

$ v run 24226.v
514029
19825
$ v version
V 0.4.10 711470d

Tested in windows and worked too.

It works for me on linux.

This may be more of a networking issue, as in @jemuky internet connection, rather than a problem with V.

Does the "v -d use_openssl" work here too? See: https://github.com/vlang/v/issues/23717

it doesn't work too, the error is "builder error: 'openssl/rand.h' not found", i think it use the openssl.exe of git path, its version is "OpenSSL 1.1.1m 14 Dec 2021" then, i install the new version(OpenSSL 3.5.0 8 Apr 2025 (Library: OpenSSL 3.5.0 8 Apr 2025)) openssl, but the openssl.exe of git is still effective, and I can't specify the new one I installed to take effect then, so the post request can't work too

[BadaBingBee]

which version shows when you run?: openssl --version

Mine is (on linux): OpenSSL 3.2.4 11 Feb 2025 (Library: OpenSSL 3.2.4 11 Feb 2025)

It sounds like "v -d use_openssl" isn't finding your openssl?

Your code works for me with or without the "use_openssl" flag, but I do get the same error on a different endpoint, "V panic: result not set (response does not start with HTTP/, line: ``", and the flag makes it work in that case.

you're right, It's a problem with openssl

i entered openssl --version, it shows OpenSSL 1.1.1m 14 Dec 2021, it is the same as the openssl.exe of git path, so I upgraded it to no avail, because git is also what i need

so i can't specify which openssl i need to use

[JalonSolov]

From the github repo page for V:

On Windows, OpenSSL is simply hard to get working correctly. The instructions here may (or may not) help.

this method is invalid.

then I moved the newly installed openssl environment variable to the top of PATH, then the version is correct.

then i compiled this program, and the program can't work. My program name is "test.exe", and I entered "dumpbin /dependents .\test.exe", it shows

       30000 .stabstr
       9D000 .text

then I entered "which user32", it shows "/usr/bin/which: no user32 in (xxxx)"(xxxx is the PATH), the "libssl-3-x64"is the same as this then I entered "which user32.dll", it shows "/c/Windows/system32/user32.dll", "which libssl-3-x64.dll" is "/c/Program Files/OpenSSL-Win64/bin/libssl-3-x64.dll" so, does vlang need to be linked as libssl-3-x64.dll, instead of libssl-3-x64? And I used "dumpbin /dependents" on another cpp program that linked libcurl and saw

The link of this program is xxx.dll, so I think some versions of Windows may require the ".dll" suffix to link to dynamic libraries.
