plugins_api() does not fetch plugin information since moving to wp_remote_post()

[ryan]

api.wordpress.org is returning a "Slug not provided" error. Works on one blog but not on another.

[ryan]

Debug attached. A blog using the same get and post transports as the failed blog works fine.

[jacobsantos]

Might have to do with the different transports. I've not seen this problem. Can you send what is being transferred, I might be able to write a test script for debugging.

Dump of $strHeader and $strResponse from WP_Http_Fsockopen::request()

[ryan]

A little more debug.

arg_separator.output is '&' on the broken blog. http_build_query() uses '&' instead of '&' to builf the body in that case.

Replying to ryan:

arg_separator.output is '&' on the broken blog. http_build_query() uses '&' instead of '&' to builf the body in that case.

Build query should then define the arg separator parameter to be '&' always. Easy fix then.

[jacobsantos]

Okay, yeah, you already had a patch that does that.

[jacobsantos]

I'm glad it was an easy fix.

(In [8648]) Always use '&' as arg separator when building the body. fixes #7522
