fail to build cargo behind proxy

[Jfromchina]

I am trying to build cargo from source behind a proxy, It tells like this:

$ cargo build --verbose
Updating registry https://github.com/rust-lang/crates.io-index
failed to fetch https://github.com/rust-lang/crates.io-index

Caused by:
[12] SSL error: error:140E0114:SSL routines:SSL_shutdown:uninitialized

I have configed environment variables like this:
export HTTP_PROXY=proxy.example.com:8000
export HTTPS_PROXY=proxy.example.com:8000
export FTP_PROXY=proxy.example.com:8000

there is no config file under .cargo dir，does it because of this? what can I do next? By the way, dose the git need to config either? how? I am a new user for Rust, thanks a lot!

Does curl work for you behind the proxy? Is the proxy trying to do some funny SSL business? If the proxy is trying to give you an invalid certificate then this is likely to happen. Lots more info can be found in #636

I spoke to @Jfromchina in person; he (or we) think fixing #1180 would address this. (By "fixing" I mean adding the suggested config setting in the Cargo.toml)

Ok, in that case I'm going to close this in favor of that
