在我的Cenos服务器上无法获取go-assets，结果如下：
MRYQULAX> go get github.com/jessevdk/go-assets
# cd .; git clone -- https://github.com/jessevdk/go-assets /users/mryqu/go/src/github.com/jessevdk/go-assets
Cloning into '/users/mryqu/go/src/github.com/jessevdk/go-assets'...
fatal: unable to access 'https://github.com/jessevdk/go-assets/': SSL connect error
package github.com/jessevdk/go-assets: exit status 128
看了一下我的git版本是1.7.1，先升级一下试试吧。
export VER="2.31.0"
wget https://github.com/git/git/archive/v${VER}.tar.gz
tar -xvf v${VER}.tar.gz
rm -f v${VER}.tar.gz
cd git-*
make configure
sudo ./configure --prefix=/usr
sudo make
sudo make install
升级完成后，还是无法获取go-assets。
调试一下ssh方式：
MRYQULAX> ssh -vT git@github.com

发现没有去查找我的github key文件。
在~/.ssh/config文件中添加：
host *github.com
Protocol 2
User mryqu
IdentityFile ~/.ssh/github_rsa
再次测试：

在~/.gitconfig中添加如下内容：
[url "git@github.com:"]
insteadOf = https://github.com
[remote "origin"]
proxy =
[http]
sslVerify = false
sslBackend = openssl
现在一切顺利！
MRYQULAX>go get -u github.com/jessevdk/go-assets
