wget获取https资源

使用wget获取 https资源，缺省命令下是要使用证书，如果还未安装证书，可以选择忽略。

　　例如没有github.com的证书，执行如下命令

mkdir -p model
cd model
wget  https://github.com/dmlc/web-data/raw/master/mxnet/neural-style/model/vgg19.params
cd ..

mkdir -p input
cd input
wget https://github.com/dmlc/web-data/raw/master/mxnet/neural-style/input/IMG_4343.jpg
wget  https://github.com/dmlc/web-data/raw/master/mxnet/neural-style/input/starry_night.jpg
cd ..

mkdir -p output

　　会报错，

ERROR: cannot verify github.com's certificate, issued by `/C=US/O=DigiCert Inc/OU=www.digicert.com/CN=DigiCert SHA2 Extended Validation Server CA':
  Unable to locally verify the issuer's authority.
To connect to github.com insecurely, use `--no-check-certificate'.

　　此时，加上 --no-check-certificate  选项，忽略证书检查，如下

#!/bin/bash

mkdir -p model
cd model
wget --no-check-certificate https://github.com/dmlc/web-data/raw/master/mxnet/neural-style/model/vgg19.params
cd ..

mkdir -p input
cd input
wget --no-check-certificate https://github.com/dmlc/web-data/raw/master/mxnet/neural-style/input/IMG_4343.jpg
wget --no-check-certificate https://github.com/dmlc/web-data/raw/master/mxnet/neural-style/input/starry_night.jpg
cd ..

mkdir -p output
