今天，打算用golang的echo（https://github.com/labstack/echo）框架做一個(gè)demo，在按照其安裝手冊(cè)安裝echo框架時(shí)，使用dep命令，如下：
dep ensure -add github.com/labstack/echo@^3.1
但是徐裸，雖然的git已經(jīng)設(shè)置了代理，但是依然報(bào)錯(cuò)啸盏，如下：
Solving failure: unable to deduce repository and source type for "golang.org/x/crypto": unable to read metadata: unable to fetch raw metadata: failed HTTP request to URL "http://golang.org/x/crypto?go-get=1": Get http://golang.org/x/crypto?go-get=1: dial tcp 216.239.37.1:80: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
后面重贺，終于在?https://github.com/golang/dep/issues/1322 中找到原因，解決方法如下：
if you have a proxy client put your proxy on in you cmd: run set http_proxy=ip:port before use dep ensure.example(windows):
set http_proxy=127.0.0.1:1235
set https_proxy=127.0.0.1:1235
it can visit golang.org to fix this issus
按照這個(gè)方式宫补，終于解決了這個(gè)問(wèn)題
