go-get在升级到go 1.10后失败，导入路径无法识别

设置代理之前：

$go get-u google.golang.org/grpc

package google.golang.org/grpc: unrecognized import path "google.golang.org/grpc" (https fetch: Get https://google.golang.org/grpc?go-get=1: dial TCP 172.217.160.145:443: connected: 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.)

package google.golang.org/grpc: unrecognized import path "google.golang.org/grpc" (https fetch: Get https://google.golang.org/grpc?go-get=1: proxyconnect tcp: EOF)

设置代理后：

$go get-u google.golang.org/grpc

package google.golang.org/grpc: unrecognized import path "google.golang.org/grpc" (https fetch: Get https://google.golang.org/grpc?go-get=1: dial TCP 172.217.160.145:443: connected: 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.)

package google.golang.org/grpc: unrecognized import path "google.golang.org/grpc" (https fetch: Get https://google.golang.org/grpc?go-get=1: proxyconnect tcp: EOF)

我已经尝试了在StackOverflow上找到的所有解决方案。我仍然无法解决这个问题

如何解决此问题？

始终将HTTP\u代理和HTTPS\u代理设置为HTTP URL

代理本身应该通过http访问，即使您的URL查询是https

您是否将http_代理和https_代理都设置为http（非https）URL？我将http_代理设置为http URL，将https_代理设置为https URL我将https_代理重置为具有http URL，并且成功了！真不敢相信这就是问题所在！谢谢@VonC！这是否意味着与代理服务器的连接应始终是

http

？我们不能通过任何方式与代理服务器建立https连接吗？@kasuniyambalapitiya这是可能的，但不常见：。它是安全的“足够”：。另见
