英文:
Error when fetching URL through proxy in Go
问题
这与这个问题有关。我正在使用这段简单的代码通过代理获取一个URL：
package main
import (
"fmt"
"io/ioutil"
"net/http"
"net/url"
)
func main() {
proxyUrl, err := url.Parse("87.236.233.92:8080")
httpClient := &http.Client { Transport: &http.Transport { Proxy: http.ProxyURL(proxyUrl) } }
response, err := httpClient.Get("http://stackoverflow.com")
if err != nil {
fmt.Println(err.Error())
} else {
body, _ := ioutil.ReadAll(response.Body)
fmt.Println("OK: ", len(body))
}
}
如果我运行这段代码，我会得到这个错误：
Get http://stackoverflow.com: http: error connecting to proxy 87.236.233.92:8080: GetServByName: The requested name is valid, but no data of the requested type was found.
我知道代理地址是有效的，如果我通过其他方式通过代理获取URL，它是可以工作的。有任何想法为什么我会得到这个错误吗？

This is related to this other question. I'm fetching a URL through a proxy using this simple code:
package main
import (
"fmt"
"io/ioutil"
"net/http"
"net/url"
)
func main() {
proxyUrl, err := url.Parse("87.236.233.92:8080")
httpClient := &http.Client { Transport: &http.Transport { Proxy: http.ProxyURL(proxyUrl) } }
response, err := httpClient.Get("http://stackoverflow.com")
if err != nil {
fmt.Println(err.Error())
} else {
body, _ := ioutil.ReadAll(response.Body)
fmt.Println("OK: ", len(body))
}
}
If I run this code, I am getting this error:
> Get http://stackoverflow.com: http: error connecting to proxy 87.236.233.92:8080: GetServByName: The requested name is valid, but no data of the requested type was found.
I know that the proxy address is valid and if I fetch the URL through the proxy by other means it work. Any idea why I'm getting this error?

使用http://来指定您的代理，它应该可以工作，例如
proxyUrl, err := url.Parse("http://87.236.233.92:8080")
if err != nil {
fmt.Println("代理URL无效", err)
return
}
英文:
Specify your proxy with http:// in and it should work, eg
proxyUrl, err := url.Parse("http://87.236.233.92:8080")
if err != nil {
fmt.Println("Bad proxy URL", err)
return
}
