问题描述
我在Go中制作一个URL获取器，并拥有要获取的URL列表。我向每个URL发送 http.Get（）请求并获得他们的回复。
I'm making a URL fetcher in Go and have a list of URLs to fetch. I send http.Get() requests to each URL and obtain their response.
resp,fetch_err := http.Get(url)
如何设置自定义超时为每个获取请求？ （默认时间非常长，这使得我的fetcher真的很慢。）我希望我的fetcher有大约40-45秒的超时时间，之后它应该返回请求超时并转到下一个URL。
How can I set a custom timeout for each Get request? (The default time is very long and that makes my fetcher really slow.) I want my fetcher to have a timeout of around 40-45 seconds after which it should return "request timed out" and move on to the next URL.
我该如何实现这一目标？
How can I achieve this?
推荐答案
显然，在Go 1.3 有Timeout字段
Apparently in Go 1.3 http.Client has Timeout field
timeout := time.Duration(5 * time.Second)
client := http.Client{
Timeout: timeout,
}
client.Get(url)
这对我来说已经完成了。
That's done the trick for me.
