Parsing S3 URI into bucket and key in Go
问题
在官方的AWS Go SDK中似乎没有一个函数可以解析类似s3://格式的URI字符串（例如s3://mybucket/some/place/on/there.gz）并提供桶（bucket）和键（key）等信息。Java SDK中有一个类似的函数。我是否忽略了Go SDK没有这样的明显原因？
这个问题涉及到保持兼容性。一个SDK函数提供了一个明确的方法来正确解析S3地址，并避免了url.Parse()等函数可能忽略的细微情况的担忧。
英文:
There doesn't seem to be a function in the official AWS Go SDK that'll parse an s3:// style URI-like string (i.e. s3://mybucket/some/place/on/there.gz) and provide things like the bucket and key. The Java SDK has such a function. Am I missing an obvious reason why the Go SDK does not?
This question is about maintaining compatibility. An SDK function provides a clear authority on how to properly parse S3 addresses and deters worry over subtle cases that url.Parse() and ilk may miss.

尽管只有AWS开发人员能回答实际问题（为什么这不包含在SDK中），但有一个简单的答案：S3 URL是URL，你可以使用net/url来解析它们：
u, _ := url.Parse("s3://mybucket/some/place/on/there.gz")
fmt.Printf("proto: %q, bucket: %q, key: %q", u.Scheme, u.Host, u.Path)

Though only the AWS devs can answer the actual question (why isn't this included in the SDK), there is the simple answer: S3 URLs are URLs, and you can use net/url to parse them:
u,_ := url.Parse("s3://mybucket/some/place/on/there.gz")
fmt.Printf("proto: %q, bucket: %q, key: %q", u.Scheme, u.Host, u.Path)
