In my project, I have a byte slice from a request's response.
defer resp.Body.Close()
if resp.StatusCode != http.StatusOK {
log.Println("StatusCode为" + strconv.Itoa(resp.StatusCode))
return
}
respByte, err := ioutil.ReadAll(resp.Body)
if err != nil {
log.Println("fail to read response data")
return
}
This works, but if I want to get the response's body for io.Reader
, how do I convert? I tried the newreader/writer but wasn't successful.
To get a type that implements io.Reader
from a []byte
slice, you can use bytes.NewReader
in the bytes
package:
r := bytes.NewReader(byteData)
This will return a value of type bytes.Reader
which implements the io.Reader
(and io.ReadSeeker
) interface.
Don't worry about them not being the same "type". io.Reader
is an interface and can be implemented by many different types. To learn a little bit more about interfaces in Go, read Effective Go: Interfaces and Types .
r := strings(byteData)
这也适用于将[]byte
转换为io.Reader
