在golang中使用http.Client.Get方法和Body.Read（）方法处理时，EOF错误导致终止

I am using an http client to get a json body, and read it to a byte array like

client := new(http.Client)
client.Timeout = time.Second * 10
GetJobJson, err := client.Get(joblocation.String()) //where joblocation is of type *url.Url
if err != nil {
    errorlog.Err.Println("Error getting job from", joblocation.String(), err)
    return false, http.StatusBadRequest, nil
}
buff := make([]byte, GetJobJson.ContentLength)
length, err := GetJobJson.Body.Read(buff) //This returns an EOF error
if err != nil {
    errorlog.Err.Println("Error reading request body of length", length, "vs contentlength", GetJobJson.ContentLength, err)
    return false, http.StatusBadRequest, nil
}

GetJobJson.Bodyio.ReadCloserReaderRead

length, err := GetJobJson.Body.Read(buff) 

But since I am handling error here, it is returning an error which says EOF.

The http endpoint to where I am sending the request is running an apache server, mentioning it here since I am not sure if it matters.

If I am not handling the error, I get the complete json body, which is there in the remote server, and the program continues to work as expected.

Thank you.
