Access HTTP response as string in Go

Question

I d like to parse the response of a web request  but I m getting trouble accessing it as string    func main         resp  err    http Get  http   google hu        if err    nil              handle error           defer resp Body Close       body  err    ioutil ReadAll resp Body       ioutil WriteFile  dump   body  0600       for i   0  i  lt  len body   i             fmt Println  body i       This logs uint8 and prints numbers            fmt Println  reflect TypeOf body        fmt Println  done       How can I access the response as string  ioutil WriteFile writes correctly the response to a file    I ve already checked the package reference but it s not really helpful

The method you re using to read the http body response returns a byte slice   func ReadAll r io Reader     byte  error    official documentation  You can convert   byte to a string by using  body  err    ioutil ReadAll resp Body  bodyString    string body

string byteslice  will convert byte slice to string  just know that it s not only simply type conversion  but also memory copy

bs    string body  should be enough to give you a string   From there  you can use it as a regular string   A bit as in this thread   var client http Client resp  err    client Get url  if err    nil       log Fatal err    defer resp Body Close    if resp StatusCode    http StatusOK       bodyBytes  err    ioutil ReadAll resp Body      if err    nil           log Fatal err            bodyString    string bodyBytes      log Info bodyString      See also GoByExample   As commented below  and in zzn s answer   this is a conversion  see spec   See  How expensive is   byte string     reverse problem  but the same conclusion apply  where zzzz mentioned      Some conversions are the same as a cast  like uint myIntvar   which just reinterprets the bits in place     Sonia adds      Making a string out of a byte slice  definitely involves allocating the string on the heap  The immutability property forces this    Sometimes you can optimize by doing as much work as possible with   byte and then creating a string at the end  The bytes Buffer type is often useful
