Go Lang-Gin：如何从httputil.DumpRequest中仅提取主体（并忽略其他垃圾）

Question

I know that you can get the body content from

ioutil.ReadAll(c.Request.Body)

But using httputil.DumpRequest

dump, err := httputil.DumpRequest(c.Request, true)

will give the body contents along with other values, the body content in the end.

Content type: application/json IP: 127.0.0.1:36846 header token: Content length: 76 Request Method: POST Request URL: /signup Body: POST /signup HTTP/1.1 Host: 127.0.0.1:8080 Accept: / Accept-Encoding: gzip,deflate Accept-Language: en-US,en;q=0.8 Connection: keep-alive Content-Type: application/json Origin: chrome-extension://hgmloofddffdnphfgcellkdfbfbjeloo User-Agent: Mozilla/5.0 (X11; Linux i686) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/38.0.2125.101 Safari/537.36 {"fname":"aFirstName", "lname":"aLName", "email":"[e-mail]", "password":"123"}

Is there an efficient way I can get only the body content from httputil.DumpRequest()? i.e In this case only

{"fname":"aFirstName", "lname":"aLName", "email":"[e-mail]", "password":"123"}

Answer 1

You don't use httputil.DumpRequest for that, that's a debug function.

Assuming you want to parse json you can do something like this:

defer c.Request.Body.Close()
var data yourDataType
if err := json.NewDecoder(c.Request.Body).Decode(&data); err != nil {
    // handle error
}
// handle data
