Gin: use c.Request.Body needs Close?

[iiinsomnia]

func Test(c *gin.Context) {
defer c.Request.Body.Close()

b, _ := ioutil.ReadAll(c.Request.Body)

fmt.Println(string(b))

}

@IIInsomnia I have the same question. so do we need manually close the Body?

You do not need to close requests' body. gin uses the original net/http package, net/http closes them automatically.

gin's handlers are called here.

and finishRequest() closes the body of requests.

Yes we don't need to close. I also found the related comments.

    // Body is the request's body.
    //
    // For client requests a nil body means the request has no
    // body, such as a GET request. The HTTP Client's Transport
    // is responsible for calling the Close method.
    //
    // For server requests the Request Body is always non-nil
    // but will return EOF immediately when no body is present.
    // The Server will close the request body. The ServeHTTP
    // Handler does not need to.
    Body io.ReadCloser
