Golang several post modes

With Golang HTTP request type is much, summary of the memo.

1. Common Post\get Requests

varr http. Request R.parseform () r.form.add ( "UUID", orderuuid) Bodystr: = Strings. Trimspace (R.form.encode ()) request, Err: = http. Newrequest ("GET", URL, strings. Newreader (BODYSTR))ifErr! =Nil {//todo:} request. Header.set ("Content-type","application/x-www-form-urlencoded") Request. Header.set ("Connection","keep-alive")    varRESP *http. Response resp, err=http. Defaultclient.do (Request)ifErr! =Nil {//todo:    }

2. Body all binary data stream for post

//body commits binary dataFunc dobytespost (URLstring, data []byte) ([]byte, error) { body: = bytes. Newreader (data) request, err:=http. Newrequest (post_method, url, body)ifErr! =Nil {log. Println ("http. newrequest,[err=%s][url=%s]", err, URL)return[]byte(""), err}Request. Header.set ("Connection","keep-alive")    varRESP *http. Response resp, err=http. Defaultclient.do (Request)ifErr! =Nil {log. Println ("http. Do failed,[err=%s][url=%s]", err, URL)return[]byte(""), err} defer resp. Body.close () b, err:=Ioutil. ReadAll (resp. Body)ifErr! =Nil {log. Println ("http. Do failed,[err=%s][url=%s]", err, URL)} returnB, err}

3. Simulate Web Form file upload for post

Func newfileuploadrequest (URIstring,paramsmap[string]string, ParamName, Pathstring) (*http. Request, error) {file, err:=OS. Open (PATH)ifErr! =Nil {returnNil, err} defer file. Close () body: = &bytes. buffer{} Writer: = multipart. Newwriter (body) part, err: = writer. Createformfile (paramname, path) if err! = Nil {return nil, err} _, err = Io. Copy (part, file) forKey, Val: = Rangeparams {        _ =writer. Writefield (Key, Val)} Err=writer. Close ()ifErr! =Nil {returnnil, err} request, err:= http. Newrequest ("POST", URI, body) request. Header.set ("Content-type", writer. Formdatacontenttype ())returnrequest, err}
