Delphi调用REST

Delphi调用REST很简单,首先在界面上放上:

RESTClient1: TRESTClient;
RESTRequest1: TRESTRequest;
RESTResponse1: TRESTResponse;

然后简单调用即可:

RESTClient1.BaseURL:=edtURL.Text;
RESTRequest1.Execute;
memLog.Text:=RESTResponse1.Content;

还可以对结果进行进一部处理,比如解析JSON:

procedure TfrmMain.btnGetClick(Sender: TObject);
var
jo,jo2:TJSONObject;
jv:TJSONValue;
ja:TJSONArray;
jp:TJSONPair;
i:Integer;
begin
RESTClient1.BaseURL:=edtURL.Text;
RESTRequest1.Execute;
memLog.Text:=RESTResponse1.Content; jo:=TJSONObject.Create;
ja:=jo.ParseJSONValue(RESTResponse1.Content) as TJSONArray;
for jv in ja do
begin
jo2:=jv as TJSONObject;
for i:= to jo2.Count- do
begin
jp:=jo2.Pairs[i];
memLog.Lines.Add(jp.JsonString.ToString+':'+jp.JsonValue.ToString);
end;
end; end;

在这里我使用的是Delphi自带的JSON解析,注意引用单元system.json。
