如何解析DELPHI XE5服务器返回的JSON数据(翻译)及中文乱码
[plain] view plain copy print?
- <span style="font-size:14px;">一直想找如何解析JSON数据的说,今天终于找到有人发帖子了。之前有人说用superobject,Tlkjson,delphi json library,delphi web unit等等。其实我是想找比较简单的解析方式。解析简单的json。下面是转载的坦然的源码。
- </span>
[delphi] view plain copy print?
- unit Unit1;
- interface
- uses
- Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics,
- Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.StdCtrls,DBXJSON;
- type
- TForm1 = class(TForm)
- Button1: TButton;
- procedure Button1Click(Sender: TObject);
- private
- { Private declarations }
- public
- { Public declarations }
- end;
- var
- Form1: TForm1;
- implementation
- {$R *.dfm}
- const
- GJSONString =
- ‘{‘ +
- ‘ "name": {‘+
- ‘ "A JSON Object": {‘ +
- ‘ "id": "1"‘ +
- ‘ },‘ +
- ‘ "Another JSON Object": {‘ +
- ‘ "id": "2"‘ +
- ‘ }‘ +
- ‘ },‘ +
- ‘ "totalobjects": "2"‘ +
- ‘}‘;
- procedure TForm1.Button1Click(Sender: TObject);
- var
- LJSONObject: TJSONObject;
- Value: TJSONValue;
- begin
- LJSONObject := nil;
- try
- LJSONObject := TJsonObject.Create;
- Value := TJSONValue.Create;
- { convert String to JSON }
- LJSONObject.Parse(BytesOf(GJSONString), 0);
- Value :=LJSONObject.GetValue(‘name‘);
- ShowMessage(Value.ToString);
- finally
- LJSONObject.Free;
- end;
- end;
- end.
灰常好,在此谢谢博主。
但是这样处理中文的时候会出现乱码现象。我对代码稍微修改了一下:
[delphi] view plain copy print?
- var
- jo:tjsonobject;
- jv:tjsonvalue;
- jsonstr:string;//要转换的json字符串
- begin
- jo:=nil;
- jsonstr:=‘{"name":"流川枫","interest":"与樱木吵架"};
- try
- jo:=tjsonobject.create;
- jo:=tjsonobject.parsejsonvalue(tencoding.utf8.getbytes(jsonstr),0) as tjsonobject;
- jv:=jo.get(‘interest‘).jsonvalue;
- showmessage(jv.value);
- finally
- jo.Free;
- end;
- end;
终于能转换成中文了。
下面是关于jsonobject的解析(举一反三):
[delphi] view plain copy print?
- procedure TForm1.Button1Click(Sender: TObject);
- var
- jsonstr: string;
- jvalue: tjsonvalue;
- jobj: tjsonobject;
- jpair: tjsonpair;
- jarray: tjsonarray;
- begin
- jsonstr:=‘{‘name‘:‘tom‘,‘password‘:‘tomcat‘,‘interests‘:[‘mouse‘,‘meat‘]}‘;
- jvalue := tjsonobject.ParseJSONValue
- (tencoding.UTF8.GetBytes(jsonstr), 0);
- try
- jobj := jvalue as tjsonobject;
- jpair := jobj.Get(2); // get the third json pair
- jarray := jpair.JsonValue as tjsonarray; // pair value is an array [‘mouse‘,‘meat‘]
- strresult := jarray.Get(0).value; // first element of array[‘mouse‘,‘meat‘]
- showmessage(strresult);//it is mouse
- finally
- jvalue.Free;
- end;
- end;
