Delphi中使用ISuperObject解析Json数据

　　Java、Php等语言中都有成熟的框架来解析Json数据，可以让我们使用很少的代码就把格式化好的json数据转换成程序可识别的对象或者属性，同时delphi中也有这样的组件来实现此功能，即IsuperObject。如果还没有这个组件的请在网上搜索下载或者在下面留言处留下你的邮箱向本人索取。

　　下面先说一下ISuperObject中几个常用的函数

function SO(const s: SOString = ‘{}’): ISuperObject; overload; 此函数传入json数据字符串，并返回一个ISuperObject对象，这一般是我们解析json时使用的第一个函数，如jObj := SO(jsonstr)。
property O[const path: SOString]: ISuperObject read GetO write PutO; default; 如：jobj.O[‘username’]，此函数被一个ISuperObject对象调用，方括号内的字符串为json中的字段名称，返回一个ISuperObject对象。
property S[const path: SOString]: SOString read GetS write PutS; 此函数被一个ISuperObject对象调用，和O[‘username’]不同的是，它返回的是一个SoString，即一个字符串，使用方法 str := jObj.S[‘username’]; 同理的还有其他几个类似的函数，如I[‘age’]返回整数，B[‘isenable’]返回布尔型，A[‘users’]返回一个TSuperArray数组
AsString, AsBoolean, AsInteger,AsArray，ISuperObject的函数，用来把ISuperObject转换成相应的数据类型。

　　下面我们看一个演示代码，json数据如下

{
    "retcode": "1", 
    "datafrom": "server",
    "users": "[{\"id\":1, \"username\": \"liuderu\", \"website\": \"bcoder.com\"},{\"id\":2, \"username\": \"Jeoe\", \"website\": \"baidu.com\"}]"
}

{

"retcode": "1",

"datafrom": "server",

"users": "[{\"id\":1, \"username\": \"liuderu\", \"website\": \"bcoder.com\"},{\"id\":2, \"username\": \"Jeoe\", \"website\": \"baidu.com\"}]"

}

　　Delphi版本2010，代码如下：

unit uFmMain;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls, ComCtrls, Buttons, superobject;

type
  TFmMain = class(TForm)
    Memo1: TMemo;
    ListView1: TListView;
    BitBtn1: TBitBtn;
    Label1: TLabel;
    procedure BitBtn1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  FmMain: TFmMain;

implementation

{$R *.dfm}

procedure TFmMain.BitBtn1Click(Sender: TObject);
var
  jRet, jUsers: ISuperObject;
  aryUsers: TSuperArray;
  retCode: integer;
  strUsers: string;
  i: integer;
begin
  jRet := SO(Memo1.Text);
  if (jRet.O['retcode'] <> nil) then begin
    retCode := jRet.O['retcode'].AsInteger;
    Label1.Caption := '返回值：' + IntToStr(retCode) + ';  数据来源：' + jRet.O['datafrom'].AsString;

    if(jRet.O['retcode'].AsInteger = 1) then begin
      strUsers := jRet.O['users'].AsString;
      jUsers := SO(strUsers);
      aryUsers := jUsers.AsArray;
      for I := 0 to aryUsers.Length - 1 do begin
        with  ListView1.Items.Add do begin
          Caption := aryUsers[i].O['id'].AsString;
          SubItems.Add(aryUsers[i].O['username'].AsString);
          SubItems.Add(aryUsers[i].O['website'].AsString);
        end;
      end;
    end;
  end;
end;

end.

jUsers := SO(strUsers);

aryUsers := jUsers.AsArray;

for I := 0 to aryUsers.Length - 1 do begin

with ListView1.Items.Add do begin

Delphi中不能更改工程选项处理办法

分类：Delphi, Other 阅读 (2,049) No Responses »

10月 072013

　　刚才在开发的时候，突然不能改变工程的图标和版本等信息了，把dof文件删除掉也不起作用。后来想起来，原来在前几天把工程默认的引用的资源文件的代码去掉了{$R *.res}，打开Project->View Source后，将{$R *.res}加到里面就可以了。如下所示：

program Project1;

uses
  Forms,
  Unit1 in 'Unit1.pas' {Form1};

{$R *.res}

begin
  Application.Initialize;
  Application.CreateForm(TForm1, Form1);
  Application.Run;
end.

program Project1;

uses

Forms,

Unit1 in 'Unit1.pas' {Form1};

{$R *.res}

begin

Application.Initialize;

Application.CreateForm(TForm1, Form1);

Application.Run;

end.

Svn "Unable to connect to a repository at URL" 错误

1. 今天check out项目的时候，svn突然报了一个如下错误：

Checkout from http://127.0.0.1/financing, revision HEAD, Fully recursive, Externals included
Unable to connect to a repository at URL 'http://127.0.0.1/financing'
The OPTIONS request returned invalid XML in the response: XML parse error at
 line 1: no element found (http://127.0.0.1/financing)

Checkout from http://127.0.0.1/financing, revision HEAD, Fully recursive, Externals included

Unable to connect to a repository at URL 'http://127.0.0.1/financing'

The OPTIONS request returned invalid XML in the response: XML parse error at

line 1: no element found (http://127.0.0.1/financing)

在网上查了一上解决办法为：

在地址和项目名称之间加上svn，本例中为如下：http://127.0.0.1/svn/financing，再进行check out就没问题了

Listview实现移动功能

分类：Other 阅读 (2,218) No Responses »

在Delphi的ListView中实现向上移动或者向下移动某行的功能，代码如下：

procedure TForm1.ExchangeItem(lv: TListView; const iFrom, iTo: Integer);
var
  tempItem: TListItem;
begin
  if iFrom = iTo then Exit;
  if (iTo < 0) or (iTo >= lv.Items.Count) then Exit;

  lv.Items.BeginUpdate;
  try
    tempItem := TListItem.Create(lv.Items);
    tempItem.Assign(lv.Items.Item[iFrom]);
    lv.Items.Item[iFrom].Assign(lv.Items.Item[iTo]);
    lv.Items.Item[iTo].Assign(tempItem);
    lv.ItemIndex := lv.Items[iTo].Index;
    tempItem.Free;
  finally
    lv.Items.EndUpdate
  end;
end;

procedure TForm1.btnMoveDownClick(Sender: TObject);
begin
  ExchangeItem(lvSE, lvSE.Selected.Index,  lvSE.Selected.Index + 1);
end;

procedure TForm1.btnMoveUpClick(Sender: TObject);
begin
  ExchangeItem(lvSE, lvSE.Selected.Index,  lvSE.Selected.Index - 1);
end;

procedure TForm1.ExchangeItem(lv: TListView; const iFrom, iTo: Integer);

var

tempItem: TListItem;

begin

if iFrom = iTo then Exit;

if (iTo < 0) or (iTo >= lv.Items.Count) then Exit;

lv.Items.BeginUpdate;

try

tempItem := TListItem.Create(lv.Items);

tempItem.Assign(lv.Items.Item[iFrom]);

lv.Items.Item[iFrom].Assign(lv.Items.Item[iTo]);

lv.Items.Item[iTo].Assign(tempItem);

lv.ItemIndex := lv.Items[iTo].Index;

tempItem.Free;

finally

lv.Items.EndUpdate

end;

procedure TForm1.btnMoveDownClick(Sender: TObject);

begin

ExchangeItem(lvSE, lvSE.Selected.Index, lvSE.Selected.Index + 1);

end;

procedure TForm1.btnMoveUpClick(Sender: TObject);

begin

ExchangeItem(lvSE, lvSE.Selected.Index, lvSE.Selected.Index - 1);

end;

XML的NodeName的特殊值

分类：Other 阅读 (2,562) 1 Response »

今天写一个用Java读取XML文件的代码的时候，突然在for循环里发现NodeName=#text的情况，翻来覆去的看XML并没有发现有NodeName为#text的节点。GG了一下才发现原来XML的NodeName并不只是按“<”右边的节点名来定义的，在W3C的文档中还定义了一些特殊的NodeName。

下面先看一下W3C文档中对NodeName的定义

Interface	`nodeName`
`Element`	The tag name, eg. `HTML`
`Attr`	The attribute name, eg. `id`
`Text`	`#text`
`CDATASection`	`#cdata-section`
`EntityReference`	The name of the entity reference, eg. `amp`
`Entity`	The entity name, eg. `&`
`ProcessingInstruction`	The target of the processing instruction, eg.`xml-stylesheet`
`Comment`	`#comment`
`Document`	`#document`
`DocumentType`	The name of the document type, eg. `html`
`DocumentFragment`	`#document-fragment`
`Notation`	The notation name

本人今天使用的XML如下：

<?xml version="1.0" encoding="utf-8"?>
<UserList>
  <User Name="Liu" ID="1">
    <Website><![CDATA[http://svn1.bcoder.com]]></Website>
    <Intro>I come from hebei.</Intro>
  </User>
  <User Name="Zhang" ID="2">
    <Website><![CDATA[http://www.desktoptool.net]]></Website>
    <Intro>I come from Shandong.</Intro>
  </User>
</UserList>

<?xml version="1.0" encoding="utf-8"?>

<Intro>I come from hebei.</Intro>

</User>

<Intro>I come from Shandong.</Intro>

</User>

</UserList>

在两个<User..>的前面各有一个#text类型的Node，乍一看什么都没有啊？其实<UserList>和下行的<User…>之间是有一堆的空格的，于是这堆空格就被当成了#text类型。将XML改成如下样子后就没有那两个#text类型的Node了

<?xml version="1.0" encoding="utf-8"?>
<UserList><User Name="Liu" ID="1">
    <Website><![CDATA[http://svn1.bcoder.com]]></Website>
    <Intro>I come from hebei.</Intro>
  </User><User Name="Zhang" ID="2">
    <Website><![CDATA[http://www.desktoptool.net]]></Website>
    <Intro>I come from Shandong.</Intro>
  </User>
</UserList>

<?xml version="1.0" encoding="utf-8"?>

<Intro>I come from hebei.</Intro>

</User><User Name="Zhang" ID="2">

<Intro>I come from Shandong.</Intro>

</User>

</UserList>

现在也明白为什么有的地方会用如下的判断节点类型的代码了

for (int i=0; i<uNodeList.getLength()- 1; i++){
  if (uNodeList.item(i).getNodeType() == Node.DOCUMENT_TYPE_NODE){
    //...
  }
}

for (int i=0; i<uNodeList.getLength()- 1; i++){

if (uNodeList.item(i).getNodeType() == Node.DOCUMENT_TYPE_NODE){

//...

}

Html特殊字符编码表

1. HTML码都以&开始并以;结尾

2. 记住一些字符的英语全拼可以方便记住这些符号，比如：< lt 为less than, > gt 为greater than, 空格 nbsp为Non-breaking Space
