Delphi之线程

function TMyThread.ExecTimer: Boolean;
begin
Result := False ;
FMyThreadExecfinish := False;
Screen.Cursor := crHourGlass;
CoInitialize(nil); // 一定要加上此行代码
try
    TranspondClientBaseData_factory1(HTTPRIOLeExp, HTTPRIONC, LogStrings);
    Sleep(1000);
    TranspondPersonBaseData_factory1(HTTPRIOLeExp, HTTPRIONC, LogStrings);
    Sleep(1000);
    TranspondDeptBaseData_factory1(HTTPRIOLeExp, HTTPRIONC, LogStrings);
finally
    Result := True;
    FMyThreadExecfinish := True;
    Screen.Cursor := crDefault;
    CoUninitialize;// 一定要加上此行代码
end;

end;

即必须在使用前初始化COM环境

======最终搞完了，多线程调用Webservice，两种方式，一种是windows的Api，另一种是用thread类

方法1的例子(缺点是只能起一个线程，两个的话地址错误，关闭执行保护也不行)：

1、工程内，File->new->Webservice->WSDLImporter，导入webservice地址，生成一个新的pas，得到输出函数，比如叫GetSvrForPosSoap

2、该pas内切记，在initialization后面加上

InvRegistry.RegisterInvokeOptions(TypeInfo(SvrForPosSoap), ioDocument);//这行要手工加，否则传入参数会为空

3、

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, SOAPHTTPClient, StdCtrls, InvokeRegistry, Rio, ActiveX;
type

  TForm1 = class(TForm)

  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;
implementation
uses
   SvrForPos,XSBuiltIns;
{$R *.dfm}

4、

procedure TForm1.Button1Click(Sender: TObject);
var
  HelloWorld,sMsg:widestring;
  HTTPRIO:THTTPRIO;
begin
  try
    begin
      HTTPRIO := THTTPRIO.Create(Application);
      HTTPRIO.HTTPWebNode.UseUTF8InHeader:=true;  //必须要加，解决中文参数的
      HelloWorld := GetSvrForPosSoap(True,'', HTTPRIO).HelloWorld('Test My Brain,测试！');//调用webservice及其内部函数HelloWorld
      Edit1.Text:=HelloWorld;
    end
  Except
  On E:Exception do
    begin
      sMsg:=E.Message;
      sMsg:='意外失败：'+sMsg;
      showmessage(sMsg);
    end;
  end;
end;

5、

function MyThreadFun(p: Pointer): DWORD; stdcall;
var
  i: Integer;
  HelloWorld,sMsg:widestring;
  HTTPRIO:THTTPRIO;
begin
  coinitialize(nil);  //必须加,否则提示尚水调用
  try
    HTTPRIO := THTTPRIO.Create(Application);
    HTTPRIO.HTTPWebNode.UseUTF8InHeader:=true;
    for i := 0 to 10 do
    begin
      HelloWorld := GetSvrForPosSoap(True,'', HTTPRIO).HelloWorld('Test My Brain,测试！我要测试！');
      form1.ListBox1.Items.Add(IntToStr(i)+'  '+HelloWorld);
    end;
  finally
    CoUninitialize;//必须加,否则提示尚水调用
  end;
  //for i := 0 to 99 do form1.ListBox1.Items.Add(IntToStr(i));

  Result := 0;
end;

procedure TForm1.Button3Click(Sender: TObject);
var
  ID: DWORD;
begin
  CreateThread(nil, 0, @MyThreadFun, nil, 0, ID);
end;

方法2的例子(多线程调webservice是可以的)：

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, SOAPHTTPClient, StdCtrls, InvokeRegistry, Rio, ActiveX, ExtCtrls;

type

  TConnDbThread = class(TThread)
  private
    { Private declarations }
  protected
    procedure Execute; override;
  end;

  TForm1 = class(TForm)
    Button1: TButton;
    Edit1: TEdit;
    Edit2: TEdit;
    Button2: TButton;
    ListBox1: TListBox;
    Button3: TButton;
    Timer1: TTimer;
    procedure Button1Click(Sender: TObject);
    procedure Button2Click(Sender: TObject);
    procedure Button3Click(Sender: TObject);
    procedure FormCreate(Sender: TObject);
    procedure Timer1Timer(Sender: TObject);
  private
    { Private declarations }
    Threads, Threads1: TConnDbThread;
  public
    { Public declarations }
  end;

var
  Form1: TForm1;
implementation
uses
   SvrForPos,XSBuiltIns;
{$R *.dfm}procedure TConnDbThread.Execute;
var
  i: Integer;
  HelloWorld,sMsg:widestring;
  HTTPRIO:THTTPRIO;

  sProcName: WideString;
  sParamName: WideString;
  sParamType: WideString;
  sParamLen: WideString;
  sParamDirection: WideString;
  sParamValue: WideString;
  CallProcedureResult: Boolean;
  sOutParamValue: WideString;
  sResultCode: WideString;
  sMessage: WideString;
  sJson: WideString;
begin

  coinitialize(nil);
  try
    HTTPRIO := THTTPRIO.Create(Application);
    HTTPRIO.HTTPWebNode.UseUTF8InHeader:=true;
    for i := 0 to 10 do
    begin
        sProcName:='sPro_BankCertiStatusCheck';
        sParamName:='ps_CertiNo;ps_CheckCode;pf_CertiMe;ps_OrgCode;ps_SaleNo;ps_CxBillNo;ps_CertiCode;ps_ZfType;ps_BgnDate;ps_EndDate;pf_SjCertiMe;pi_Result;ps_Message';
        sParamType:='S;S;F;S;S;S;S;S;S;S;F;I;S';
        sParamLen:='20;4;19;10;20;20;4;4;10;10;19;-1;2000';
        sParamDirection:='I;I;I;I;I;O;O;O;O;O;O;O;O';
        sParamValue:='123456;1234;50;1008;2014010210080001;*;1;1;1;1;1;1;1';//输出参数随便写啥，但必须写

        GetSvrForPosSoap(True,'', HTTPRIO).CallProcedure(sProcName,sParamName,sParamType,sParamLen,
        sParamDirection,sParamValue,CallProcedureResult,sOutParamValue,sResultCode,sMessage,sJson);
        HelloWorld := sOutParamValue;
        form1.ListBox1.Items.Add(IntToStr(i)+'  '+HelloWorld);

    end;
  finally
    CoUninitialize;
  end;
end;

procedure TForm1.Button3Click(Sender: TObject);
begin
  Threads:=TConnDbThread.Create(False);
  Threads1:=TConnDbThread.Create(False);
end;
