[delphi]indy idhttp post方法

idhttp中对于post方法的定义:
[delphi] view plaincopyprint?
- function Post(AURL: string; ASource: TIdStrings): string; overload;
- function Post(AURL: string; ASource: TStream): string; overload;
- function Post(AURL: string; ASource: TIdMultiPartFormDataStream): string; overload;
- procedure Post(AURL: string; ASource: TIdMultiPartFormDataStream; AResponseContent: TStream); overload;
- procedure Post(AURL: string; ASource: TIdStrings; AResponseContent: TStream); overload;
- procedure Post(AURL: string; ASource, AResponseContent: TStream); overload;
其中的基本方法是下面的过程类方法,其他post重载方法均为嵌套使用此方法:
[delphi] view plaincopyprint?
- procedure TIdCustomHTTP.Post(AURL: string; ASource, AResponseContent: TStream);
参数:
[delphi] view plaincopyprint?
- AURL: string // post请求URL
- ASource: TIdMultiPartFormDataStream // TStream派生的类,其中为发送的流数据及mime信息,可用于上传文件
- ASource: TStream // 发送的流数据
- AResponseContent: TStream // 响应内容流ASource: TIdStrings // TString派生的类,用于向服务器提交数据
ASource 为TIdStrings的数据,使用的MIME是默认的“application/x-www-form-urlencoded”,而TIdMultiFormDataStream则是根据发送的内容/文件来设定MIME类型。
示例:
[delphi] view plaincopyprint?
- unit Umain;
- interface
- uses
- Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
- Dialogs, IdBaseComponent, IdComponent, IdTCPConnection, IdTCPClient,
