[delphi]indy10 idhttp get方法

idhttp中对于get方法的定义：

[delphi] view
plaincopyprint?

procedure Get(AURL: string; AResponseContent: TStream); overload;

procedure Get(AURL: string; AResponseContent: TStream; AIgnoreReplies: array of SmallInt);

overload;

function Get(AURL: string): string; overload;

function Get(AURL: string; AIgnoreReplies: array of SmallInt): string; overload;

其中的最基本的方法是过程类方法

[delphi] view
plaincopyprint?

procedure Get(AURL: string; AResponseContent: TStream; AIgnoreReplies: array of SmallInt);

overload;

其他的几个get方法重载都是基于嵌套的此方法。

参数：

[python] view
plaincopyprint?

AURL: string; // get操作的目标URL

AResponseContent: TStream; // 返回流

AIgnoreReplies: array of SmallInt; // 忽略掉出现这些http状态码的错误

示例代码：

[delphi] view
plaincopyprint?

unit UMain;
