如何使用delphi在Web上提交表单

Question

如何创建和发布表单，如下面的表格 使用Delphi7 ？

AttributeError: 'A' object has no attribute 'moo' -> Cannot recover attribute 'moo' -> Cannot recover attribute 'F' -> Cannot recover attribute 'G'

Answer 1

Delphi预装了Indy（尽管Delphi 7很老，所以考虑upgrading its Indy to a modern version），它有一个Post()组件。它的Params := TStringList.Create; try Params.Add('TestName=...'); IdHTTP1.Request.Username := ...; IdHTTP1.Request.Password := ...; // set other properties as needed... IdHTTP1.Post('http://www.TestAddress.com/TestPage.php', Params); finally Params.Free; end; 方法有重载版本，用于提交网页表单，例如：

Referer

根据服务器的要求，您可能必须首先请求webform的HTML以获取与其关联的任何cookie，以便它们可以作为webform提交的一部分发送回服务器。或者，如果正在提交的网络表单，您可能需要将// make sure TIdHTTP.AllowCookies is set to True beforehand... IdHTTP1.Get('http://www.TestAddress.com/WebForm.php'); Params := TStringList.Create; try Params.Add('TestName=...'); IdHTTP1.Request.Username := ...; IdHTTP1.Request.Password := ...; // set other properties as needed... IdHTTP1.Request.Referer := 'http://www.TestAddress.com/WebForm.php'; IdHTTP1.Post('http://www.TestAddress.com/TestPage.php', Params); finally Params.Free; end; 请求标头设置为URL：
