如何使用http发布上传文件？德尔福2009 [英] How do I upload a file using http post? Delphi 2009

问题描述

我的目标是通过HTTP帖子上传文本文件，而我正在使用Delphi 2009。

My goal is to upload a text file via HTTP post I am using Delphi 2009.

例如说到以下URL

https://www.example.com/ex/exampleAPI.asmx/Process

我知道可以使用TIdHttp组件来完成。接下来的调用

I understand it can be done by using the TIdHttp component. And the following call

IdHttp1.Post();

但是我不知道如何设置所有内容，即指定url并包括要发布的文件。

But I cant figure out how to set up everything i.e. specifying the url and including the file to be posted.

谢谢。

推荐答案

TIdHTTP 有两个 Post（）的重载版本，它们以文件名作为输入：

TIdHTTP has two overloaded versions of Post() that take a filename as input:

var
  Response: String;

Response := IdHTTP1.Post('https://www.example.com/ex/exampleAPI.asmx/Process', 'c:\filename.txt');

。

var
  Response: TStream;

Response := TMemoryStream.Create;
IdHTTP1.Post('https://www.example.com/ex/exampleAPI.asmx/Process', 'c:\filename.txt', Response);
...
Response.Free;

请注意，您要发布到 HTTPS URL，因此您需要先将启用SSL的IOHandler（例如 TIdSSLIOHandlerSocketOpenSSL ）分配给 TIdHTTP.IOHandler 属性

Note that you are posting to an HTTPS URL, so you need to first assign an SSL-enabled IOHandler, such as TIdSSLIOHandlerSocketOpenSSL, to the TIdHTTP.IOHandler property beforehand.
