Delphi 7 ISAPI WebBroker文件上传 [英] Delphi 7 ISAPI WebBroker file upload

问题描述

我正在尝试在Delphi 7 Webbroker CGI中接受文件上传。

I am trying to accept file uploads in a Delphi 7 Webbroker CGI.

我正在使用Shiv Kumar的TMsMultipartParser，但Chrome出现问题。我无法访问已解析的数据（令人惊讶的是，资源管理器工作正常）。

I'm using Shiv Kumar's TMsMultipartParser, but I have a problem with Chrome. I can't access the parsed data (surprisingly, Explorer works fine).

这是我的代码：

with TMsMultipartFormParser.Create do
begin
    Parse(Request);

    lsExternalID:=ContentFields.Values['external_id'];

    if (lsExternalID='') then
        raise Exception.Create('No external ID');

    for i := 0 to Files.Count -1 do
    begin
        lsFileName:=files[i].FileName;
        //Rename file using external ID (not included for simplicity)
        Files[i].SaveToFile(lsFilename);
    end;
    Response.Content := 'OK';
    free;
end;

如建议在此处，我尝试使用 http://www.mrsoft.org/Delphi/MultipartParser .pas ，但我无法编译。它使用了一个我在任何地方都找不到的名为UniversalUtils的单元。

As suggested here, I tried to use http://www.mrsoft.org/Delphi/MultipartParser.pas but I can't compile it. It uses a unit called UniversalUtils that I can't find anywhere.

我知道这是一种非常过时的技术。几乎所有对它的引用都已从网上消失（相信我，我已经搜索过）。

I know this is a very obsolete technology. Almost all references to it have already disappeared from the web (believe me, I have searched). Buy any help would be deeply appreciated.

谢谢。

推荐答案

终于有了@mrabat，我终于解决了我的问题。
该项目始于Delphi5。后来被升级为Delphi 7（由于许多部分不支持Unicode字符串，因此无法使用，因此我们使用ANSI）。
我们使用Shiv的TMsMultipartParser是因为Delphi 5没有包含任何解析器。
Delphi 7在ReqMulti.pas单元中具有TMultipartContentParser，它可以正常工作。

I finally solved my problem, thanks to @mrabat. This project started in Delphi 5. It was later upgraded to Delphi 7 (it can't be upgraded further, because many parts can't support Unicode strings, we use ANSI). We were using Shiv's TMsMultipartParser because Delphi 5 didn't have any parser included. Delphi 7 has TMultipartContentParser in unit ReqMulti.pas, and it works perfectly.

对于需要示例的任何人，我都会发布我的工作代码：

For anyone that need an example, I'll post my working code:

with TMultipartContentParser.Create(Request) do
begin
    lsExternalID:=ContentFields.Values['external_id'];
    if (lsExternalID='') then
        raise Exception.Create('No external ID');

    for i := 0 to Request.Files.Count -1 do
    begin
        lsFileName:=Request.Files[i].FileName;
        //Rename file using external ID (not included for simplicity)
        TMemoryStream(Request.Files[i].Stream).SaveToFile(lsFilename);
    end;
    Response.Content := 'OK';
    Free;
end;
