webclient in autohotkey [英] Webclient in autohotkey

问题描述

这有效：

This works:

URLDownloadToFile, https://www.nseindia.com/content/historical/EQUITIES/2016/JAN/cm01JAN2016bhav.csv.zip, C:\Users\Dave\Desktop\Happy.zip

但我不明白为什么即使URL语法或格式相同也不会这样：

But I donot understand why this does not even if the URL syntax or format is same:

URLDownloadToFile, https://www.nseindia.com/content/historical/EQUITIES/2015/DEC/cm31DEC2015bhav.csv.zip, C:\Users\Dave\Desktop\Sad.zip

我的尝试：



我发现以下用C＃编写的方法来自 social.msdn 但我的AHK技能非常有限。你能帮忙将下面的C＃转换成AHK吗？

What I have tried:

I found the below method written in C# from social.msdn for the same issue but my AHK skills are very limited. Could you help convert the below C# to AHK?

WebClient objWebClient = new WebClient();
Uri uriWebClient = new Uri(url);
objWebClient.Headers.Add("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)");
objWebClient.Headers.Add("Content-Type", "application / zip, application / octet - stream");
objWebClient.Headers.Add("Accept-Encoding", "gzip,deflate,sdch");
objWebClient.Headers.Add("Referer", "http://Something");
objWebClient.Headers.Add("Accept","text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8");
objWebClient.DownloadFile(uriWebClient, filepath);

推荐答案

因为第二个URL返回 403：禁止。



响应状态意味着即使您通过了身份验证，也不允许您下载该文件。

HTTP 403 - 维基百科 [ ^ ]



编辑：看起来服务器正在验证引荐来源标头。将其更改为：

Because the second URL returns 403: Forbidden.

That response status means you are not allowed to download that file, even if you were authenticated.

HTTP 403 - Wikipedia[^]

Looks like the server is validating the referrer header. Change it to:

objWebClient.Headers.Add("Referer", "https://www.nseindia.com/products/content/equities/equities/archieve_eq.htm");

谢谢Richard，
