WebClient hangs until timeout

房东的猫 提交于 2019-12-02 09:04:49
问题 I try do download a web page using the WebClient, but it hangs until the timeout in WebClient is reached, and then fails with an Exception. The following code will not work WebClient client = new WebClient(); string url = "https://www.nasdaq.com/de/symbol/aapl/dividend-history"; string page = client.DownloadString(url); Using a different URL, the transfer works fine. For example WebClient client = new WebClient(); string url = "https://www.ariva.de/apple-aktie"; string page = client

My app targets Windows CE; it uses the Compact Framework I copied over some elsewhere-working code that uses WebClient, but it won't compile, saying, " The type or namespace name 'WebClient' could not be found (are you missing a using directive or an assembly reference?) " I do have a "using System.Net;" Because of that error, I also get, " The name 'HttpRequestHeader' does not exist in the current context " The code is: private static void SendXMLFile(string xmlFilepath, string uri) { using (var client = new WebClient()) { client.Headers[HttpRequestHeader.ContentType] = "application/x-www

I'm having trouble downloading the file, here's the link: http://vsbg023.cda.pl/apple/13801451161599.mp4?st=zFHkNA18rmxan4AvOQWRmw&e=1431286721 (This is just an example) As soon as the WebClient tries to download it, it raises the exception "The remote server returned an error ( 403 ) forbidden" I searched in google, I only found this: http://pastebin.com/arU4WtC7 But nothing gives this error, sometimes it starts to download, but only for a while and the program is suspended, even though the file is still downloading. Maybe someone knows how to fix it? You can download the code here: http:/

How to ensure that webclient/curl process 503 error like they process 200

天涯浪子 提交于 2019-12-02 04:10:30
问题 If website pops out a 503 then webclient will just throw an exception. For example, go to http://www.google.com/sorry/?continue=http%3A%2F%2Fwww.google.com%2Fsearch%3Fq%3Dkucing If we open it in internet explorer it'll open a page. If we use livehttpheader it returns a 503 rather than 200. However, it still show something. Now try curl the same page. http://www.google.com/sorry/?continue=http%3A%2F%2Fwww.google.com%2Fsearch%3Fq%3Dkucing The curl will just stop failing. So how to make curl
