I’ve used HttpClient in .NET 4.0 applications on numerous occasions. If you are familiar with NuGet, you can do an Install-Package Microsoft.Net.Http to add it to your project. See the link below for further details. http://nuget.org/packages/Microsoft.Net.Http
I had a similar problem and had to convert the URL from string to Uri object using: Uri myUri = new Uri(URLInStringFormat, UriKind.Absolute); (URLInStringFormat is your URL) Try to connect using the Uri instead of the string as: WebClient client = new WebClient(); client.OpenRead(myUri);
Use FtpWebRequest, with a method of WebRequestMethods.Ftp.MakeDirectory. For example: using System; using System.Net; class Test { static void Main() { WebRequest request = WebRequest.Create(“ftp://host.com/directory”); request.Method = WebRequestMethods.Ftp.MakeDirectory; request.Credentials = new NetworkCredential(“user”, “pass”); using (var resp = (FtpWebResponse) request.GetResponse()) { Console.WriteLine(resp.StatusCode); } } }
You must subclass and override one or more functions. class MyWebClient : WebClient { protected override WebRequest GetWebRequest(Uri address) { HttpWebRequest request = (HttpWebRequest)base.GetWebRequest(address); request.ClientCertificates.Add(new X509Certificate()); return request; } }
You can do it natively with .Net 4.5+. I tried doing it your way and then I just found a method in Intellisense that seemed to make sense. https://learn.microsoft.com/en-us/dotnet/api/system.io.stream.copytoasync?view=netframework-4.7.2 uri = new Uri(generatePdfsRetrieveUrl + pdfGuid + “.pdf”); HttpClient client = new HttpClient(); var response = await client.GetAsync(uri); using (var fs = new FileStream( HostingEnvironment.MapPath(string.Format(“~/Downloads/{0}.pdf”, pdfGuid)), … Read more
You can continue using WebClient to POST (instead of GET, which is the HTTP verb you’re currently using with DownloadString), but I think you’ll find it easier to work with the (slightly) lower-level classes WebRequest and WebResponse. There are two parts to this – the first is to post the login form, the second is … Read more
for those interested: System.Net.ServicePointManager.DefaultConnectionLimit = x (where x is your desired number of connections) no need for extra references just make sure this is called BEFORE the service point is created as mentioned above in the post.
This worked for me: Create a @Bean in one of your configuration classes or the main SpringBootApplication class: @Bean public WebClient webClient() { final int size = 16 * 1024 * 1024; final ExchangeStrategies strategies = ExchangeStrategies.builder() .codecs(codecs -> codecs.defaultCodecs().maxInMemorySize(size)) .build(); return WebClient.builder() .exchangeStrategies(strategies) .build(); } Next, go to your desired class where you want … Read more
My answer comes from here You can make a derived class, which will set the timeout property of the base WebRequest class: using System; using System.Net; public class WebDownload : WebClient { /// <summary> /// Time in milliseconds /// </summary> public int Timeout { get; set; } public WebDownload() : this(60000) { } public WebDownload(int … Read more
It’s not lying. You should set the webclient’s encoding first before calling DownloadString. using(WebClient webClient = new WebClient()) { webClient.Encoding = Encoding.UTF8; string s = webClient.DownloadString(“http://export.arxiv.org/api/query?search_query=au:Freidel_L*&start=0&max_results=20”); } As for why your alternative isn’t working, it’s because the usage is incorrect. Its should be: System.Text.Encoding.UTF8.GetString()
