HttpClient is more like a head-less browser. It a powerfull and ideal tool if you are going to be creating many http request. For example you can set default headers and stuff. Here are the top 5 ways it differs from an HttpWebRequest which is taken from here An HttpClient instance is the place to … Read more
I wrote the following extension method to clone the request. public static HttpRequestMessage Clone(this HttpRequestMessage req) { HttpRequestMessage clone = new HttpRequestMessage(req.Method, req.RequestUri); clone.Content = req.Content; clone.Version = req.Version; foreach (KeyValuePair<string, object> prop in req.Properties) { clone.Properties.Add(prop); } foreach (KeyValuePair<string, IEnumerable<string>> header in req.Headers) { clone.Headers.TryAddWithoutValidation(header.Key, header.Value); } return clone; }
So it seems like the calling code needs to know about and take ownership of the response message as well as the stream, or I leave the response message undisposed and let the finalizer deal with it. Neither option feels right. In this specific case, there are no finalizers. Neither HttpResponseMessage or HttpRequestMessage implement a … Read more
Besides the tests mentioned in the question, I recently created some new ones involving much fewer HTTP calls (5000 compared to 1 million previously) but on requests that took much longer to execute (500 milliseconds compared to around 1 millisecond previously). Both tester applications, the synchronously multithreaded one (based on HttpWebRequest) and asynchronous I/O one … Read more
Here’s code I’m using to post form information and a csv file using (var httpClient = new HttpClient()) { var surveyBytes = ConvertToByteArray(surveyResponse); httpClient.DefaultRequestHeaders.Add(“X-API-TOKEN”, _apiToken); httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue(“application/json”)); var byteArrayContent = new ByteArrayContent(surveyBytes); byteArrayContent.Headers.ContentType = MediaTypeHeaderValue.Parse(“text/csv”); var response = await httpClient.PostAsync(_importUrl, new MultipartFormDataContent { {new StringContent(surveyId), “\”surveyId\””}, {byteArrayContent, “\”file\””, “\”feedback.csv\””} }); return response; } This is … Read more
WebAPI v2.1 and beyond supports BSON (Binary JSON) out of the box, and even has a MediaTypeFormatter included for it. This means you can post your entire message in binary format. If you want to use it, you’ll need to set it in WebApiConfig: public static class WebApiConfig { public static void Register(HttpConfiguration config) { … Read more
Try: var handler = new HttpClientHandler() { AllowAutoRedirect = false }; HttpClient client = new HttpClient(handler);
I found how to do a “custom” PATCH request with the previous System.Net.Http.HttpClient class here, and then fiddled with until I made it work in the Windows.Web.Http.HttpClient class, like so: public async Task<HttpResponseMessage> PatchAsync(HttpClient client, Uri requestUri, IHttpContent iContent) { var method = new HttpMethod(“PATCH”); var request = new HttpRequestMessage(method, requestUri) { Content = iContent … Read more
but what i am doing is purely synchronous You could use HttpClient for synchronous requests just fine: using (var client = new HttpClient()) { var response = client.GetAsync(“http://google.com”).Result; if (response.IsSuccessStatusCode) { var responseContent = response.Content; // by calling .Result you are synchronously reading the result string responseString = responseContent.ReadAsStringAsync().Result; Console.WriteLine(responseString); } } As far as … Read more
After much trial and error, here’s code that actually works: using (var client = new HttpClient()) { using (var content = new MultipartFormDataContent()) { var values = new[] { new KeyValuePair<string, string>(“Foo”, “Bar”), new KeyValuePair<string, string>(“More”, “Less”), }; foreach (var keyValuePair in values) { content.Add(new StringContent(keyValuePair.Value), keyValuePair.Key); } var fileContent = new ByteArrayContent(System.IO.File.ReadAllBytes(fileName)); fileContent.Headers.ContentDisposition = … Read more
