httpcontent

We are building a highly concurrent web application, and recently we have started using asynchronous programming extensively (using TPL and async / await ). We have a distributed environment, in which apps communicate with each other through REST APIs (built on top of ASP.NET Web API). In one specific app, we have a DelegatingHandler that after calling base.SendAsync (i.e., after calculating the response) logs the response to a file. We include the response's basic information in the log (status code, headers and content): public static string SerializeResponse(HttpResponseMessage response) {

TL;DR -- How do I send a JSON string to a REST host with an auth header? I've tried 3 different approaches found one that works with anonymous types. Why can't I use anonymous types? I need to set a variable called "Group-Name", and a hyphen isn't a valid C# identifier. Background I need to POST JSON but am unable to get the body and the content type correct Function #1 - Works with anonymous types The content type and data is correct, but I don't want to use anonymous types. I want to use a string static void PostData(string restURLBase, string RESTUrl, string AuthToken, string postBody) {

I have an ASP.NET Web API hosted and can access http get requests just fine, I now need to pass a couple of parameters to a PostAsync request like so: var param = Newtonsoft.Json.JsonConvert.SerializeObject(new { id=_id, code = _code }); HttpContent contentPost = new StringContent(param, Encoding.UTF8, "application/json"); var response = client.PostAsync(string.Format("api/inventory/getinventorybylocationidandcode"), contentPost).Result; This call is returning a 404 Not Found result. The server side API action looks like so: [HttpPost] public List<ItemInLocationModel>

So, I created a HttpClient and am posting data using HttpClient.PostAsync() . I set the HttpContent using HttpContent content = new FormUrlEncodedContent(post_parameters) ; where post_parameters is a list of Key value pairs List<KeyValuePair<string, string>> Problem is, when the HttpContent has a large value (an image converted to base64 to be transmitted) I get a URL is too long error. That makes sense - cause the url cant go beyond 32,000 characters. But how do I add the data into the HttpContent if not this way? Please help. I figured it out with the help of my friend. What you would want

How can I read the contents on the PUT request in MVC webApi controller action. [HttpPut] public HttpResponseMessage Put(int accountId, Contact contact) { var httpContent = Request.Content; var asyncContent = httpContent.ReadAsStringAsync().Result; ... I get empty string here :( What I need to do is: figure out "what properties" were modified/sent in the initial request (meaning that if the Contact object has 10 properties, and I want to update only 2 of them, I send and object with only two properties, something like this: { "FirstName": null, "LastName": null, "id": 21 } The expected end

I see in tons of examples on the web using the new HttpClient object (as part of the new Web API) that there should be HttpContent.ReadAsAsync<T> method. However, MSDN doesn't mention this method, nor does IntelliSense find it. Where did it go, and how do I work around it? J... It looks like it is an extension method (in System.Net.Http.Formatting): HttpContentExtensions Class Update: PM> install-package Microsoft.AspNet.WebApi.Client According to the System.Net.Http.Formatting NuGet package page, the System.Net.Http.Formatting package is now legacy and can instead be found in the Microsoft

public static async Task<string> GetData(string url, string data) { UriBuilder fullUri = new UriBuilder(url); if (!string.IsNullOrEmpty(data)) fullUri.Query = data; HttpClient client = new HttpClient(); HttpResponseMessage response = await client.PostAsync(new Uri(url), /*expects HttpContent*/); response.Content.Headers.ContentType = new MediaTypeHeaderValue("application/json"); response.EnsureSuccessStatusCode(); string responseBody = await response.Content.ReadAsStringAsync(); return responseBody; } The PostAsync takes another parameter that needs to be HttpContent .
