Using HttpResponseMessage response = await httpClient.PutAsync( To make an HTTP PUT request, given an HttpClient and a URI, use the HttpClient.PutAsync method: static async Task PutAsync(HttpClient httpClient) The PUT request method either replaces an existing resource or creates a new one using request body payload. Deserializes the response body into a Todo instance, and writes the Todo to the console.Ensures that the response is successful, and writes the request details to the console.Serializes the Todo instance as JSON, and makes a POST request to "".Internal static void WriteRequestToConsole(this HttpResponseMessage response)Ĭonsole.Write($" The WriteRequestToConsole is a custom extension method that isn't part of the framework, but if you're curious about how it's implemented, consider the following C# code: static class HttpResponseMessageExtensions Writes the JSON response body to the console.Writes the request details to the console.Ensures that the response is successful.Using HttpResponseMessage response = await httpClient.GetAsync("todos/3") To make an HTTP GET request, given an HttpClient and a URI, use the HttpClient.GetAsync method: static async Task GetAsync(HttpClient httpClient) HTTP GetĪ GET request shouldn't send a body and is used (as the method name indicates) to retrieve (or get) data from a resource. The HttpContent class is also used to represent the response body of the HttpResponseMessage, accessible on the HttpResponseMessage.Content property. StringContent: Provides HTTP content based on a string.StreamContent: Provides HTTP content based on a stream.ReadOnlyMemor圜ontent: Provides HTTP content based on a ReadOnlyMemory.MultipartFormDataContent: Provides a container for content encoded using "multipart/form-data" MIME type.MultipartContent: Provides a collection of HttpContent objects that get serialized using the "multipart/*" MIME type specification.JsonContent: Provides HTTP content based on JSON.FormUrlEncodedContent: Provides HTTP content for name/value tuples encoded using "application/x-www-form-urlencoded" MIME type.ByteArra圜ontent: Provides HTTP content based on a byte array.Most examples show how to prepare the StringContent subclass with a JSON payload, but other subclasses exist for different content (MIME) types. For HTTP methods (or request methods) that require a body, POST, PUT, and PATCH, you use the HttpContent class to specify the body of the request. The HttpContent type is used to represent an HTTP entity body and corresponding content headers. While there is a synchronous HttpClient.Send method, it is recommended to use the asynchronous APIs instead, unless you have good reason not to. Making HTTP requests is considered network I/O-bound work. Applying a nondefault HttpClient.Timeout.Setting HttpClient.DefaultRequestHeaders.This HttpClient instance uses the base address when making subsequent requests. As per the guidelines, it's recommended to reuse HttpClient instances during the application's lifecycle. Instantiates a new HttpClient instance as a static variable.Private static HttpClient sharedClient = new() HttpClient lifecycle management best practices: For more information, see Guidelines for using HttpClient. To create an HttpClient, use the HttpClient class constructor. Most of the following examples reuse the same HttpClient instance, and therefore only need to be configured once.
