How to send HTTP POST message in ASP.NET Core using HttpClient Post as Json Async?
Student
I am Utpal Vishwas from Uttar Pradesh. Have completed my B. Tech. course from MNNIT campus Prayagraj in 2022. I have good knowledge of computer networking.
Sure, here is the code to send an HTTP POST message in ASP.NET Core using HttpClient.PostAsJsonAsync:
C#
This code will first create a
HttpClientinstance. Then, it will create a JSON object to send as the request body. The JSON object will contain aNameproperty and anAgeproperty. TheNameproperty will be set to "John Doe" and theAgeproperty will be set to 30.Next, the code will serialize the JSON object to a string. The string will be encoded as UTF-8 and the content type will be set to "application/json".
Finally, the code will send the POST request to the specified URL. The response status code will be checked to determine if the request was successful. If the request was successful, the code will do nothing. Otherwise, the code will print an error message.
To run this code, you will need to install the
Microsoft.AspNetCore.Http NuGet package. You can do this by opening the Package Manager Console in Visual Studio and running the following command:Code snippet
Once the package is installed, you can run the code by pressing
F5in Visual Studio.
