将图像文件从控制台应用程序作为 IFormFile 参数发布到 API [英] Posting image file from console application to API as an IFormFile parameter

问题描述

我需要将图像从 Asp.Net Core 控制台应用程序上传到 API.

I need to upload an image to an API from an Asp.Net Core Console Application.

发布到的 API 看起来像这样并且在使用 Postman 测试时工作正常:

The API being posted to looks like this and works fine when tested with Postman:

[HttpPost("UploadImage")]
public async Task<string> UploadImage(IFormFile files)
{
      // stuff happens here
}

将文件从控制台应用程序发布到该应用程序的代码是什么样的?谢谢

What would the code look like to post a file from the console app to this? Thanks

推荐答案

我需要将图像从 Asp.Net Core 控制台应用程序上传到 API.

I need to upload an image to an API from an Asp.Net Core Console Application.

为了实现从Console app向API后端发送图片的HTTP请求，可以参考下面的代码片段.

To achieve the requirement of making HTTP request to post image from Console app to API backend, you can refer to the following code snippet.

var _httpClient = new HttpClient();

var formContent = new MultipartFormDataContent();

var FilePath = @"D:\xxx\pic1.PNG";

formContent.Add(new StreamContent(File.OpenRead(FilePath)), "files", Path.GetFileName(FilePath));

_httpClient.BaseAddress = new Uri("https://localhost:44312/");

var response = await _httpClient.PostAsync("/UploadImage", formContent);

if (response.IsSuccessStatusCode)
{
    //....
    //code logic here
    //...
}
