上傳文件 IFormFile 到 Azure C# function

Question

我有這個常規的 C# Azure function：

[FunctionName("Function1")]
public static async Task<IActionResult> Run(
    [HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req,
    ILogger log) ...

我需要在這里上傳文件，例如圖片。 如何在此處添加IFormFile或有其他方式將文件上傳到 function？

Answer 1

要將文件上傳到 Azure Function，請查看傳入HttpRequest的表單。

這對我有用：

public static async Task<IActionResult> Run(
    [HttpTrigger(AuthorizationLevel.Anonymous, "post", Route = "files")] HttpRequest req,
    ILogger log)
{
    foreach(var file in req.Form.Files)
    {
        using (var ms = new MemoryStream())
        {
            var file = req.Form.Files[0];
            await file.CopyToAsync(ms);
            ms.Seek(0, SeekOrigin.Begin);
            // Do something with the file
        }
    }

    return new OkResult();
}
