问题描述
我有后端端点Task<ActionResult> Post(IFormFile csvFile)
,我需要从HttpClient调用此端点.目前,我正在获取Unsupported media type error
.
这是我的代码:
I have backend endpoint Task<ActionResult> Post(IFormFile csvFile)
and I need to call this endpoint from HttpClient. Currently I am getting Unsupported media type error
.
Here is my code:
var filePath = Path.Combine("IntegrationTests", "file.csv");
var gg = File.ReadAllBytes(filePath);
var byteArrayContent = new ByteArrayContent(gg);
var postResponse = await _client.PostAsync("offers", new MultipartFormDataContent
{
{byteArrayContent }
});
推荐答案
您需要在MultipartFormDataContent
集合中指定匹配动作参数名称(csvFile
)的参数名称和随机文件名
You need to specify parameter name in MultipartFormDataContent
collection matching action parameter name (csvFile
) and a random file name
var multipartContent = new MultipartFormDataContent();
multipartContent.Add(byteArrayContent, "csvFile", "filename");
var postResponse = await _client.PostAsync("offers", multipartContent);
或同等
var postResponse = await _client.PostAsync("offers", new MultipartFormDataContent {
{ byteArrayContent, "csvFile", "filename" }
});
