Azure Function HTTP多部分POST无法识别字段

Question

我正试图使用多部分表单发布到web服务。然而，该服务表示无法识别我试图发送的文件上传。这是文件上传的部分。

----WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="file"; filename="GOO1242.pdf"
Content-Type: application/pdf
JVBERi0xLjQKJdP0zOE....... <rest of file>
----WebKitFormBoundary7MA4YWxkTrZu0gW

错误为

{"类型"："validation_error"；，"细节"："没有字段："；文件"}

有什么想法吗？

不确定这是否是您想要的，但我在C#azure函数中使用了RestSharp

var apiRequest = await GetRestRequest(request);
var response = await SendRequest(apiRequest, log);
private async Task<RestRequest> GetRestRequest(string requestInput) 
{
var uploadRequestInput = JsonConvert.DeserializeObject<UploadModelRequest>(requestInput);
var base64EncodedBytes = Convert.FromBase64String(uploadRequestInput.Content);
var uploadBicxRequest = JsonConvert.DeserializeObject<UploadModelRequest>(requestBody);
var apiRequest = new RestRequest("system/archive/document", Method.POST);
apiRequest.AddParameter("key", JsonConvert.SerializeObject(uploadRequest), "application/json", ParameterType.RequestBody);
apiRequest.AddFileBytes("VersionData", base64EncodedBytes, uploadRequest.PathOnClient, "application/octet-stream");
apiRequest.AddHeader("Content-Type", "multipart/form-data");
return apiRequest;
}
