爲什麼在MVC託管在Azure中時MultipartFormDataContent不起作用？

Question

我在將表單發佈到MVC時遇到問題，但只有在網站託管在Azure內時纔有問題。當它在本地託管在IIS內部或計算模擬器內部時，它工作正常。

請求已發佈，但是表單中的字段未映射到操作的參數。

是否有什麼我需要做的天藍色部署時髦？

MultipartFormDataContent data = new MultipartFormDataContent(); 
if (!String.IsNullOrEmpty(about)) 
{ 
    data.Add(new StringContent(about), "about"); 
} 
data.Add(new StringContent(displayName), "displayName"); 
data.Add(new StringContent(name), "name"); 
data.Add(new StringContent(email), "email"); 
data.Add(new StringContent(phone), "phone"); 
data.Add(new StringContent(isPublic ? "true": "false"), "isPublic"); 
data.Add(new StringContent(isPrimary ? "true" : "false"), "isPrimaryProfile"); 
if (picture != null) 
{ 
    byte[] imageBytes = await picture.GetBtyeFromFile(); 
    string imageString = Convert.ToBase64String(imageBytes); 
    data.Add(new StringContent(imageString), "picture"); 
} 

Uri uri = new Uri(url, UriKind.Absolute); 
HttpResponseMessage responseMessage = await client.PostAsync(uri, data); 

在服務器端，一切似乎都正確到達。這裏是我拉出InputStream的身體：

Content-Type: text/plain; charset=utf-8 
Content-Disposition: form-data; name=displayName

true 
--614f8827-0cfe-48a6-a819-e6e9acdccae0-- 

，並在標題：

Content-Type: multipart/form-data; boundary="614f8827-0cfe-48a6-a819-e6e9acdccae0"

基本上，你要引用您的PARAM名稱：

data.Add(new StringContent(displayName), @"""displayName""");
