【问题描述】:
我有一个 VisualStudio17 无服务器应用程序项目,并且正在使用 .net core Web Api。
我想确认我的 SNS 订阅,但我遇到了一个问题,即 AWS 发送 POST 请求时标头 content-type 设置为 text/plain; charset=UTF-8 而正文是 JSON。
这是来自documentation 的示例请求:
POST / HTTP/1.1
x-amz-sns-message-type: Notification
x-amz-sns-message-id: da41e39f-ea4d-435a-b922-c6aae3915ebe
x-amz-sns-topic-arn: arn:aws:sns:us-west-2:123456789012:MyTopic
x-amz-sns-subscription-arn: arn:aws:sns:us-west-2:123456789012:MyTopic:2bcfbf39-05c3-41de-beaa-fcfcc21c8f55
Content-Length: 761
Content-Type: text/plain; charset=UTF-8
Host: ec2-50-17-44-49.compute-1.amazonaws.com
Connection: Keep-Alive
User-Agent: Amazon Simple Notification Service Agent
{
"Type" : "Notification",
"MessageId" : "da41e39f-ea4d-435a-b922-c6aae3915ebe",
"TopicArn" : "arn:aws:sns:us-west-2:123456789012:MyTopic",
"Subject" : "test",
"Message" : "test message",
"Timestamp" : "2012-04-25T21:49:25.719Z",
"SignatureVersion" : "1",
"Signature" : "EXAMPLElDMXvB8r9R83tGoNn0ecwd5UjllzsvSvbItzfaMpN2nk5HVSw7XnOn/49IkxDKz8YrlH2qJXj2iZB0Zo2O71c4qQk1fMUDi3LGpij7RCW7AW9vYYsSqIKRnFS94ilu7NFhUzLiieYr4BKHpdTmdD6c0esKEYBpabxDSc=",
"SigningCertURL" : "https://sns.us-west-2.amazonaws.com/SimpleNotificationService-f3ecfb7224c7233fe7bb5f59f96de52f.pem",
"UnsubscribeURL" : "https://sns.us-west-2.amazonaws.com/?Action=Unsubscribe&SubscriptionArn=arn:aws:sns:us-west-2:123456789012:MyTopic:2bcfbf39-05c3-41de-beaa-fcfcc21c8f55"
}
内容类型:文本、正文 JSON。这使得它解析起来相当困难,而且一个简单的
public void Post([FromBody] string t) // or dynamic t for the matter
不起作用并抛出Request was short circuited at action filter 'Microsoft.AspNetCore.Mvc.ModelBinding.UnsupportedContentTypeFilter'. 异常。
我错过了什么吗?他们为什么要这样做,我该如何处理?
