我有一个VisualStudio17无服务器应用程序项目,并且正在使用核心Web Api。
I have a VisualStudio17 serverless application project and am using core Web Api.
我想确认我的SNS订阅,但是我遇到一个问题,即AWS发送标头 content-type 设置为文本/纯文本; charset = UTF-8 而body为JSON。
I want to confirm my SNS subscription, but I have a problem that AWS sends the POST request with header content-type set to text/plain; charset=UTF-8 while body is JSON.
以下是他们的文档:
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: ec2-50-17-44-49pute-1.amazonaws 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" : "sns.us-west-2.amazonaws/SimpleNotificationService-f3ecfb7224c7233fe7bb5f59f96de52f.pem", "UnsubscribeURL" : "sns.us-west-2.amazonaws/?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。这使得解析非常困难,并且简单的
Content-type: text, body JSON. This makes it parsing quite difficult, and a simple

public void Post([FromBody] string t) // or dynamic t for the matter
不起作用并抛出请求在操作筛选器'Microsoft.AspNetCore.Mvc.ModelBinding中短路。 异常。
我错过了什么吗?他们为什么这样做,我该如何处理?
Am I missing something? Why are they doing this and how do I work with this?
推荐答案我按照此答案,方法是将 text / plain 添加到 JsonInputFormatter 应该格式化的格式。
I made it work like I described in this answer, by adding text/plain to formats that JsonInputFormatter should format.
public void ConfigureServices(IServiceCollection services) { services.AddMvc(config => { foreach (var formatter in config.InputFormatters) { if (formatter.GetType() == typeof(JsonInputFormatter)) ((JsonInputFormatter)formatter).SupportedMediaTypes.Add( MediaTypeHeaderValue.Parse("text/plain")); } }); ... }更多推荐
