Question

我有一个web api方法，如下所示：

[HttpPost]
[Route("messages")]
public IHttpActionResult Post(IEnumerable<Email> email)
{
    AddToQueue(email);
    return Ok("message added to queue");
}

我的电子邮件类目前看起来像这样：

public string Body { get; set; }
public string From { get; set; }
public string Template { get; set; }
public string To { get; set; }        
public string Type { get; set; }

我正在使用fiddler发布到我的Post方法，如下所示：

User-Agent: Fiddler
Host: localhost:3994
Content-Length: 215
Content-Type: application/json; charset=utf-8
[
{"Body":"body","From":"from","To":"to","Template":"template"},
{"Body":"body1","From":"from1","To":"to1","Template":"template1"},
{"Body":"body2","From":"from2","To":"to2","Template":"template2"}
]

这很好用。但是，我希望能够将Dictionary添加到我的Email类中，所以它看起来像这样：

public string Body { get; set; }
public string From { get; set; }
public string Template { get; set; }
public string To { get; set; }        
public string Type { get; set; }
public Dictionary<string, string> HandleBars { get; set; }

我改变了我的要求：

[{
   "Body": "body",
   "From": "from",
   "To": "to",
   "Template": "template",
   "HandleBars": [{
      "something": "value"
    }]
}, 
{
   "Body": "body1",
   "From": "from1",
   "To": "to1",
   "Template": "template1"
 }, 
 {
   "Body": "body2",
   "From": "from2",
   "To": "to2",
   "Template": "template2"
 }]

但是，当Post方法收到此消息时，将填充所有电子邮件字段，但HandleBars字典除外。为了正确传递，我该怎么办？我的json结构不正确吗？

Answer 1

默认JsonFormatter无法绑定来自Javascript Dictionary的{{1}}，因为它没有为每个项目定义键。

您需要使用Array代替：

Object

Answer 2

你应该

{
   "Body": "body",
   "From": "from",
   "To": "to",
   "Template": "template",
   "HandleBars": [
        { key: 'key1', value: 'something'}
    ]
}
