我使用json.net在IIS托管的restful服务中执行处理我的json反序列化。
首先,这是我尝试使用的对象。
[DataContract]
public class CreateSamplesRequest
{
[DataMember] public Guid SessionId { get; set; }
[DataMember] public SampleTemplateDTO Template { get; set; }
}
[DataContract]
public class SampleTemplateDTO
{
[DataMember] public int NumberOfSamples { get; set; }
[DataMember] public int CompanyId { get; set; }
[DataMember] public int SampleTypeId { get; set; }
[DataMember] public HmisDTO Hmis { get; set; }
[DataMember] public List<AttributeValueDTO> AttributeValues { get; set; }
}
[DataContract]
public class AttributeValueDTO
{
[DataMember] public int AttributeId { get; set; }
[DataMember] public string AttributeName { get; set; }
[DataMember] public string Value { get; set; }
}
[DataContract]
public class HmisDTO
{
[DataMember] public string Health { get; set; }
[DataMember] public string Flammability { get; set; }
[DataMember] public string Reactivity { get; set; }
[DataMember] public string Equipment { get; set; }
}
帮助页面以CreateZamplesRequest
的格式请求json{
"SessionId":"1627aea5-8e0a-4371-9022-9b504344e724",
"Template":{
"NumberOfSamples":2147483647,
"CompanyId":2147483647,
"SampleTypeId":2147483647,
"Hmis":{
"Health":"String content",
"Flammability":"String content",
"Reactivity":"String content",
"Equipment":"String content"
},
"AttributeValues":[{
"AttributeId":2147483647,
"AttributeName":"String content",
"Value":"String content"
}]
}
}
这就是我实际发送的内容:
{
"SessionId":"17aaec11-be28-4536-b5df-d98fbda91e91",
"Template":{
"NumberOfSamples":1,
"CompanyId":1,
"SampleTypeId":9,
"Hmis":{
"Health":"2",
"Flammability":"0",
"Reactivity":"0",
"Equipment":"E",
},
"AttributeValues":[
{"AttributeId":1,"AttributeName":"Item No.","Value":"MN0002NG"},
{"AttributeId":2,"AttributeName":"Lot No.","Value":"C4526"}
]
}
}
我遇到的问题是SampleTemplateDTO对象的AttributeValues属性总是被忽略。使用上面的代码,它将为null。如果我将它实例化为空List<AttributeValueDTO>
,它将是一个空列表。几个小时后我一直在敲打着我。
我尝试创建一个只需List<AttributeValueDTO>
的服务,但它运行正常。我尝试为AttributeValues创建一个包装类,它仍然以null结尾。我完全难过了。有什么想法吗?
答案 0 :(得分:6)
上帝的母亲,我只是浪费了5小时的爆发力。 HMIS部分中的尾随逗号显然告诉json.net在此时停止解析。
当我提交这个json:
{
"SessionId":"17aaec11-be28-4536-b5df-d98fbda91e91",
"Template":{
"NumberOfSamples":1,
"CompanyId":1,
"SampleTypeId":9,
"Hmis":{
"Health":"2",
"Flammability":"0",
"Reactivity":"0",
"Equipment":"E"
},
"AttributeValues":[
{"AttributeId":1,"AttributeName":"Item No.","Value":"MN0002NG"},
{"AttributeId":2,"AttributeName":"Lot No.","Value":"C4526"}
]
}
}
一切都很好。
