C# 在ASP.NETMVC控制器中,如何获得一种方法来识别JSON中的数据并形成URLCoded格式?
我尝试使用ASP.NET代码MVC处理HTTP POST请求,如下所示:C# 在ASP.NETMVC控制器中,如何获得一种方法来识别JSON中的数据并形成URLCoded格式?,c#,json,asp.net-mvc,post,C#,Json,Asp.net Mvc,Post,我尝试使用ASP.NET代码MVC处理HTTP POST请求,如下所示: [Route("coreapi/control")] public class Control : Controller { [HttpPost(userGroups/{groupId}/users/{userId})] public int AddRecord(UserRecord record){ //This even populates the UserId and GroupId
[Route("coreapi/control")]
public class Control : Controller
{
[HttpPost(userGroups/{groupId}/users/{userId})]
public int AddRecord(UserRecord record){
//This even populates the UserId and GroupId fields in record from the route
}
}
上述方法适用于表单URL编码参数,但不适用于JSON
如果我想让JSON工作,我需要使用[FromBody]属性,如下所示:
[Route("coreapi/control")]
public class Control : Controller
{
[HttpPost(userGroups/{groupId}/users/{userId})]
public int AddRecord([FromBody]UserRecord record, int groupId, int userId){
//this doesn't look in the route to populate info anymore
record.GroupId = groupId;
record.UserId = userId;
}
}
如何让这两种方法都在一种方法中工作?因此,这看起来很愚蠢,但从实验和阅读来看,似乎唯一的方法是使用两种不同的方法 一个用于表单编码数据
[Route("coreapi/control")]
public class Control : Controller
{
[HttpPost(userGroups/{groupId}/users/{userId}/add)]
public int AddRecord(UserRecord record){
//This even populates the UserId and GroupId fields in record from the route
}
}
一个用于json:
[Route("coreapi/control")]
public class Control : Controller
{
[HttpPost(userGroups/{groupId}/users/{userId}/addJson)]
public int AddRecordJson([FromBody]UserRecord record, int groupId, int userId){
//this doesn't look in the route to populate info anymore
record.GroupId = groupId;
record.UserId = userId;
}
}
我很好奇当
FromBodyAttribute
丢失时发生了什么,是您得到的错误:参数字典包含参数的空条目
?@Tetsuyayayamamoto,我没有得到错误,但是UserRecord类的所有字段都是空的。发送json字符串时
