post与.net core接受请求参数

标签：core Insert data ctx ClientId public net Type post

///ffff

  const res = await instancs.post(     "Know/DocList_Insert",     {       Id: 1,       Name: "酷酷酷酷酷",       ClientId: 1,       EqId: 1,     },     { headers: { "Content-Type": "application/form-data" } }   );   console.log("res:", res); };
后端

[HttpPost("DocList_Insert")]
public String DocList_Insert()
{
Debug.WriteLine("基础文档查找");
using (var ctx = new MyDbContext())
{
var knowType = new KnowType {Type="doc", Name = "2", ClientId= 1, EqId= 1 };
ctx.KnowType.Add(knowType);
ctx.SaveChanges();
return "200";//return 所有数据
}
}

修改后：

[HttpPost("DocList_Insert")]
public String DocList_Insert([FromForm] dataForm data)
{
Debug.WriteLine("基础文档查找");
using (var ctx = new MyDbContext())
{
Debug.WriteLine("插入数据:{0}",data);
var knowType = new KnowType {Type= data.Type, Name = data.Name, ClientId= data.ClientId, EqId= data.EqId };
ctx.KnowType.Add(knowType);
ctx.SaveChanges();
return "200";//return 所有数据
}
}
public class dataForm
{
public int ClientId { get; set; }
public int EqId { get; set; }
public string Name { get; set; }
public string Type { get; set; }
}

报错400原因是前端的请求头写错了
错误：{ headers: { "Content-Type": "application/form-data" } }

正确：{ headers: { "Content-Type": "multipart/form-data" } }
