1.通过查看日志，可以看出问题的原因。
2.断点调试。
3.本地测试，确保无误后，线上测试。
4.输出测试。
通过get的方式，测试接口。
// [HttpPost]
public ActionResult SearchGroup(string appType, string keyWord, string userName)
{
GroupListModel model = new GroupListModel(); // 新建model对象
var groups = _groupService.SearchGroup(appType, keyWord);
foreach (var item in groups)
{
model.Group.Add(new GroupModel()
{
GroupId = item.Id,
Title = item.Title,
Avatar = item.Avatar,
OwnerId = item.OwnerId,
IsDismiss = item.IsDismiss
});
}
// return Json(new { result = true, info = model });
return Json(new { result = true, info = model }, JsonRequestBehavior.AllowGet);
}
通过post的方式，测试接口。
[HttpPost]
public ActionResult SearchGroup(string appType, string keyWord, string userName)
{
GroupListModel model = new GroupListModel(); // 新建model对象
var groups = _groupService.SearchGroup(appType, keyWord);
foreach (var item in groups)
{
model.Group.Add(new GroupModel()
{
GroupId = item.Id,
Title = item.Title,
Avatar = item.Avatar,
OwnerId = item.OwnerId,
IsDismiss = item.IsDismiss
});
}
return Json(new { result = true, info = model });
}
有时候编辑器不报错，不一定就是完全正确的。
下面是接口的终端代码
[HttpPost]
public ActionResult SearchGroup(string appType, string keyWord, string userName)
{
GroupListModel model = new GroupListModel(); // 新建model对象
var groups = _groupService.SearchGroup(appType, keyWord);
foreach (var item in groups)
{
model.Group.Add(new GroupModel()
{
GroupId = item.Id,
Title = item.Title,
Avatar = item.Avatar,
OwnerId = item.OwnerId,
IsDismiss = item.IsDismiss
});
}
return Json(new { result = true, info = model });
}
目标是获取群组数据，
首先创建一个GroupListModel。它的Group属性，对应GroupModel。GroupModel中有相应的所需的属性值。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace Ddd.Web.Models.Customer
{
public partial class GroupListModel
{
public GroupListModel()
{
this.Group = new List<GroupModel>();
}
public List<GroupModel> Group { get; set; }
}
public partial class GroupModel
{
public int GroupId { get; set; }
public string Title { get; set; }
public string Avatar { get; set; }
public bool IsFriend { get; set; }
public int OwnerId { get; set; }
public bool IsDismiss { get; set; }
}
}
然后根据_groupService的SearchGroup方法查询数据，这里主要是一些与数据库交互的方法。各种增删改查都在这里进行。

using Ddd.Core.Data;

}
}
获取groups数据之后，将其赋值到model中去，
foreach (var item in groups)
{
model.Group.Add(new GroupModel()
{
GroupId = item.Id,
Title = item.Title,
Avatar = item.Avatar,
OwnerId = item.OwnerId,
IsDismiss = item.IsDismiss
});
}
最后通过Json输出，
return Json(new { result = true, info = model });
编译好之后，将下面的dll上传发布，测试。
小结;实践出真知，你们看了也没用，自己多练练吧。
