1.通過查看日志，可以看出問題的原因。

2.斷點調(diào)試。

3.本地測試，確保無誤后，線上測試。

4.輸出測試。

通過get的方式，測試接口。

// [HttpPost]
public ActionResult SearchGroup(string appType, string keyWord, string userName)
{
    GroupListModel model = new GroupListModel(); // 新建model對象
    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);
}

通過post的方式，測試接口。

[HttpPost]
public ActionResult SearchGroup(string appType, string keyWord, string userName)
{
    GroupListModel model = new GroupListModel(); // 新建model對象
    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 });
}

有時候編輯器不報錯，不一定就是完全正確的。

下面是接口的終端代碼

[HttpPost]
public ActionResult SearchGroup(string appType, string keyWord, string userName)
{
    GroupListModel model = new GroupListModel(); // 新建model對象
    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 });
}

目標(biāo)是獲取群組數(shù)據(jù)，
首先創(chuàng)建一個GroupListModel。它的Group屬性，對應(yīng)GroupModel。GroupModel中有相應(yīng)的所需的屬性值。

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; }
    }
}

然后根據(jù)_groupService的SearchGroup方法查詢數(shù)據(jù)，這里主要是一些與數(shù)據(jù)庫交互的方法。各種增刪改查都在這里進(jìn)行。

            return query.ToList();
        }
        #endregion

}

獲取groups數(shù)據(jù)之后，將其賦值到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
        });
}

最后通過Json輸出，

return Json(new { result = true, info = model });

編譯好之后，將下面的dll上傳發(fā)布，測試。
