1、在Startup.cs ConfigureService 中加入(需要通过Nuget 增加Microsoft.AspNetCore.Mvc.NewtonsoftJson)
services.AddControllersWithViews().AddNewtonsoftJson();
2、 控制器
public IActionResult getRelevantSearch() { string keyWord = Request.Query["keyword"]; if (reg.IsMatch(keyWord)) { var getData = bll.getRelevancySearch(keyWord); if (getData != null) { return Json(new { code = 200, msg = "获取成功", data = getData }); } } return Json(new { code =400, msg = "获取失败", data="" }); }
3、 效果:
