1.前端提交JSON 字符串
{"id":13,"title":"这里是标题33","day":"2018-8-16","status":0,"arr":[{"type":"r","quest":"333","q1":"3","q2":"3","q3":"3"},{"type":"c","quest":"444","q1":"4","q2":"4","q3":"4"},{"type":"t","quest":"5"}]} ???????????$.ajax({ ???????????????url: "/survey/post", ???????????????method:"post", ???????????????data: json, ???????????????contentType: "application/json", ???????????????success: function (data) { ???????????????????console.log(data.status); ???????????????} ???????????}) ?后端MVC controller ( version<=5) , 如果是WebAPI, 则要加上[FromBody]修饰参数
???public class SurveyDTO ???{ ???????public string id { get; set; } ???????public string title { get; set; } ???????public DateTime day { get; set; } ???????public string status { get; set; } ???????public SurveyItem[] arr { get; set; } ???} ???public class SurveyItem { ???????public string type { get; set; } ???????public string quest { get; set; } ???????public string q1 { get; set; } ???????public string q2 { get; set; } ???????public string q3 { get; set; } ???} ???????[HttpPost] ???????public ActionResult Post(SurveyDTO data) ???????{}JSON带有数组的话, 通常不能直接用EntityFramework的实体.要重新定义.
2. 前端使用表单提交
$.post(‘/survey/postForm‘, $(‘#form‘).serialize(), function (json) { ???????????if (json.isSuccess) { ??????????????????????????} ???????});
$.ajax({
???????????????url: "/survey/postForm",
???????????????method: "post",
???????????????data: "id=" + key + "&title=" + title + "&day=" + date + "&status=" + sta + "&arr=" + JSON.stringify(this.storageArr),
???????????????success: function (data) {
???????????????????console.log(data.status);
???????????????}
???????????})
后端使用Formcollection 接受参数
???????[HttpPost] ???????public ActionResult Post(FormCollection form) ???????{ ???????????var json = new { status = 0 }; ???????????return Json(json); ???????}
MVC的前端和后端的Model Binding
