目录结构

设置解决方案为多个项目启动

一、使用jQuery Ajax访问

（一）、表单传参( [FromForm])

数据类型：Object

ContenyType类型：application/x-www-form-urlencoded

?
1
var model = { name: "刘大大", age: 23, sex: true };

前台请求

?

var model = { name: "刘大大", age: 23, sex: true };      
$.ajax({
    url: "http://localhost:9001/API/Default/FormCall",
    type: "POST",
    async: true,
    dataType: "json",
    data: model,
    contentType: "application/x-www-form-urlencoded",
    success: function (data) {
        console.log("data:");
        console.log(data);
    }
});

(二）、JSON字符串[FromBdy]

数据类型：Json

ContenyType类型：application/json

?
1
       var json = '{"name":"刘大大","age":23,"sex":true}';

也可以使用JSON.stringify(Object)将Object转换为JSON字符串

前端请求

var model = { name: "刘大大", age: 23, sex: true };      
$.ajax({
    url: "http://localhost:9001/API/Default/BodyCall",
    type: "POST",
    async: true,
    dataType: "json",
    data: JSON.stringify(model),
    contentType: "application/json",
    success: function (data) {
        console.log("data:");
        console.log(data);
    }
});

（三）、文件上传

建立FormData对象

数据类型：FromData

ContenyType类型false, //必须false才会避开jQuery对 formdata 的默认处理 processData类型: false, //必须false才会自动加上正确的Content-Type

html

?
1
<input type="file" multiple id="file" />

JS获取文件对象

var file = document.getElementById("file");
 var files = file.files;
 var formData = new FormData();
 for (var i = 0; i < files.length; i++) {
     formData.append(files[i].name, files[i]);
 }　　　　
formData.append("name", "刘大大");//可追加参数

           dataType: "json",
           data: formData,
           contentType: false,
           processData: false,
           success: function (data) {
               console.log(data);
           }
