        const formData = new FormData();
        formData.append("file",$("#photo")[0].files[0]);
        //formData.append("user",'{"name":"11","age":12}');
        formData.append('user', new Blob([JSON.stringify({
            "name": "11",
            "age": 12
        })], {
            type: "application/json"
        }));
        const settings = {
            "url": "http://localhost:8080/upload",
            "method": "POST",
            "timeout": 0,
            "processData": false,
            "mimeType": "multipart/form-data",
            "contentType": false,
            "data": formData
        };

        $.ajax(settings).done(function (response) {
            console.log(response);
        });

關(guān)鍵在于FormData.append方法的第二個(gè)參數(shù)是可以指定參數(shù)類型的
