前台可以获取到数据，但通过ajax传到后台就没有了
$(function () {
var initUrl = '/o2o/shop/info_init';
var registerUrl = '/o2o/shop/register';
getInitInfo();
function getInitInfo() {
$.getJSON(initUrl, function (data) {
if (data.success) {
var tempHtml = '';
var tempAreaHtml = '';
data.shopCategoryList.map(function (item) {
tempHtml += '<option data-id="' + item.shopCategoryId + '">'
+ item.shopCategoryName + '</option>';
})
data.areaList.map(function (item) {
tempAreaHtml += '<option data-id="' + item.areaId + '">'
+ item.areaName + '</option>';
})
$('#shop-category').html(tempHtml);
$('#area').html(tempAreaHtml);
}
});
}
$('#submit').click(function () {
var shop = {};
shop.shopName = $('#shop-name').val();
shop.shopAddr = $('#shop-addr').val();
shop.phone = $('#shop-phone').val();
shop.shopDesc = $('#shop-desc').val();
shop.shopCategory = {
shopCategoryId: $('#shop-category').find('option').not(function () {
return !this.selected;
}).data('id')
};
shop.area = {
areaId: $('#area').find('option').not(function () {
return !this.selected;
}).data('id')
};
var shopImg = $('#shop-img')[0].files[0];
var formData = new FormData();
// 添加图片流进表单对象里
formData.append('shopImg', shopImg);
// 将shop json对象转成字符流保存至表单对象key为shopStr的的键值对里
formData.append('shopStr', JSON.stringify(shop));
// 获取表单里输入的验证码
var verifyCodeActual = $('#verify-code').val();
if (!verifyCodeActual) {
$.toast('请输入验证码');
return;
}
formData.append('verifyCodeActual', verifyCodeActual);
// 将数据提交至后台处理相关操作
$.ajax({
url : registerUrl,
type : 'POST',
data : formData,
contentType : false,
processData : false,
cache : false,
success : function(data) {
if (data.success) {
$.toast('提交成功！');
} else {
$.toast('提交失败！' + data.errMsg);
}
// 点击验证码图片的时候，注册码会改变
$('#kaptcha_img').click();
}
});
});

同学你好，建议同学查看debug时，formData.append()这句代码中，verifyCodeActual是否有值，如：
如果这里有值，建议同学先将验证码判断注释掉，继续向后执行，查看shopStr的值是否传入到后台。
祝：学习愉快~
request里不知道为什么好像没有保存key为shopStr的值，而且ajax发送的是post请求，为什么url里会有“？”，接收不到数据是不是和这个有关系？
