前端这样传参后端怎样接收

```javascript
{tdJoinAndBrands: Array(1), tdJoinAndCellBrands: Array(1), joAddress: "浙江省杭州市西湖区浙大路1号", longitude: "", latitude: "", …}companyName: "dg"
detailedAddress: "是多大"
joAddress: "浙江区路1号"
joBusiness: []
joMaintain: []
joName: "xiaogui"
joPhone: "17695178029"
joStore: []
latitude: ""
longitude: ""
mainBusiness: (3) ["2", "5", "8"]
nameOfShop: "gsd"
synopsis: "dsfs"
tdJoinAndBrands: Array(1)0: {brandName: "吉利", brandId: 15}
length: 1
nv_length: (...)
__proto__: Array(0)
tdJoinAndCellBrands: Array(1)0: {cellBrandName: "宁德时代", cellBrandNumber: 47001}
length: 1
nv_length: (...)
__proto__: Array(0)
__proto__: Object

```

后端是这么接收的,接收不到, 注释掉的JSON转换使用String接收, 然后转JSON, 但是String接收不到参数, 是null

后端可以解析json字符串的，可以转成相应对象的。

post请求放data里传给后端即可
