axios传数据单个为null

上代码

要求传到后台是JSON,数组一直穿不过去，我就直接全转成String,没想到只有数组用string,搞的头疼
     
	let ks = JSON.stringify(this.dataChild)
				this.Dfater.DSTATERUN = 1;
				let cc = {...this.Dfater,subListStr:ks}
				console.log(ct)
				return false;
				this.$axios.post('xxxxxxxxxxxx',qs.stringify(cc)).then(res=>{
					console.log(res,'添加结果')
				})
