wx.uploadFile上传图片后，我们的后台返回的是个数组，但是微信把它变成了下面这个样子，请问这个怎么弄啊？"[ { "id" : 20332, "sign" : "image", "imagePath" : "http://139.224.206.114:8080/uploadFile/2017-04-21/image/7c1a2368-0f48-403b-8bc5-c00b6b266c13-7009.jpeg", "img-min" : "2017-04-21/image/7c1a2368-0f48-403b-8bc5-c00b6b266c13-7009-min.jpeg", "img-mid" : "2017-04-21/image/7c1a2368-0f48-403b-8bc5-c00b6b266c13-7009-mid.jpeg", "img" : "/uploadFile/2017-04-21/image/7c1a2368-0f48-403b-8bc5-c00b6b266c13-7009.jpeg", "fileName" : "tmp_984848017o6zAJsyHUyB0xEvz5oeVZNyoWXzgfb65df3db6bcc63c2d802c600adc02c3.jpeg", "code" : "10000", "msg" : 20332, "size" : 149780 } ]"
