小程序json字符串转为对象

时间：2020-12-26 03:51:34

小程序里json字符串转为对象使用JSON.parse()方法转变无效, 看报错提示有单引号“ ' ” 因为单引号而无效, 将单引号全改双引号即可.

报错如下:

VM11050:1 thirdScriptError
Unexpected token ' in JSON at position 1;at pages/address/address onLoad function;at api getStorage success callback function
SyntaxError: Unexpected token ' in JSON at position 1...

截图如下:

错误注释,已改正如下:

    wx.getLocation({

            success: function (res) {

                var lng = res.longitude;

                var lat = res.latitude;

                var requestUrl = "https://apis.map.qq.com/ws/geocoder/v1/?location=" + lat + "," + lng + "&key=D6CBZ-D7PHQ-G7L54-GZJKF-B3PDK-MZBR4"

                wx.request({

                    url: requestUrl,

                    success: function (res) {

                        var province = res.data.result.address_component.province;

                        var city = res.data.result.address_component.city;

                        var district = res.data.result.address_component.district;

                        var address = res.data.result.address;
　　　　　　　　　　　　　　　　//不识别单引号,下面一行改正// var location = "{'province': '" + province + "','city':'" + city + "','district':'" + district + "','address':'" + address + "','lng':" + lng + ",'lat':" + lat + "}"
var location = "{\"province\": \"" + province + "\",\"city\":\"" + city + "\",\"district\":\"" + district + "\",\"address\":\"" + address + "\",\"lng\":\"" + lng + "\",\"lat\":\"" + lat + "\"}";

　　　　　　　　　　　　　　　　　　　　　

                        wx.setStorage({

                            key: 'location_key',

                            data: location

                        })

                    }

                })

            },

        })

    },
