前端生成32位uuid 

            uuid() {
                const len = 32;      //32长度
                let radix = 16;    //16进制
                const chars = '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'.split('');
                let uuid = [], i;
                radix = radix || chars.length;
                if (len) {
                    for (i = 0; i < len; i++) {
                        uuid[i] = chars[0 | Math.random() * radix];
                    }
                } else {
                    let r;
                    uuid[8] = uuid[13] = uuid[18] = uuid[23] = '-';
                    uuid[14] = '4';
                    for (i = 0; i < 36; i++) {
                        if (!uuid[i]) {
                            r = 0 | Math.random() * 16;
                            uuid[i] = chars[(i == 19) ? (r & 0x3) | 0x8 : r];
                        }
                    }
                }
                return uuid.join('');
            },
