返回的是字符串，我们还需要将字符串转成对象 ``` let baseDate = JSON.parse(Base64.decode(result.data))//转码 字符串转json对象 _this.getHiChart(baseDate); ``` 1、在根目录下安装 ~~~ npm install --save js-base64 npm install --save js-md5 ~~~ 2、在项目文件中引入 ~~~ import md5 from 'js-md5'; let Base64 = require('js-base64').Base64; ~~~ 3、在项目文件中使用 ``` Base64.encode('dankogai'); // ZGFua29nYWk= Base64.encode('小飼弾'); // 5bCP6aO85by+ Base64.encodeURI('小飼弾'); // 5bCP6aO85by- Base64.decode('ZGFua29nYWk='); // dankogai Base64.decode('5bCP6aO85by+'); // 小飼弾 // note .decodeURI() is unnecessary since it accepts both flavors Base64.decode('5bCP6aO85by-'); // 小飼弾 ``` md5 ``` md5(''); // d41d8cd98f00b204e9800998ecf8427e md5('The quick brown fox jumps over the lazy dog'); // 9e107d9d372bb6826bd81d3542a419d6 md5('The quick brown fox jumps over the lazy dog.'); // e4d909c290d0fb1ca068ffaddf22cbd0 // It also supports UTF-8 encoding md5('中文'); // a7bac2239fcdcb3a067903d8077c4a07 // It also supports byte `Array`, `Uint8Array`, `ArrayBuffer` md5([]); // d41d8cd98f00b204e9800998ecf8427e md5(new Uint8Array([])); // d41d8cd98f00b204e9800998ecf8427e // Different output md5(''); // d41d8cd98f00b204e9800998ecf8427e md5.hex(''); // d41d8cd98f00b204e9800998ecf8427e md5.array(''); // [212, 29, 140, 217, 143, 0, 178, 4, 233, 128, 9, 152, 236, 248, 66, 126] md5.digest(''); // [212, 29, 140, 217, 143, 0, 178, 4, 233, 128, 9, 152, 236, 248, 66, 126] md5.arrayBuffer(''); // ArrayBuffer md5.buffer(''); //instead. ```
