去除js中的json存在的转义字符\

js中打印出的示例：执行console.log(JSON.stringify(d).toString()),得到以下信息：{"businessNumber":"HT-2019001","filesInfo":"[{\"fileName\":\"test.jpg\",\"groupName\":\"group1\",\"fdfsId\":\"M00/00/00/rBMBBERDSsG...

js中打印出的示例：

执行

console.log(JSON.stringify(d).toString()),得到以下信息：

{"businessNumber":"HT-2019001","filesInfo":"[{\"fileName\":\"test.jpg\",\"groupName\":\"group1\",\"fdfsId\":\"M00/00/00/rBMBBERDSsGAWFZFAAEe88kVsg8661.jpg\"},{\"fileName\":\"test02.sql\",\"groupName\":\"group1\",\"fdfsId\":\"M00/00/00/rBMAA12ENqmAERVQAAAfFFZ78oA526.sql\"}]"}

console.log(JSON.stringify(d).toString().replace(new RegExp("\\\\\"","gm"),"\"")),得到以下信息：

{"businessNumber":"HT-2019001","filesInfo":"[{"fileName":"test.jpg","groupName":"group1","fdfsId":"M00/00/00/rBMBBERDSsGAWFZFAAEe88kVsg8661.jpg"},{"fileName":"test02.sql","groupName":"group1","fdfsId":"M00/00/00/rBMAA12ENqmAERVQAAAfFFZ78oA526.sql"}]"}

结论：js中的json串出现单个反斜杠 \ 时，替换需要用 \\\\ 。
