用exress写了个报错用户提交信息的接口，总是报错， {“type”:“error”,“user”:{“realName”:“肖占慧”,“timePassAfterAnsterAQ”:false,“vipCode”:0,“positionId”:“599ce7f8d7d917496a8d4132”,“guid”:“8aac08e6-a1bc-4ffa-8178-28bee2666c31”},“resp”:{“data”:null,“status”:0,“config”:{“method”:“POST”,“transformRequest”:[null],“transformResponse”:[null],“url”:"/cand/api/saveAnswer",“data”:{“paperId”:“599ce8133611007cdb0bbe5e”,“quesNo”:1000,“ans”:“3”},“headers”:{“Accept”:“application/json, text/plain, /”,“Content-Type”:“application/json;charset=utf-8”}},“statusText”:""}}
