摘要：
执行mongoexport命令时，mongoexport--csv fexternalSeqNum，paymentId--host127.0.1:27017-liveX-cconsume_ History-o0531bill。csv-q“｛”consumerStatus“：”SUCCESS“，”externalSeqNum“：/^201705/｝”报告了异常isnotvalidJSON：json
执行mongoexport命令的时候
mongoexport --csv -f externalSeqNum,paymentId --host 127.0.0.1:27017 -d liveX -c consume_history -o 0531bill.csv -q '{"consumeStatus":"SUCCESS","externalSeqNum":/^201705/}'
报了异常
is not valid JSON: json: cannot unmarshal string into Go value of type map[string]interface
去掉-q和过滤条件是没有问题的，那么问题就出在过滤条件上
后来发现是window和linux的区别，linux上执行是外面包单引号，window要外面包双引号
window写错："{'consumeStatus':'SUCCESS','externalSeqNum':/^201705/}" 就没有问题了
