is not valid JSON: json: cannot unmarshal string into Go value of type map[string]interface | mongodb在windows和Linux導出出錯

執行mongoexport命令的時候

mongoexport --csv -f externalSeqNum,paymentId --host 127.0.0.1:27017 -d liveX -c consume_history -o 0531bill.csv -q '{"consumeStatus":"SUCCESS","externalSeqNum":/^201705/}'

報了異常

is not valid JSON: json: cannot unmarshal string into Go value of type map[string]interface

去掉-q和過濾條件是沒有問題的，那么問題就出在過濾條件上

后來發現是window和linux的區別，linux上執行是外面包單引號，window要外面包雙引號

window寫錯："{'consumeStatus':'SUCCESS','externalSeqNum':/^201705/}" 就沒有問題了
