linux下如何使用服务器curl模拟postman登录和下载？

工作需求，需要每日定时导出一个报表，但是由于要先登录，所以使用服务器curl模拟下载，具体如下：

#!/bin/bashcurdate=`date +%Y-%m-%d`#先获取tokena=`curl -H "Content-Type:application/json" -d '@1.json' http://x.x.x.x/ua/login`token=`echo $a|awk -F , '{print $2}' |awk -F : '{print $2}' |awk -F \" '{print $2}'`#导出区域GetArea() {curl  -o Area 'http://x.x.x.x/s1mca2iot-epidemicm11anage/e1pide1micsituationdailygg/exportAreaStatistic' -H 'Accept-Encoding: gzip, deflate' -H 'Accept-Language: zh,en;q=0.9,ja;q=0.8,zh-TW;q=0.7,fr;q=0.6,zh-CN;q=0.5' -H 'User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.75 Safari/537.36' -H 'Accept: application/json, text/plain, */*' -H 'Connection: keep-alive' -H "token: $token" --compressed}exportExcelWithArea() {curl  -o exportExcelWithArea "http://x.x.x.x/sss33mcccaiot-epid1emic2man1a1ge/epi2demic1situationdailygg/exportExcelWithArea?currentDay=$curdate" -H 'Accept-Encoding: gzip, deflate' -H 'Accept-Language: zh,en;q=0.9,ja;q=0.8,zh-TW;q=0.7,fr;q=0.6,zh-CN;q=0.5' -H 'User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.75 Safari/537.36' -H 'Accept: application/json, text/plain, */*' -H 'Connection: keep-alive' -H "token: $token" --compressed}GetAreasleep 3exportExcelWithAreasleep 30
