curl 301 processing

When I was processing an interface call, I found that postman could respond to data normally, but the normal data response could not be obtained when the program was running.

Check the log and find that curl in the code will return 301, which will cause the interface to fail to obtain the response data correctly.

curl -i http://www.example.com/fetchAvailability\?startDate\=2021-02-08\&endDate\=2021-02-08\&startTime\=00%3A00%3A00\&endTime\=23%3A59%3A59
