SET SSL_VERIFY as NO to download CSV file from KDB

I have kdb 64 bit installed on windows and wanted to run below kdb command to download a csv file and load it as table into data variable.

q)("**III";1#",") 0: "\n" vs .Q.hg"https://data.cityofnewyork.us/api/views/f9bf-2cp4/rows.csv"

But this leads to a 'conn ( connection error ) .

C80A0000:error:80000003:system library:file_ctrl:No such process:crypto\bio\bss_file.c:297:calling fopen(C:\Windows\System32\OpenSSL\SSL/server-crt.pem, rb)

On unix we can export variable as

$ export SSL_VERIFY=NO

But how do we do equivalent of this in windows ? I tried to modify environment variable in windows. But this does not seem to work.

Solution

  • try with http not https
