将Google Cloud Function连接到Oracle数据库

Question

Does anyone know, how to connect google cloud function(Python) to an Oracle database ? I tried importing cx_Oracle library in cloud function. But it shows an error

Function load error: DPI-1047: Oracle Client library cannot be loaded: libclntsh.so: cannot open shared object file

Following is main.py code:

import cx_Oracle

def import_data(request):

    request_json = request.get_json()
    if request_json and 'message' in request_json:
        con = cx_Oracle.connect("username", "password", "host:port/SID")
        print(con.version)
        con.close

Following is requirement.txt

# Function dependencies, for example:
# package>=version
cx_Oracle==6.0b1

It seems Google Cloud Functions does not support shared libraries (in other words, it only supports "pure python" libraries) and that cx_oracle depends on this. Sadly I haven't been able to find a pure-python Oracle library, so for now this is not supported.

Your best bet is to use App Engine Flexible as it the closest equivalent service that allows non-pure python libraries . cl_oracle should work with it.
