在 python3 中出现 psycopg2 错误
get psycopg2 errors in python3
我有 psycopg2 版本 2.6.1
我想获取一些错误,但它没有按预期工作:
try:
pgconn = psycopg2.connect(database="foobar", host="dbtest.example.de", user="postgresss")
except psycopg2.OperationalError:
print(psycopg2.OperationalError.pgerror)
.....:
<member 'pgerror' of 'psycopg2.Error' objects>
或:
try:
pgconn = psycopg2.connect(database="foobar", host="dbtest.example.de", user="postgresss")
except psycopg2.OperationalError:
print(psycopg2.OperationalError.diag)
.....:
<attribute 'diag' of 'psycopg2.Error' objects>
我怎样才能看到像 "no pg_hba.conf entry for host xyz"
这样的正确消息
您需要引用异常实例:
try:
pgconn = psycopg2.connect(database="foobar", host="dbtest.example.de", user="postgresss")
except psycopg2.OperationalError as e:
print(e)
