Question

我在psql上使用psycopg2和sslmode=require和psql: SSL error: certificate verify failed连接到Heroku Postgres时遇到了令人沮丧的问题。

在debian（python 2.7.13）上连接下一个示例时，我遇到了

的相同问题

psql "host=<MyHost> sslmode=require" --port=5432 --username=<MyUser> --password

psql：

import psycopg2
db_url =  "postgres://User:Pwd@Host:5432/DB?sslmode=require"
psycopg2.connect(db_url)

Psycopg2：

postgresql.conf

我尝试按照此处所述更改pg_hba.conf和psycopg2=-2.6.2 OpenSSL=1.1.0j 20 Nov 2018 postgres=9.6： PSQL: SSL error: unknown protocol

没有运气。

Answer 1

好的。我发现在系统中，var iQuantity = parseFloat(oArticle._Quantity); var regexp = new RegExp('^([0-9]{1,4})(\.[0-9]{1,2})?$').test(iQuantity); console.log(iQuantity); console.log(regexp); if (regexp === false) { return this.setItemToError(oInput, oArticle, this.getResourceBundle().getText("regExp")); }目录中有一个root.crt文件。 ~/postgresql文件引起了整个问题（它没有通过Heroku认证），当我删除它时，连接就起作用了。
