问题描述

我正在尝试连接到Heroku上我的应用程序的PostgreSQL数据库:

I'm trying to connect to the PostgreSQL database of my app on Heroku:

$host = "ec2-54-235-242-31.compute-1.amazonaws.com";
$username = "user";
$password = "pass";
$database = "dbname";
$port = "5432";

$dbconn = pg_connect("host=".$host." port=".$port
          ." dbname=".$database." user=".$username." password=".$password)
or die('Could not connect: ' . pg_last_error());

但我遇到此错误:

警告:pg_connect()[function.pg-connect]:无法连接到PostgreSQL服务器:严重:主机 69.196.177.196,用户 user,数据库没有pg_hba.conf条目 dbname,第53行的D:\wamp\www\heroku_app\test.php中的SSL关闭

Warning: pg_connect() [function.pg-connect]: Unable to connect to PostgreSQL server: FATAL: no pg_hba.conf entry for host "69.196.177.196", user "user", database "dbname", SSL off in D:\wamp\www\heroku_app\test.php on line 53

这是问题吗?我该如何解决?

What is the problem here? How can I fix it?

注意:仅当我在本地计算机上运行时(通过WAMP服务器),这种情况才会发生。如果我将其部署到Heroku,那么它将运行正常

Note: this only happens when I run on my local machine (via WAMP server). If I deploy it to Heroku then it runs fine

推荐答案

此处的关键错误是 SSL关闭。 Heroku Postgres需要SSL进行外部连接。确保您的PHP使用SSL编译,并在您的连接中指定 sslmode = require

The key error here is SSL off. Heroku Postgres requires SSL for external connections. Make sure your PHP was compiled with SSL and specify it in your connection sslmode=require.
