问题描述



我使用pg 7.4.2 npm软件包。

我的数据库升级到10.2后似乎无法连接。

要清楚的是,我已经连续6个月没有问题地使用相同的连接字符串,该连接字符串具有?ssl = true附加到它。


$ b $

  AssertionError [ERR_ASSERTION]:false == true 
位于Object.exports.connect(_tls_wrap.js:1099:3)
位于Socket。< anonymous> (/home/e/express/testpg/node_modules/pg/lib/connection.js:94:23)
在Object.onceWrapper(events.js:219:13)
在Socket.emit(

at addChunk(_stream_readable.js:269:12)
at readableAddChunk(_stream_readable.js :256:11)
at Socket.Readable.push(_stream_readable.js:213:10)
at TCP.onread(net.js:598:20)

我尝试在连接字符串的末尾添加/删除?ssl = true,并在构造函数中添加/删除ssl:true。我也尝试过和没有承诺。同样的错误,无论本地和部署到heroku上。



进口:

  import {Pool,Client} from'pg'

方法1:

  let pool = new Pool({
connectionString:csnew,
ssl:true
})

pool.connect()。then(client => {
console.log('connected')
})
.catch(e => {
console.log(e)
})

方法2:

  let pgclient = new Client({
connectionString:csnew,
ssl:true
))
pgclient.connect()。then(()=> {
console.log('connected')
})。catch(e => {
console.log (e)
})


解决方案

v7.4.2打破了对SSL的支持。 这是未解决的问题



您必须严格使用v7.4.1才能解决问题。



更新



7.4.3版解决了问题。


It seems after my database was upgraded to 10.2 I'm unable to connect.

I'm using the pg 7.4.2 npm package.

To be clear, I have been connecting without issue for 6 months using the same connection string which had ?ssl=true appended to it.

I get this error connecting via Pool or Client.

AssertionError [ERR_ASSERTION]: false == true
    at Object.exports.connect (_tls_wrap.js:1099:3)
    at Socket.<anonymous> (/home/e/express/testpg/node_modules/pg/lib/connection.js:94:23)
    at Object.onceWrapper (events.js:219:13)
    at Socket.emit (events.js:127:13)
    at Socket.emit (domain.js:421:20)
    at addChunk (_stream_readable.js:269:12)
    at readableAddChunk (_stream_readable.js:256:11)
    at Socket.Readable.push (_stream_readable.js:213:10)
    at TCP.onread (net.js:598:20)

I'm now hardcoding the full postgres connection string so there is no issue with env variables.

I've tried adding/removing ?ssl=true to the end of the connection string and adding/removing ssl:true from the constructor. I've also tried with and without promises. Same error no matter what on both local and deployed to heroku.

imports:

import { Pool, Client } from 'pg'

method 1:

let pool = new Pool({
  connectionString: csnew,
  ssl: true
})

pool.connect().then( client => {
  console.log('connected')
})
.catch(e=> {
  console.log(e)
})

method 2:

let pgclient = new Client({
  connectionString: csnew,
  ssl: true
})
pgclient.connect().then( () => {
  console.log('connected')
}).catch(e=> {
  console.log(e)
})

解决方案

That's because v7.4.2 broke its SSL support. Here's the open issue.

You need to use strictly v7.4.1 till the issue is resolved.

UPDATE

Version 7.4.3 fixed the issue.
