当我的密码包含 at 符号 (@) 时,如何指定 Diesel DATABASE_URL?

How do I specify a Diesel DATABASE_URL when my password contains an at-sign (@)?

我是按照他们的 official documentation 开始使用 Diesel 的。我还安装了 PostgreSQL。我的数据库用户名是 postgres,密码是 1schoollife@.

我从

开始
$ echo DATABASE_URL=postgres://postgres:1schoollife@@localhost/diesel_demo > .env
$ diesel setup

结果:

Creating migrations directory at: /home/naufil/Desktop/rust/3june/testing/migrations
Creating database: diesel_demo
database "diesel_demo" already exists

我创建了一个迁移:

$ diesel migration generate create_posts
Creating migrations/2019-06-03-182531_create_posts/up.sql
Creating migrations/2019-06-03-182531_create_posts/down.sql

迁移数据库时出现以下错误:

$ diesel migration run
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: ConnectionError(BadConnection("could not translate host name \"@localhost\" to address: Name or service not known\n"))', src/libcore/result.rs:997:5
note: Run with `RUST_BACKTRACE=1` environment variable to display a backtrace.

您提供的 DATABASE_URL 不是您尝试使用的 URL。 @ 是一个特殊字符,用于将凭据与主机名分开。由于您的凭据包含 @,因此需要对其进行 URL 转义:

postgres://postgres:1schoollife%40@localhost/diesel_demo

Yes, percent encoding is 100% the correct thing for us to be doing.

这是在 PR 1058
