URI::InvalidComponentError: bad component(expected host component): localhost:3000

Question

我不確定出了什么問題，但是在控制台中運行NewsletterMailer.weekly("username-here@gmail.com").deliver我收到錯誤URI::InvalidComponentError: bad component(expected host component): localhost:3000

我仔細檢查了我的設置，一切似乎都很好。 這是錯誤的完整 output：

Answer 1

從您指定為默認主機的URL中刪除端口號。 :host密鑰的值應該只是主機，而不是主機和端口號。

Answer 2

如果Zajn的答案不起作用，那么搜索localhost:3000 。 你可能把它放在其他地方。 當你發現它刪除該行，它應該工作。

Answer 3

您可能在配置中的某處有一行config.roadie.url_options = { host: "localhost:3000" } ，也許是development.rb。 road.url_options要求將端口指定為單獨的密鑰。

請嘗試使用config.roadie.url_options = { host: "localhost", port: 3000 } 。

我遇到了同樣的問題，嘗試用這個命令啟動服務器

bundle exec rails server -b 127.0.0.1
