Question

我正在尝试配置我的节点应用程序，并且当前显示以下错误：

错误：大多数中间件（如bodyParser）不再与Express捆绑在一起，必须单独安装。请参阅https://github.com/senchalabs/connect#middleware。

我当时在网站上，并且不确定我应该寻找什么，因为我对Node.js很陌生。感谢您的帮助！

这是完整的消息。

Answer 1

您已经以正确的方式在应用程序顶部定义了中间件：app.use(bodyParser.json());

您还需要在代码中再定义一次，这是不正确的方式，因为最新版本的express没有随附用于正文解析器的内置中间件。

删除此行：app.use(express.bodyParser());

与节点建立连接时出错“大多数中间件（如bodyParser），必须由nodejs单独安装”
