我正在使用这个 HackHands 示例来开始使用 Satellizer 并坚持运行 Express 服务器 - https://hackhands.com/building-instagram-clone-angularjs-satellizer-nodejs-mongodb/
这是我的 Server.js-

我总是在终端上收到此错误 - 语法错误:意外的标记； 在 Exports.runInThisContext (vm.js:73:16) 在 Module._compile (module.js:443:25) 在 Object.Module._extensions..js (module.js:478:10) 在 Module.load (module.js:355:32) 在 Function.Module._load (module.js:310:12) 在 Function.Module.runMain (module.js:501:10) 启动时(node.js:129:16) 在node.js:814:3
不确定我在这里缺少什么。有人可以帮忙吗？
我的package.json粘贴在下面-
{
“名称”:“instagram 服务器”， “版本”:“0.0.0”， “脚本”:{ “开始”:“Node 服务器.js” }, “依赖项”:{ "bcryptjs": "^2.0.2", "body-parser": "^1.8.1", “cors”:“^2.4.2”， " express ": "^4.9.0", "jwt-simple": "^0.2.0", "时刻": "^2.8.3", " Mongoose ": "^3.8.17", “请求”:“^2.44.0” }
}
最佳答案
我在按照本教程运行 Express 服务器时遇到了同样的问题。我所做的只是删除了 &
改变
if (!(req.headers &&req.headers.authorization))
至
if (!(req.headers && req.headers.authorization))
您还需要为所有包含 & 的后续函数更改它。
