我有一个Node.js后端,用于身份验证和ArangoDB Web界面的反向代理。我一辈子都无法弄清楚为什么我无法使用外部URL登录Web界面。
我搜索过高和低(谷歌,堆栈溢出,arangodb git发出线程,arangodb应用程序代码等),但无法弄清楚。我不了解下面使用的node-http-proxy模块。如果有人在节点内部以其他方式完成此操作。
我已经看到了使用nginx等的示例,但是我实际上是试图将所有内容都保留在节点后端之下,以便能够将代理访问权限保留在我的站点身份验证之后,因此我不会将Web Interface暴露给随机访问。
我希望已清除此障碍的人能够提供帮助。
问题: _open / auth请求永远不会响应。我仍然可以从服务器访问http://localhost:8529并登录。
所需结果: 从http://example.com:8080/_db/_system/_admin/aardvark/index.html#login访问Web界面并成功登录。

有趣的是:http://127.0.0.1:8080/_db/_system/_admin/aardvark/foxxes/fishbowl总是出现401错误(即使在本地地址和端口的服务器上,也认为这是aardvark.js的错误)
请参阅以下配置文件。

答案 0 :(得分:0)
我完全错失了一个事实,那就是您必须手动将帖子数据从表单转发到代理(以为这样做会自动完成)。另外,当您获取帖子正文并在值的末尾附加一个:“”时,node / arango做了一些奇怪的事情。因此,您必须手动将其删除。
