ERR_TOO_MANY_REDIRECTS:我的代码是否被锁定在一个循环中? [英] ERR_TOO_MANY_REDIRECTS: Is my code locked in a loop?
问题描述
我正在尝试完成 Tableau .js API 教程，但当我尝试将在线示例与我发布到我们服务器上的图表一起使用时，我立即陷入了 ERR_TOO_MANY_REDIRECTS 错误.
I'm trying to work through the Tableau .js API tutorial, and immediately I got stuck with a ERR_TOO_MANY_REDIRECTS error when I tried to use the online example with a chart I posted to our server.
我对这项工作很陌生，所以我想我会提供相关的片段，看看你是否能发现任何可能在循环中产生重定向的东西.
I am pretty new to this work, so I thought I'd offer the relevant snippet and see if you can spot anything that's likely to generate re-directs in a loop.
一些注意事项:"只是一个虚拟替代品.这不是问题.
Some notes: "" is just a dummy substituion. It is not the problem.
这是代码.感谢您的建议！
Here is the code. Thanks for any advice!

推荐答案
与代码无关.我发现这是一个凭据问题.我不太了解安全性和登录解析，但也许这会对某人有所帮助:我通过提前登录 Tableau 解决了这个问题，以便我的凭据已经为该会话建立.然后当我重新加载上面的代码时，它起作用了.所以我推断，如果此代码对其他用户运行良好，我必须提前解决凭证传递问题.无论如何，这就是我接下来要尝试的解决方案.HTH
It's nothing to do with the code. I found that it's a credentialing issue. I don't know much about security and log-in resolution, but perhaps this will help someone: I resolved the issue by FIRST logging into Tableau in advance, so that my credentials were already established for that session. Then when I reloaded the above code, it worked. So I infer that I have to work out the credential pass-through issues in advance if this code is going to work well for other users. Anyway, that's the solution path I'm trying next. HTH
