Firebase云端函数：“错误：无法处理请求” [英] Cloud Functions for Firebase: 'Error: could not handle the request'

问题描述

我感觉要把头发拉出来，这是要么超级简单，我脑冻结或不是那么简单。

我想要什么

我试图用firebase解开一个缩短的URL，当用户转到：
myapp.firebaseappurl.com/url/SHORTENEDLINK >
所以不会让我添加一个简短的URL

我想输出为：

  {
url：https://stackoverflow.com/questions/45420989/sphinx-search-how-to-use-an -empty-before-match-and-after-match
} 
  

尝试

firebase.json file：

<$ p $
hosting：{
public：public，
rewrites：[{
source：/ url /：item，
destination：/ url /：item
}]
}
}
pre>

index.js file：

  const函数= require（'firebase-functions'）; 
 $ b $ exports.url = functions.https.onRequest（（requested，response）=> {
 
 var uri = requested.url; 
 request（{
 uri：uri，
 followRedirect：true 
}，
 function（err，httpResponse）{
 if（err）{
 return console.error（err ）; 
} 
 response.send（httpResponse.headers.location || uri）; 
} 
）; 
 
}）; 
  

结果

code> myapp.firebaseappurl.com/url/SHORTENEDLINK 我得到以下内容：

 错误：无法处理请求
  

解决方案

{source：'/ url / **'} 语法

你可以使用类似的东西; p>

  {
hosting：{
public：public，
rewrites ：[{
source：/ url / **，
function：/ url
}] 
} 
} 
  

然后您可以从请求中解析网址。

  exports.url = functions.https.onRequest（（req，res）=> {
 //从req解析url并重定向到正确的链接
}）; 
  

I feel like pulling my hair out; this is either super simple and i'm having brain freeze or it is not that simple.

What I want

I am trying to unshorten a shortened URL using firebase, when a user goes to:
myapp.firebaseappurl.com/url/SHORTENEDLINK
SO wont let me add a shortened URL

I would like the output to be:

{
  "url": "https://stackoverflow.com/questions/45420989/sphinx-search-how-to-use-an-empty-before-match-and-after-match"
}

What I have tried

firebase.json file:

{
  "hosting": {
    "public": "public",
    "rewrites": [ {
    "source": "/url/:item",
      "destination": "/url/:item"
    } ]
  }
}

index.js file:

const functions = require('firebase-functions');

exports.url = functions.https.onRequest((requested, response) => {

    var uri = requested.url;
    request({
        uri: uri,
        followRedirect: true
      },
      function(err, httpResponse) {
        if (err) {
          return console.error(err);
        }
        response.send(httpResponse.headers.location || uri);
      }
    );

});

Result

When I go to myapp.firebaseappurl.com/url/SHORTENEDLINK I get the following:

Error: could not handle the request

解决方案

Did you tried using { source: '/url/**' } syntax?

You can use something like this;

{
  "hosting": {
    "public": "public",
    "rewrites": [ {
    "source": "/url/**",
    "function": "/url"
    }]
  }
}

and then you can parse the url from the request.

 exports.url = functions.https.onRequest((req, res) => { 
   // parse the url from the req and redirect to the correct link
 });
