Sub path is not working...

[ShawnBaek]

I have a simple question.

Is this library support sub path?

I want to access json data using url like below

https://public-api.wordpress.com/rest/v1.1/sites/uxengineer.wordpress.com/posts

app.use(
    '/api', 
    proxy('https://public-api.wordpress.com/rest/v1.1/sites/uxengineer.wordpress.com', {
        proxyReqOptDecorator(opts) {
            opts.headers['x-forwarded-host'] = 'localhost:3000';
            return opts;
        }
    })
);

I tried to access http://localhost:3000/api/posts but It is not working

{ "error": "not_found", "message": "The specified path was not found. Please visit https://developer.wordpress.com/docs/ for valid paths." }

I changed like below and It works fine

app.use(
    '/api', 
    proxy('https://public-api.wordpress.com', {
        proxyReqOptDecorator(opts) {
            opts.headers['x-forwarded-host'] = 'localhost:3000';
            return opts;
        }
    })
);

This is working fine...

http://localhost:3000/api/rest/v1.1/sites/uxengineer.wordpress.com/posts

The result is

{"ID":152056136,"name":"ShawnBaek","description":"","URL":"https:\/\/uxengineer.wordpress.com","jetpack":false,"subscribers_count":1,"lang":false,"logo":{"id":0,"sizes":[],"url":""},"visible":null,"is_private":false,"is_following":false,"meta":{"links":{"self":"https:\/\/public-api.wordpress.com\/rest\/v1.1\/sites\/152056136","help":"https:\/\/public-api.wordpress.com\/rest\/v1.1\/sites\/152056136\/help","posts":"https:\/\/public-api.wordpress.com\/rest\/v1.1\/sites\/152056136\/posts\/","comments":"https:\/\/public-api.wordpress.com\/rest\/v1.1\/sites\/152056136\/comments\/","xmlrpc":"https:\/\/uxengineer.wordpress.com\/xmlrpc.php"}}}

My question is

Why proxy url with sub path is not work ?

How to solve this problem?

Can confirm this is also an issue for me.

I experienced this issue, too, but I think this may be a misunderstanding with how express-http-proxy works. The idea is that you can forward a given path to a given host. Any subpath after that specified path will be added to the host request. For example, doing app.use('/foo', 'http://google.com' will proxy requests to just http://google.com when the user goes to the route /foo. However, when the user goes to /foo/bar, it'll proxy http://google.com/bar.

To get around this (if you want an entire path to be forwarded instead), do something like the following:

app.use('/foo', proxy('google.com', {
  proxyReqPathResolver: function(req) {
    return '/foo';
  }
});

Note that this means /foo/bar will go to google.com/foo.

@ShawnBaek you can use proxyReqPathResolver to include the fixed path, so when you send a request to http://localhost:3000/api/post, it will become host + fixed path + your request url (which does not include the /api)

app.use(
  '/api',
  proxy('https://public-api.wordpress.com', {
    proxyReqPathResolver: function(req) {
      return '/rest/v1.1/sites/uxengineer.wordpress.com' + req.url;
    }
  })
);
