这个URL需要urlencoding在哪里？

Question

I hosted a website i worked on on amazon web services, and for some reason some things dont work compared to when I run it locally on localhost.

of those things are the

if (array_key_exists("error", $json))

function and

the file_get_contents function.

Ive commented out the array key exists part and that solved the issue, at least for that part of logging in, until i get to the view documents page where a slim application error displays

failed to open stream: HTTP request failed! HTTP/1.1 404 Not Found

and the issue for that lies in the viewdocspage.php file, particularly this code:

<?php
                 $raw = file_get_contents("http://cosoft.us-east-1.elasticbeanstalk.com/cosoft/mywiki/api.php?action=query&list=allpages&format=json");
                 $pages_response = json_decode($raw, true);
                 $pages_array = $pages_response["query"]["allpages"];
                 $page_titles = [];

I looked and read up on many threads that the issue lies with the file_get_contents in which the URL contains special characters, such as spaces (which mine doesnt have) and so needs to be encoded, using urlencode (or rawurlencode..?)

now ive tried encoding the whole url like this:

$raw = file_get_contents(urlencode("http://cosoft.us-east-1.elasticbeanstalk.com/cosoft/mywiki/api.php?action=query&list=allpages&format=json"));

but that resulted in this error: slim error

Message: file_get_contents(http%3A%2F%2Fcosoft.us-east-1.elasticbeanstalk.com%2Fcosoft%2Fmywiki%2Fapi.php%3Faction%3Dquery%26list%3Dallpages%26format%3Djson): failed to open stream: No such file or directory

---

I figured that this may happen since I read that not all the URL should be wrapped by this encoding, but heres where Im stuck: which part of the url do i use the encoding on? the only special characters i keep coming accross regarding this error is spaces, but i dont have any spaces, so its something else which i dont know what it is...

Help is appreciated, thanks!

You would just need to url_encode the parameters. Say you had a value $value='My name is earl' If you wanted to pass this value as a parameter in your url http://somesite.com/?name=$value there would be spaces in the value that is url_encoded. So if you encode it as 'http://somesite.com/?name='.urlencode($value), when this is encoded the value will turn into My+name+is+earl
