I've got this issue, PHP and Laravel. I'm trying to read a JSON file from remote ULR:

https://services.realestate.com.au/services/listings/search?query={"channel":"buy","filters":{"propertyType":["house"],"surroundingSuburbs":"False","excludeTier2":"true","geoPrecision":"address","localities":[{"searchLocation":"Blacktown, NSW 2148"}]},"pageSize":"100"}

I used the code:

$re_url = 'https://services.realestate.com.au/services/listings/search?query={"channel":"buy","filters":{"propertyType":["house"],"surroundingSuburbs":"False","excludeTier2":"true","geoPrecision":"address","localities":[{"searchLocation":"Blacktown, NSW 2148"}]},"pageSize":"100"}';

$ch = curl_init($re_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$re_str = curl_exec($ch);
$re_list = json_decode($re_str);

It kept receiving Error "An error occurred while processing your request. Reference #30.96464868.1492255689.1829cf2"

I tried url with "https://google.com.au", which worked ok, so it looks like the URL encode issue. But I'm not sure.

Can anyone help, or had the same issues?

    I believe you have two issues and that my code below will solve them. My code also uses a few different methodologies to avoid manual assembly of JSON, URL query strings, etc. (see lines 3-41 of the provided code)


    1. You are not encoding the query parameter values - can be fixed with urlencode of the param values, but I prefer http_build_query for reasons noted in my introductory paragraph.
    2. You are not sending a User Agent (UA) header (The distant end seems to require a value in this header but doesn't care what it is. Having received a request with a UA I think it must whitelist the IP for a few moments as it doesn't seem to require it on every request. I would just send it for every request, though, as it doesn't hurt and you never know when your whitelist will timeout). See lines 50-53 for what I set in this script and some options you have

    Replacement Code

    With explanatory comments

     * The data that will be serialized as JSON and used as the value of the
     * `query` parameter in your URL query string
    $search_query_data = [
        "channel" => "buy",
        "filters" => [
            "propertyType" => [
            "surroundingSuburbs" => "False",
            "excludeTier2" => "true",
            "geoPrecision" => "address",
            "localities" => [
                    "searchLocation" => "Blacktown, NSW 2148",
        "pageSize" => "100",
     * Serialize the data as JSON
    $search_query_json = json_encode($search_query_data);
     * Make a URL query string with a param named `query` that will be set as the
     * JSON from above
    $url_query_string = http_build_query([
        'query' => $search_query_json,
     * Assemble the URL to which we'll make the request, and set it into CURL
    $request_url = 'https://services.realestate.com.au/services/listings/search?' . $url_query_string;
    $ch = curl_init($request_url);
     * Set some CURL options
    // Have `curl_exec()` return the transfer as a string instead of outputting
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    // Set a user agent header
    curl_setopt($ch, CURLOPT_USERAGENT, 'H.H\'s PHP CURL script');
    // If you want to spoof, say, Safari instead, remove the last line and uncomment the next:
    //curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_4) AppleWebKit/603.1.30 (KHTML, like Gecko) Version/10.1 Safari/603.1.30');
     * Get the response and close out the CURL handle
    $response_body = curl_exec($ch);
     * Unserialize the response body JSON
    $search_results = json_decode($response_body);

    Finally, as an aside, I would recommend you stop using CURL directly and start using a library to abstract away some of the HTTP interactions and to make your requests/responses start to fit better with "standard" (PSR) interfaces. Since you're using Laravel, you're already in an ecosystem with Composer, so you could easily install something like Guzzle.
