如何从 Google 地图 URL 获取 Google Place ID (placeId)

Question

I am working on a site where users are able to add additional links for listings. I am trying to set it up such that when a user adds a link to a place on Google (for example grabbing the share link from Google Maps: https://www.google.com/maps/place/Twin+Elephant+Brewing+Company/@40.7290336,-74.3828372,17z/data=:4m5.3m4.1s0x89c3afa1b597fe49:0x890cb024fe77e7b6!8m2!3d40.7290336!4d-74.3806485 ) I can then use the Google Places API to pull in additional info.

However, the Google Places API needs you to specify the place ID and I am wondering if there is a way to get this from a provided Maps URL? I know you can manually get it from here: https://developers.google.com/maps/documentation/javascript/examples/places-placeid-finder but is there to somehow grab the Place ID via the maps URL?

Thanks!

Answer 1

Probably a bit late on this but I wanted to give it a try...

Background information:

This answer suggests that you can get a place details by passing the place cid (which is not the same thing as the placeId ) to the Places API Web Service .

This makes use of an undocumented query parameter therefore, use it at your own risks . That might stop working at any time without warning!

This article suggests that you can extract the cid from a Maps URL.

I then found this code snippet that helps parsing the data attribute in a Google Maps URL.

Unfortunately, you cannot use the Places API Web Service with an AJAX call as you will run into CORS issues, so you need to use another method. And you cannot use the Places Library of the Google Maps Javascript API as it requires you to pass the placeId and won't accept a cid . That's why I had to use PHP to grab the results from the web service.

To run the below code, you will also need jQuery, or you will need to replace the $.ajax(...) function and you need to replace <your_api_key> with your own API key in the web service request (PHP code).

So here we go... here is the Javascript:

function mapsUrlToPlaceDetails(url) {

    var re = /data=(.*)/;

    var data = url.match(re);

    var str = data[1];

    var parts = str.split('!').filter(function (s) {
            return s.length > 0;
        }),
        root = [], // Root elemet
        curr = root, // Current array element being appended to
        m_stack = [root,], // Stack of "m" elements
        m_count = [parts.length,]; // Number of elements to put under each level

    parts.forEach(function (el) {

        var m = /^(\d+)(\w)(.*)$/.exec(el),
            idx = m[1],
            kind = m[2],
            value = m[3];

        // Decrement all the m_counts
        for (var i = 0; i < m_count.length; i++) {
            m_count[i]--;
        }

        if (kind === 'm') { // Add a new array to capture coming values
            var new_arr = [];
            m_count.push(value);
            curr.push(new_arr);
            m_stack.push(new_arr);
            curr = new_arr;
        } else {
            if (kind == 'b') { // Assuming these are boolean
                curr.push(value == '1');
            } else if (kind == 'd' || kind == 'f') { // Float or double
                curr.push(parseFloat(value));
            } else if (kind == 'i' || kind == 'u' || kind == 'e') { // Integer, unsigned or enum as int
                curr.push(parseInt(value));
            } else { // Store anything else as a string
                curr.push(value);
            }
        }

        // Pop off all the arrays that have their values already
        while (m_count[m_count.length - 1] === 0) {
            m_stack.pop();
            m_count.pop();
            curr = m_stack[m_stack.length - 1];
        }
    });

    var enc = root[0][0][0];

    // Find the CID with a regex
    re = /:0x(.*)/;
    var cMatch = enc.match(re);

    // We have the place CID as hexadecimal, we convert it to decimal in our PHP script
    var cid = cMatch[1];

    var serviceData = false;

    // Query our PHP page with our CID
    $.ajax({
        type: 'GET',
        url: 'get_place_details.php',
        data: {
            cid: cid
        },
        success: function (data) {

            if (data) {

                serviceData = data;
            }
        },
        async: false,
        contentType: "application/json",
        dataType: 'json',
    });

    return serviceData;
}

var url = 'https://www.google.com/maps/place/Twin+Elephant+Brewing+Company/@40.7290336,-74.3828372,17z/data=!4m5!3m4!1s0x89c3afa1b597fe49:0x890cb024fe77e7b6!8m2!3d40.7290336!4d-74.3806485';

console.log(mapsUrlToPlaceDetails(url));

---

And here is the get_place_details.php page:

<?php
header('Content-Type: application/json');

// Get the hexadecimal CID
$hexString = $_GET['cid'];

// Convert it to decimal
$decString = bchexdec($hexString);

// Query the web service
$url = 'https://maps.googleapis.com/maps/api/place/details/json?cid=' . $decString . '&key=<your_api_key>';
$json = file_get_contents($url);

// Print results
print $json;

// Convert hexadecimal CID to decimal
function bchexdec($hex) {

  $len = strlen($hex);
  for ($i = 1; $i <= $len; $i++)
    $dec = bcadd($dec, bcmul(strval(hexdec($hex[$i - 1])), bcpow('16', strval($len - $i))));

  return $dec;
}

Hope this helps but again: use at your own risks!

Answer 2

You can not get a place_id from a URL, the placeid finder that you mention is actually an app that uses the autocomplete services of the GM Javascript API to get them.

A workaround would be getting coordinates from the URL (this you can do) and then use either Autocomplete service or geocoder to get the place_id (from the coordinates gotten from URL)

Answer 3

I'd like to share my solution although it's been 3 years.

The best for me is to work with google maps url that already specified the place. It needs 2 steps.

1. Extract place name from the url string between '/maps/place/' and '@'.
2. Search the extracted place name using google place textsearch. Put it in 'query' as explained HERE and you will get details for the place including place_id

Answer 4

curl -X POST 'https://ruriazzfree.vercel.app/api/scrape/gplace' \
     -H 'Content-Type: application/json' \
     -d '{"gmap_link": "https://goo.gl/maps/DMMAakiA6nZrq9TE7"}'
