我正在开发一个网站，用户可以在其中添加其他列表链接。我正在尝试进行设置，以便当用户向Google上的某个地点添加链接时（例如从Google地图中抓取共享链接：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），然后我可以使用Google Places API提取其他信息。
但是，Google Places API需要您指定地点ID，我想知道是否有办法从提供的地图网址获取此地址？我知道你可以从这里手动获取它：https://developers.google.com/maps/documentation/javascript/examples/places-placeid-finder但是以某种方式通过地图URL获取地方ID？
谢谢！
答案 0 :(得分：1)
可能有点晚了，但我想尝试一下......
背景资料：
This answer建议您通过将地点cid（与placeId不同）传递给Places API Web Service来获取地点详细信息。
这会使用未记录的查询参数，因此，使用它需要您自担风险。这可能会在没有警告的情况下随时停止工作！
This article建议您从地图网址中提取cid。
然后我发现this code snippet有助于解析Google地图网址中的data属性。
不幸的是，您不能将Places API Web服务与AJAX调用一起使用，因为您将遇到CORS问题，因此您需要使用其他方法。并且您无法使用Google Maps Javascript API的地方资料库，因为它要求您传递placeId并且不接受cid。这就是我必须使用PHP从Web服务中获取结果的原因。
要运行以下代码，您还需要jQuery，或者您需要替换$.ajax(...)函数，并且需要在Web服务请求中使用您自己的API密钥替换<your_api_key>（PHP码）。
所以我们走了......这是Javascript：
function mapsUrlToPlaceDetails(url) {
var re = /data=(.*)/;
var data = url.match(re);
var str = data[1];
var parts = str.split('!').filter(function (s) {
return s.length > 0;
}),
root = [], // Root elemet
curr = root, // Current array element being appended to
m_stack = [root,], // Stack of "m" elements
m_count = [parts.length,]; // Number of elements to put under each level
parts.forEach(function (el) {
var m = /^(\d+)(\w)(.*)$/.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));
以下是get_place_details.php页面：
<?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;
}

答案 1 :(得分：0)
你无法从URL获取place_id，你提到的placeid finder实际上是一个使用GM Javascript API的自动完成服务来获取它们的应用程序。
解决方法是从URL获取坐标（您可以这样做）然后使用自动填充服务或地理编码器来获取place_id（来自从URL获取的坐标）
