Google Places API - 查找公司的CID和LRD [英] Google Places API - Find a company's CID and LRD

问题描述

有人知道如何使用Google Places API找到公司的CID和/或LRD吗？

到目前为止，我提出的最佳解决方案是：

1. 转至 https：// maps.google.com 并搜索业务


2. 在浏览器的URL中找到 data 参数并提取组件它符合以下模式： 0x [HEX_CODE1]：0x [HEX_CODE2]


3. 我们刚刚提取的两部分数字是公司的LRD 。现在，从该数字中取 HEXCODE_2 并将十六进制转换为十进制数。这给了我们公司的CID。

很明显，这个过程并没有得到谷歌官方的支持，如果我需要，为许多企业做到这一点。是否有人有更好的方法？

两个API请求，您将以编程方式获得业务的CID。

LRD是十六进制的CID。你可以使用这个函数：

pre $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ （'0'，'1'，'2'，'3'，'4'，'5'，'6'，'7'，
'8'，'9'，'A'，' B， 'C'， 'd'， 'E'， 'F'）;
$ hexval ='';
while（$ number！='0'）
{
$ hexval = $ hexvalues [bcmod（$ number，'16'）]。$ hexval;
$ number = bcdiv（​​$ number，'16'，0）;
}
返回$ hexval;
}

因此，您可以像这样构建Google Review网址：

  $ business_url =https://www.google.com/search?q=NAMEOFBUSINESS&ludocid=YOURCID#lrd=0x0:0xYOURHEXCID,1 ; 
  

Does anybody know how to find a company's CID and/or LRD using the Google Places API?

The best solution I've come up with so far is this:

1. Go to https://maps.google.com and search for the business
2. Find the data parameter in the browser's URL and extract the component that matches this pattern: 0x[HEX_CODE1]:0x[HEX_CODE2]
3. The 2-part number we just extracted is the company's LRD. Now, take HEXCODE_2 from that number and convert the hex to decimal. This gives us the company's CID.

Obviously this process isn't officially supported by Google, and wouldn't scale well if I needed to do it for many businesses. Does anybody have a better method?

Read this article to obtain the CID: How to get the cid in the Google Place URL?

Two API requests and you'll have the CID of a business programmatically.

EDIT ----------

The LRD is CID in hexadecimal. You can use this function to:

function dec2hex($number)
{
    $hexvalues = array('0','1','2','3','4','5','6','7',
               '8','9','A','B','C','D','E','F');
    $hexval = '';
     while($number != '0')
     {
        $hexval = $hexvalues[bcmod($number,'16')].$hexval;
        $number = bcdiv($number,'16',0);
    }
    return $hexval;
}

So you can build the Google Review Url like this:

$business_url = "https://www.google.com/search?q=NAMEOFBUSINESS&ludocid=YOURCID#lrd=0x0:0xYOURHEXCID,1";
