How does ThinkPHP get the publisher address annotation (two methods)

When developing websites such as social networks and e-commerce platforms, it is often necessary to obtain the publisher's address annotation so that users can understand the geographical location of the publisher. In ThinkPHP, there are many ways to obtain the publisher address annotation. This article will introduce the most commonly used methods.

1. Use the IP address to obtain the publisher address annotation

When obtaining the publisher address annotation, you can use its IP address for positioning. In ThinkPHP, you can obtain the IP address of the current request through the getRequest() method, and then use third-party geolocation services (such as Baidu Map API) to analyze and obtain the corresponding geolocation information.

Code example:

// 获取当前请求的 IP 地址
$client_ip = request()->ip();
// 利用百度地图 API 获取地理位置信息
$url = "http://api.map.baidu.com/location/ip?ak=您的密钥&ip=$client_ip&coor=bd09ll";
$result = file_get_contents($url);
$location = json_decode($result, true);
$address = $location['content']['address'];

Among them, the $client_ip variable stores the IP address of the current request, and the $url variable stores the URL for calling the Baidu Map API Address, $result variable stores the parsing result, $location variable is the array form of the parsing result, $address variable stores the finally obtained address annotation information.

2. Use browser positioning to obtain the publisher's address annotation

In addition to using the IP address to obtain the address annotation, you can also use browser positioning to obtain the address annotation. In ThinkPHP, you can use JavaScript to obtain the browser location, and then use third-party geolocation services (such as Tencent Map API) to analyze and obtain the corresponding address annotation information.

Code example:

// 页面中引入 JavaScript 定位代码
navigator.geolocation.getCurrentPosition(function(position) {
    // 获取浏览器定位的经纬度
    var lat = position.coords.latitude;
    var lng = position.coords.longitude;
    // 利用腾讯地图 API 获取地理位置信息
    var url = "https://apis.map.qq.com/ws/geocoder/v1/?location=" + lat + "," + lng + "&key=您的密钥&get_poi=0";
    $.ajax({
        url: url,
        dataType: "jsonp",
        success: function(result) {
            // 解析结果，获取地址标注信息
            var address = result.result.formatted_addresses.recommend;
        }
    })
});

Among them, the navigator.geolocation.getCurrentPosition() method obtains the browser positioning, lat and lng Variables store the obtained longitude and latitude information. url Variables store the URL address for calling Tencent Map API. success The code in the parameter obtains the parsing results and obtains the final address annotation information.

3. Summary

The above are two common methods to obtain publisher address annotation in ThinkPHP. Different methods are suitable for different scenarios and need to be selected according to specific needs. When using third-party geolocation services, you need to register a developer account first and obtain the corresponding key to ensure normal API calls.
