Sharing tips on how to use PHP and phpSpider to capture Sina Weibo data!

With the development of the Internet, social media platforms have become an important way for people to obtain information and communicate. As one of China's largest social media platforms, Sina Weibo has a large user base and rich information resources. If Sina Weibo data can be obtained, it will be of great significance for business analysis, public opinion monitoring and other work. This article will introduce how to use PHP and phpSpider to capture Sina Weibo data. I hope to provide you with some tips and methods.

First, we need to install and configure phpSpider.

phpSpider is an open source web crawling framework based on PHP, which can be used to quickly build a powerful web crawler system. We can use phpSpider to crawl Sina Weibo pages and parse the data.

First, we need to install Composer. Composer is a PHP package management tool that can be used to install phpSpider and other required dependent libraries. Execute the following command in the command line to install Composer:

curl -sS https://getcomposer.org/installer | php
mv composer.phar /usr/local/bin/composer

After the installation is complete, we can use Composer to install phpSpider. Execute the following command in the command line:

composer require dcb9/phpspider

After the installation is complete, we need to create a new PHP file, such as named weiboSpider.php, to write our crawling code.

First, we import the phpSpider library and write the following code:

require 'vendor/autoload.php';

use phpspidercorephpspider;
use phpspidercoreequests;
use phpspidercoreselector;
use phpspidercorelog;
use phpspidercoreutil;

$target_weibo_id = "1234567890"; // 新浪微博的id

// 设置日志目录
log::$log_file = dirname(__FILE__).'/log.log';

// 爬虫的基本配置
$configs = array(
    'name' => 'weiboSpider',
    'log_show' => false, // 是否显示日志
    'log_file' => dirname(__FILE__).'/data.log', // 日志文件保存的路径
    'tasknum' => 1, // 并发数
    'interval' => 1000, // 爬取间隔，单位毫秒
);

// 实例化爬虫对象
$spider = new phpspider($configs);

// 设置请求的header
$spider->on_start = function($spider) use ($target_weibo_id)
{
    $headers = array(
        'User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/89.0.4389.82 Safari/537.36',
        'Cookie: your_cookie', // 替换成你的新浪微博Cookie
    );
    requests::set_header($headers);
    $url = "https://weibo.com/u/{$target_weibo_id}?profile_ftype=1&is_all=1#_0";
    $spider->add_url($url);
};

// 正则匹配微博数据
$spider->on_extract_page = function($page, $data) use ($target_weibo_id)
{
    $weibo_id = '';
    $content = '';
    $time = '';

    $selector = "//div[@class='WB_detail']/div[@class='WB_text']";
    $content = selector::select($content_html, $selector);
    $selector = "//div[@class='WB_detail']/div[@class='WB_from S_txt2']";
    $time = selector::select($content_html, $selector);

    $data['weibo_id'] = $weibo_id;
    $data['content'] = $content;
    $data['time'] = $time;

    return $data;
};

// 开始抓取
$spider->start();

In the above code, we first import the phpSpider library, and then define the id of Sina Weibo that needs to be crawled , and set the log directory and basic configuration. Next, we set the request header and the url to start crawling by setting the on_start callback function. Then the on_extract_page callback function is defined to extract the Weibo data in the returned page. Finally, call the start() method to start crawling.

In the above code, you need to replace the cookie with your Sina Weibo cookie, which can be obtained by viewing the cookie after logging into Sina Weibo in the browser.

Through the above code examples, we can capture and parse the data of Sina Weibo. Of course, the crawling rules and data parsing rules for specific pages will be adjusted according to actual needs.

To summarize, using PHP and phpSpider can quickly capture Sina Weibo data. Through the above sample code, you can further customize and expand it according to your own needs to achieve more complex functions. I hope this article will be helpful to everyone on Sina Weibo data crawling techniques!
