淘宝买家秀、PHP版本-sign值的生成

很早之前发到知乎上边的!!!感兴趣的可以看看

网上找了很多关于买家秀sign值的生产、找到的是Python版本的!

由于本人擅长的PHP语言,这必须得翻译成PHP版本的呀!!

那就来吧、用到的Laravel8框架、类库: HTTP客户端库( guzzlehttp/guzzle )

一、安装HTTP客户端库:

composer require guzzlehttp/guzzle

二、分析请求参数、接口:

接口地址:https://acs.m.taobao.com/h5/mtop.taobao.social.feed.aggregate/1.0/
appKey: 12574478
t: 1560094920983
sign: 9fd51773ab6c80205f4a0c2f97ca14c6
api: mtop.taobao.social.feed.aggregate
v: 1.0
timeout: 300000
timer: 300000
type: jsonp
dataType: jsonp
callback: mtopjsonp1
data: {"params":"{\"nodeId\":\"\",\"sellerId\":\"50852803\"}","cursor":"1","pageNum":"1","pageId":5703,"env":"1"}

其中 t (就是一个时间戳而已) 和 sign是动态生成的。其他都为固定字段!

t 我封装成一个方法,直接调用即可:

    /**
     * @copyright 获取时间戳
     * @Author    不问归期_:2019-12-16
     * @param     boolean          $digits [description]
     * @return    [type]                   [description]
     */
    public function getTimestamp($digits = false)
    {
        $digits = $digits > 10 ? $digits : 10;
        $digits = $digits - 10;
        if ((!$digits) || ($digits == 10)) {
            return time();
        } else {
            return number_format(microtime(true), $digits, '', '');
        }
    }

sign 是通过cookies中的参数生成的、直接上代码吧

$url = 'https://acs.m.taobao.com/h5/mtop.taobao.social.feed.aggregate/1.0/?appKey=12574478';
$client = new Client(array(
    'cookies' => true
));
$response = $client->request('GET', $url);
$Cookie = $response->getHeader('Set-Cookie');
$_m_h5_tk = Str::before(Str::after($Cookie[1], '_m_h5_tk='), '_');
$_m_h5_tk_enc = Str::before(Str::after($Cookie[2], '_m_h5_tk_enc='), ';');
$times = $this->getTimestamp(13);
$data = '{"params":"{\"sellerId\":\"50852803\",\"pagination\":{\"pageNum\":\"1\",\"pageSize\":\"6\"}}","pageId":5703}';
//$cookie = preg_replace('/\s/', '', '_m_h5_tk=' . $_m_h5_tk . '; _m_h5_tk_enc=' . $_m_h5_tk_enc);
$sign = md5($_m_h5_tk . '&' . $times . '&12574478&' . $data);

这两个动态参数都能获取了、接下来就是请求参数拼接并请求数据了!

$url = $url . '&t=' . $times . '&sign=' . $sign . '&data=' . $data;
$res = $client->request('GET', $url);
$res =  $res->getBody()->getContents();
dump($res);

成功!!

三、一些细节处理

我们看data这个参数并分析一下

$data = '{"params":"{\"sellerId\":\"50852803\",\"pagination\":{\"pageNum\":\"1\",\"pageSize\":\"6\"}}","pageId":5703}';

其中sellerId 就是卖家秀id 、pageNum 就是页数(就是获取第几页的数据) 、pageSize 就不用多说了吧.(这里不说了,不懂的就自行测试吧) data这个参数主要的就是这三个参数了.

优化后的代码:

$sellerId = $request->input('sellerId');
$pageNum = $request->input('pagenum', 1);
$pageSize = $request->input('pagesize', 5);
$url = 'https://acs.m.taobao.com/h5/mtop.taobao.social.feed.aggregate/1.0/?appKey=12574478';
$client = new Client(array(
    'cookies' => true
));
$response = $client->request('GET', $url);
$Cookie = $response->getHeader('Set-Cookie');
$_m_h5_tk = Str::before(Str::after($Cookie[1], '_m_h5_tk='), '_');
$_m_h5_tk_enc = Str::before(Str::after($Cookie[2], '_m_h5_tk_enc='), ';');
$times = $this->getTimestamp(13);
$data = '{"params":"{\"sellerId\":\"' . $sellerId . '\",\"pagination\":{\"pageNum\":\"' . $pageNum . '\",\"pageSize\":\"' . $pageSize . '\"}}","pageId":5703}';
//$cookie = preg_replace('/\s/', '', '_m_h5_tk=' . $_m_h5_tk . '; _m_h5_tk_enc=' . $_m_h5_tk_enc);
$sign = md5($_m_h5_tk . '&' . $times . '&12574478&' . $data);
$url = $url . '&t=' . $times . '&sign=' . $sign . '&data=' . $data;
$res = $client->request('GET', $url);
$res =  $res->getBody()->getContents();
dump($res);

好了!!!以上就是全部代码、、

四、最后附上完整代码:

<?php

namespace App\Http\Controllers;

use GuzzleHttp\Client;
use Illuminate\Support\Str;
use Illuminate\Http\Request;

     */
    public function index(Request $request)
    {
        $sellerId = $request->input('sellerId');
        $pageNum = $request->input('pagenum', 1);

        $client = new Client(array(
            'cookies' => true
        ));
        $response = $client->request('GET', $url);
        $Cookie = $response->getHeader('Set-Cookie');
        $_m_h5_tk = Str::before(Str::after($Cookie[1], '_m_h5_tk='), '_');
        $_m_h5_tk_enc = Str::before(Str::after($Cookie[2], '_m_h5_tk_enc='), ';');
        $times = $this->getTimestamp(13);

        //$cookie = preg_replace('/\s/', '', '_m_h5_tk=' . $_m_h5_tk . '; _m_h5_tk_enc=' . $_m_h5_tk_enc);
        $sign = md5($_m_h5_tk . '&' . $times . '&12574478&' . $data);
        $url = $url . '&t=' . $times . '&sign=' . $sign . '&data=' . $data;
        $res = $client->request('GET', $url);

     */
    public function getTimestamp($digits = false)
    {
        $digits = $digits > 10 ? $digits : 10;
        $digits = $digits - 10;
        if ((!$digits) || ($digits == 10)) {
            return time();
        } else {
            return number_format(microtime(true), $digits, '', '');
        }
    }
}
