<!--?php
$cookie_file=tempnam('./temp','cookie');
$login_url='https://account.xiaomi.com/pass/serviceLoginAuth';
$post ='user&pwd=&sid=eshop&callback=http%3A%2F%2Forder.xiaomi.com%2Flogin%2Fcallback%3Ffollowup%3Dhttp%253A%252F%252Fwww.xiaomi.com%252F%26sign%3DMjk4NmVlYzNiOWY5YTkwMjExNzg5MjkyNzE3ZmIxOGM4YTBiMDk1Mg%2C%2C&_sign=f%2FKB8SAfmaLZ0s28kcLtBSmZlEM%3D&_json=true'//避免不必要的麻烦 post的具体帐号密码去掉了
$ch=$curl=curl_init($login_url);
curl_setopt($ch,CURLOPT_HEADER,0);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,0);
curl_setopt($ch,CURLOPT_POST,1);
curl_setopt($ch,CURLOPT_COOKIEJAR,$cookie_file);

把第十九行删除了

<!--?php    $url="http://www.xiaomi.com/index.php";    $ch=curl_init($url);    curl_setopt($ch,CURLOPT_HEADER,0);    curl_setopt($ch,CURLOPT_RETURNTRANSFER,0);    //curl_setopt($ch,CURLOPT_COOKIEFILE,$cookie_file);    echo $contents=curl_exec($ch);    curl_close($ch);</pre-->  <br> 测试成功 <p></p> <p class="sougouAnswer">  可是这样就没达到模拟帐号登陆的效果呀。只是采集了xiaomi的主页。 </p> <p class="sougouAnswer">  那说明还有数据没有提交。例如：  <br> curl_setopt($ch, CURLOPT_REFERER,  <br> post的数据不全：  <br> 两周内自动登录的input标志：auto=1  <br> 网页里面表单的其它值等。  <br> </p> <p class="sougouAnswer">  $login_url='https://account.xiaomi.com/pass/serviceLoginAuth';  <br> 应为：  <br> $login_url='https://account.xiaomi.com/pass/serviceLoginAuth2'; </p> <p class="sougouAnswer">  </p><pre class="sycode layui-box layui-code-view layui-code-notepad" name="code"><ol class="layui-code-ol"><li></li></ol></pre>  <br> 里面所有<input type="hidden" <br=""> 的值，其中passToken可能是使用js生成的。 <p></p> <p class="sougouAnswer">  感谢大神提供思路，我再试试看~                    </p>
