ajax獲取不到php方法里curl請求的數(shù)據(jù)。直接通過url地址訪問可以獲取數(shù)據(jù)。

通過url直接訪問php方法里一個跨域請求可以得到數(shù)據(jù)，但是用ajax請求返回的結(jié)果為空。

php 代碼

    $host = "xxx.xxxx.cn/Home/Index/index"; 
    // $header[] = "Content-type: text/xml;charset=UTF-8";
    // $ch = curl_init();
    $ch = curl_init($host); 
    curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($host));    //參數(shù)
    curl_setopt ( $ch, CURLOPT_SSL_VERIFYPEER, false );
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
    curl_setopt($ch, CURLOPT_TIMEOUT,5);
    $arra = curl_exec($ch);
    curl_close($ch);
    $arra = json_decode($arra,true);
    foreach ($recommend as $value) {    
        foreach ($arra as $v) {
            if ($value['id'] == $v['shop_id']) {
                $rmd[]=array_merge_recursive($value,$v);
            }
        }
    }
    if (count($rmd) < count($recommend)) {
        $diff = array_diff_key($recommend,$rmd);
        foreach ($diff as $val) {
            $pageview['pageview'] = 0;
            $aa[] = array_merge_recursive($value,$pageview);
        }
    }
    $recommends =array_merge_recursive($aa,$rmd);
    // var_dump($recommends);   
    return $this->ajaxReturn($recommends , 1, 1);

ajax
$.ajax({

            type: "POST",
            dataType: "json",
            url: "{:U('Shop/Site/GetRecommend')}",
            data: null,
            success: function(result) {
            //這里得到的結(jié)果為空
                console.log(result) 
        });

被折磨一天了，完全不清楚是什么原因。
