php – Google测量协议返回GIF89a ,D;

作者:互联网

我正在使用Google Measurement协议API保存展示次数.它工作正常,但虽然我没有回应任何东西它返回GIF89a ,D;这在页面上可见.知道如何隐藏这个吗?

我正在使用HTTP post请求发送数据.

$url = 'http://www.google-analytics.com/collect';
$fields_string = '';
$fields = array(
    'v' => 1,
    'tid' => 'UA-xxxxxxx-xx',
    'cid' => xxx,
    't' => 'event',
    'ec' => 'category',
    'ea' => 'impression',
    'el' => 'label'
);

foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
rtrim($fields_string, '&');

$ch = curl_init();

curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, count($fields));
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);

$result = curl_exec($ch);
curl_close($ch);

解决方法:

就目前而言,在进行cURL调用时,返回的信息将显示在屏幕上.如果你想避免使用CURLOPT_RETURNTRANSFER,那么你可以将返回的信息存储到变量中.

$result = curl_exec($ch);

因为你没有“告诉”卷曲,否则它只会将返回溢出到浏览器.

所以最后,你卷曲部分应该像这样:

$ch = curl_init();
curl_setopt($ch,CURLOPT_URL, $url); //curl the url
curl_setopt($ch,CURLOPT_POST, count($fields));
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);
curl_setopt($ch,CURLOPT_RETURNTRANSFER, TRUE); //return the transfer to be later saved to a variable
$result = curl_exec($ch);
