Answer 1

检查 页面输出的header 的 content-type 的类型

还有，提醒一下你这样暴露appid和secret真的好吗

Answer 2

$type = getimagesize($huanurl);//取得图片的大小，类型等
$content = gettoken($huanurl);
$file_content = chunk_split(base64_encode($content));//base64编码
echo $file_content;
switch ($type[2]) {//判读图片类型

case 1:
    $img_type = "gif";
    break;
case 2:
    $img_type = "jpg";
    break;
case 3:
    $img_type = "png";
    break;

}
$img = 'data:image/' . $img_type . ';base64,' . $file_content;//合成图片的base64编码
echo "<img src='" . $img . "'>";
