安卓设备微信小程序,在video播放视频时,传递了一个 content-type:空字符串. 导致oss端验签失败.

浏览器,ios手机,微信开发者工具,都没有这个问题.

GET

/test2b/out.mp4

x-oss-credential=LTAI5t7eZR5NtpQ2o3j6va4f%2F20250519%2Fcn-hangzhou%2Foss%2Faliyun_v4_request&x-oss-date=20250519T031830Z&x-oss-expires=604800&x-oss-signature-version=OSS4-HMAC-SHA256

content-type:

UNSIGNED-PAYLOAD

经过测试,签名时主动加上content-type空字符串, 安卓设备微信小程序video就可以正常播放了.

$options = array(

OssClient::OSS_CONTENT_TYPE => '',

);

$ossClient = new OssClient($config);

return $ossClient->signUrl('test2b', $object, 32400, 'GET',$options);

修改OssClient.php

foreach ($headers as $header_key => $header_value) {

$header_value = trim($header_value);

// if (empty($header_value)) {

// continue;

// }

$request->add_header($header_key, $header_value);

}
