我有一些 php 代码可以很好地使用 cURL 将文件上传到仅使用用户和密码 ftp 的主机,现在我必须上传到只允许公钥身份验证的服务器并且收到错误:“* SSH 公钥身份验证失败:回调返回错误”
我的密钥有问题,因为它们的格式不正确,但后来将它们放入正确的单行格式,这阻止了“非 base64 编码”错误。我在网上找不到关于这个回调错误的太多帮助。
我的代码如下。
$ch = curl_init();
curl_setopt($ch, CURLOPT_VERBOSE, TRUE);
curl_setopt($ch, CURLOPT_URL, 'sftp://user:@12.12.12.12:22/testfile.gz');
curl_setopt($ch, CURLOPT_PROTOCOLS, CURLPROTO_SFTP);
curl_setopt($ch, CURLOPT_SSH_PUBLIC_KEYFILE,'C:\keys\public.pub');
curl_setopt($ch, CURLOPT_SSH_PRIVATE_KEYFILE,'C:\keys\private.ppk');
curl_setopt($ch, CURLOPT_SSH_HOST_PUBLIC_KEY_MD5,'2acfe24108c37a276a93ac3398a5oe8f');
curl_setopt($ch, CURLOPT_SSH_AUTH_TYPES,CURLSSH_AUTH_PUBLICKEY);
curl_setopt($ch, CURLOPT_UPLOAD, 1);
$fp = fopen($localfile, 'r');
curl_setopt($ch, CURLOPT_INFILE, $fp);
curl_setopt($ch, CURLOPT_INFILESIZE, filesize($localfile));
$sR = curl_exec ($ch);
这是运行测试的输出
