我已经从使用常规的图片上传方式(当时无法正常工作)转换为使用MKNetworking来协助我完成上传过程,我之所以使用这种方式是因为我发现它能提供更好的错误响应,并有助于解决我的问题。我得到了一个NSLog响应,其中包含一个错误信息。

我可以通过一个html表单成功上传图片,因此我确定我的php.ini文件正常,并且允许我上传比我在iPhone上请求的更多的内容。

最后但并非最不重要的,我的PHP。
$mysqli = new mysqli($host, $username, $password, $database);
if ($stmt = $mysqli->prepare("UPDATE `user` SET imagepath=? WHERE email=?"))
{
$stmt->bind_param('ss', $albumname, $email);
$email = $_POST['email'];
$uploaddir = 'images/users/';
$file = basename($_FILES['userfile']['name']);
$uploadfile = $uploaddir . $file;
if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) {
}
$albumname = $uploadfile;
$stmt->execute();
$stmt->close();
}
else {
printf("Prepared Statement Error: %s\n", $mysqli->error);
}
$mysqli->close();
我在我的服务器上的PHP日志中没有发现任何错误。

并提供请求的 NSLog,curl 命令行应该有一个选项用于您的 userfile 参数。 - Cory Powers[self.flOperation addData:UIImageJPEGRepresentation(image, 0.5) forKey:@"userfile" mimeType:@"image/jpeg" fileName:@"avatar.jpg"]
