我正在做一个项目，用户可以将文件上传到存储在AmazonS3存储桶中的网站。
不过这并没有真正奏效。。服务器看到了这个文件，一切看起来都很好，除了文件在亚马逊上结束时只有28字节大。。
这是我迄今为止的代码：
控制器
public function uploadFile()
{
$data['username'] = $this->input->cookie('username', TRUE);
$data['pagetitle'] = "Upload file";
$data['userid'] = $this->userid;
$this->load->template('uploadFile', $data);
}
public function takeUpload()
{
$config['upload_path'] = './images/screenshots/';
$config['allowed_types'] = 'gif|jpg|png';
$config['encrypt_name'] = TRUE;
$this->load->library('upload', $config);
$projectFileLoc = $_FILES['projectFile']['tmp_name'];
$projectFileName = $_FILES['projectFile']['name'];
if (!($this->upload->do_upload("previewImage")) && !($this->s3->putObject($projectFileLoc, '3dnation', $projectFileName, $this->s3->ACL_PUBLIC_READ)))
{
echo "Something went wrong...";
}
else
{
$imgData = $this->upload->data();
$previewImage = $imgData['file_name'];
//TODO: Add image to DB
}
}
视图文件（uploadFile.php）
<div class="row">
<div class="col-xs-12 col-sm-12">
<div class="jumbotron">

</div>
</div><!--/span-->

</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<button type="submit" class="btn btn-default">Upload</button>
</div>
</div>
</form>
</div>
</div>
我正在用这个S3库用最新的Codeigniter构建它
怎么了？
必须用数组调用putObject，如果要使用文件，则必须调用"putObjectFile"函数：
检查类中的定义：
public static function putObjectFile($file, $bucket, $uri, $acl = self::ACL_PRIVATE, $metaHeaders = array(), $contentType = null)
{
return self::putObject(self::inputFile($file), $bucket, $uri, $acl, $metaHeaders, $contentType);
}
原始库中的一个示例：
// Simple PUT:
if (S3::putObject(S3::inputFile($file), $bucket, $uri, S3::ACL_PRIVATE)) {
echo "File uploaded.";
} else {
echo "Failed to upload file.";
}
如您在文档中所见
