我正在使用Codeigniter应用程序,并试图为用户提供上传文件的访问权限。服务器安装在运行CentOS 7和Apache 2的Google Compute Engine VM上,我试图使用Google Cloud Storage进行用户上传。目前,当我上传文件时,只有文件名被上传到GCS Bucket中,文件大小为0字节。
我的前端代码:
<body>
<form action="/includes/includes_gc/do_upload" class="dropzone" id="pfUploads" enctype="multipart/form-data">
</form>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.7/umd/popper.min.js"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/dropzone/5.5.1/min/dropzone.min.js"></script>
<script>
Dropzone.options.pfUploads = {
paramName: "file",
uploadMultiple: true,
init: function () {
this.on('complete', function (data) {
console.log(data);
});
}
};
</script>
</body>
控制器功能:
public function do_upload() {
if ($_FILES) {
$filename = $_FILES['file']['name'];
$gs_name = file_get_contents($_FILES['file']['tmp_name']);
$bucketName = 'xxxxxx.appspot.com';
$kdir = dirname(getcwd(), 2);
$storage = new StorageClient([
'keyFile' => json_decode(file_get_contents($kdir . DIRECTORY_SEPARATOR . 'xxxxxx.json'), true),
'projectId' => 'xxxxxx'
]);
$file = fopen($gs_name, 'r');
$bucket = $storage->bucket($bucketName);
$bucket->upload($file, [
'name' => $filename
]);
$test = array();
array_push($test, basename($gs_name));
array_push($test, $bucketName);
array_push($test, $filename);
echo json_encode($test);
}
}
对于解决此问题,我将不胜感激。
预先感谢。 Naveen

您正在将变量file_get_contents的返回值分配给变量gs_name
,并将该变量传递给fopen函数。
如果没有通常与该文件内容相同的路径名,请fopen
returns值false。
因此,您将值false作为第一个参数传递给$bucket->upload,这实际上会创建一个0字节的blob,其名称与您在相应存储区中提供的名称相同。
因此,底线应该起作用:
public function do_upload() {
if ($_FILES) {
$filename = $_FILES['file']['name'];
$gs_name = $_FILES['file']['tmp_name'];
$file = file_get_contents($gs_name);
$bucketName = 'xxxxxx.appspot.com';
$kdir = dirname(getcwd(), 2);
$storage = new StorageClient([
'keyFile' => json_decode(file_get_contents($kdir . DIRECTORY_SEPARATOR . 'xxxxxx.json'), true),
'projectId' => 'xxxxxx'
]);
$bucket = $storage->bucket($bucketName);
$bucket->upload($file, [
'name' => $filename
]);
}
}
还请记住,您可以使用upload
方法的返回值,例如:
$storage_object = $bucket->upload($file, ['name' => $filename]);
进一步processing。

@fhenriques ...再次感谢您的帮助和指导。我确实玩了一些,并做了一些更改。
if (!empty($_FILES)) {
foreach ($_FILES['file']['tmp_name'] as $key => $tmp_name) {
$filename = $_FILES['file']['name'][$key];
$gs_name = $_FILES['file']['tmp_name'][$key];
$file = file_get_contents($gs_name);
$bucketName = 'xxxxxx.appspot.com';
$kdir = dirname(getcwd(), 2);
$storage = new StorageClient([
'keyFile' => json_decode(file_get_contents($kdir . DIRECTORY_SEPARATOR . 'xxxxxx.json'), true),
'projectId' => 'xxxxxx'
]);
$bucket = $storage->bucket($bucketName);
$bucket->upload($file, [
'name' => $filename
]);
$storage_object = $bucket->upload($file, ['name' => $filename]);
return $storage_object;
}
}
现在,这有助于我使上传工作正常进行。非常感谢您的指导。我感谢您的帮助。
