使用PHP将文件上传到Google Cloud Storage Bucket

Question

I've searched a lot (and even found some helpful links like this one Upload a file to Google Cloud Storage Bucket with PHP and Ajax ) but I couldn't get it working. 我搜索了很多（甚至找到了一些有用的链接，比如这个用PHP和Ajax将文件上传到谷歌云存储桶），但我无法让它工作。 I need to upload a txt file to my google cloud storage bucket. 我需要将txt文件上传到我的Google云存储分区。

Here's my code: 这是我的代码：

gcp_storage.php: gcp_storage.php：

<?php

if(isset($_FILES['file'])){
    $errors= array();
    // Authentication with Google Cloud Platform
    $client = new StorageClient(['keyFilePath' => 'cloudtest-2412**-a66e94ba56**.json']);
    $bucket = $client->bucket('cloudtest-2412**.appspot.com ');

    // Upload a file to the bucket.
    $file = pathinfo($_FILES['file']['name']);
    $prefix = uniqid('prefix_', true); //generate random string to avoid name conflicts
    $filename = $prefix . "." . $file['extension'];

    $bucket->upload(
      fopen($_FILES['file']['tmp_name'], 'r'),
      ['name' => $filename]
    );  
}

?>

html and js: html和js：

<html>
<form id="fileForm" action="" method="post" enctype="multipart/form-data">
    <div class="form-row">
        <br/>
        <div class="form-group">
            <label for="textFile">Text File: </label>
            <br/>
            <input type="file" name="file" id="textFile">
        </div>
    </div>
    <br>
    <button type="submit" class="btn btn-lg btn-primary"> Upload </button>
</form>

</html>

<script
  src="https://code.jquery.com/jquery-3.4.1.min.js"
  integrity="sha256-CSXorXvZcTkaix6Yvo6HppcZGetbYMGWSFlBw8HfCJo="
  crossorigin="anonymous"></script>

<script>

    $(document).on('submit', '#fileForm', function (e) {
    e.preventDefault();
    var data = new FormData($('#fileForm').get(0));
    $.ajax({
        type: 'POST',
        url: 'gcp_storage.php',
        data: data,
        processData: false,
        contentType: false,
        success: function ($data) {
            console.log('Succcess');
            $('#success').attr('hidden', false);
        }
    });
});

</script>

*It shows on my console success but when I go to my bucket on google cloud, nothing appears... *它显示在我的控制台上成功但是当我在谷歌云上找到我的桶时，什么都没有出现......

*I downloaded the .json file from the IAM page (the file is in the same directory as the other filse) *我从IAM页面下载了.json文件（该文件与其他文件位于同一目录中）

Don't know if this really helps, if I remove the use Google\\Cloud\\Storage\\StorageClient , PHP throws me the error Class 'StorageClient' not found in /base/data/home/apps/i (when I put back the use code it just throws the 500 error, see below) 不知道这是否真的有帮助，如果我删除use Google\\Cloud\\Storage\\StorageClient ，PHP会抛出错误Class 'StorageClient' not found in /base/data/home/apps/i （当我放回使用代码它只会抛出500错误，见下文）

I've been changing the code and putting breakpoints to see if I find where the 500 error is coming from. 我一直在改变代码并设置断点，看看我是否找到了500错误的来源。 If I remove everything from my PHP file and just put echo "Test" , it works fine. 如果我从我的PHP文件中删除所有内容并将echo "Test" ，它可以正常工作。

After putting some breakpoints at the original code, I found out that the 500 error comes from this lines of code: 在原始代码上放置一些断点后，我发现500错误来自这行代码：

$client = new StorageClient(['keyFilePath' => 'cloudtest-2412**-a66e94ba56**.json']);
$bucket = $client->bucket('cloudtest-2412**.appspot.com');

(The authentication code) （验证码）

Any suggestions? 有什么建议么？

Thanks 谢谢

I think, we can see a permission error. 我想，我们可以看到权限错误。 In most cases, an internal 500 server error is due to incorrect permission in one or more files or folders. 在大多数情况下，内部500服务器错误是由于一个或多个文件或文件夹中的错误权限造成的。
