如何使用PHP从Outlook下载附件？

Question

我想下载一个附件。我已收到附文，要求：

/me/message/{message_id}/attachments/{attachment_id}

答复如下：

[_propDict:protected] => Array
        (
            [@odata.context] => https://graph.microsoft.com/v1.0/$metadata#users('username')/messages('messageId')/attachments/$entity
            [@odata.type] => #microsoft.graph.fileAttachment
            [@odata.mediaContentType] => application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
            [id] => xxx
            [lastModifiedDateTime] => 2019-11-02T17:50:52Z
            [name] => xxx.xlsx
            [contentType] => application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
            [size] => 33459
            [isInline] => 
            [contentId] => f_k2hv435z0
            [contentLocation] => 
            [contentBytes] => GuzzleHttp\Psr7\Stream Object
                (
                    [stream:GuzzleHttp\Psr7\Stream:private] => Resource id #374
                    [size:GuzzleHttp\Psr7\Stream:private] => 
                    [seekable:GuzzleHttp\Psr7\Stream:private] => 1
                    [readable:GuzzleHttp\Psr7\Stream:private] => 1
                    [writable:GuzzleHttp\Psr7\Stream:private] => 1
                    [uri:GuzzleHttp\Psr7\Stream:private] => php://temp
                    [customMetadata:GuzzleHttp\Psr7\Stream:private] => Array
                        (
                        )
                )
        )
)

这里不是sourceUrl，而是contentBytes。我能用contentBtyes做这个吗?怎么做。

Answer 1

我认为$object->getContentBytes()应该为你工作。

UPD:如果您想将内容作为文件下载，您可以执行类似的操作：

$fileName = "download.txt";
$contents =  $object->getContentBytes(); // base64_decode() here if needed

header("Content-type: text/plain"); // Or any other format
header("Content-Disposition: attachment; filename=" . $fileName);
print $contents;
die;
