Question

的信息：

我正在使用适用于Google API的PHP客户端库
我已经在Google的开发者控制台中创建了一个项目，对于OAuth，我使用服务帐户作为应用程序类型。
我已经使用了https://developers.google.com/drive/v2/reference/files/insert#examples和https://developers.google.com/drive/v2/reference/permissions/insert#examples

我做了一个简短的示例，我使用服务帐户的凭据将文件上传到Google云端硬盘。由于服务帐户没有云端硬盘用户界面（Google Drive API Upload returns File ID/Title but document does not exist in Drive），因此我已为自己的帐户添加了权限。这很好用。但是当我在Google文档中打开文件时，我看不到上传文件的内容。以下是我的代码。在我要上传的文件中，内容是＆＃34; Hello World！＆＃34;但Google Drive上的文档中没有此信息。关于如何解决这个问题的任何想法？

        function insertFile($service, $title, $description, $parentId, $mimeType, $fileName) {
            print "<br/>Uploading file...<br/>";
            $file = new Google_Service_Drive_DriveFile();
            $file->setTitle($title);
            $file->setDescription($description);
            $file->setMimeType($mimeType);

            // Set the parent folder
            if ($parentId != null) {
                $parent = new Google_Service_Drive_ParentReference();
                $parent->setId($parentId);
                $file->setParents(array($parent));
            }

            try {
                $data = file_get_contents($fileName);

                $createdFile = $service->files->insert($file, array(
                    'data' => $data,
                    'mimeType' => $mimeType
                ));

                $newFileId = $createdFile->getId();

                // Give permission to my email so I can see the file in my Drive UI
                $myEmail = "<mygmail>";
                $userType = "user";
                $userRole = "writer";
                insertPermission($service, $newFileId, $myEmail, $userType, $userRole);

                print "<br/>File uploaded successfully!";
                downloadFile($service, $newFileId);
            } catch (Exception $e) {
                print "<br/>An error occurred: " . $e->getMessage();
            }
        }

        function insertPermission($service, $fileId, $userToPermit, $typeOfUser, $role) {
            $newPermission = new Google_Service_Drive_Permission();
            $newPermission->setValue($userToPermit);
            $newPermission->setType($typeOfUser);
            $newPermission->setRole($role);
            try {
                return $service->permissions->insert($fileId, $newPermission);
            } catch (Exception $e) {
                print "<br/>Error occurred while attempting to permit " . $userToPermit . " to file.<br/>" . $e->getMessage();
            }
            return null;
        }

        $docTitle = "UploadTest4.txt";
        $docMimeType = "text/plain";
        $docToUpload = "document.txt";
        insertFile($service, $docTitle, null, null, $docMimeType, $docToUpload);

Answer 1

之前没有找过这篇文章，但我尝试了提供的解决方案，它对我有用（对于原始海报不够奇怪）。我不得不在插入请求中添加uploadType参数。

uploadType => 'media'

file uploaded with empty content using google drive php api

上传的文件内容缺少Google云端硬盘
