Google Drive API V3 Javascript - 创建包含内容的文件

问题描述

之前有人问过这个问题，但答案是使用 API V2.谷歌文档没有说明如何使用 javascript 客户端代码创建包含其内容的文件.我尝试使用节点下列出的代码，但是，它只创建文件，不插入任何内容.这是我的代码:

This question has been asked before, but the answer was using API V2. The google documentation does not clarify how to create a file with its content using javascript client code. I tried using the code listed under Node, however, it only creates the file, it does not insert any content. Here is my code:

  let fileMetadata = {
    'name': name,
    parents: [parentId]
  };

  let media = {
    mimeType: 'text/plain',
    body: 'content inside file'
  };

  gapi.client.drive.files.create({
    resource: fileMetadata,
    media,
    fields: 'id'
  })
  .then(response => {
    console.log('response: ', response);
  })
  .catch(() => {
    console.log('something is wrong');
  });

有人可以帮我将内容插入文件吗?

Can someone help me insert content into files please?

推荐答案

这个示例脚本怎么样?在我的环境中，虽然 gapi.client.drive.files.create() 可以在 Google Drive 上创建一个空文件，但它不能直接上传包含内容的文件.我认为这可能无法使用 multipart/related 上传文件和元数据，尽管这可能会在未来的更新中得到解决.所以现在，作为一种解决方法，我使用 XMLHttpRequest.

How about this sample script? In my environment, although gapi.client.drive.files.create() can create an empty file on Google Drive, it cannot directly upload files including contents. I think that this might not be able to upload files and metadata with the multipart/related, although this might be resolved by the future update. So now, as one of workarounds, I use XMLHttpRequest.

在使用此示例脚本之前，请确认以下几点.

Before you use this sample script, please confirm the following points.

• 在您的情况下，您已经能够使用 gapi 创建文件.在我的脚本中，访问令牌是使用 gapi 检索的.
• 使用此脚本时，请设置文件内容和元数据.

在此示例脚本中，在文件夹下创建了一个包含内容的文本文件.

In this sample script, a text file including contents is created under a folder.

var fileContent = 'sample text'; // As a sample, upload a text file.
var file = new Blob([fileContent], {type: 'text/plain'});
var metadata = {
    'name': 'sampleName', // Filename at Google Drive
    'mimeType': 'text/plain', // mimeType at Google Drive
    'parents': ['### folder ID ###'], // Folder ID at Google Drive
};

var accessToken = gapi.auth.getToken().access_token; // Here gapi is used for retrieving the access token.
var form = new FormData();
form.append('metadata', new Blob([JSON.stringify(metadata)], {type: 'application/json'}));
form.append('file', file);

var xhr = new XMLHttpRequest();
xhr.open('post', 'https://www.googleapis.com/upload/drive/v3/files?uploadType=multipart&fields=id');
xhr.setRequestHeader('Authorization', 'Bearer ' + accessToken);
xhr.responseType = 'json';
xhr.onload = () => {
    console.log(xhr.response.id); // Retrieve uploaded file ID.
};
xhr.send(form);

请求正文:

在这个脚本中，form如下.使用 Drive API 的 create 方法将其发送到 Google Drive.

Request body :

In this script, form is as follows. This is sent to Google Drive using the create method of Drive API.

------WebKitFormBoundaryxX0XmxgooMjdUECR
Content-Disposition: form-data; name="metadata"; filename="blob"
Content-Type: application/json

{"name":"sampleName","mimeType":"text/plain","parents":["#####"]}
------WebKitFormBoundaryxX0XmxgooMjdUECR
Content-Disposition: form-data; name="file"; filename="blob"
Content-Type: text/plain

sample text
------WebKitFormBoundaryxX0XmxgooMjdUECR--

在我的环境中，我确认这可以正常工作.但如果这在您的环境中不起作用，我很抱歉.

In my environment, I confirmed that this works fine. But if this didn't work in your environment, I'm sorry.
