我编写了API并在更改后将数据推送到Heroku中时将其上传到Heroku服务器中,然后所有图像都消失了。我不知道为什么他们没有出现。我找到了其他一些选项,例如直接在Google驱动器中上传图片,我们可以在那里获取,但是我已经浏览了所有文档。我还没有做到谷歌驱动器的图像 谁能帮助我提出任何推荐或建议等? 谢谢副词

如果您想使用npm软件包将图像上传到Google云端硬盘,则可以尝试以下方法:
yarn add googleapis
authorize
和uploadFile
。 credentials.json
文件中读取您的凭据,调用authorize
并调用uploadFile
作为回调。上传图片的代码:
const fs = require('fs');
const { google } = require('googleapis');
// If modifying these scopes, delete token.json.
const SCOPES = ['https://www.googleapis.com/auth/drive.metadata.readonly'];
const TOKEN_PATH = 'token.json';
/**
* Create an OAuth2 client with the given credentials, and then execute the given callback function.
*/
function authorize(credentials, callback) {
const {client_secret, client_id, redirect_uris} = credentials.installed;
const oAuth2Client = new google.auth.OAuth2(
client_id, client_secret, redirect_uris[0]);
// Check if we have previously stored a token.
fs.readFile(TOKEN_PATH, (err, token) => {
if (err) return getAccessToken(oAuth2Client, callback);
oAuth2Client.setCredentials(JSON.parse(token));
callback(oAuth2Client);
});
}
/**
* Describe with given media and metaData and upload it using google.drive.create method()
*/
function uploadFile(auth) {
const drive = google.drive({version: 'v3', auth});
const fileMetadata = {
'name': 'photo.jpg'
};
const media = {
mimeType: 'image/jpeg',
body: fs.createReadStream('files/photo.jpg')
};
drive.files.create({
resource: fileMetadata,
media: media,
fields: 'id'
}, (err, file) => {
if (err) {
// Handle error
console.error(err);
} else {
console.log('File Id: ', file.id);
}
});
}
fs.readFile('credentials.json', (err, content) => {
if (err) return console.log('Error loading client secret file:', err);
// Authorize a client with credentials, then call the Google Drive API.
authorize(JSON.parse(content), uploadFile);
});
还要检查官方文档:Node.js quickstart,Uploading files
答案 1 :(得分:-1)
@KarlR的回答很有帮助,但是代码本身有错误。 (该范围不支持文件上传)。让我逐步说明这一点,以便您可以轻松地将文件上传到Google云端硬盘。
步骤1:转到Google Drive API V3 NodeJS快速入门
按照初始步骤进行操作,看看它是否有效。然后继续下一步。
步骤2:具有一个名为uploadFile
的函数,并更改范围以适合上载。代码段如下所示。
在下面的示例中,该文件是从files/photo.jpg
获取的,并被重命名为photo.jpg
并上传到Google云端硬盘的root
文件夹中。
const fs = require('fs');
const { google } = require('googleapis');
// If modifying these scopes, delete token.json.
const SCOPES = ['https://www.googleapis.com/auth/drive.file'];
const TOKEN_PATH = 'token.json';
/**
* Create an OAuth2 client with the given credentials, and then execute the given callback function.
*/
function authorize(credentials, callback) {
const {client_secret, client_id, redirect_uris} = credentials.installed;
const oAuth2Client = new google.auth.OAuth2(
client_id, client_secret, redirect_uris[0]);
// Check if we have previously stored a token.
fs.readFile(TOKEN_PATH, (err, token) => {
if (err) return getAccessToken(oAuth2Client, callback);
oAuth2Client.setCredentials(JSON.parse(token));
callback(oAuth2Client);
});
}
/**
* Get and store new token after prompting for user authorization, and then
* execute the given callback with the authorized OAuth2 client.
* @param {google.auth.OAuth2} oAuth2Client The OAuth2 client to get token for.
* @param {getEventsCallback} callback The callback for the authorized client.
*/
function getAccessToken(oAuth2Client, callback) {
const authUrl = oAuth2Client.generateAuthUrl({
access_type: 'offline',
scope: SCOPES,
});
console.log('Authorize this app by visiting this url:', authUrl);
const rl = readline.createInterface({
input: process.stdin,
output: process.stdout,
});
rl.question('Enter the code from that page here: ', (code) => {
rl.close();
oAuth2Client.getToken(code, (err, token) => {
if (err) return console.error('Error retrieving access token', err);
oAuth2Client.setCredentials(token);
// Store the token to disk for later program executions
fs.writeFile(TOKEN_PATH, JSON.stringify(token), (err) => {
if (err) return console.error(err);
console.log('Token stored to', TOKEN_PATH);
});
callback(oAuth2Client);
});
});
}
/**
* Describe with given media and metaData and upload it using google.drive.create method()
*/
function uploadFile(auth) {
const drive = google.drive({version: 'v3', auth});
const fileMetadata = {
'name': 'photo.jpg'
};
const media = {
mimeType: 'image/jpeg',
body: fs.createReadStream('files/photo.jpg')
};
drive.files.create({
resource: fileMetadata,
media: media,
fields: 'id'
}, (err, file) => {
if (err) {
// Handle error
console.error(err);
} else {
console.log('File Id: ', file.id);
}
});
}
fs.readFile('credentials.json', (err, content) => {
if (err) return console.log('Error loading client secret file:', err);
// Authorize a client with credentials, then call the Google Drive API.
authorize(JSON.parse(content), uploadFile);
});
第3步:更改要上传的文件的名称
在uploadFile
功能中,更改name
属性。
const fileMetadata = {
'name': 'any_name_you_like'
};
第4步:上传不同的文件类型
您只需要在uploadFile
函数中更改以下代码段。有关首选的文件扩展名,请参见mostly used mime types。
const media = {
mimeType: 'any_mime_type',
body: fs.createReadStream('files/photo.jpg')
};
第5步:将文件上传到Google云端硬盘上的特定文件夹
打开浏览器并登录到您的Google云端硬盘。转到特定文件夹,然后查看浏览器URL。如下图所示。
https://drive.google.com/drive/u/0/folders/1xxxXj_sdsdsdsd0Rw6qDf0jLukG6eEUl
1xxxXj_sdsdsdsd0Rw6qDf0jLukG6eEUl 是文件夹ID(父ID)。在uploadFile
函数中更改以下代码段。
const fileMetadata = {
'name': 'any_file_name',
parents: ['1xxxXj_sdsdsdsd0Rw6qDf0jLukG6eEUl']
};
希望这足以满足您的要求。
