使用NodeJ将文件上传到Google云端硬盘时，如何获取进度状态? [英] How to get progress status while uploading files to Google Drive using NodeJs?

问题描述

我正在尝试使用nodeJs将文件上传到Google云端硬盘时获取进度状态值.

Im trying to get progress status values while uploading files to google Drive using nodeJs.

controller.js

controller.js

exports.post = (req, res) => {
//file content is stored in req as a stream 
// 1qP5tGUFibPNaOxPpMbCQNbVzrDdAgBD is the folder ID (in google drive) 
  googleDrive.makeFile("file.txt","1qP5tGUFibPNaOxPpMbCQNbVzrDdAgBD",req);

};

googleDrive.js

googleDrive.js

...
    makeFile: function (fileName, root,req) {

        var fileMetadata = {
            'name': fileName,
            'mimeType': 'text/plain',
            'parents': [root]
        };

        var media = {
            mimeType: 'text/plain',
            body: req
        };

        var r = drive.files.create({
            auth: jwToken,
            resource: fileMetadata,
            media: media,
            fields: 'id'
        }, function (err, file) {
            if (err) {
                // Handle error
                console.error(err);
            } else {
                // r => undefined
                console.log("Uploaded: " + r);
            }
        });


    },
...

推荐答案

此修改如何?

• 它使用了onUploadProgress.

makeFile: function (fileName, root,req) {
    var fileMetadata = {
        'name': fileName,
        'mimeType': 'text/plain',
        'parents': [root]
    };

    var media = {
        mimeType: 'text/plain',
        body: req
    };

    var r = drive.files.create({
        auth: jwToken,
        resource: fileMetadata,
        media: media,
        fields: 'id'
    }, {
      onUploadProgress: function(e) {
        process.stdout.clearLine();
        process.stdout.cursorTo(0);
        process.stdout.write(e.bytesRead.toString());
      },
    }, function (err, file) {
        if (err) {
            // Handle error
            console.error(err);
        } else {
            console.log("Uploaded: " + file.data.id);
        }
    });
},

注意:

• 如果要将进度显示为％"，请使用文件大小.
• 已确认此脚本可在googleapis@33.0.0上使用.

Note:

• If you want to show the progression as "%", please use the file size.
• It was confirmed that this script worked at googleapis@33.0.0.
• axios
• Google/google测试-api-nodejs-client
• axios
• test of google/google-api-nodejs-client

在我的环境中，我正在使用上面的脚本.但是，如果这在您的环境中不起作用，并且我误解了您的问题，对不起.

In my environment, I'm using the script like above. But if this didn't work in your environment and if I misunderstand your question, I'm sorry.
