从Firebase下载文件并上传到Stripe进行身份验证。

Question

我正在尝试从Firebase存储中获取一个ID JPEG，并将其上传到Stripe，以便允许我的客户验证他们的身份。然而，我遇到了一些错误，导致函数停止。

import * as https from 'https'
    import * as fs from 'fs'
    const stripe = Stripe('sk_test');

    function getidFile(url: string):Promise<any>{
        return new Promise((resolve,reject) => {
            const file = fs.createWriteStream("test.jpg");
            https.get(
                url,
                function(response: IncomingMessage){
                    console.log('Response ', response);
                    response.pipe(file);
                    file.on('finish', function() {
                        file.close();
                        resolve(file);
                    });
                }
            ).on('error', function(err) { // Handle errors
                reject(err);
            });
        });
    }

    function uploadFileToStripe(fileUrl:string,fileType:string,fileName:string):Promise<any>{
        return getidFile(
            fileUrl
        ).then(
            (data:any) => {
                console.log('File as blob ', data);
                const upload: Promise<any> = 
                stripe.files.create(
                    {
                        file: {
                            data: data,
                            name: fileName,
                            type: 'image/jpeg',
                        },
                        purpose: 'identity_document',
                    }
                );
                return upload.then(
                    (document: any) => {
                        console.log('Document upload ', document);
                        return document;
                    }   
                ).catch(
                    (_error: any) => {
                        console.log('Error uploading document ', _error);
                        return _error;
                    }
                )
            }
        ).catch(
            (_error:any) => {
                console.log('Error with response ', _error);
                return _error;
            }
        );
    }

错误：EROFS：只读文件系统，打开“test.jpg”，然后我的函数停止。

你是从Stripe还是从你的getidFile函数中收到错误信息的？ - Paul Asjes

根据文档： 修改文件而不是替换它可能需要一个标志模式r+，而不是默认模式w。 如果您在这里fs.createWriteStream("test.jpg");遇到错误，这可能是问题的根源。 - bhito

我不使用URL。请使用admin.storage()来访问您的文件。

export const uploadFileToStripe = functions.https.onCall(async(data,context)=>{

  const bucket = admin.storage().bucket('xyz.appspot.com');
  const path = require('path');
  const os = require('os');
  const fs = require('fs');
  const fileName = data['fileName'];
  const tempFilePath = path.join(os.tmpdir(), fileName);
  await bucket.file(fileName).download({destination:tempFilePath});

  console.log('File created at', tempFilePath);

  return await stripe.files.create({
    purpose: 'identity_document',
    file: {
      data: fs.readFileSync(tempFilePath),
      name: 'fileUploadDoc.png',
      type: 'application/octet-stream',
    },
  });
});
