【问题描述】：

我正在尝试获取存储在 Firebase 存储中的 id jpeg 并将其上传到条带，以便让我的客户验证他们的身份。但是我遇到了几个错误并且函数停止了

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” 然后我的功能停止了。

【问题讨论】：

您是否从 Stripe 或您的 getidFile 函数返回错误？
根据docs：Modifying a file rather than replacing it may require a flags mode of r+ rather than the default mode w。如果您在这里遇到错误fs.createWriteStream("test.jpg");，这可能是问题的根源

【解决方案1】：

我不使用网址。使用 admin.storage() 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',
    },
  });
});
