NodeJS 创建 CSV 直接写入 Google Storage

Question

我尝试了几种不同的方法来解决这个问题，但我都干了。有许多 csv 转换器，但它们似乎都写入本地文件（这在应用引擎上是不允许的）。我想将文件直接写入谷歌存储桶。

很简单……

app.get('/', (req, res) => {
  var writer = csvWriter()
  writer.pipe(fs.createWriteStream('out.csv')); // bucket.upload('out.csv);
  writer.write({hello: "world", foo: "bar", baz: "taco"})
  writer.end();
});`

Answer 1

成功了……

const blob = bucket.file('file.csv');
const blobStream = blob.createWriteStream({
  resumable: false,
});

app.get('/', (req, res) => {
  var writer = csvWriter();
  writer.pipe(blobStream);
  writer.write({hello: "world", foo: "bar", baz: "taco"})
  writer.end();
  res.end();
});
