响应中的 csv 数据在哪里？

Question

我正在使用 fetch 来获得 CSV 具有以下内容：

const csv = await fetch('https://www.mysite-com/admin/order?_export_=page%3A1', {credentials: 'include'});

这是 `csv' 的打印输出：

CSV is:  Response {
  size: 0,
  timeout: 0,
  [Symbol(Body internals)]:
   { body:
      Gunzip {
        _readableState: [ReadableState],
        readable: true,
        _events: [Object],
        _eventsCount: 7,
        _maxListeners: undefined,
        _writableState: [WritableState],
        writable: false,
        allowHalfOpen: true,
        _transformState: [Object],
        bytesWritten: 0,
        _handle: [Zlib],
        _hadError: false,
        _writeState: [Uint32Array],
        _outBuffer:
         <Buffer 3c 21 44 4f 43 54 59 50 45 20 68 74 6d 6c 3e 0a 3c 68 74 6d 6c 3e 0a 3c 68 65 61 64 3e 0a 20 20 3c 6d 65 74 61 20 63 68 61 72 73 65 74 3d 22 75 74 66 ... >,
        _outOffset: 0,
        _level: -1,
        _strategy: 0,
        _chunkSize: 16384,
        _defaultFlushFlag: 2,
        _finishFlushFlag: 2,
        _nextFlush: -1,
        _info: undefined },
     disturbed: false,
     error: null },
  [Symbol(Response internals)]:
   { url: 'https://www.mysite-com/admin/auth/login',
     status: 200,
     statusText: 'OK',
     headers: Headers { [Symbol(map)]: [Object] } } }

16384 的 chunkSize 似乎与我正在下载的文件大小相符。但是如何从 csv 中检索数据呢？已尝试 csv.text()，但出现错误。

更新：

尝试了以下方法：

const csv = fetch('https://www.mysite-com/admin/order?_export_=page%3A1', {credentials: 'include'})
                             .then(r => r.text)
                             .catch(err => {
                              console.log("Error downloading order csv.", err);
                             });
if (csv) {
       fs.writeFile('./tmp/order/order.xls', csv, 'utf8', err => {
        console.log("Error saving downloaded order csv.", err);
      });

返回Error saving downloaded order csv null

Answer 1

fetch returns 对 Response 的承诺。根据该响应，您应该能够调用 await response.text() 来获取字符串。

Answer 2

const csv = fetch('https://www.mysite-com/admin/order?_export_=page%3A1', {
    credentials: 'include'
  })
  .then(function(response) {
    return response.text;
  })
  .then(function(resText) {
    console.log(resText);
  });

响应中的 csv 数据在哪里？

Where is the csv data in response?
