这是字符串类型.然后我提取了附件的zip文件数据，即
This is of type string. and i extracted the attached zip file data i.e.

这表明其中包含report.xml.因此，当我将这些数据写入zip文件时，它会创建一个zip文件，并且在提取时会出现错误.
This shows that it has a report.xml in it. So when i write this data in a zip file, it creates a zip file and upon extract gives error.
fs.writeFile("./static/DownloadFile.zip", fileData, 'binary', function(err){
if (err) throw err;
console.log("success");
});
我该如何正确地将这些数据写入zip文件中.请咨询.如果需要更多信息.
How can i write this data in a zip file properly. Pls advice. If required any more information.
我尝试用PHP编写zip文件，并使用以下代码成功编写了该文件:
I tried writing the zip file in PHP and is succssfully writing it with this code:
$zipFilename="DownloadFile.zip";
$data = $fileData;
$handler = fopen($zipFilename, 'wb')
or die("Failed. Cannot Open $zipFilename to Write!</b></p>");
fwrite($handler, $data);
fclose($handler);
请告知我如何在Node.js中实现相同的目标.
Please advice how can i achieve the same thing in nodejs.
推荐答案
正如我在您的代码示例中看到的那样，您的二进制数据已被请求模块处理.只需在请求设置中使用
As I see in your code example your binary data is already mangled by request module. Just use in request setting
encoding:null
，并且zip文件是有效的二进制文件(现在是缓冲区，而不是utf-8字符串！)，您可以进行解压缩.只要您看到问题标记，您仍然会遇到编码问题.
and the zip file is a valid binary in body (now buffer instead of utf-8 string!) you can decompress. As long as you see the questions marks you still have the encoding issue.
