ungzip 不適用於 axios 后請求

Question

我想壓縮大量字符串數據，並希望登錄到文件並下載此文件，以便將來可以在需要時使用該數據，為此我選擇了“gzip-node”。 我可以 zip 字符串並存儲到文件中，但在解壓縮時，它顯示以下錯誤

(node:71720) UnhandledPromiseRejectionWarning: Error: Error: incorrect header check
[0]     at Gunzip.cb (C:\Users\nagasudha.sanikommu\project-omega - Copy (4) - Copy\node_modules\node-gzip\dist\index.js:17:49)

節點代碼

app.post('/open',function(request,response,next){
    console.log(request);
    if(request.files.selectedFile){
        let file=request.files.selectedFile;
        let dest=__dirname+'/uploads/example.txt';
        file.mv(dest,function(err){
            if(err){
                response.send("File not found");
            }
            else{
                fs.readFile(__dirname+'/uploads/example.txt',function(err,data){
                    ungzip(data.toString()).then((u)=>{
                        response.send(u);
                    })
                })
            }
        })

    }

})

反應js代碼

handleFileOpen=function(event) {
  let data=new FormData();
  data.append('selectedFile',event.target.files[0]);
  axios({
       method:"post",
       url:"http://localhost:4001/open",
       data:data,
   })
   .then(res=>{
       console.log(res.data);
  })

您需要像這樣請求通過Header

axios.post('http://localhost:4001/open', data,
    {
        responseType: 'arraybuffer',
        headers: {
            'Content-Type': 'multipart/form-data',
        }
    })
