如何正确下载 response.data?

How do i properly download the response.data?

这是方法.我在原始调用正文中发送了一些所需的信息，并发送了一个需要上传的文件，以便我可以获取需要下载的其他文件.

Here is the method. I send a few needed information in my raw call body and a file that is needed to be uploaded so i can get the other files that i need to download.

upload() {
      console.log("uploading")
      let formData = new FormData();
      let gerarMenus = "on";
      let zipName= "test";
      let var1= "on";
      let var2= "on";
      let var3= "on";
      let var4= "on";
       this.files.forEach((f,x) => {
         formData.append('file'+(x+1), f);

       });
       formData.append('zipName', zipName);
         formData.append('var1', var1);
         formData.append('var2', var2);
         formData.append('var3', var3);
         formData.append('var4', var4);

       axios
         .post("/myUrl/downloadFile", formData)
         .then((response) => {
           console.log(response.data)
            const url = window.URL.createObjectURL(new Blob([response]));
            const link = document.createElement('a');
            link.href = url;
            link.setAttribute('download', zipName+ '.zip');
            document.body.appendChild(link);
            link.click()}
            ).catch(e => {
          console.error(e);
        });

我尝试了 tony19 的回答，但我仍然遇到同样的错误.不确定它是否有帮助，但我想得到多个 xml 和 sql 文件.

I tried tony19's answer but i still get the same error. Not sure if it is any help but i am suppose to get multiple xml and sql files.

这是我的 console.log() 中的 response.data 打印件:

here's a print of response.data in my console.log():

推荐答案

尝试在您的请求中将 responseType 选项设置为 blob:

Try to set a responseType option to blob in your request:

axios
     .post("/myUrl/downloadFile", formData, {
          responseType: 'blob'
     })

并在 Blob 构造函数中使用 response.data 就像@tony19 已经提到的那样.

And use response.data in a Blob constructor as @tony19 already mentioned.
