javascript - 如何在javascript中将字节码转换为zip文件

Question

我使用以下代码将字节码转换为 zip 文件，但它不会下载响应中发送的实际 xml 和 asc 文件，而是仅下载标准 zip 内容，我不知道我哪里出错了，谁能帮我解决这个问题，

 $http({
    url:url,
    method: requestType,
    data:requestBody?requestBody:"",
    headers: {
       'Content-type': "application/json",
       "SessionID":$rootScope.token
    },
    responseType: 'arraybuffer'
}).success(function (data, status, headers, config) {
    let blob = new Blob([data], {type: "application/zip"});
    let objectUrl = URL.createObjectURL(blob);
    let link = document.createElement('a');
    link.href = objectUrl;
    link.download = fileName;
    link.click();
    window.URL.revokeObjectURL(link.href);
    $scope.exp = {}; // to reset the export form after submit.
    $scope.surveyReportdownloading = false;
    $scope.tabActive = false;
 }).error(function (error) {
    //upload failed
    console.log(error);
});

这根本不是下载实际的文件。谁能帮助我解决这个问题。后端团队发送的字节码如下。

感谢任何帮助。谢谢!

问题似乎出在 type 参数上，请尝试使用以下代码

您可以从headers访问content-type。

如果不起作用，请尝试使用application/zip、application/octet-stream

$http({
  url: url,
  method: requestType,
  data: requestBody ? requestBody : "",
  headers: {
    'Content-type': "application/json",
    "SessionID": $rootScope.token
  },
  responseType: 'arraybuffer'
}).success(function(data, status, headers, config) {
  let blob = new Blob([data], {
    type: headers['content-type']
    //               OR
    // type:"application/zip, application/octet-stream"
  });
  let objectUrl = URL.createObjectURL(blob);
  let link = document.createElement('a');
  link.href = objectUrl;
  link.download = fileName;
  link.click();
  window.URL.revokeObjectURL(link.href);
  $scope.exp = {}; // to reset the export form after submit.
  $scope.surveyReportdownloading = false;
  $scope.tabActive = false;
}).error(function(error) {
  //upload failed
  console.log(error);
});

 var blob = new Blob([response.data],{type:headers['content-type']});
  var link = document.createElement('a');
  link.href = window.URL.createObjectURL(blob);
  link.download = "Filename";
  link.click();
