Javascript 无法使用angularjs下载有效的zip文件，但是直接点击我的RESTAPI它就可以工作了

下面是我的angular.js代码

App.factory('JobMigrationService', ['$http','$q',function($http, $q) {

return {
    downloadSvc: function(requestPayload) {
        console.info(requestPayload);
        return $http.get('http://localhost:8080/XXXX',{params:{"params":value}},{responseType:'arraybuffer'})
        .then(
                function(response){
                    console.info(response);
                    var a = document.createElement('a');
                    var blob = new Blob([success], {'type':"application/octet-stream",'responseType':"arraybuffer"});
                    a.href = URL.createObjectURL(blob);
                    a.download = "filename.zip";
                    a.click();
                }, 
                function(errResponse){
                    console.error('Error');
                    return $q.reject(errResponse);
                }
        );
    }
}

}]);

下载正在进行中，但当尝试打开zip文件时，它表示该文件无效，但是使用RESTAPI direct hit可以正常工作

提前谢谢

我想一定是这个了

  var blob = new Blob([success], {'type':"application/octet-stream",'responseType':"arraybuffer"});

什么是[成功]？难道不是吗

   var blob = new Blob(response.data, {'type':"application/octet-stream",'responseType':"arraybuffer"});

这有点干净。我想

    App.factory('JobMigrationService', ['$http','$q',function($http, $q) {

return {
    downloadSvc: function(requestPayload) {
        console.info(requestPayload);
        return $http.get('http://localhost:8080/XXXX',{params:{"params":value}},{responseType:'blob'})
        .then(
                function(response){
                    console.info(response);
                    var a = document.createElement('a');
                    a.href = URL.createObjectURL(response.data);
                    a.download = "filename.zip";
                    a.click();
                }, 
                function(errResponse){
                    console.error('Error');
                    return $q.reject(errResponse);
                }
        );
    }
}

}]);
