我有一个角度应用程序,用户可以从他们的保管箱帐户中选择一个文件,然后应用程序下载该文件。这是代码。
$scope.$watchCollection('dropBoxFiles', function (newDBFiles) {
$scope.invalidResume = false;
if (newDBFiles.length > 0) {
var mimeType = $scope.validateFile(newDBFiles[newDBFiles.length - 1].name);
if (mimeType === ''){
return false;
}
var remote = new XMLHttpRequest();
remote.open('GET', newDBFiles[newDBFiles.length - 1].link);
remote.responseType = "arraybuffer";
remote.onload = function() {
$scope.filename = newDBFiles[newDBFiles.length - 1].name;
$scope.fileBlob = new Blob([remote.response], {type: mimeType});
$scope.$digest();
};
remote.send();
}
});
我正在努力尝试编写一个涵盖 xmlhttprequest 部分的测试。这是我到目前为止所拥有的,但我收到了这个错误 -
TypeError: 'undefined' is not an object (evaluating 'request.respondWith')
我知道错误的含义,但我不确定我为什么会得到它。这是测试。
describe('dropbox watch collection ', function () {
var testResponses = {
results: {
success: {
status: 200,
responseText: 'test text',
response: '<html><body>hello</body></html>'
}
}
};
beforeEach(inject(function ($rootScope, $controller) {
jasmine.Ajax.install();
scope = $rootScope.$new();
$controller('ApplyController', { $scope: scope});
}));
afterEach(function() {
jasmine.Ajax.uninstall();
});
it('sets the scope filename to selected file if using a valid file type', function () {
var selectedFile = {
name: 'test.html',
link: 'http://dropbox.com',
mimeType: 'text/html'
};
scope.dropBoxFiles.push(selectedFile);
scope.$digest();
var request = jasmine.Ajax.requests.mostRecent();
request.respondWith(testResponses.results.success);
expect(scope.filename).toBe(selectedFile.name);
expect(typeof scope.fileBlob).toBe('blob');
});
});
