我開始使用AngularJS和typescript,我試圖做一個與WebAPI上的頁面進行通信的表單上傳。 但是我仍然無法理解語法的角度以及指令和控制器。上傳到AngularJS + Typescript的WebApi
我看到很多使用AngularJS和純JavaScript的例子,但是不能將javascript代碼轉換爲typescript。我正在使用ng-file-upload庫。我是一個小白:(
HTML:
<html>
<body>
<form action="#" method="post" ng-submit="vm.send($event)" class="">
<p>
<label>Name</label>
<input type="text"
name="Name"
required="required"
ng-model="vm.Name"/>
</p>
<p>
<label>Image:</label>
<input type="file"
ngf-select name="file"
accept="image/*" ngf-max-size="2MB"
ng-model="vm.Image"/>
</p>
<p ng-show="vm.Image">
<label>Preview:</label>
<img ngf-thumbnail="vm.Image" class="thumb"><button ng-click="vm.Image = null" ng-show="vm.Image">Remove</button>
</p>
<p>
<button type="reset" ng-click="vm.quit()">Quit</button>
<button>Send</button>
</p>
</form>
</body>
</html>
打字稿:
module MyFramework.Controllers.upload {
export class UploadController {
public vm: any;
public window: any;
public static $inject = ["framework", "$http", "$scope", "Upload", "$timeout"];
constructor(framework, private $http, private $scope, private $Upload, private $timeout) {}
send(event) {
event.preventDefault();
this.$http.post("api/upload", this.vm)
.success((message) => {
alert("Ok");;
})
.error((message) => {
alert("Error: " + message);
});
this.$scope.uploadPic = function (file) {
file.upload = Upload.upload({
url: 'api/upload',
data: { name: this.vm.Name, image: this.vm.Image }
});
file.upload.then(function (response) {
this.$timeout(function() {
file.result = response.data;
});
},
function (response) {
if (response.status > 0)
this.$scope.errorMsg = response.status + ': ' + response.data;
});
});
}
quit() {
//quit window funtion
}
}
}
我在CS#-WebApi功能接收文件:
[HttpPost]
public string Post(string Name, Byte[] Image)
{
//save the file in database
}
我想試圖使角度文件到達WebAPI控制器,並將其視爲Byte [],但我不能。我在做什麼錯了?謝謝大家。
