anjularjs的处理文件上传 前台:
<div ng-controller="UploaderController" >
input type="file" file-model="myFile" >
button ng-click="save()" >保存</button>
div>
js文件: 这里要注意的是,因为是通过anjularjs的http请求来上传文件的,所以要让当前的request成为一个Multipart/form-data请求,anjularjs对于post和get请求默认的Content-Type header 是application/json。通过设置‘Content-Type’: undefined,这样浏览器不仅帮我们把Content-Type 设置为 multipart/form-data,还填充上当前的boundary,如果你手动设置为: ‘Content-Type’: multipart/form-data,后台会抛出异常:the current request boundary parameter is null。 ps: 通过设置 transformRequest: angular.identity ,anjularjs transformRequest function 将序列化我们的formdata object.

$scope.save = function() {
var fd = new FormData();
var file = document.querySelector('input[type=file]').files[0];
fd.append('logo',file);
$http({
method:'POST',url:"your url",data: fd,headers: {'Content-Type':undefined},transformRequest: angular.identity
})
.success( function ( response ) {
alert("uplaod success");
});
}
});
ps:上面的file的获取还可以通过:var file = $scope.myFile.同时要注意在js中 data: fd,不能像普通的参数一样写为:params:{ fd,…},具体的解释是: 官方文档

params – {Object.<string|Object>} – Map of strings or objects which will be serialized with theparamSerializer and appended as GET parameters.
data – {string|Object} – Data to be sent as the request message data.
在GET方法中可以使用params ,在POST/PUT/PATCH/DELETE中不能使用params 来传递数据,要使用data来传递。
