Question

我正在使用此指令

myApp.directive('fileModel', ['$parse', function ($parse) {
    return {
        restrict: 'A',
        link: function(scope, element, attrs) {
            var model = $parse(attrs.fileModel);
            var modelSetter = model.assign;
            console.log(modelSetter)
            element.bind('change', function(){
                scope.$apply(function(){
                    modelSetter(scope, element[0].files[0]);
                });
            });
        }
    };
}]);

我的服务是

myApp.service('fileUpload', ['$http', function ($http) {
    this.uploadFileToUrl = function(file, uploadUrl){
        var fd = new FormData();
        fd.append('file', file);
        $http.post(uploadUrl, fd, {
            transformRequest: angular.identity,
            headers: {'Content-Type': undefined}
        })
        .success(function(){
        })
        .error(function(){
        });
    }
}]);

在我的控制器中

$scope.uploadFile = function(){
        var file = $scope.myFile;
        console.log('file is ' );
        console.dir(file);
        var uploadUrl = "/fileUpload";
        fileUpload.uploadFileToUrl(file, uploadUrl);
    };

我的问题是如何在将图片上传到我的JSfiddle URl https://jsfiddle.net/JeJenny/ZG9re/

试试这段代码，我的工作正常

this.uploadFileToUrl = function (file, uploadUrl, progressCB) {
    var fd = new FormData();
    fd.append('file', file);
    $http.post(uploadUrl, fd, {
        transformRequest: angular.identity,
        headers: { 'Content-Type': undefined },
        uploadEventHandlers: {
            progress: progressCB
        }
    })
        .success(function () {
        })
        .error(function () {
        });
}

$scope.uploadFile = function () {
    var file = $scope.myFile;
    console.log('file is ');
    console.dir(file);
    var uploadUrl = "/fileUpload";
    fileUpload.uploadFileToUrl(file, uploadUrl, , function (e) {
        if (e.lengthComputable) {
            var progressBar = (e.loaded / e.total) * 100;
            console.log(progressBar);
            //here you will get progress, you can use this to show progress
        }
    });
};

progressCB呈现的内容

我会说。使用此ng-file-upload指令。它内置了这些功能。

import sys
sys.path.append(r"C:\Users\gpathak\Documents\new scripts\Automation Scripts (Packet Range)\Document_creator")
from document creator track to train import *
