【AngularJS】Upload image

This time we use the ng-file-upload control to implement the upload function

1 Download tool
bower install ng-file-upload
bower install ng-file-upload-shim (for non html5 suppport supports non-html5 browsers)

2 Write a page

<div class="input-group">
 <input class="form-control" ng-model="formModel.picture" type="text" style="width: 500px;">
        <div class="btn btn-default" ngf-select="upload($file)" ngf-pattern="'image/*'" ngf-multiple="false" ng-model="file" name="file">选择文件</div>
           <div style="height:80px">
                <img style="height:100%;" ng-src="{{formModel.picture}}">
             </div>
   </div>

3 angular controller

controllers.controller('xxx', function ($scope, $window, $http) {
  $scope.file={};
  $scope.upload = function () {
        if (!$scope.file) return;

            $scope.isLoadding = true;

            var formData = new FormData();
            formData.append("file", $scope.file);

            $http.post('xxx/image', formData, {
                transformRequest: function (data, headersGetterFunction) {
                    return data;
                },
                headers: {'Content-Type': undefined}
            }).success(function (resultJson, status) {
                //check data
                if (resultJson.success) {
                    $scope.formModel.picture = resultJson.data;
                } else {
                    $scope.tipAlert(resultJson.errorMsg);
                }
            });
    };
});

4 Spring backend

@ResponseBody
    @RequestMapping("/image")
    public Result<String> imageUpload(@RequestParam(value = "file", required = true) MultipartFile imgFile) {

        String picUrl="";
        String regex = ".*\\.(jpg|png|bmp|gif)";
        if (Pattern.matches(regex, imgFile.getOriginalFilename()) && imgFile.getSize() <= 2 * 1024 * 1024) {
            File img = new File("ba_" + convert(imgFile.getOriginalFilename()));
            //...
        }

        return Result.wrapSuccess(picUrl);
    }
