當kendo上傳成功時k-file-error

我設法使用Kendo和AngularJS上傳文件，但是我的文件保持紅色並且有k-file-error類，文件已上傳，我可以將它們放在後面。爲什麼會有錯誤？你可以幫我嗎？當kendo上傳成功時k-file-error

<div class="demo-section k-content"> 
     <div> 
      <h4>Upload files</h4> 
      <div class="dropZoneElement">Drag and drop file here</div> 
      <input name="files" 
       ng-model="vm.files" 
       type="file" 
       kendo-upload 
       k-async="{ saveUrl: 'http://localhost:5000/api/upload/', removeUrl: 'remove', autoUpload: true, withCredentials: false }" 
       k-select="onSelect" 
       k-upload="onUpload" 
       k-progress="onProgress" 
       k-success="onSuccess" 
       options="vm.options" 
       /> 
     </div> 
     <button ng-click="vm.test()">Test</button> 
    </div> 

class DocumentController { 
    /* @ngInject */ 
    constructor($scope, authTokenService) { 
    this.name = 'document'; 
    $scope.onSelect = e => { 
     // console.log(e.files); 
    }; 
    $scope.onUpload = e => { 
     const token = authTokenService.getToken(); 
     // Check if the token is expire 
     if (token && authTokenService.isExpired(token)) { 
     authTokenService.setToken(); 
     } 
     const xhr = e.XMLHttpRequest; 
     if (xhr) { 
     xhr.addEventListener('readystatechange',() => { 
      if (xhr.readyState === 1) { 
      // Add the token to the header 
      if (token) { 
       xhr.setRequestHeader('Authorization', `Bearer ${token}`); 
      } 
      } 
     }); 
     } 
    }; 
    $scope.onSuccess = e => { 
     console.log(e); 
    }; 
    $scope.onProgress = e => { 
     // console.log(e); 
    }; 
    this.options = { 
     dropZone: '.dropZoneElement' 
    }; 
    } 
} 

export default DocumentController;

你的服務器動作（http：// localhost：5000/api/upload）返回什麼？所有的上傳演示都有這個：「//返回一個空字符串表示成功」。 –

您應該從服務器響應返回有效的JSON結果。即使return json(true)應該工作。
