角2文件上傳

Question

我新角2，我試圖用ng2-file-uploader上傳文件， 但是當我嘗試使用this example

import {Component} from '@angular/core'; 
import {UPLOAD_DIRECTIVES} from 'ng2-file-uploader/ng2-file-uploader'; 

@Component({ 
    selector: 'demo-app', 
    templateUrl: 'app/demo.html', 
    directives: [UPLOAD_DIRECTIVES], 
}) 
export class DemoApp { 
    uploadFile: any; 
    postId: number; 
    options: Object = { 
    url: 'http://localhost:10050/upload', 
    params: { 'post_id': this.postId } 
    }; 

    handleUpload(data): void { 
    if (data && data.response) { 
     data = JSON.parse(data.response); 
     this.uploadFile = data; 
    } 
    } 
} 

我得到下指令紅線：[UPLOAD_DIRECTIVES] ，

npm install ng2-file-uploader 

所以劑量任何一個有一個想法，如何在正確的方式指示？

Answer 1

更改爲：

providers: [UPLOAD_DIRECTIVES] 

好
