如何使用PrimeNg將圖像從angular2上傳到php服務器？

Question

我的app.component.ts代碼

import { Http, Response } from '@angular/http';
//import the do function to be used with the http library.
import "rxjs/add/operator/do";
import {FileUploadModule} from 'primeng/primeng';
//import the map function to be used with the http library
import "rxjs/add/operator/map";
import {AccordionModule} from 'primeng/primeng';      
import {MenuItem} from 'primeng/primeng';            //api
@Component({
  selector: 'my-app',
  template:  '<p-fileUpload name="myfile[]" url="./upload.php"> </p-fileUpload>'  ,
})
export class AppComponent   {
 name = 'Angular';
}

我的app.module.ts代碼

 import { NgModule } from '@angular/core'; import { BrowserModule } from '@angular/platform-browser'; import { HttpModule } from '@angular/http' import { AppComponent } from './app.component'; import { FormSubmitionComponent } from "./components/form.component"; import {FormsModule} from "@angular/forms" import {AccordionModule} from 'primeng/primeng'; import {MenuItem,FileUploadModule} from 'primeng/primeng'; @NgModule({<br> imports: [ BrowserModule,FormsModule ,HttpModule,FileUploadModule], declarations: [ AppComponent ,FormSubmitionComponent], bootstrap: [ AppComponent ] }) export class AppModule { }

我運行它時來自https://www.primefaces.org/primeng/#/fileupload的代碼顯示

您還需要更新模塊：

import {FileUploadModule} from 'primeng/primeng';

@Module({
    // ...
    imports: [FileUploadModule]
})
