我是Angular / Node的新手,似乎无法找出我遇到的问题。
我正在尝试使用client-ftp连接到ftp,并且在实现方面遇到麻烦。本质上,我是在前端创建这样的按钮:
<button class="btn btn-primary" (click)="downloadFile()"><i class="fa fa-file-photo-o"></i> Download Screenshot</button>
并尝试通过这样的click事件来实现它:
downloadFile(){
console.log('Connecting to sftp...');
var ftpClient = require('ftp-client'),
config = {
host: 'localhost',
port: 22,
user: 'anonymous',
password: 'anonymous'
},
options = {
logging: 'basic'
},
client = new ftpClient(config, options);
console.log('Downloading Screenshot...');
client.connect(function () {
client.download('/sftFilepPath', './Downloads', {
overwrite: 'none'
}, function (result) {
console.log(result);
});
});
}
我一直遇到错误,但是每次按下按钮时都说:TypeError: Socket is not a constructor
。我要在调试器中同时显示两个console.log()调用,所以我认为这与我尝试实际连接和下载的位置有关。
我尝试为FtpClient命名空间调用import并在构造函数中创建一个私有客户端参数并加以解决,但这似乎也不起作用。
我知道new关键字会隐式调用一个构造函数,但是我在代码的任何地方都没有引用“ Socket”。也许我想念什么?
这是我的导入和构造函数供参考:
import { Component, ElementRef, Input, OnInit, OnDestroy } from '@angular/core';
import { TestInstance, Test, TestDetails } from '../../objModules/index';
import { RunServices } from './run.services';
import { Observable } from 'rxjs/Rx';
import * as $ from 'jquery';
import * as _ from 'underscore';
import { ModalController } from './run.modal.controller';
// import { FtpClient } from 'ftp-client';
@Component({
templateUrl: './run.modal.component.html',
moduleId: module.id.toString(),
selector: 'app-test-data',
providers: [ RunServices ]
})
export class ModalComponent implements OnInit, OnDestroy {
testInstance: TestDetails;
id: string;
private element: JQuery;
private runId: string;
private test$: Observable<Test>;
private testHistory$: Observable<TestInstance[]>;
private test: Test;
private testHistory: TestInstance[];
private selectedTest: TestInstance;
private latestRuns: TestInstance[];
private averagePass: number;
private averageFail: number;
services: RunServices;
constructor(private modalController: ModalController, private el: ElementRef, private runServices: RunServices) {
this.element = $(el.nativeElement);
this.services = runServices;
// Initialize these objects so we don't get any errors
this.test = new Test(' ', ' ', ' ', [' '], ' ', ' ');
this.testHistory = new Array<TestInstance>(new TestInstance(' ', ' ', ' ', 0, ' ', ' ', ' ', ' ', ' '));
this.testInstance = new TestDetails(' ', ' ', ' ', ' ', ' ', ' ', ' ', 0, null, ' ');
this.selectedTest = new TestInstance(' ', ' ', ' ', 0, ' ', ' ', ' ', ' ', ' ');
}

我的猜测是您的ftp客户端太旧了。系统环境变化越来越快。但是,此客户端自2015年以来就没有进行过更新。请尝试使用最新的客户端,例如jsftp

初始概述
client.download
方法中您的文件路径存在异常。路径/stfFilepPath
似乎有一个额外的'p'。除非它是路径的实际名称,否则请尝试将其删除。
所以;
client.download('/sftFilepPath', './Downloads'
成为
client.download('/sftFilePath', './Downloads'
尝试一下,让我知道它是否有效。如果没有,请尝试Lynx的解决方案。
