北慕城南 提交于 2020-01-05 08:23:09
问题 Is there a way to close a pop up window after the page writes binary data (PDF) to the browswer? Here are the details: Whenever my web appilcation needs to print, it will pass some parameters over to a pop up window, which will display the print options.

1、接上一篇,在webui页面,点击右侧【Create】按钮,创建爬虫任务 2、输入【Project Name】,【Start Urls】为爬取的起始地址,可以先不输入,点击【Create】进入: 3、进入爬取操作的页面 整个页面分为两栏,左边是爬取页面预览区域,右边是代码编写区域。下面对区块进行说明: 左侧绿色区域:这个请求对应的 JSON 变量,在 PySpider 中,其实每个请求都有与之对应的 JSON 变量,包括回调函数,方法名,请求链接,请求数据等等。   绿色区域右上角Run:点击右上角的 run 按钮,就会执行这个请求,可以在左边的白色区域出现请求的结果。   左侧 enable css selector helper: 抓取页面之后,点击此按钮,可以方便地获取页面中某个元素的 CSS 选择器。   左侧 web: 即抓取的页面的实时预览图。   左侧 html: 抓取页面的 HTML 代码。   左侧 follows: 如果当前抓取方法中又新建了爬取请求,那么接下来的请求就会出现在 follows 里。   左侧 messages: 爬取过程中输出的一些信息。   右侧代码区域: 你可以在右侧区域书写代码,并点击右上角的 Save 按钮保存。   右侧 WebDAV Mode: 打开调试模式,左侧最大化,便于观察调试。 4、代码编辑区 1 #!/usr/bin

How to map http response to client model type in Angular

依然范特西╮ 提交于 2020-01-05 03:48:19
问题 I have model MyObejct like this in client: class MyObject{ id: number; name: string; active: boolean; } And the http response json data like this: [ { id: "1", name: "object1", active: "true", } ] The http response is key-value pair, and all the value type is string. So how can I map the http response to 'MyObject' type. The http get function is like this: getMyObejct(name: string): Observable<MyObject> { const url = this.url + 'name/' + name; return this.http.get<MyObject>(url); // This is

python、scrapy下编写妹子图爬虫程序

烂漫一生 提交于 2020-01-05 03:41:59
软件、框架的安装主要参考:http://www.jianshu.com/p/a03aab073a35 Scrapy官方文档:https://docs.scrapy.org/en/latest/intro/install.html(安装、爬虫都有参考的) 程序逻辑、流程主要参考http://cuiqingcai.com/4421.html, 其他细节百度 环境: macOS10.12.3 Python2.7 Scrapy1.3.3 一、软件(python)、框架(scrapy)的安装 mac自带Python,根据Scrapy官网建议,最好下载最新的Python版本安装 1、安装pip工具包的支撑环境 各个电脑的情况不一样,支撑包的情况也不一样,反正一句话:缺什么就装什么,我采用 Homebrew 2、pip源修改(镜像地址) 这个一定要做,默认地址访问速度特别慢,翻墙了都很慢,最后我的总结是:有一半的时间都是因为这个原因导致的 首先创建配置文件,默认情况下Mac端好像是没有pip的配置文件的,我们需要自行创建。 打开终端,在HOME下创建.pip目录: echo $HOME mkdir .pip 接下来创建配置文件pip.conf: touch pip.conf 接下来编辑配置文件,随便使用什么编辑器打开刚刚新建的pip.conf文件,输入以下两行: [global] index
