Can you download images from a specific domain for each page ending in a string?

时间秒杀一切 提交于 2020-01-25 07:25:48
问题 I recently found an old website that I used to use (we'll call it example.com) which stores images on a page with the URL of your ID and a 5-character randomly-generated code. For example if my ID is HG5K , one of these images will be located at example.com/[random code here]_HG5K.png . The code generator uses a random combination of capital letters and numbers. Some examples of codes: 83JME_HG5K HD2U3_HG5K 33GIZ_HG5K What I'm asking is: if there is a way to search example.com for any pages

问题 http://127.0.0.1:8080/x?haha=1 I want to get something like ctx.QueryArgs().Get("haha") is it possible in golang's fasthttp package? 回答1: Found it ctx.QueryArgs().Peek("haha") The naming choice is unexpected. 回答2: You can retrieve a custom GET, POST PUT parameter using FormValue method: - GET (Query String such as ?user=a&pass=b); - POST, PUT body Literally, from the documentation: FormValue returns form value associated with the given key. The value is searched in the following places: Query

httpclient和htpUrlConnection用例

使用了很久框架,突然不知道,原生访问网络请求方式,回过头去看,还好,对现在流行使用okhttp也有了更深体会。 HttpURLConnection介绍: HttpURLConnection是一种多用途、轻量极的HTTP客户端,使用它来进行HTTP操作可以适用于大多数的应用程序。对于之前为何一直使用HttpClient而不使用HttpURLConnection也是有原因的。具体分析如下 HttpClient是apache的开源框架,封装了访问http的请求头,参数,内容体,响应等等,使用起来比较方便,而HttpURLConnection是java的标准类,什么都没封装,用起来太原始,不方便,比如重访问的自定义,以及一些高级功能等。 从稳定性方面来说的话,HttpClient很稳定,功能强,BUG少,容易控制细节,而之前的HttpURLConnection一直存在着版本兼容的问题,不过在后续的版本中已经相继修复掉了。 从上面可以看出之前一直使用HttClient是由于HttpURLConnection不稳定导致,那么现在谷歌虽然修复了HttpURLConnection之前存在的一些问题之后,相比HttpClient有什么优势呢?为何要废除HttpClient呢? HttpUrlConnection是Android SDK的标准实现,而HttpClient是apache的开源实现;

Scrapy基础(十三)————ItemLoader的简单使用

ItemLoader的简单使用:目的是解决在爬虫文件中代码结构杂乱,无序,可读性差的缺点 经过之前的基础,我们可以爬取一些不用登录,没有Ajax的,等等其他的简单的爬虫 回顾我们的代码,是不是有点冗长,将所需字段通过xpath或者css解析出来,再自定义语句(还不是函数中) 进行清洗;然后再装入Item中,有没有这样一种方法:从Item中可以直接清洗岂不是很简单 今天就学习 ItemLoader这样一种对戏,简单代码,可读增强 思路: 1,创建一个ItemLoad对象 2,通过该对象的add_css或者add_xpath或者add_value方法将解析语句装入ItemLoader 3,在Item.py中在Filder()中调用函数,用来清洗,处理数据 4,artical_item = item_loader.load_item() 调用这个对象的此方法,写入到Item中 具体代码: 在爬虫文件中: 1 #先引入 2 from ArticalSpider.items import JobboleArticalItem,ArticalItemLoader 3 #使用Itemloader来简化这个解析,装入Item这个过程,使得代码量减少 4 #先创建一个itemLoader()这样一个对象,不需解析list第一个等问题 5

url rewriting : How to rewrite 2 urls with same number of parameters?

问题 I've created some url rewriting rules. It works fine. But i have 2 pages with urls like that : actualites.php?id=xxx& alias=xxx --> Result : id-alias.php (ex : 1-article_name.php) equipe.php?id=xxx& alias=xxx --> Result : id-alias.php ((ex : 1-article_name.php) These 2 pages are different, not the same design, etc. I would like to rewrite these 2 different pages. My question is how to have two different rules for these 2 urls. Since they have 2 parameters, i have only one rule applied (the

一、easyexcel介绍 Java解析、生成Excel比较有名的框架有Apache poi、jxl。但他们都存在一个严重的问题就是非常的耗内存,poi有一套SAX模式的API可以一定程度的解决一些内存溢出的问题,但POI还是有一些缺陷,比如07版Excel解压缩以及解压后存储都是在内存中完成的,内存消耗依然很大。easyexcel重写了poi对07版Excel的解析,能够原本一个3M的excel用POI sax依然需要100M左右内存降低到几M,并且再大的excel不会出现内存溢出,03版依赖POI的sax模式。在上层做了模型转换的封装,让使用者更加简单方便。 easyexcel github地址 二、easyexcel使用 1、excel导出 通过注解设置字段属性 @Data public class Person { @ExcelProperty(value = {"人员信息", "姓名"}, index = 0, converter = AutoConverter.class) private String name; @ExcelProperty(value = {"人员信息","年龄"}, index = 1) private int age; @ExcelProperty(value = {"人员信息","性别"}, index = 2) private int

有兴趣关注一下我的个人公众号,专注dotNet开发,谢谢 这个问题几乎面试的时候都会问到,是一个老生常谈的话题,然而随着不断的学习,对于以前的认识有很多误区,所以还是需要不断地总结的,学而时习之,不亦说乎。 什么是http? get、post常见的区别 get和post不同点的误区 附录常见的http状态码 1.什么是http 这里只是简单概述一下,更多详情可以参见: 基于tcp/ip、一种网络应用层协议、超文本传输协议HyperText Transfer Protocol 工作方式:客户端请求服务端应答的模式 快速:无状态连接,灵活:可以传输任意对象,对象类型由Content-Type标记 客户端请求request消息包括以下格式:请求行(request line)、请求头部(header)、空行、请求数据,如下图 服务端响应response也由四个部分组成,分别是:状态行、消息报头、空行、响应正文 请求方法,http请求可以使用多种请求方法。 HTTP1.0定义了三种请求方法: GET, POST 和 HEAD方法。 HTTP1.1新增了五种请求方法:OPTIONS, PUT, DELETE, TRACE 和 CONNECT 方法。 序号 方法 描述 1 GET 请求指定的页面信息,并返回实体主体。 2 HEAD 类似于get请求,只不过返回的响应中没有具体的内容,用于获取报头

.htaccess file to remove .html from url not working

自古美人都是妖i 提交于 2020-01-24 21:02:48
问题 I'm trying to get rid of the .html in the url of pages, and I found that code in the .htaccess file is the only way doing so and I've tried nearly every method and code online but it just wouldn't work. Made an .htaccess file and put it in the public_html file. The general code I'm using is: RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^([^.]+)$ $1.html [NC,L] But I've tried many many many other variations of the code so I think the issue isn't with the code but the way
