一、 问题出现 :在之前进行 php 开发的时候,使用 phpStudy 工具进行开发,在打开 phpMyAdmin 进行开发时,插入 SQL 语句的时候,出现了 Warning: Unknown: POST Content-Length of 12497347 bytes exceeds the limit of 8388608 bytes in Unknown on line 0 Warning: Cannot modify header information - headers already sent in Unknown on line 0 这个错误,如下图所示: 二、 错误分析及解决 :这个错误出现的原因是文件上传出现错误,所需要上传的文件超出了限制,所以我们需要修改上传文件权限。找到 php.ini 文件,修改两个参数, upload_max_filesize 和 post_max_size 。 upload_max_filesize 的作用是 用于限制用户上传单文件的大小, post_max_size 的作用是 用于限制 POST 请求 body 的大小。最后值的修改大小可以根据实际情况进行修改,下面为示例: 默认的 php.ini 文件: post_max_size = 8 M upload_max_filesize = 2 M 修改后的 php.ini 文件:

Http中的get与post请求的区别

馋奶兔 提交于 2020-02-03 18:09:03
get与post最直观的区别 数据存放位置 : 1.get是把请求的数据放到url最后 2.post是把数据放在header头中 安全性 : 1.get把数据显性暴露在外面,不安全但执行效率却比post 方法好 2.post稍微隐藏下,不会被大型爬虫直接解包,相对安全但也不安全 表单的提交默认是用get,在进行文件上传时只能用post而不能是get 数据量 : 1.get传送数据量较小,get限制1083(其实真正限制的是url的长度,从通信协议角度讲,数据量本身没有限制,而且长度限制只存在于IE浏览器下,谷歌火狐不存在这个问题) 2.post传送的数据量较大,一般默认为不受限制 其实GET与POST本质没有区别,它们是HTTP协议中的两种发送请求的方法。 HTTP是基于TCP/IP的关于数据如何在万维网中如何通信的协议。HTTP的底层是TCP/IP。所以get和post的底层也是TCP/IP,但是由于HTTP的规定和浏览器/服务器的限制,导致它们在应用过程中体现出一些不同。 对于GET方式的请求,浏览器会把http header和data一并发送出去,服务器响应200(返回数据); 而对于POST,浏览器先发送header,服务器响应100 continue,浏览器再发送data,服务器响应200 ok(返回数据)。 简单的说: GET产生一个TCP数据包

C#QQ空间爬虫 并POST批量操作点赞评论回复等 关键参数获得qzonetoken g_tk

软件下载 : 链接: https://pan.baidu.com/s/1IuLs-C7XQVlI42gdS4p7yQ 提取码: 5vgt (因QQ空间升级,目前只能批量点赞。需IE11) 技术分析:先看一个范例 这是我手工评论别人BBBBBB的抓包。 我想模拟POST发送,就要得到上面的所有参数。其它的直接可以得到,主要以下两个参数 1.g_tk 点发表,跟踪js在 https://qzonestyle.gtimg.cn/ac/qzone/qzfl/qzfl_v8_2.1.65.js 的84行 使用js在线格式化工具 https://tool.oschina.net/codeformat/js/ ,搜上面的位置xhr.send(transdata(data))定位到4776行。 找到xhr.open(opt.method, url + (url.indexOf("?") > -1 ? "&": "?") + "g_tk=" + QZFL.pluginsDefine.getACSRFToken(url), true); 是通过url得到的。再看看url url我复制出来 (数据部分我改了一点,规避隐私) https://user.qzone.qq.com/proxy/domain/ic2.qzone.qq.com/cgi-bin/feeds/cgi_get_feeds_count

博客园随笔如何自动生成目录(原理:页脚js函数且执行)

博客园随笔如何自动生成目录(原理:页脚js函数且执行) 一、总结 一句话总结:用的是jquery的dom操作知识,主要操作就是在标题那里添加锚点,然后在目录那里链接到锚点 1、如何在标题前面添加锚点? 用before方法 30 var li3_anchor = '<a name="_label' + i + '_' + j + '"></a>'; //添加锚点 31 $(h3_list[j]).before(li3_anchor); 2、如何在目录那里链接到锚点? a标签的href属性到锚点a标签的name属性 32 li3_content += '<li><a href="#_label' + i + '_' + j + '">' 33 + $(h3_list[j]).text() + '</a></li>'; //链接到锚点 3、将标题插入到开头用的什么方法? prepend内部之前插入方法 99 var title_h1 = $('#cnblogs_post_body h1');//将标题信息插入到开头 100 $(mainContent[0]).prepend(title_h1[0]); 实现原理:在页脚添加了一个js函数,然后调用执行,用了很多类选择器和dom里面的知识, 里面有jquery 二、让博客园博客自动生成章节目录索引 对于比较长的文章
