C# Get/Post 模拟提交的相关文章

.Net模拟提交表单

2016-09-0210:49:20 以中邮速递API为服务接口,由于提交方式为表单提交,我要获取返回值来处理其他业务,所以一开始尝试采用Js后台获取返回值,但是涉及到跨域请求限制问题,那边服务端接口返回的是json而不能处理jsonp:所以开始着手考虑后台模拟提交表单: 网上开始查资料,对于后台提交表单的一些相关资料: 表单提交协议规定: 对于含文件的表单提交,要先将 HTTP 要求的 Content-Type 设为 multipart/form-data,而且要设定一个 boundary 参

通过C#的HttpClient模拟提交form()表单

post提交表单一般无非是一般text文本和文件类型,如下 <input type="file"/> <input type="text"/> 如果模拟post提交表单的过程,该怎么做呢 这里就需要用到HttpClietn类 首先我们需要一个类去包装这些需要上载的数据,例如 /// <summary> /// 包装Data数据的Model /// </summary> public class SendData { /

关于libcurl模拟提交form

因为本人对web机制了解较少,在使用C/libcurl中遇到了很多问题.主要的解决方式: 1,在网页源码中找到提交form的定位.也就是网页文件对应form中的action属性.往往都是提交到jsp或者php等脚本中运行的,而不是直接提交到本网页. 2,要注意http头.http头的不同会引起网页的不同反应.我做的一个小项目,在提交到两个网址php脚本时,都因为http头引起php脚本执行不正确. 3,重定向问题. 在一些网页中,返回的网页数据会带有重定向信息,这时要打开curl_easy_se

delphi使用IdHTTP模拟提交页面方法总结

http://blog.csdn.net/lxdcyh/article/details/3986800 1.拖入TIdHTTP控件,HandleRedirect设为True,否则可能会出现HTTP 307错误. 2.主要的设置在Request里.2.1 userAgent应该改为Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 2.0.50727; .NET CLR 3.0.04506.30; CIBA; MAXTHON 2.

php 使用curl 进行简单模拟提交表单

//初始化curl $ch = curl_init(); $url = 'xxx'; $option = [ CURLOPT_URL => $url, CURLOPT_HEADER => 1, CURLOPT_RETURNTRANSFER => 1, ]; curl_setopt_array($ch, $option); $output = curl_exec($ch); preg_match_all('/Set-Cookie: (.*);/i', $output, $str); //正

php curl模拟post请求提交数据

最近在做校园图书馆图书信息的采集程序,既然是图书馆图书的采集,肯定有提交搜索的页面,无非是post提交,让我想到了curl模拟提交,首先通过firebug进行抓包查询下post提交后的格式如下: txtWxlx=CN&hidWxlx=spanCNLx&txtPY=HZ&txtTm=%D2%F4%C0%D6&txtLx=%25&txtSearchType=1&nMaxCount=100&nSetPageSize=10&cSortFld=%D5%

ASP模拟POST请求异步提交数据的方法

这篇文章主要介绍了ASP模拟POST请求异步提交数据的方法,本文使用MSXML2.SERVERXMLHTTP.3.0实现POST请求,需要的朋友可以参考下 有时需要获取远程网站的某些信息,而服务器又限制了GET方式,只能通过POST数据提交,这个时候我们可以通过asp来实现模拟提交post数据,网上有挺多这样的例子的.下面的是我自己写的比较简洁易懂的函数. 首先,需要一个编码设置的函数,因为asp一般为gbk的,而标准的网站现在大都使用utf-8的.所以需要转换. 代码如下: function

CURL模拟POST提交的二种方法实例

CURL应用广范,本文来介绍CURL模拟POST提交的二种方法实例,他们都是返回json字符串格式. 方法一(返回的是json字符串格式): /** * Curl版本 * 使用方法: * $post_string = "app=request&version=beta"; * request_by_curl('http://facebook.cn/restServer.php',$post_string); */ function actionPost($url,$data){
