    C#中HttpWebRequest的用法详解

    HttpWebRequest和HttpWebResponse类是用于发送和接收HTTP数据的最好选择。它们支持一系列有用的属性。这两个类位 于System.Net命名空间，默认情况下这个类对于控制台程序来说是可访问的。请注意，HttpWebRequest对象不是利用new关键字通过构 造函数来创建的，而是利用工厂机制（factory mechanism）通过Create()方法来创建的。另外，你可能预计需要显式地调用一个“Send”方法，实际上不需要。接下来调用 HttpWebRequest.GetResponse()方法返回的是一个HttpWebResponse对象。你可以把HTTP响应的数据流 （stream）绑定到一个StreamReader对象，然后就可以通过ReadToEnd()方法把整个HTTP响应作为一个字符串取回。也可以通过 StreamReader.ReadLine()方法逐行取回HTTP响应的内容。

    这种技术展示了如何限制请求重定向（request redirections）的次数， 并且设置了一个超时限制。下面是HttpWebRequest的一些属性，这些属性对于轻量级的自动化测试程序是非常重要的。

    l  AllowAutoRedirect：获取或设置一个值，该值指示请求是否应跟随重定向响应。

    l  CookieContainer：获取或设置与此请求关联的cookie。

    l  Credentials：获取或设置请求的身份验证信息。

    l  KeepAlive：获取或设置一个值，该值指示是否与 Internet 资源建立持久性连接。

    l  MaximumAutomaticRedirections：获取或设置请求将跟随的重定向的最大数目。

    l  Proxy：获取或设置请求的代理信息。

    l  SendChunked：获取或设置一个值，该值指示是否将数据分段发送到 Internet 资源。

    l  Timeout：获取或设置请求的超时值。

    l  UserAgent：获取或设置 User-agent HTTP 标头的值

    C# HttpWebRequest提交数据方式其实就是GET和POST两种，那么具体的实现以及操作注意事项是什么呢？那么本文就向你详细介绍C# HttpWebRequest提交数据方式的这两种利器。

    C# HttpWebRequest提交数据方式学习之前我们先来看看什么是HttpWebRequest，它是 .net 基类库中的一个类，在命名空间 System.Net 下面，用来使用户通过HTTP协议和服务器交互。

    C# HttpWebRequest的作用：

    HttpWebRequest对HTTP协议进行了完整的封装，对HTTP协议中的 Header, Content, Cookie 都做了属性和方法的支持，很容易就能编写出一个模拟浏览器自动登录的程序。

    C# HttpWebRequest提交数据方式：

    程序使用HTTP协议和服务器交互主要是进行数据的提交，通常数据的提交是通过 GET 和 POST 两种方式来完成，下面对这两种方式进行一下说明：

    C# HttpWebRequest提交数据方式1. GET 方式。

    GET 方式通过在网络地址附加参数来完成数据的提交，比如在地址 http://www.google.com/webhp?hl=zh-CN 中，前面部分 http://www.google.com/webhp 表示数据提交的网址，后面部分 hl=zh-CN 表示附加的参数，其中 hl 表示一个键(key)， zh-CN 表示这个键对应的值(value)。程序代码如下：

    HttpWebRequest req =  

    (HttpWebRequest) HttpWebRequest.Create(  

    "http://www.google.com/webhp?hl=zh-CN" ); 

    req.Method = "GET"; 

    using (WebResponse wr = req.GetResponse()) 

    { 

       //在这里对接收到的页面内容进行处理 

    }

    C# HttpWebRequest提交数据方式2. POST 方式。

    POST 方式通过在页面内容中填写参数的方法来完成数据的提交，参数的格式和 GET 方式一样，是类似于 hl=zh-CN&newwindow=1 这样的结构。程序代码如下：

    string param = "hl=zh-CN&newwindow=1";        //参数

    byte[] bs = Encoding.ASCII.GetBytes(param);    //参数转化为ascii码

    HttpWebRequest req =   (HttpWebRequest) HttpWebRequest.Create(   "http://www.google.com/intl/zh-CN/" );  //创建request

    req.Method = "POST";    //确定传值的方式，此处为post方式传值

    req.ContentType = "application/x-www-form-urlencoded"; 

    req.ContentLength = bs.Length; 

    using (Stream reqStream = req.GetRequestStream()) 

    { 

       reqStream.Write(bs, 0, bs.Length); 

    } 

    using (WebResponse wr = req.GetResponse()) 

    { 

       //在这里对接收到的页面内容进行处理 

    } 

    在上面的代码中，我们访问了 www.google.com 的网址，分别以 GET 和 POST 方式提交了数据，并接收了返回的页面内容。然而，如果提交的参数中含有中文，那么这样的处理是不够的，需要对其进行编码，让对方网站能够识别。

    C# HttpWebRequest提交数据方式3. 使用 GET 方式提交中文数据。

    GET 方式通过在网络地址中附加参数来完成数据提交，对于中文的编码，常用的有 gb2312 和 utf8 两种，用 gb2312 方式编码访问的程序代码如下：

    Encoding myEncoding = Encoding.GetEncoding("gb2312");     //确定用哪种中文编码方式

    string address = "http://www.baidu.com/s?"   + HttpUtility.UrlEncode("参数一", myEncoding) +  "=" + HttpUtility.UrlEncode("值一", myEncoding);       //拼接数据提交的网址和经过中文编码后的中文参数

    HttpWebRequest req =   (HttpWebRequest)HttpWebRequest.Create(address);  //创建request

    req.Method = "GET";    //确定传值方式，此处为get方式

    using (WebResponse wr = req.GetResponse()) 

    { 

       //在这里对接收到的页面内容进行处理 

    } 

    在上面的程序代码中，我们以 GET 方式访问了网址 http://www.baidu.com/s ，传递了参数“参数一=值一”，由于无法告知对方提交数据的编码类型，所以编码方式要以对方的网站为标准。常见的网站中， www.baidu.com （百度）的编码方式是 gb2312, www.google.com （谷歌）的编码方式是 utf8。

    C# HttpWebRequest提交数据方式4. 使用 POST 方式提交中文数据。

    POST 方式通过在页面内容中填写参数的方法来完成数据的提交，由于提交的参数中可以说明使用的编码方式，所以理论上能获得更大的兼容性。用 gb2312 方式编码访问的程序代码如下：

    Encoding myEncoding = Encoding.GetEncoding("gb2312");  //确定中文编码方式。此处用gb2312

    string param =   HttpUtility.UrlEncode("参数一", myEncoding) +   "=" + HttpUtility.UrlEncode("值一", myEncoding) +   "&" +     HttpUtility.UrlEncode("参数二", myEncoding) +  "=" + HttpUtility.UrlEncode("值二", myEncoding); 

    byte[] postBytes = Encoding.ASCII.GetBytes(param);     //将参数转化为assic码

    HttpWebRequest req = (HttpWebRequest)  HttpWebRequest.Create( "http://www.baidu.com/s" ); 

    req.Method = "POST"; 

    req.ContentType =   "application/x-www-form-urlencoded;charset=gb2312"; 

    req.ContentLength = postBytes.Length; 

    using (Stream reqStream = req.GetRequestStream()) 

    { 

       reqStream.Write(bs, 0, bs.Length); 

    } 

    using (WebResponse wr = req.GetResponse()) 

    { 

       //在这里对接收到的页面内容进行处理 

    }  

    从上面的代码可以看出， POST 中文数据的时候，先使用 UrlEncode 方法将中文字符转换为编码后的 ASCII 码，然后提交到服务器，提交的时候可以说明编码的方式，用来使对方服务器能够正确的解析。

    以上列出了客户端程序使用HTTP协议与服务器交互的情况，常用的是 GET 和 POST 方式。现在流行的 WebService 也是通过 HTTP 协议来交互的，使用的是 POST 方法。与以上稍有所不同的是， WebService 提交的数据内容和接收到的数据内容都是使用了 XML 方式编码。所以， HttpWebRequest 也可以使用在调用 WebService 的情况下。

    C# HttpWebRequest提交数据方式的基本内容就向你介绍到这里，希望对你了解和学习C# HttpWebRequest提交数据方式有所帮助。
