很久不更新博客了,这次大概说一下C#中的Send WebRequest,众所周知,.NET网络编程在测试中是非常常见的,具体来说,比如我们如果测试一个API,通过Send WebRequest的方式来进行API层面的功能测试,然后用Selenium完成前端的验证,这种模式应该说是比较方便而通用的,具体以其中最常见的HTTP request为例,当我们需要传输数据时,需要
1)地址:Address作为Webrequest参数实例化,然后设定相应属性,比如Method(Get还是Post等等)
2)数据:Data作为HttpRequest的数据流写入:
XmlResponse = null;
ResponseCode = HttpStatusCode.Unused;
ServerResponse = String.Empty;
参数处理部分
//Format the data
string output = data.Aggregate(String.Empty, (current, keyValuePair) => current + ("&" + keyValuePair.Key + "=" + HttpUtility.UrlEncode(keyValuePair.Value)));
var encoding = new UTF8Encoding();
//设置PostData变量将output进行处理,最终得到byte[] d作为最终数据写入到WebRequest中
var Postdata = Encoding.ASCII.GetBytes(output);
byte[] d = encoding.GetBytes(output.Substring(1, output.Length - 1));
var address = TargetUrl;
//GET部分的数据处理
if (method.ToUpperInvariant() == "GET")
address=address+output;
//POST部分的数据处理
WebRequest request = WebRequest.Create(address) as HttpWebRequest;
//Add post process
if (request == null)
throw new Exception("WebRequest object is null.");
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = d.Length;
ServerResponse = String.Empty;
//数据读取及处理部分
using (Stream dataStream = request.GetRequestStream())
{
dataStream.Write(d, 0, d.Length);
dataStream.Close();
using (var response = (HttpWebResponse)request.GetResponse())
{
ResponseCode = response.StatusCode;
using (Stream myStream = response.GetResponseStream())
{
if (myStream != null)
{
var readStream = new StreamReader(myStream, Encoding.UTF8);
ServerResponse = readStream.ReadToEnd();
}
}
response.Close();
}
}
if (ResponseCode == HttpStatusCode.OK)
{
if (loadXml)
LoadXml();
return true;
}
return false;
