Java封装httpGet方法和C#封装httpGet入门级别的问题 | 代码转化：Java -》 C#
我需要c# 用httpclient实现的例子。 system.net.http.
//public static HttpClientResult httpGet(string url, IDictionary<string, string> headMap)
public static string httpGet(string url, IDictionary<string, string> headMap)
{
string response = "";
HttpGet httpGet = null;
CloseableHttpResponse ht = null;
try
{
httpGet = new HttpGet(url);
if (headMap != null && headMap.Count > 0)
{
foreach (string name in headMap.Keys)
{
httpGet.addHeader(name, headMap[name]);
}
}
CloseableHttpClient hc = HttpClients.createDefault();
RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(30000).setConnectTimeout(30000).build(); //设置请求和传输超时时间
httpGet.Config = requestConfig;
ht = hc.execute(httpGet);
HttpEntity het = ht.Entity;
InputStream @is = het.Content;
BufferedReader br = new BufferedReader(new InputStreamReader(@is, "utf8"));
string readLine;
while ((readLine = br.readLine()) != null)
{
response = response + readLine;
}
@is.close();
br.close();
int status = ht.StatusLine.StatusCode;
//return new HttpClientResult(status, response);
return null;
}
catch (Exception e)
{
throw new HttpClientException(e);
}
finally
{
if (httpGet != null)
{
httpGet.releaseConnection();
}
if (ht != null)
{
try
{
ht.close();
}
catch (IOException)
{
}
}
}
}
这是一段java里封装httpget的方法，有没有人能帮忙翻译成C#相应的代码，让我作为示例代码，学习一下。我是做java的，对C#非常不熟。
大神辛苦了，这个问题对大神来说肯定很简单，只要核心代码翻译一下就好，异常啥的就不要啦，最好C#流的常用类也能指点下

public static HttpClientResult httpGet(string url, IDictionary<string, string> headMap)
{
string response = "";
try
{
HttpClient hc = new HttpClient();
hc.Timeout = new System.TimeSpan(300);
if (headMap != null && headMap.Count > 0)
{
foreach (string name in headMap.Keys)
{
hc.DefaultRequestHeaders.Add(name,headMap[name]);
}
}
var getTask = hc.GetAsync(new Uri(url));
HttpResponseMessage responseM = hc.GetAsync(new Uri(url)).Result;
Stream instream = responseM.Content.ReadAsStreamAsync().Result;
BufferedStream bfs = new BufferedStream(instream);
byte[] buffer = new byte[1024];
StringBuilder sb = new StringBuilder();
while (bfs.Read(buffer, 0, buffer.Length) > 0)
{
sb.Append(Encoding.GetEncoding("UTF-8").GetString(buffer));
}
response = sb.ToString();
bfs.Flush();
bfs.Close();
instream.Close();
int statusCode = (int)responseM.StatusCode;
return new HttpClientResult(statusCode, response);
}
catch (HttpRequestException e)
{
throw new HttpRequestException("HttpRequestException");
}
finally
{
}
}
