Question

c#怎么访问java写得api

Answer 1

Encoding code = Encoding.GetEncoding("utf-8");

//待弊神扮请求参数数组字符串
string strRequestData = "";

//把数组转换成流中所需字节数组类型
byte[] bytesRequestData = code.GetBytes(strRequestData);

//构造请求地址
string strUrl = "http://www.xxx.com/api/xxx.do";

//请求远程HTTP
string strResult = "";
try
{
//设置HttpWebRequest基本信息
HttpWebRequest myReq = (HttpWebRequest)HttpWebRequest.Create(strUrl);
myReq.Method = "post";
myReq.ContentType = "application/x-www-form-urlencoded";

//填充POST数据
myReq.ContentLength = bytesRequestData.Length;
Stream requestStream = myReq.GetRequestStream();
requestStream.Write(bytesRequestData, 0, bytesRequestData.Length);
requestStream.Close();

//发送POST数据请求服务器
HttpWebResponse HttpWResp = (HttpWebResponse)myReq.GetResponse();
Stream myStream = HttpWResp.GetResponseStream();

//获取服务器返瞎察回信息
StreamReader reader = new StreamReader(myStream, code);
StringBuilder responseData = new StringBuilder();
String line;
while ((line = reader.ReadLine()) != null)
{
responseData.Append(line);
}

//释租灶放
myStream.Close();

strResult = responseData.ToString();
}
catch (Exception exp)
{
strResult = "报错：" + exp.Message;
}
