C# asp.net GET POST添加请求头 以及 POST带参数请求 页面间传值 清空Session Cookie

7.C# ASP.NET GET POST添加请求头 以及 POST带参数请求

这里接接口时未进行封装，记录时才临时做了一下，所以可能某些声明不太对。如果有问题自己看着微调下就好，不行就问。

(1)GET添加请求头Token

//根据接收的参数先创建个类
public class getSchoolData
{
	public string OrganizeId { get; set; }
}

public string HttpGet (string url)		
{
	string result = string.Empty;
	HttpWebRequest reqS = (HttpWebRequest)WebRequest.Create(Url);
    reqS.Method = "GET";

 	//添加请求头
	reqS.Headers.Add("Authorization", "Bearer " + accessToken);
	reqS.ContentType = "application/json; charset=utf-8";

    HttpWebResponse resS = (HttpWebResponse)reqS.GetResponse();
	Stream myResponseStream = resS.GetResponseStream();
    StreamReader streamReader = new StreamReader(myResponseStream);
    result = streamReader.ReadToEnd();
    streamReader.Close();
    myResponseStream.Close();

	//Response.Write(result.ToString()); 这里可以看看返回的数据啦~

	 // 解析返回的json数据（使用 jobject）
	JObject theResult = (JObject)JsonConvert.DeserializeObject(result);

	// 根据JSON结构自己修改{}里的key值
	string finalResult = theResult["{Data}"].ToString();

	// 此处需自己根据返回数据设置类去接收 json转实体
	List<getSchoolData> listS = JsonConvert.DeserializeObject<List<getSchoolData>>(finalResult);

	 // 得到返回的数据结果
	foreach (getSchoolData s in listS) 
	{ 
		Response.Write("这里的{s}就是每一条得到的数据啦") 
	}
 }

(2).POST带参数 请求(传入字符串)

public string HttpPost(string url, string content)
{
        string getAccessToken = "";
        HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
        req.Method = "POST";
        req.ContentType = "application/x-www-form-urlencoded";

        //#region 添加Post 参数
        byte[] data = Encoding.UTF8.GetBytes(content);
        req.ContentLength = data.Length;
        using (Stream reqStream = req.GetRequestStream())
        {
            reqStream.Write(data, 0, data.Length);
            reqStream.Close();
        }
        //#endregion

        HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
        Stream stream = resp.GetResponseStream();
        //获取响应内容
        using (StreamReader reader = new StreamReader(stream, Encoding.UTF8))
        {
            getAccessToken = reader.ReadToEnd();
            reader.Close();
        }
        JObject getToken = (JObject)JsonConvert.DeserializeObject(getAccessToken);

        // 同样根据接口规则去取得返回Token
        string getTheToken = getToken["{access_token}"].ToString();
        // 后续操作参上GET
}

8. aspx.cs页面间传值

A.aspx.cs内代码

{
  Session["Access_Token"] = getTheToken;
}

B.aspx.cs内代码

{
	 if (Session["Access_Token"] != null) 
	 {
     	string token = Session["Access_Token"];
	 }
}

9.清除cookie和session

for (int i = 0; i < Response.Cookies.Count; i++)
{
	Response.Cookies[i].Expires = DateTime.Now.AddDays(-1);
}
Session.Clear();
Session.Abandon();
