窗体调用第三方接口

一.

        private void button1_Click(object sender, EventArgs e)
        {
            string url = "localhost";
            byte[] responseArray = null;
            using (WebClient webClient = new WebClient())
            {
                webClient.Headers.Add("jsonStr", "");
                NameValueCollection postValues = new NameValueCollection();
                responseArray = webClient.UploadValues(url, postValues);
            }
            string response = Encoding.UTF8.GetString(responseArray);
            if (!string.IsNullOrEmpty(response) && !response.Equals("null"))
            {
                //result = JsonConvert.DeserializeObject<BaseElseResut>(response);
                //if (result != null && result.Data != null && result.Data.success)
                //{
                //    Response.Write("<script language=javascript>window.location.href='" + result.Data.Reason + "';</script>");
                //}
                //else
                //{
                //    Response.Write("<script>alert('" + result.Data.Reason + "');</script>");
                //}
            }
        }

二、

public string aa()
{
string url = "http://localhost";
byte[] responseArray = null;
using (WebClient webClient = new WebClient())
{
    webClient.Headers.Add("usercode", "a");
    webClient.Headers.Add("username", "b");
    NameValueCollection postValues = new NameValueCollection();
    postValues.Add("a", a);
    postValues.Add("b", b);
    postValues.Add("c", c);
    postValues.Add("d", d);
    postValues.Add("c", c);
    responseArray = webClient.UploadValues(url, postValues);
}
string response = Encoding.UTF8.GetString(responseArray);
if (!string.IsNullOrEmpty(response) && !response.Equals("null"))
{
 result = JsonConvert.DeserializeObject<BaseElseResut>(response);
}
}

　　

三、

public void  PostTest()
{
    string url = "http://localhost:8009/";
    Dictionary<string, object> dic = null;
    string strParams = JsonConvert.SerializeObject(dic);//ParsToString(pairs);
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
    //请求方式POST
    request.Method = "POST";
    //传输数据JSON类型
    request.ContentType = "application/json;charset=utf-8";
    request.Credentials = CredentialCache.DefaultCredentials;
    byte[] bytes = Encoding.Default.GetBytes("userName:Password");
    var strAuthorization = Convert.ToBase64String(bytes);
    request.Headers.Add("Authorization", strAuthorization);
    //请求超时时间，10分钟
    request.Timeout = 600000;
    AddHeaderParams(request);
    //写入数据
    var data = Encoding.UTF8.GetBytes(strParams);
    request.ContentLength = data.Length;
    Stream writer = request.GetRequestStream();
    writer.Write(data, 0, data.Length);
    writer.Close();
    //请求返回数据
    StreamReader reader = new StreamReader(request.GetResponse().GetResponseStream(), Encoding.UTF8);
    string ret = reader.ReadToEnd();
    reader.Close();
}

/// <summary>
/// 添加通用的Header参数
/// </summary>
/// <returns></returns>
private void AddHeaderParams(HttpWebRequest request)
{
    Dictionary<string, string> pairs = new Dictionary<string, string>() {
        { "a", "1" } ,
        { "b", "2" },
        { "c", "3" },
        { "d", DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss")}
    };
    foreach (string key in pairs.Keys)
    {
        request.Headers.Add(key, pairs[key]);
    }
}
