1、创建Token

    
public void createToken() {
    string APIID = "bl750dac5ad0b81a11";
    string APIKEY = "e8ec47402eebfc315bedfb02014d464d";
    string ReqURL = "https://api.parkline.cc/api/token";
    Dictionary parameters = new Dictionary();
    parameters.Add("apiid", APIID);
    parameters.Add("apikey", APIKEY);
    
    HttpWebResponse res = CreatePostHttpResponse(ReqURL, parameters);
    Stream myResponseStream = res.GetResponseStream();
    StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.GetEncoding("utf-8"));
    string retString = myStreamReader.ReadToEnd();
    
    Response.Write(retString);
    myStreamReader.Close();
    myResponseStream.Close();
}

public HttpWebResponse CreatePostHttpResponse(string url, IDictionary parameters)
{
    HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;//创建请求对象
    request.Method = "POST";//请求方式
    request.ContentType = "application/x-www-form-urlencoded";
    request.Referer = "http://192.168.4.164";   //后台填写的授权接入地址，必须包含http或https协议
    if (!(parameters == null || parameters.Count == 0))
    {
    StringBuilder buffer = new StringBuilder();
    bool first = true;
        foreach (string key in parameters.Keys)
        {
        
            if (!first)
            {
                buffer.AppendFormat("&{0}={1}", key, parameters[key]);
            }
            else
            {
                buffer.AppendFormat("{0}={1}", key, parameters[key]);
                first = false;
            }
        }
        byte[] data = Encoding.UTF8.GetBytes(buffer.ToString());
        //写入请求流
        using (Stream stream = request.GetRequestStream())
        {
            stream.Write(data, 0, data.Length);
        }
    }
    
    return request.GetResponse() as HttpWebResponse;
}

2、发送开锁

public void openLock()
{
    string token = "bhmhL6ap/xZIcWVyc+xw4dVKbfhIcdVDhowqw2rnwdgLmbFxMDJ2XmFA4dG5e6Z6e0bMY3wk1qg=";
    string typeid = "01";
    string devid = "210015";
    string lockid = "01";
    string requrl = "https://api.parkline.cc/api/devicecgi";
    
    Dictionary parameters = new Dictionary();
    parameters.Add("token", UrlEncode(token));
    parameters.Add("typeid", typeid);
    parameters.Add("devid", devid);
    parameters.Add("lockid", lockid);
    
    HttpWebResponse res = CreatePostHttpResponse(requrl, parameters);
    Stream myResponseStream = res.GetResponseStream();
    StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.GetEncoding("utf-8"));
    string retString = myStreamReader.ReadToEnd();
    
    Response.Write(retString);
    myStreamReader.Close();
    myResponseStream.Close();
}

public static string UrlEncode(string str)
{
    StringBuilder sb = new StringBuilder();
    byte[] byStr = System.Text.Encoding.UTF8.GetBytes(str); //默认是System.Text.Encoding.Default.GetBytes(str)
    for (int i = 0; i < byStr.Length; i++)
    {
        sb.Append(@"%" + Convert.ToString(byStr[i], 16));
    }
    
    return (sb.ToString());
}
===============================================================================       

3、图片转BASE64字符


public string ImgToBase64String(string Imagefilename)
{
    try
    {
        Bitmap bmp = new Bitmap(Imagefilename);
        MemoryStream ms = new MemoryStream();
        bmp.Save(ms, System.Drawing.Imaging.ImageFormat.Png);
        byte[] arr = new byte[ms.Length];
        ms.Position = 0;
        ms.Read(arr, 0, (int)ms.Length);
        ms.Close();
        return Convert.ToBase64String(arr);
    }catch (Exception e){
       
    
        return null;
    }
}
===============================================================================       


4、将图片Base64字符串转成图片

public void Base64StringToImage(string strbase64)
{

    try
    {
    byte[] arr = Convert.FromBase64String(strbase64);
    MemoryStream ms = new MemoryStream(arr);
    System.Drawing.Image img = System.Drawing.Image.FromStream(ms);
    string ls_path = Server.MapPath(@"images\huweibing.png");
    img.Save(ls_path, System.Drawing.Imaging.ImageFormat.Png);
    
    }catch (Exception ex){
    
    }
}

提示：其他功能请参考开锁代码
