使用Joson的格式字符串在Socket中通讯时数据格式的转换
最近在测试通讯模块时,发现新增的Android平台发送过来的数据,服务器端总是收不到,后来发现java中数据类型有些和C#中的不一样,比如C#中byte对应范围是0~255,而Java中则对应的是-128~127,因此直接按照通讯协议传序列化的二进制流总是出现问题。考虑到这一点在Android那一端才用Joson序列化发送到服务端,而在服务端对接收到的数据进行反序列化后转化为对象。同时在服务端进行发送数据时,转换为Joson格式后,序列化为二进制流发生给Android端。
废话不多说了,上代码:
//Joson格式的二进制流转换为对象
public static T JosonDeSerializer<T>(byte[] buffer, int length)
{
try
{
string mTextReceived = Encoding.UTF8.GetString(buffer, 0, length);
//将获取到的Joson格式字符串转换为数据包类
SocketDataPack sdp = GetSocketDataPackFromString(mTextReceived);
MemoryStream stream = new MemoryStream();
BinaryFormatter formatter = new BinaryFormatter();
//将数据包类序列化
formatter.Serialize(stream, sdp);
stream.Position = 0;
stream.Flush();
//转换为对象
object obj = formatter.Deserialize(stream);
if (obj == null)
{
return default(T);
}
return (T)obj;
}
catch (Exception ex)
{
throw ex;
}
}
//对象转换为Joson格式二进制流
public static byte[] JosonSerializer(object input)
{
try
{
JavaScriptSerializer jsonSerializer = new JavaScriptSerializer();
string strSocketDataPack = jsonSerializer.Serialize(input);
byte[] buffer = Encoding.UTF8.GetBytes(strSocketDataPack);
return buffer;
}
catch (Exception ex)
{
throw ex;
}
}
/// <summary>
/// 将Json格式的字符串转换为指定的数据包类
/// </summary>
/// <param name="context"></param>
/// <returns></returns>
private static SocketDataPack GetSocketDataPackFromString(string context)
{
try
{
SocketDataPack sdp = new SocketDataPack();
context = context.Replace("{", "").Replace("[", "").Replace("]", "").Replace("}", "").Replace("\"", "").Replace("\0","");
String[] str = context.Split(',');
for (int i = 0; i < str.Length; i++)
{
String[] str2 = str[i].Split(':');
switch (str2[0])
{
case "Length":
sdp.Length = Convert.ToInt16(str2[1]);
break;
case "Head":
sdp.Head = Convert.ToByte(str2[1]);
break;
