public static string url = "http://localhost:8080/film/";

public void Login(string username , string password)
	{	
		string path = "/film/api/tqh/v2/member/login";
		StartCoroutine(PostLogin(url+"api/tqh/v2/member/login?",path,username,password));		
	}

IEnumerator PostLogin(string url,string path,string username , string password)

		WWWForm form = new WWWForm();		
		Hashtable headers = form.headers;
		byte[] rawData = Encoding.UTF8.GetBytes(input);
		headers["Content-Type"] = "application/json";
		headers["Accept"] = "application/json";

		DateTime date = DateTime.Now;
		string time =  date.ToString("ddd, yyyy-mm-dd HH':'mm':'ss 'UTC'",DateTimeFormatInfo.InvariantInfo);
		headers["Date"] = time;
		url = hmac(url,path,time);

		WWW www = new WWW(url, rawData, headers);
		yield return www;		
		if (www.error != null)
		{
			Debug.Log("error is login:"+ www.error  + "  " +input );	
			camara.GetComponent<loginGUI>().loginfail(status_fail);
		} else
		{
			Debug.Log("request ok login: " + www.text);

			JsonData jd = JsonMapper.ToObject(www.text); 

			string memberId = jd["memberId"].ToString();
			string bonusPoint = jd["bonusPoint"].ToString();
			string nickName = jd["nickName"].ToString();
			camara.GetComponent<loginGUI>().loginsuccess(memberId,nickName,bonusPoint,status_success);
		}
	}

oauth使用在headers中加入Date，date.ToString("ddd, yyyy-mm-dd HH':'mm':'ss 'UTC'",DateTimeFormatInfo.InvariantInfo)对日期的格式化

string time =  date.ToString("ddd, yyyy-mm-dd HH':'mm':'ss 'UTC'",DateTimeFormatInfo.InvariantInfo);

headers["Date"] = time;

www.text为后台返回的String字符串，是Json格式，但是不可以直接用key-value去取值，我们需要去转换使用LitJson，一个第三方插件

JsonData jd = JsonMapper.ToObject(www.text); 

string memberId = jd["memberId"].ToString();
string bonusPoint = jd["bonusPoint"].ToString();
string nickName = jd["nickName"].ToString();

在unity\项目\Assets\Plugins目录下引用LitJson，下载LitJson

之后就可以用key-value去取值了   

oauth的加入

public static  string API_KEY = "bc543dc89b***********";
public  static string SECURE_KEY = "32df2bc3520d53a1************";

	public string hmac(string url ,string path ,string time){
		StringBuilder stringToSign = new StringBuilder();
		stringToSign.Append("POST").Append("\n");
		stringToSign.Append(time).Append("\n");
		stringToSign.Append(path).Append("\n");	

		var signature = string.Empty;
		using (var hmac = new HMACSHA512(Encoding.UTF8.GetBytes(SECURE_KEY)))
		{
			var hash = hmac.ComputeHash(Encoding.UTF8.GetBytes(stringToSign.ToString()));
			signature = Convert.ToBase64String(hash);
		}

		StringBuilder s = new StringBuilder();
		s.Append(url);
		s.Append("&apiKey=");
		s.Append(HttpUtility.UrlEncode(API_KEY, Encoding.UTF8));
		s.Append("&signature=");
		s.Append(HttpUtility.UrlEncode(HttpUtility.UrlEncode(signature, Encoding.UTF8), Encoding.UTF8));

		return s.ToString();
	}

StringBuilder stringToSign = new StringBuilder();
stringToSign.Append("POST").Append("\n");
stringToSign.Append(time).Append("\n");
stringToSign.Append(path).Append("\n");

需要通过 httpMethod、time、和path（格式为"/film/api/tqh/v2/public/getAllHistoryRank"）来获取HMACSHA512加密后的签名

var hmac = new HMACSHA512(Encoding.UTF8.GetBytes(SECURE_KEY))

对API_KEY和签名进行编码，签名编码两次是因为，在服务器被解码了两次一次jetty、一次后台

StringBuilder s = new StringBuilder();s.Append(url);s.Append("&apiKey=");s.Append(HttpUtility.UrlEncode(API_KEY, Encoding.UTF8));s.Append("&signature=");s.Append(HttpUtility.UrlEncode(HttpUtility.UrlEncode(signature, Encoding.UTF8), Encoding.UTF8));

HttpUtility使用需要引入的 using System.Web; 下载HttpUtility
