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
