//1.首先执行参数验证，如果参数提供有误，会抛出异常
request.Validate();
//2.得到请求的所有参数字典,调用request.GetParameterDict()可以获得Request的应用参数，同时要将SYS_PARAMETER_DICT系统参数也加入
Dictionary <string, string> paramterDict = request.GetParameterDict()
.Concat(WechatPaymentConfig.SYS_PARAMETER_DICT).ToDictionary(k => k.Key, v => v.Value);
//3.将参数字典的key值按字母顺序排序（按ASCII排序，例如a在b前面）
SortedDictionary <string, string> sortedParameterDict = SortDictionaryConverter.Convert(paramterDict);
//4.拼接计算Sign参数
string sign = SignBulider.Generate(sortedParameterDict, WechatPaymentConfig.SECRET);
//5.将sign参数加入到参数字典中
paramterDict.Add("sign", sign);
//6.将paramterDict字典转化为XML格式
string requestXml = XmlStringBulider.Generate(paramterDict);
//7.提交请求到微信服务器，获取响应的字符串
//HACK(Teroy):退款API在POST的时候要带证书,其他API请求不用
string responseXml = request.IsPostRequireCertificate ?
HttpRequestWrapper.PostXmlWithCertificate(request.ApiUrl, requestXml) : HttpRequestWrapper.PostXml(request.ApiUrl, requestXml);

//9.将响应的XML数据预存到Body中
