产品：JSAPI v3 小程序支付功能
接口：JSAPI下单
参考官方文档：https://pay.weixin.qq.com/wiki/doc/apiv3/apis/chapter3_5_1.shtml
请求URL：https://api.mch.weixin.qq.com/v3/pay/transactions/jsapi
---------------------------------------------------------------------------------------------------------------------------------------------------------
问题：直接在postman上调用时报错：Http头Authorization值格式错误，请参考《微信支付商户REST API签名规则》
帮忙看看请求参数或方法哪里调用错了？notify_url 这个参数要满足哪些要求（文档中并没有描述清楚），是不是这个参数有问题呢
dynamic param = new {
"mchid": "1900006XXX",
"out_trade_no": "1217752501201407033233368318",
"appid": "wxdace645e0bc2cXXX",
"description": "Image形象店-深圳腾大-QQ公仔",
"notify_url": "https://www.weixin.qq.com/wxpay/pay.php",
"amount": {
"total": 1,
"currency": "CNY"
},
"payer": {
"openid": "o4GgauInH_RCEdvrrNGrntXDuXXX"
}
};
string method = "POST", uri = "/v3/pay/transactions/jsapi", _timeStamp = getTimeStamp(),_nonce_str = get_nonce_str(),body = JsonHelper.SerializeObject(param);
string message = $"{method}\n{uri}\n{_timeStamp}\n{_nonce_str}\n{body}\n";
// 使用RSA进行签名
string _signature = ComputeSha256Hash(message, _mch_private_key);
string authrizationValue = $"mchid=\"{_mch_id}\",nonce_str=\"{_nonce_str}\",timestamp=\"{_timeStamp}\",serial_no=\"{_serial_no}\",signature=\"{_signature}\"";
HttpRequestMessage httpRequest = new HttpRequestMessage(HttpMethod.Post, jsapi_v3_Url);
httpRequest.Content = new StringContent(body, Encoding.UTF8, "application/json");
httpRequest.Headers.Add("Accept", "application/json");
httpRequest.Headers.Add("ContentType", "application/json");
httpRequest.Headers.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("WECHATPAY2-SHA256-RSA2048", authrizationValue);
using (HttpClient httpClient = new HttpClient())
{
HttpResponseMessage response = await httpClient.SendAsync(httpRequest); //这里就一直没反应，也不报错 $$_$$!
string responseString = await response.Content.ReadAsStringAsync();
}
阁下名字起的真不错，很疯狂
