wx.addCard 签名错误，请求帮助 - WXOPEN Club

当前 Bug 的表现（可附上截图）

1、服务器端签名代码：

var token = ws.GetAccessToken(Appid, Secret);

var timestamp = DateTime.Now.Ticks.ToString().Substring(0, 10);

var jsapi_ticket = Main.GetTicket(token);

string nonce_str = "1000";

string carid = "p1SK9wg2SA3-0JFqzlddT6w53Gnc";

string order = timestamp + jsapi_ticket + carid + nonce_str;

string signature = Main.MakeSha1Sign(order);

ret = ret.Replace("{0}", carid);

ret = ret.Replace("{1}", nonce_str);

ret = ret.Replace("{2}", timestamp);

ret = ret.Replace("{3}", jsapi_ticket);

ret = ret.Replace("{4}", signature);

HttpContext.Current.Response.Write(ret);

通过官方的签名校验工具，顺利通过

2、微信前端代码如下：

{

var timestamp = ""

var signature = ""

var cardid = ""

var nonce_str

wx.request({

url: app.globalData.host + '/action/Handler.ashx?a=ticket&sid=' + app.globalData.shopid,

header: {

'content-type': 'application/json', // 默认值

"X-SQL-AppKey": app.globalData.APPkey

},

success(res) {

if (res.data) {

console.log(res.data)

cardid = res.data.carid

var cardExt={}

cardExt.timestamp = res.data.timestamp

cardExt.signature = res.data.signature

cardExt.nonceStr = res.data.nonce_str

wx.addCard({

cardList: [{

cardId: res.data.carid,

cardExt: JSON.stringify(cardExt)

}, ],

success(res) {

console.log(res.cardList) // 卡券添加结果

}

})

}

})

}

服务器端值正常接收，现在打开提示：签名错误！

服务器端返回代码：

{carid: "p1SK9wg2SA3-0JFqzlddT6w53Gnc", nonce_str: "wxapp", timestamp: "6369869659", ticket: "IpK_1T69hDhZkLQTlwsAX2aXDM0lanFPJGw_1HYYb1bNF-NF70JbgTlOoJahIro2-ifNz4bHRR-8kdH2O4SuYQ", signature: "04f21bd32a7a6d95a504fc066eeb928377a6e564"}

cardExt: JSON.stringify(cardExt)

输出值是这个：

{"timestamp":"6369869659","signature":"04f21bd32a7a6d95a504fc066eeb928377a6e564","nonceStr":"wxapp"}
