signature calculated is different from
遇到一个问题，是在云函数端的错误。
代码是这样的，在云函数端更改一个数据记录。
var handleGoods =function(goods,storenum){ var _ = db.command; return db.collection('goods').doc(goods._id).update({ data:{ store_num:_.inc(storenum*-1), sale_num:_.inc(storenum) } });} |
结果是
Error: errCode: -501001 resource system error | errMsg: signature calculated is different from client signature; at new CloudSDKError (/Users/skymxc/Documents/project/WeChat/shop/cloudfunctions/handleOrder/node_modules/wx-server-sdk/index.js:4332:28) at Object.returnAsCloudSDKError (/Users/skymxc/Documents/project/WeChat/shop/cloudfunctions/handleOrder/node_modules/wx-server-sdk/index.js:4384:16) at Object.checkError (/Users/skymxc/Documents/project/WeChat/shop/cloudfunctions/handleOrder/node_modules/wx-server-sdk/index.js:1401:23) at DocumentReference.<anonymous> (/Users/skymxc/Documents/project/WeChat/shop/cloudfunctions/handleOrder/node_modules/wx-server-sdk/index.js:1334:41) at step (/Users/skymxc/Documents/project/WeChat/shop/cloudfunctions/handleOrder/node_modules/tslib/tslib.js:133:27) at Object.next (/Users/skymxc/Documents/project/WeChat/shop/cloudfunctions/handleOrder/node_modules/tslib/tslib.js:114:57) at fulfilled (/Users/skymxc/Documents/project/WeChat/shop/cloudfunctions/handleOrder/node_modules/tslib/tslib.js:104:62) at <anonymous> at process._tickCallback (internal/process/next_tick.js:188:7) |
返回的错误是 signature calculated is different from client signature; 签名和客户端不同
因为是在云函数端，也不存在权限问题吧。很是不解。
有没有大神帮忙看一下子，万分感谢。
