调用接口出错：https://api.weixin.qq.com/cgi-bin/midas/sandbox/pay?access_token=ACCESS_TOKEN 出错代码： { errcode: 90009,   errmsg: 'mp_sig error hint: [x0kHWa08621092]' } 第一：已经根据 https://developers.weixin.qq.com/minigame/dev/tutorial/open-ability/midas-signature.html 对自己的签名方法进行了测试，结果正确。 ---------check the nodejs crypt sha256 sign method with digest ('hex') the target is :1ad64e8dcb2ec1dc486b7fdf01f4a15159fc623dc3422470e51cf6870734726b the sig result:1ad64e8dcb2ec1dc486b7fdf01f4a15159fc623dc3422470e51cf6870734726b ---------the sha256 digest with ('hex') sig check is success! ---------check the nodejs crypt sha256 sign method with digest ('hex') the target is :ff4c5bb39dea1002a8f03be0438724e1a8bcea5ebce8f221f9b9fea3bcf3bf76 mp_sig  result:ff4c5bb39dea1002a8f03be0438724e1a8bcea5ebce8f221f9b9fea3bcf3bf76 ---------the sha256 digest with ('hex') mp_sig check is success! 第二：测试pay接口有几个疑问。 1、post options的参数是否设置正确？ const post_sandbox_options = { hostname: 'api.weixin.qq.com', port: 443, path: '/cgi-bin/midas/sandbox/pay?access_token=' + access_token, method: 'POST', headers: { 'Content-Type':'application/json', 'Content-Length':post_sandbox_body.length, } }; 2、post的body数据，是不是要包含access_token? {"access_token":"17_4uVhw70eDY0NwVVt1yXw8tbPPgmfDc-Z6mmiM_-DyCFo6vLhRiy8PRF1r_nbNfqNhfqj3uoc3qpjoErDqLSQ3elElITaaYyk03K3Yfe_2Xj-GoZpDx6bWamVhEUOIOZzRpwyImBaKUcutsmSIGNdAFAXVC", "amt":10, "appid":"wxf1453401f1893750", "bill_no":"angus123", "offer_id":"1450019397", "openid":"otyb-4_WbtJc0W6va70J8sbMWGps", "pf":"android", "ts":1548338038, "zone_id":"1", "sig":"795a63ba873783438aeca33790f05f3b2de7e16fa4a23fd33131d48e2402fef9", "mp_sig":"657ea92d78a53e5d3dfca18d3b7190fed0c154182bdd14755d70ced92283d665" } 3、post的url路径是不是正确 https://api.weixin.qq.com/cgi-bin/midas/sandbox/pay?access_token=17_4uVhw70eDY0NwVVt1yXw8tbPPgmfDc-Z6mmiM_-DyCFo6vLhRiy8PRF1r_nbNfqNhfqj3uoc3qpjoErDqLSQ3elElITaaYyk03K3Yfe_2Xj-GoZpDx6bWamVhEUOIOZzRpwyImBaKUcutsmSIGNdAFAXVC 这里卡了一天了，请帮忙看一下。 谢谢！
