業(yè)務(wù)流程在這里大家看文檔的時(shí)候可以看到。第一個(gè)坑，獲取用戶的openid，參數(shù)一定要拼在url連接上，否則會(huì)報(bào){"errcode":40013,"errmsg":"invalid appid, hints: [ req_id: iil1ba0504ns86 ]"}錯(cuò)誤

onLoad: function () {
var that = this
wx.login({
success: function (res) {
if (res.code) {
//發(fā)起網(wǎng)絡(luò)請(qǐng)求
wx.request({
url: '/tupian/20230522/jscode2session
method: "POST",
success: function (res) {
that.setData({
openid: res.data.openid
})
}
})
} else {
console.log('獲取用戶登錄態(tài)失??！' + res.errMsg)
}
}
});
}第二個(gè)坑，支付統(tǒng)一下單接口，簽名這個(gè)坑是比較多人遇到問(wèn)題的這個(gè)是MD5加密經(jīng)常和簽名工具里面的加密簽名不一樣
簽名加密工具地址：/tupian/20230522/404.html>簽名加密的時(shí)候要轉(zhuǎn)成utf-8,加密我用自己的接口進(jìn)行加密的 digest.update(data.getBytes("utf-8"));
// 統(tǒng)一下單接口獲取sign（簽名）
paysignjsapi: function (appid, attach, body, mch_id, nonce_str, notify_url, openid, out_trade_no, spbill_create_ip, total_fee, trade_type, key) {
var self = this;
//加密簽名
wx.request({
url: 'http://localhost:8080/XinXingWXApi/wxXcxApi/Md5Encrypt.do',
method: 'GET',
data: {
appid: appid,
attach: attach,
body: body,
mch_id: mch_id,
nonce_str: nonce_str,
notify_url: notify_url,
openid: openid,
out_trade_no: out_trade_no,
spbill_create_ip: spbill_create_ip,
total_fee: total_fee,
trade_type: trade_type,
key: key
},
//統(tǒng)一下單
success: function (res) {
var sign = res.data.strMd5
var formData = ""
formData += "" + appid + " " //appid
formData += "" + attach + " " //附加數(shù)據(jù)
formData += "" + body + "" //標(biāo)題
formData += "" + mch_id + " " //商戶號(hào)
formData += "" + nonce_str + " " //隨機(jī)字符串，不長(zhǎng)于32位。
formData += "" + notify_url + " " //異步接收微信支付結(jié)果通知的回調(diào)地址
formData += "" + openid + " " //用戶Id
formData += "" + out_trade_no + " " //商戶訂單號(hào)
formData += "" + spbill_create_ip + " "
formData += "" + total_fee + " " //金額
formData += "" + trade_type + " " //公共號(hào)支付
formData += "" + sign + " "http://簽名
formData += " "返回?cái)?shù)據(jù)解析xml
//請(qǐng)求統(tǒng)一下單接口
wx.request({
url: "/tupian/20230522/unifiedorder",
method: 'POST',
data: formData,
success: function (data) {
wx.request({
url: "http://localhost:8080/XinXingWXApi/wxXcxApi/xmlAnalyze.do?strXml=" + data.data,
method: 'POST',
success: function (res) {
var pk = 'prepay_id=' + res.data.prepayId;
var timeStamp = self.createTimeStamp();
//獲取支付簽名，并支付
self.getsignType(appid, timeStamp, nonce_str, pk, "MD5", key);
}
})
}
})
}
});
}第三就是調(diào)用支付了,這里也有幾個(gè)小坑，第一就是appId很多寫成appid就不行了，第二個(gè)就是preoatid 的參數(shù)格式要寫對(duì)prepay_id=wx2017011711060194dccf725232155886323 第三個(gè)就是調(diào)用支付的時(shí)候報(bào)支付簽名錯(cuò)誤，也需要到簽名接口查看簽名是否一致，查看參數(shù)是否是對(duì)的，調(diào)用微信支付的時(shí)候必須加上appId
getsignType: function (appid, timeStamp, nonce_str, pk, signType, key) {
var that = this;
wx.request({
url: "http://localhost:8080/XinXingWXApi/wxXcxApi/getSignType.hn",
method: 'GET',
data: {
appId: appid,
timeStamp: timeStamp,
nonceStr: nonce_str,
pk: pk,
signType: signType,
key: key
},
success: function (res) {
console.log(res.data.paySign)
var paySign = res.data.paySign
//調(diào)用微信支付
wx.requestPayment({
'appId': appid,
'timeStamp': timeStamp,
'nonceStr': nonce_str,
'package': pk,
'signType': 'MD5',
'paySign': paySign,
'success': function (res) {
console.log(res);
console.log('success');
},
'fail': function (res) {
console.log(res);
console.log('fail');
},
'complete': function (res) {
// console.log(res);
console.log('complete');
}
});
}
})
