[Day27] 第二十七章-建立订单api (nodejs)

前言

我们目前把laravel的服务都写得差不多了
後来发现没有实际测试过订单建立
这边我们来把订单api补完吧!

目标

1. 回去把nodejs api补完
2. 包装成建立订单function

实作

1. 前置条件(要送的参数跟url)

参数如下列json

要送的url(method是POST)

https://apisbx.sinopac.com/funBIZ/QPay.WebAPI/api/Order

这些是要送的json参数

{
    "Version": "1.0.0",
    "ShopNo": "NA0XXXXXX",
    "APIService": "OrderCreate",
    "Sign": "CD7925BFC65EA32016262708BF0C35E396EFF8A7988DA6BACD51F0404AA30C88",
    "Nonce": "NjM3Njk2NzkxMDM2NzMuNjo1MTYwY2Q5OGZhZDA3ODg1Njg4NzNjMTI4NmRjOWJmNmNiODA1MzE5ZGI0NWNlNDBkZWE5MDRlMmQ4MjUyMjYy",
    "Message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
"
}

2. 重新包装function

"Version": "1.0.0",
"ShopNo": "NA0XXXXXX",
"APIService": "OrderCreate",

上方这三个参数是固定值我们就不需要改过了

最後我们重新call nonce

async function callnonce() {
  return axios
    .post("https://apisbx.sinopac.com/funBIZ/QPay.WebAPI/api/Nonce", {
      ShopNo: "NA0249_001",
    })
    .then((res) => {
      return res.data.Nonce;
    });
}

接下来是sign值

//重新排列物件顺序 这边是使用lodash
function sign(my_object) {
  var result = _.omitBy(
    my_object,
    (v) => _.isUndefined(v) || _.isNull(v) || v === ""
  );

  var resultkeys = _.without(_.keys(result), "").sort();
  var hashstring = resultkeys.reduce((acc, cur, idx) => {
    if (idx == resultkeys.length - 1) {
      return acc + `${cur}=${result[cur]}`;
    }
    return acc + `${cur}=${result[cur]}&`;
  }, "");
  return hashstring;
}

//最後要加密的sign值
function getsign(nonce) {
  // console.log(req.body);
  // var result = sign(req.body);
  var result = sign(msg);
  const hashrr = result + nonce + hashid;
  const hashresult = sha256(result + nonce + hashid);
  return hashresult.toLocaleUpperCase();
}

接者是加密的function

function decmessage(nonce) {
  const IV = sha256(nonce).substr(-16, 16).toLocaleUpperCase();
  const cipher = createCipheriv("aes-256-cbc", hashid, IV);
  let encrypted = cipher.update(msg, "utf8", "hex");
  encrypted += cipher.final("hex");
  const result = encrypted.toLocaleUpperCase();
  console.log(encrypted);

  return result;
}

3. 建立订单api

app.post("/createOrder", async function (req, res) {
  const Version = "1.0.0";
  const ShopNo = "NA0249_001";
  const APIService = "OrderCreate";
  const Nonce = await callnonce();
  const signData = getsign(Nonce);
  const Message = decmessage(Nonce);
  return axios
    .post("https://apisbx.sinopac.com/funBIZ/QPay.WebAPI/api/Order", {
      Version,
      ShopNo,
      APIService,
      Sign: signData,
      Nonce,
      Message,
    })
    .then(({ data }) => {
      return res.send(data);
    });
});

我们把上面function重新包装後再打api到永丰去
最後来验证成果吧!

总结

我们的时间越来越少了
接下来会是者把laravel call nodejs的api串完
再把结帐纪录储存!!完结我们的project吧!!
