SpringBoot對接微信小程序支付功能開發(fā)（一，下單功能）

2年前作者：慶登登登分類：Toy博客閱讀(31)違法舉報

這篇具有很好參考價值的文章主要介紹了SpringBoot對接微信小程序支付功能開發(fā)（一，下單功能）。希望對大家有所幫助。如果存在錯誤或未考慮完全的地方，請大家不吝賜教，您也可以點擊"舉報違法"按鈕提交疑問。

1，接入前準(zhǔn)備：

  1. 接入模式選擇直連模式；
  2. 申請小程序，得到APPID，并開通微信支付；
  3. 申請微信商戶號，得到mchid，并綁定APPID；
  4. 配置商戶API key，下載并配置商戶證書，根據(jù)微信官方文檔操作：https://pay.weixin.qq.com/wiki/doc/apiv3/open/pay/chapter2_8_1.shtml
  5. 上面都配置完之后會得到：小程序APPID、商戶號mchid、商戶證書序列號、API_V3密鑰、商戶私鑰。

2，代碼開發(fā)

引入微信支付API v3依賴

        <!--微信支付依賴 v3版本-->
        <dependency>
            <groupId>com.github.wechatpay-apiv3</groupId>
            <artifactId>wechatpay-apache-httpclient</artifactId>
            <version>0.2.2</version>
        </dependency>

微信參數(shù)常量類：WechatPayConstant 參數(shù)自行更換

下單接口調(diào)用

下單功能實現(xiàn)，返回預(yù)支付交易會話標(biāo)識prepay_id

    @Override
    public CommonResult submitOrder() throws Exception {
        // 小程序下單
        CloseableHttpClient httpClient = WxPayUtil.getHttpClient();
        HttpPost httpPost = new HttpPost(WechatPayConstant.V3_JSAPI_URL);
        httpPost.addHeader("Accept", "application/json");
        httpPost.addHeader("Content-type", "application/json; charset=utf-8");

        ByteArrayOutputStream bos = new ByteArrayOutputStream();
        ObjectMapper objectMapper = new ObjectMapper();

        ObjectNode rootNode = objectMapper.createObjectNode();
        rootNode.put("mchid", WechatPayConstant.MCH_ID)
                .put("appid", WechatPayConstant.MP_APP_ID)
                .put("notify_url", WechatPayConstant.NOTIFY_URL)
                .put("description", "商品描述信息")
                .put("out_trade_no", System.currentTimeMillis() + "");
        rootNode.putObject("amount")
                .put("total", 100);// 訂單支付金額
        rootNode.putObject("payer")
                .put("openid", "小程序用戶openid");
        objectMapper.writeValue(bos, rootNode);

        httpPost.setEntity(new StringEntity(bos.toString("UTF-8"), "UTF-8"));
        //完成簽名并執(zhí)行請求
        CloseableHttpResponse response = httpClient.execute(httpPost);
        try {
            int statusCode = response.getStatusLine().getStatusCode();
            if (statusCode == 200) {
                //處理成功返回的數(shù)據(jù)
                String body= EntityUtils.toString(response.getEntity());
                //JSONObject jsonObject = JSON.parseObject(body);
                //獲取預(yù)支付交易會話標(biāo)識  prepay_id
                //String prepayId= jsonObject.getString("prepay_id");
                //把上面的訂單信息存入訂單數(shù)據(jù)庫
                return body;
            } else if (statusCode == 204) {
                // 處理成功，無返回Body
                return "success";
            } else {
                System.out.println("failed,resp code = " + statusCode + ",return body = " + EntityUtils.toString(response.getEntity()));
                throw new IOException("request failed");
            }
        } finally {
            response.close();
        }
    }

到這里代表下單操作完成了。把預(yù)支付交易id（prepay_id）返回前端，進(jìn)行拉起支付操作

        int statusCode = response.getStatusLine().getStatusCode();
        log.info("關(guān)閉訂單返回碼：{}", statusCode);
        if (statusCode == 204) {
            return "關(guān)單成功";
        }
        return "關(guān)單失敗";
    }
