充值訂單 換算成美元 方法，利用bootstrap-table插件和requests庫實現

效果圖：

前端js代碼：

// 訂單彙總 請求
$(document).ready(function () {
    $('#orderSumBtn').click(function () {
        if ( !$('#rechargeStartTime').val() || !$('#rechargeEndTime').val() ) {
            alert('充值時間不能爲空！');

        } else {
            createOrderSumTable();
        }
    })
});

// 訂單彙總 查詢結果返回  調用 bootstrap-table 插件
function createOrderSumTable() {
    $('#order_sum').bootstrapTable('destroy');
    postOrderSumData = function () {
        var temp = {
            "zoneID": $('#zoneID').val(),
            "channelID": $('#channelID').val(),
            "payType": $('#payType').val(),
            "orderState": $('#orderState').val(),
            "country": $('#country').val(),
            "currency": $('#currency').val(),
            "gameOrderId": $('#gameOrder').val(),
            "channelOrder": $('#channelOrder').val(),
            "UID": $('#UID').val(),
            "rechargeStartMoney": $('#rechargeStartMoney').val(),
            "rechargeEndMoney": $('#rechargeEndMoney').val(),
            "rechargeStartTime": $('#rechargeStartTime').val(),
            "rechargeEndTime": $('#rechargeEndTime').val(),
            "inAccountStartTime": $('#inAccountStartTime').val(),
            "inAccountEndTime": $('#inAccountEndTime').val()
        };
        return temp;
    };
    $('#order_sum').bootstrapTable({
        url: '/orderSum',
        method: 'post',
        contentType:"application/x-www-form-urlencoded; charset=UTF-8",
        queryParams: postOrderSumData,
        cache: false,
        pagination: true,
        sidePageination: 'client',  // 注意：我這裏是 客戶端分頁！！
        pageNumber: 1,
        pageSize: 20,
        pageList: [10, 25, 50],
        height: 420,
        silent: true,    // 刷新服務器數據
        rowStyle: function (row, index) {  // 設置最後一行 行樣式
            if (index == $('#order_sum').bootstrapTable('getData').length-1) {
                return {
                    css: {
                        "text-align": "center"
                    }
                };
            }
            return {};
        },
        columns: [{
            field: 'fromCurrency',
            title: '充值貨幣',
            valign: 'middle',
            // align: 'left',
            // halign: 'center'
        }, {
            field: 'rechargePlayersCount',
            title: '充值人數（去重）',
            valign: 'middle'
        }, {
            field: 'rechargeOrders',
            title: '充值訂單數量',
            valign: 'middle'
        }, {
            field: 'fromCurrencyAmount',
            title: '充值貨幣數量',
            valign: 'middle'
        }, {
            field: 'rate',
            title: '匯率',
            valign: 'middle'
        }, {
            field: 'toUSDAmount',
            title: '美元',
            valign: 'middle'
        }],
        responseHandler: function (res) {
            var orderSumData = res['rows'];
            return orderSumData;
        },
        onLoadSuccess: function (data) {
            var index = $('#order_sum').bootstrapTable('getData').length-1;
            $('#order_sum').bootstrapTable('mergeCells', {index: index, field: 'rechargePlayersCount', colspan: 5});   // 合併單元格，只能 從 左 向 右 合併
        }
    })
}

後端python接受並處理請求：

def order_sum(request):
    postOrderSumData = request.POST
    requestResults = requestsOrderSum(postOrderSumData)   ### 發送到 model層，處理具體請求
    if requestResults == 0:
        return HttpResponse('0')

    elif requestResults == -1:
        return HttpResponse('-1')
    else:
        returnData = {"rows": []}
        totalUSD = 0   ### 美金 累加計算
        for result in requestResults:
            totalUSD += float(result['toUSDAmount'])
            returnData['rows'].append({
                "fromCurrency": result['fromCurrency'],
                "rechargePlayersCount": result['rechargePlayersCount'],
                "rechargeOrders": result['rechargeOrders'],
                "fromCurrencyAmount": result['fromCurrencyAmount'],
                "rate": result['rate'],
                "toUSDAmount": result['toUSDAmount']
            })
''' 將 最終 美元的數據結果，放到 去重人數 那一列，可以合併單元格（左 --> 右）    %.2f float保留2位小數 '''
        returnData['rows'].append({"fromCurrency": "美元總計", "rechargePlayersCount": '%.2f' % totalUSD})
    return HttpResponse(json.dumps(returnData))

後端model層處理具體請求：

def requestsOrderSum(postOrderSumData):
    queryResult = db_queryOrder(postOrderSumData)  ### 先去 數據庫中，查詢符合條件的 數據
    if queryResult == 0:
        return 0
    elif queryResult == -1:
        return -1
    else:
        ''' 當 有查詢結果時，才執行下面的彙總，以及發起 匯率請求 '''
        currencyData = []     #彙總結果，如：[{'USD': '555'}]
        queriedCurrency = []  #記錄 已經查詢過的 貨幣
        j = -1  #第2個循環的 計數器
        for data in queryResult:
            j += 1
            fromCurrency = data['pricecurrencycode']  # 本地貨幣
            fromCurrencyAmount = data['priceamount']  # 本地貨幣金額
            rechargePlayers = data['uid']             # 充值玩家（UID識別）
            rechargePlayersCount = 1                  # 充值人數計數（去重）
            rechargeOrders = 1                        # 充值訂單數
            #print('j======= ', j)
            if fromCurrency not in queriedCurrency:  # 只有不在 queriedCurrency 裏的，纔可以 進行循環 彙總求和
                    rechargePlayersSet = set()  # Set集合，需要 集合中的元素不能有重複的（每筆訂單的充值客戶UID）
                ''' 雙循環 '''
                for i in range(j+1, len(queryResult)): ## 注意這裏，是 j+1 ！！！！！
                    #print(i)  # 0-310
                    if fromCurrency == queryResult[i]['pricecurrencycode']:
                        fromCurrencyAmount += queryResult[i]['priceamount']   # 充值金額 彙總
                        rechargeOrders += 1                                   # 充值訂單數 彙總
                        rechargePlayersSet.add(queryResult[i]['uid'])         # 向Set中 添加元素
                ''' 去重人數計算，遍歷Set集合 '''
                for player in rechargePlayersSet:
                    if rechargePlayers != player:
                        rechargePlayersCount += 1                            # 充值人數計數（去重）彙總
                queriedCurrency.append(fromCurrency)
                currencyData.append({"fromCurrency": fromCurrency, "fromCurrencyAmount": fromCurrencyAmount, "rechargePlayersCount": rechargePlayersCount, "rechargeOrders": rechargeOrders})
        # print(currencyData)
        return requestUSD(currencyData)  ## 發起 爬蟲請求

後端requests爬蟲：

import requests
import re

def requestUSD(currencyData):
    requestResults = []    ## 收集 爬蟲結果集
    for requestData in currencyData:
        getParams = {'from': requestData['fromCurrency'], 'to': 'USD', 'q': requestData['fromCurrencyAmount']}
        r = requests.get('http://m.ip138.com/huilv/huilv.asp', params=getParams)
        if r.status_code == 200:
            r.encoding = 'utf-8'   # 設定編碼，否則會出現 亂碼
            content = r.text
            #print(content)
            data=content.split('<table border="1" cellpadding="3" cellspacing="0" width="260" align="left"><tr align=center>')[1]
            #print(data)
            result = re.match('<td>([^<]*)</td><td>[^<]*</td><td>[^<]*</td></tr>\s*<tr align=center><td>([^<]*)</td><td>([^<]*)</td><td>([^<]*)</td>', data)
            #print('匹配結果：', result.group())
            fromCurrency = result.group(1) #獲取 第1個 捕獲組
            fromCurrencyAmount = result.group(2)
            rate = result.group(3)
            toUSDAmount = result.group(4)
            #print(fromCurrency, fromCurrencyAmount, rate, toUSDAmount)
            requestResults.append({"fromCurrency": fromCurrency, "fromCurrencyAmount": fromCurrencyAmount, "rate": rate, "toUSDAmount": toUSDAmount, "rechargePlayersCount": requestData['rechargePlayersCount'], "rechargeOrders": requestData['rechargeOrders']})
    #print(requestResults)
    return requestResults
