我将 JSON 数据提交到我的 api（使用 Flask 构建）端点，我需要将该数据导出到 excel，但问题是一旦我的 api 接收到数据并使用request.json加载它，数据的“正文”部分被打乱了 - 与我收到它的顺序不同，这完全破坏了我的表格标题，更不用说所需的输出 excel 格式了。

包括以下我收到到我的 api 的原始 JSON 数据

{

    "header": [
        "date,group.groupname,user.NameSurname,forwarding_number,reciver_number,CallerNameSurname,alert,connection,call_summ"

正如我所说，一旦使用request.json将其读入 api ，“body”的每个“行”中的数据就会被打乱 - 顺序被破坏。它应该如标题中所写。

我尝试使用不同的 json 库加载它，但结果是相同的，加载的数据与给出的顺序不同。我完全不知道为什么会发生这种情况，这让我的生活变得非常困难，因为我对 Python 还比较陌生。

我应该提到，我无法将键与标题列匹配，因为标题的键可能比“正文”“行”中的键少。

作为示例输出，我可以提供稍微不同的已发布 JSON 数据的“加扰版本”：

{
"data": {
    "body": [
        {
            "group.groupname": "customerService",
            "connection": "00:01:28",
            "call_summ": "00:01:42",
            "CallerNameSurname": "false",
            "forwarding_number": "66055002",
            "user.NameSurname": "Arnolds Apels",
            "date": "2012-12-13",
            "reciver_number": "66055002",
            "alert": "00:00:14"
        },
        {
            "group.groupname": "customerService",
            "connection": "00:01:33",
            "call_summ": "00:01:45",
            "CallerNameSurname": "false",
            "forwarding_number": "66055002",
            "user.NameSurname": "Arnolds Apels",
            "date": "2012-12-13",
            "reciver_number": "66055002",
            "alert": "00:00:12"
        },
        {
            "group.groupname": "administration",
            "connection": "00:00:30",
            "call_summ": "00:00:33",
            "CallerNameSurname": "false",
            "forwarding_number": "67783165",
            "user.NameSurname": "Ieva Sproģe",
            "date": "2012-12-13",
            "reciver_number": "67783165",
            "alert": "00:00:03"
        }
    ],
    "header": [
        "date,group.groupname,user.NameSurname,forwarding_number,reciver_number,CallerNameSurname,alert,connection,call_summ"
    ],
    "footer": [
        "false,false,user.NameSurname,forwarding_number,reciver_number,CallerNameSurname,alert,connection,call_summ"
    ],
    "filename": [
        "asdasda.xls"
    ]
}
}

为了更好地衡量添加 excel 导出代码：

r = request.json
data = r['data']
if data:
    # Initialize excel export
    excel = Workbook()
    sheet = excel.add_sheet('Report')

    ## Excel headers

    # Setup font styling
    font = Font()
    font.name = 'Arial'
    font.bold = True

    # Setup cell border styling
    borders = Borders()
    borders.bottom = 1
    borders.right = 1

    # Setup formating style
    style = XFStyle()
    style.font = font
    style.borders = borders

    # Write headers
    header = data['header'][0]
    headers = header.split(',')
    h = 0
    for col in headers:
        if col == 'false':
            col = ''
        sheet.write(0, h, col, style)
        h += 1

    # Write body
    rows = data['body']
    i = 1
    for row in rows:
        x = sheet.row(i)
        y = 0
        for key, value in row.iteritems():
            x.write(y, value)
            y += 1
        i += 1

    # Write footer
    footer = data['footer'][0]
    footers = footer.split(',')
    f = 0
    for col in footers:
        if col == 'false':
            col = ''
        sheet.write(i, f, col)
        f += 1

    # Setup column widths
    if h > f:
        cols = h
    else:
        cols = f
    a = 0
    while a < cols:
        sheet.col(a).width = 5000
        a += 1

    # Get report filename
    filename = data['filename'][0]

    # Setup report path
    path = "/path/to/exports/" + filename

    # Save the report
    excel.save(path)

Python 字典是无序的，JSON 对象也是如此。你看到的行为是正常的。

如果您需要保留顺序，请不要使用 a dict()but a list up tuples 代替：

   [
       ["date", "2013-01-08"],
       ["group.groupname", "customerService"],
       ["user.NameSurname", "Romāns Tiščenko"],
       ["forwarding_number", "66055002"],
       ["reciver_number", "66055002"],
       ["CallerNameSurname", false],
       ["alert", "00:00:14"],
       ["connection", "00:00:53"],
       ["call_summ", "00:01:07"]
   ],
   # ... etc.

或者您也可以使用data['header'][0]字符串按顺序读取正文dict()值，因为这已经为您订购了：

rows = data['body']
i = 1
for row in rows:
    x = sheet.row(i)
    y = 0
    for col in headers:
        x.write(y, row.get(col, ''))
        y += 1
    i += 1
