Python flask request.json订单

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将其加载到“body”部分数据被打乱了-与我收到数据的顺序不同，这完全打破了我的表格标题，更不用说所需的输出excel格式了

下面是我接收到的原始JSON数据

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

正如我所说的，一旦使用request.json将其读入api，“body”的每个“行”中的数据都被置乱——顺序被打破。它应该写在标题中

我尝试使用不同的json库加载它，但结果是一样的，加载的数据顺序与给定的顺序不同。我完全不知道为什么会这样，这让我的生活变得非常困难，因为我对Python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“body”行中的键少

作为示例输出，我可以提供稍微不同的发布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)

r=request.json
data=r['data']
如果数据：
#初始化excel导出
excel=工作簿（）
工作表=excel。添加工作表（“报告”）
##Excel标题
#设置字体样式
font=font（）
font.name='Arial'
font.bold=True
#设置单元格边框样式
边框=边框（）
borders.bottom=1
borders.right=1
#设置格式化样式
style=XFStyle（）
style.font=font
style.borders=边框
#写标题
header=数据['header'][0]
headers=header.split（“，”）
h=0
对于标题中的列：
如果col==“false”：
col=''
书写（0，h，col，style）
h+=1
#正文
行=数据['body']
i=1
对于行中的行：
x=第页第（i）行
y=0
对于键，第行中的值。iteritems（）
x、 写入（y，值）
y+=1
i+=1
#写页脚
页脚=数据['footer'][0]
footers=footer.split（'，'）
f=0
对于页脚中的列：
如果col==“false”：
col=''
书写（i、f、col）
f+=1
#设置列宽
如果h>f：
cols=h
其他：
cols=f
a=0
而a

Python字典和JSON对象都是无序的。你看到的行为是正常的

如果需要保留顺序，请不要使用

dict（）

，而是使用元组列表：

   [
       ["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，因为已经为您排序了：

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

哦，我的天，我觉得没有正确阅读pythons dict文档真的很愚蠢：（现在我读了tho，非常感谢您的快速响应！最后我坚持使用第二个版本，因为我无法控制发布到API的内容。我还没有测试它，但这个答案可能对您有所帮助
