flask request.json命令

我得到的JSON數據提交給我的api（使用Flask構建）端點，我需要將該數據導出爲excel，但問題是一旦我的api收到數據並將其加載到請求中。 json數據的「正文」部分被加密 - 不是以同樣的順序收到它，它完全打破了我的表格標題，更不用說需要的輸出excel格式。flask request.json命令

包括下面我收到我的API

正如我所說的原始JSON數據，一旦這樣每個「體」的「行」內讀入API與request.json數據亂七八糟 - 訂單被打破。它應該和標題中所寫的一樣。

我試圖加載它使用不同的json庫，但結果是相同的，加載的數據不是在相同的順序，因爲它給出。我完全無能爲力，爲什麼它會以這種方式發生，這讓我的生活變得非常困難，因爲我對Python比較陌生。

我應該提到，我無法將鍵匹配到標題列，因爲標題可能比「body」「row」中的鍵少。

舉個例子輸出我可以提供略微不同的「炒版」發佈JSON數據：

{ 
"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" 
    ] 
} 
}

和良好的措施增加了Excel導出代碼：

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字典是無序，和JSON對象一樣。你看到的行爲是正常的。

如果您需要保留排序，不使用dict()，但名單了，而不是元組：

[ 
     ["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]串讀身體dict()值，以便，因爲這已經下令你：

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，我的上帝，我覺得不正確讀取蟒蛇真的很傻字典文件:(我現在要做壽，感謝很多的瘋狂快速響應最終我！因爲我無法控制發佈到API的內容，所以停留在第二個版本。 –

我還沒有測試過，但這個答案可能對您有所幫助http://stackoverflow.com/a/6921760/1154535 – Smoe
