我正在处理将数据发布到服务器的Django应用程序。
以下是Python代码段:
def save(request):
if request.method != 'POST':
return HttpResponse('Illegal Request')
print(request.POST.get('dataObj'))
return JsonResponse({'status':200})
客户端的JQuery:
function submitQuoationClicked()
{
dataObj = getQuotationInJSON()
console.log(dataObj)
token = $("input[name=csrfmiddlewaretoken]").val()
$.ajax({
type:"POST",
url:"/quotations/save",
data: {
'csrfmiddlewaretoken': token,
'dataObj' : dataObj,
},
success: function(data){
if(data.status === 200)
console.log("Good Work Falak!") //TODO Remove this line, FOR DEBUGGING ONLY
}
});
function getQuotationInJSON()
{
var data = {};
data['title'] = $("#title").val()
data['companyName'] = $("#company").val()
data['addressLine1'] = $("#addressLine1").val()
data['addressLine2'] = $("#addressLine2").val()
data['city'] = $("#city").val()
data['country'] = $("#country").val()
data['date'] = $("#date").val()
data['number'] = $("#number").val()
data['validTill'] = $("#validTill").val()
sections = getItemsData();
data['sections'] = sections
return data
}
function getItemsData()
{
sections = []
$("tr[id^='section']").each(function(index, element)
{
sectionId = $(element).attr('id').split('section')[1]
name = $(element).find("#sectionName" + sectionId).val()
section = {}
section['name'] = name
//Now get section items
rowElems = $(".section" + sectionId)
rows = []
$(rowElems).each(function(index, row){
if($(row).attr('id').indexOf('itemRow')>=0)
{
description = $(row).find("#description").val()
quantity = $(row).find("#quantity").val()
unitPrice = $(row).find("#unitPrice").val()
margin = $(row).find("#margin").val()
if(quantity!="" && unitPrice!="" && description!="" && margin!="")
{
row = {}
row['description'] = description
row['quantity'] = quantity
row['unitPrice'] = unitPrice
row['margin'] = margin
rows.push(row)
}
}
});
section['items'] = rows;
sections.push(section)
});
return sections
}
JSON对象是一个引用,其中包含一些基本细节。它有一些部分,每个部分都有一个名称和该部分中的项目列表。每个项目都有一些属性。但打印(request.body)返回'无'。如果我打印(request.body),它会打印以下文本:
B' csrfmiddlewaretoken = ph8NQTz5uDtYaTSI5bDVAcdQ0MQtPrYWMMpIFOYP5eqD8urd2wtPRtxypBSnNg1J&安培; dataObj%5Btitle%5D =标题&安培; dataObj%5BaddressLine1%5D =安培; dataObj%5BaddressLine2%5D =安培; dataObj%5Bcity%5D =安培; dataObj%5Bcountry%5D =安培; dataObj%5Bdate%5D =安培; dataObj%5Bnumber%5D =安培; dataObj%5BvalidTill%5D =安培; dataObj%5Bsections%5D%5B0%5D%5Bname%5D = S1&安培; dataObj%5Bsections%5D%5B0%5D %5Bitems%5D%5B0%5D%5Bdescription%5D =嘿&安培; dataObj%5Bsections%5D%5B0%5D%5Bitems%5D%5B0%5D%5Bquantity%5D = 2及dataObj%5Bsections%5D%5B0%5D%5Bitems %5D%5B0%5D%5BunitPrice%5D = 9&安培; dataObj%5Bsections%5D%5B0%5D%5Bitems%5D%5B0%5D%5Bmargin%5D = 0'
我试图获得dataObj'来自request.POST.get(' dataObj),但它返回None。
导致问题的原因是什么?
答案 0 :(得分:0)
在使用Ajax发出POST请求时,请在请求中添加以下标头:
ContentType:application/x-www-form-urlencoded
答案 1 :(得分:0)
POST中的密钥将如下所示:request.POST.get('dataObj[title]')
有关如何在request.body中处理JSON的详细信息,请参阅此问题的答案 Where's my JSON data in my incoming Django request?
答案 2 :(得分:0)
我已经找到了问题所在。我试图传递的对象是Javascript对象,而不是JSON。所以键出现的不是预期的格式。所以,我不得不使用JSON.stringify()
方法。
这是更新的代码: // Ajax调用修改为:
$.post("/quotations/save", {csrfmiddlewaretoken: token,
data: JSON.stringify(dataObj)}, //Edited here
function(result){
if(result.status===200){
console.log("Good Work Falak!")
}
else
{
console.log("Failed!")
}
});
