django使⽤Ajax⽅式POSTJSON数据包
⽰例1：jquery实现ajax
js:
function SaveAction(){
//点击保存按键
var senddata = {"type":"A", "host":"www", "resolution_line":"0", "data":"172.16.2.3", "mx":"5", "ttl":"600"}
$.ajax({
url: "/dns/add.html",
type: "POST",        //请求类型
data: {"data":senddata},
dataType: "json",  // 这⾥指定了 dateType 为json后，服务端响应的内容为json.dumps(date)，下⾯ succe
ss 的callback 数据⽆需进⾏JSON.parse(callback)，已经是⼀个对象了，如果没有指定dateType则需要执⾏ JSON.parse(callback)        success: function (callback) {
//当请求执⾏完成后，⾃动调⽤
//callback, 服务器返回的数据
console.log(callback);
},
error: function () {
//当请求错误之后，⾃动调⽤
}
});
}
django 后台 view:
def record_add(req):
"""
添加解析记录
:param req:
:return:
"""
hod == 'POST':
type = ('data[type]')
host = ('data[host]')
resolution_line = ('data[resolution_line]')
data = ('data[data]')
mx = ('data[mx]')
ttl = ('data[ttl]')
print(type, host, resolution_line, data, mx, ttl)
return HttpResponse('hehe')
else:
return HttpResponse('use POST request method please.')
⽰例2：
JS
function SaveAction(){
//点击保存按键
var _type = $(".modal-body select[name=type]").val();
var _host = $(".modal-body input[name=host]").val();
var _resolution_line = $(".modal-body select[name=resolution_line]").val();
var _data = $(".modal-body input[name=data]").val();
var _mx = $(".modal-body input[name=mx]").val();
var _ttl = $(".modal-body select[name=ttl]").val();
var senddata = {"type":_type, "host":_host, "resolution_line":_resolution_line, "data":_data, "mx":_mx, "ttl":_ttl }
$.ajax({
url: "/dns/add.html",
type: "POST",        //请求类型
//contentType: "application/json; charset=utf-8",
data: senddata,
dataType: "json",
success: function (callback) {

//arg, 服务器返回的数据
console.log(callback);
},
error: function () {
//当请求错误之后，⾃动调⽤

});

建议使⽤这种⽅式
js
function SaveAction(){
//点击保存按键
var _type = $(".modal-body select[name=type]").val();
var _host = $(".modal-body input[name=host]").val();
var _resolution_line = $(".modal-body select[name=resolution_line]").val();
var _data = $(".modal-body input[name=data]").val();
var _mx = $(".modal-body input[name=mx]").val();
var _ttl = $(".modal-body select[name=ttl]").val();
var senddata = {"type":_type, "host":_host, "resolution_line":_resolution_line, "data":_data, "mx":_mx, "ttl":_ttl }    $.ajax({
url: "/dns/add.html",
type: "POST",        //请求类型
data: {'data': JSON.stringify(senddata)},
dataType: "json",
success: function (callback) {
//当请求执⾏完成后，⾃动调⽤
//arg, 服务器返回的数据
console.log(callback);
},
error: function () {
//当请求错误之后，⾃动调⽤
}
});
}
