使用Ajax、jQuery将数据发布到Django
使用Ajax、jQuery将数据发布到Django
提问于 2018-06-08 00:32:20
我想提交html5地理位置数据到django管理后端。但是，我不确定index.html javascript中的javascript、jQuery和ajax设置是否正确。我能够在html页面中显示纬度和经度，但无法将数据发布到django。有没有好心的人帮我纠正我可能犯错的地方。作为一个新手，我已经花了一周的时间来研究它。都会真心感谢任何帮助。谢谢。
到目前为止工作的代码如下所示。django应用的文件结构如下：
-ajax
- __pycache__
- migrations
- __pycache__
0001_initial.py
__init__.py
- static
- css
- bootstrap.css
- fonts
- js
- script.js
- templates
- ajax
- base.html
- index.html
- __init__.py
- admin.py
- apps.py
- models.py
- tests.py
- urls.py
- views.py
-server
- __pycache__
- __init__.py
- settings.py
- urls.py
- views.py
- wsgi.py
-db.sqlite3
-manage.pyindex.html
{% extends 'ajax/base.html' %}
{% block body %}
<p>Click the button to get your coordinates.</p>
<button onclick="getLocation()">Get Your Location</button>
<p id="demo"></p>
<button type="button" id="btn_submit" class="btn btn-primary form-control" disabled>Submit</button>
{% endblock %}script.js
var pos;
var $demo;
function getLocation() {
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(showPosition);
} else {
$demo.text("Geolocation is not supported by this browser.");
}
}
function showPosition(position) {
pos = position;
var { latitude, longitude } = pos.coords;
$demo.html(`Latitude: ${latitude}<br>Longitude: ${longitude}`);
$('#btn_submit').attr("disabled", null);
}
$(document).ready(function() {
$demo = $("#demo");
$('#btn_submit').on('click', function() {
var data = pos.coords;
data.csrfmiddlewaretoken = $('input[name=csrfmiddlewaretoken]').val();
$.post("/echo/html/", data, function() {
alert("Saved Data!");
});
});
});base.html

最可能的原因是因为模板中没有CSRF令牌标记。
您必须将其放入模板中，如下所示：
{% csrf_token %}您还可以定义视图不需要将装饰器csrf_exempt放入CSRF令牌：
from django.views.decorators.csrf import csrf_exempt
@csrf_exempt
def my_view(request):
return HttpResponse('Hello world')希望能对你有所帮助！
