django应用程序在读取json文件python时给出404错误
[英]django application giving 404 error while reading json file python
问题描述
Here is the code: 
这是代码：
views.py : views.py ：
@csrf_exempt
def post_list(request):
return render(request, 'blog/post_list.html', {})
@csrf_exempt
def show(request):
return render(request, 'tt/readjson.html', {})
urls.py : urls.py ：
from django.urls import path
from . import views
urlpatterns = [
path('', views.post_list),
path('test/', views.data_return),
path('tt/', views.show),
]
readjson.html : readjson.html ：
<html>
<head>
<script src="https://code.jquery.com/jquery-1.10.2.js"></script>
<script>
$.getJSON("log0.json", function (data) {
$.each(data, function (index, value) {
console.log(value);
});
});
</script>
</head>
<body>
Hello
</body>
</html>
The output I am getting is hello on the screen. 我得到的输出在屏幕上hello 。 But in the console log I see this: 但是在控制台日志中，我看到了：
jquery-1.10.2.js:8706 GET http://127.0.0.1:8000/tt/log0.json 404 (Not Found)
send @ jquery-1.10.2.js:8706
ajax @ jquery-1.10.2.js:8136
jQuery.(anonymous function) @ jquery-1.10.2.js:8282
getJSON @ jquery-1.10.2.js:8265
(anonymous) @ (index):5
jquery-1.10.2.js:8706 XHR failed loading: GET "http://127.0.0.1:8000/tt/log0.json".
The json file is in the same folder where the html template is kept, that is in the tt folder. json文件位于html模板所在的文件夹中，即tt文件夹中。
Please let me know what might I do to avoid the missing part. 请让我知道如何避免丢失零件。

It's no good putting your JSON into the same folder as the template. 将JSON与模板放在同一文件夹中并没有好处。 Templates aren't accessible via HTTP requests; 无法通过HTTP请求访问模板； they are rendered by views served at URLs. 它们由URL提供的视图呈现。
You should put your JSON into a static directory and access it via STATIC_URL; 您应该将JSON放入静态目录，然后通过STATIC_URL访问它； alternatively you could write a view to serve it like you have for your other templates, but there doesn't seem to be any point doing that. 或者，您可以编写一个视图来像其他模板一样为它提供服务，但是这样做似乎没有任何意义。
