使用AJAX从Bottlepy服务器获取数据

Question

I'm trying to retrieve json data from a bottlepy server onto a webpage. 我正在尝试将瓶状服务器中的json数据检索到网页上。 I was trying to implement a basic version first so tried with just strings. 我尝试首先实现基本版本，因此仅使用字符串尝试过。 But nothing seems to be happening. 但是似乎什么也没发生。 Here is the code - 这是代码-

HTML(including js) - HTML（包括js）-

<!DOCTYPE>
<html>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>

<body>
<script>
function print()
{
    $(document).ready(function(){
        $.get('http://localhost:8080/check', function(result){
            alert('success');
            $('#main').html(result);
        });
    });
}

print();
</script></body>
</html>

The python code - python代码-

from bottle import Bottle, route, get,request, response, run, template

app = Bottle()

@app.hook('after_request')
def enable_cors():
    response.headers['Access-Control-Allow-Origin'] = '*'

# a simple json test main page
str = "Hello"
@route('/')                   #irrelevant to this question. Used this to check server...
def test():
    return template('file', str)

@app.get('/check')
def showAll():
    return str

run(host='localhost', port=8080)

What do I have to do to access the data on the server? 我需要做什么才能访问服务器上的数据？ Note : The HTML is a separate file, and I want the code to work irrespective of the location of the HTML. 注意：HTML是一个单独的文件，并且无论HTML的位置如何，我都希望代码能够工作。

Also, if this is not possible, how can I do it with the help of templates? 另外，如果这不可能，我如何借助模板来做到这一点？

Your problem stems from some confusion with the bottle app. 您的问题源于与Bottle应用程序有些混淆。

Bottle creates a default app for you whenever you use @route (more on this) , and reuses this default app implicitly on subsequent calls. 每当您使用@route时，Bottle都会为您创建一个默认应用程序（有关更多信息），并在后续调用中隐式重用此默认应用程序。 This default app behavior is present in many functions (including hook and run ). 许多功能（包括hook和run ）中都存在此默认应用行为。

The point is: 重点是：

app = Bottle() # creates an explicit app

@route('/')    # adds the route to the default app

@app.hook('after-request')  # adds the hook to the explicit app

run(...) # runs the default app, the hook is not used

To solve your problem you have two options: 要解决您的问题，您有两种选择：

remove any mention of the explicit app; 删除任何提及显式应用程序的内容；
always use the app explicitly 始终明确使用该应用

I found using the app explicitly made it easier to create sub-apps and much more clear in general what was going on. 我发现使用该应用程序显式地使得创建子应用程序更加容易，并且总体上更清楚了发生了什么。

New code: 新代码：

import bottle
from bottle import response, template, run

app = bottle.Bottle()

@app.hook('after_request')
def enable_cors():
    response.headers['Access-Control-Allow-Origin'] = '*'

# a simple json test main page
str = "Hello"
@app.route('/')                   #irrelevant to this question. Used this to check server...
def test():
    return template('file', str)

@app.get('/check')
def showAll():
    return str

run(app=app, host='localhost', port=8080)
