如何将请求的JSON消息转换为可用数据? [英] How do I convert a requested JSON message to usable data?

问题描述

我有一个烧瓶服务器正在运行，当我手动访问127.0.0.1:5000/data/get_data时，它会向我提供JSON消息. 在此flask服务器中，CORS被禁用，并且在我的提取请求中，我还添加了{mode: 'no-cors'}.

每当我在javascript中使用fetch-request时，响应都为空，而Flask告诉我听到了GET请求，并发送了响应. 当我手动请求数据时，Flask会给我完全相同的输出(并且我可以在浏览器中查看接收到的JSON).

I have a flask server running that provides me with a JSON message when I manually visit 127.0.0.1:5000/data/get_data. CORS is disabled in this flask server and in my fetch-request I added {mode: 'no-cors'} as well.

Whenever I use the fetch-request in javascript, the response is empty while Flask tells me the GET request was heard and a response was sent. Flask gives me the exact same output when I manually request the data (and I can view the received JSON in the browser).

这是执行提取请求的javascript代码

This is the javascript code to do the fetch-request

fetch('http://127.0.0.1:5000/data/get_data', {
    mode: 'no-cors'
})
.then(response => console.log(response));

FLASK清楚地获得了请求并发送了响应:

FLASK clearly gets the request and sends a response:

FETCH请求收到的内容(登录到firefox开发者控制台)

我很想知道如何接收flask发送的数据，并将其保存在javascript字典中.

what the FETCH-request receives (logged in firefox dev-console)

I would love to know how I can receive the data that flask sends out, and keep it in a dictionary in javascript.

推荐答案

fetch('http://127.0.0.1:5000/data/get_data', {
    mode: 'no-cors'
})
.then(response => response.json())
.then(json => console.log(json));
