The debugger caught an exception in your WSGI application. You can now look at the traceback which led to the error.
To switch between the interactive traceback and the plaintext one, you can click on the "Traceback" headline. From the text traceback you can also create a paste of it. For code execution mouse-over the frame you want to debug and click on the console icon on the right side.

You can execute arbitrary Python code in the stack frames and there are some extra helpers available for introspection:

dump() shows all variables in the frame
dump(obj) dumps all that's known about the object

#返回json
@app.route('/diskio', methods=['POST','GET'])
def disk_io():
    if request.method == 'GET':
        data = diskIO.get_io()
        print data
        return json.dumps(data)   #返回json
    elif request.method == 'POST':
        pass

正常数据出来了:
