Flask 使用蓝图 出现308

我的代码如下

import json
from flask import Blueprint
import psutil

cpu = Blueprint('cpu',__name__)
@cpu.route('/', methods=['GET'])
def CPU_get():
    #获取CPU信息
    cpu_percent = psutil.cpu_percent(interval=1)
    memory_percent = psutil.virtual_memory().percent
    disk_percent = psutil.disk_usage('/').percent
    data = {'CPUpercent': cpu_percent, 'memorypercent': memory_percent, 'diskpercent': disk_percent}
    postdata = json.dumps(data, sort_keys=True, indent=4, separators=(',', ': '))
    return postdata

用postman调试时总是会出现308

但是出现308后又能成功响应200

一开始没在意，但是后来问题就暴露出来了，用postman传大文件时，有时成功有时失败，后来观察发现响应信息的路由后面多了一个斜杠。

解决方法很简单，去掉斜杠就行

import json
from flask import Blueprint
import psutil

cpu = Blueprint('cpu',__name__)
@cpu.route('', methods=['GET'])#去掉此处斜杠
def CPU_get():
    #获取CPU信息
    cpu_percent = psutil.cpu_percent(interval=1)
    memory_percent = psutil.virtual_memory().percent
    disk_percent = psutil.disk_usage('/').percent
    data = {'CPUpercent': cpu_percent, 'memorypercent': memory_percent, 'diskpercent': disk_percent}
    postdata = json.dumps(data, sort_keys=True, indent=4, separators=(',', ': '))
    return postdata
