Flask使用蓝图出现308

我的代码如下

import json
from flask import Blueprint
import psutilcpu &＃61; Blueprint(&＃39;cpu&＃39;,__name__)
&＃64;cpu.route(&＃39;/&＃39;, methods&＃61;[&＃39;GET&＃39;])
def CPU_get():#获取CPU信息cpu_percent &＃61; psutil.cpu_percent(interval&＃61;1)memory_percent &＃61; psutil.virtual_memory().percentdisk_percent &＃61; psutil.disk_usage(&＃39;/&＃39;).percentdata &＃61; {&＃39;CPUpercent&＃39;: cpu_percent, &＃39;memorypercent&＃39;: memory_percent, &＃39;diskpercent&＃39;: disk_percent}postdata &＃61; json.dumps(data, sort_keys&＃61;True, indent&＃61;4, separators&＃61;(&＃39;,&＃39;, &＃39;: &＃39;))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&＃xff0c;但是后来问题就暴露出来了&＃xff0c;用postman传大文件时&＃xff0c;有时成功有时失败&＃xff0c;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&＃xff0c;去掉斜杠就行

import json
from flask import Blueprint
import psutilcpu &＃61; Blueprint(&＃39;cpu&＃39;,__name__)
&＃64;cpu.route(&＃39;&＃39;, methods&＃61;[&＃39;GET&＃39;])#去掉此处斜杠
def CPU_get():#获取CPU信息cpu_percent &＃61; psutil.cpu_percent(interval&＃61;1)memory_percent &＃61; psutil.virtual_memory().percentdisk_percent &＃61; psutil.disk_usage(&＃39;/&＃39;).percentdata &＃61; {&＃39;CPUpercent&＃39;: cpu_percent, &＃39;memorypercent&＃39;: memory_percent, &＃39;diskpercent&＃39;: disk_percent}postdata &＃61; json.dumps(data, sort_keys&＃61;True, indent&＃61;4, separators&＃61;(&＃39;,&＃39;, &＃39;: &＃39;))return postdata
