报错：UnicodeDecodeError: ‘utf-8’ codec can’t decode byte 0x89 in position 0: invalid start byte 解决办法

from fastapi import FastAPI,Response
import uvicorn
app=FastAPI()

@app.get("/{path}")
def index(path):
    print(path)
    with open(f"WebServer_html/{path}","r",encoding="UTF-8") as f:
        content = f.read()
        return Response(content=content)
        
uvicorn.run(app,host="192.168.82.163",port=9999)

运行后出错：

更改成gbk格式也不行

from fastapi import FastAPI,Response
import uvicorn
app=FastAPI()

@app.get("/{path}")
def index(path):
    print(path)
    with open(f"WebServer_html/{path}","r",encoding="GBK") as f:
        content = f.read()
        return Response(content=content)
        
uvicorn.run(app,host="192.168.82.163",port=9999)

我试了网上的各种方法：包括如下

1. 在代码前加上两行，实操不行

#-*- coding : utf-8-*-
# coding:utf-8
from fastapi import FastAPI,Response
import uvicorn
app=FastAPI()

@app.get("/{path}")
def index(path):
    print(path)
    with open(f"WebServer_html/{path}","r",encoding="UTF-8") as f:
        content = f.read()
        return Response(content=content)
        
uvicorn.run(app,host="192.168.82.163",port=9999)

2. 用编码格式 “unicode_escape”
   运行确实不出错了，但是运行后中文变成乱码，不行

from fastapi import FastAPI,Response
import uvicorn
app=FastAPI()

@app.get("/{path}")
def index(path):
    print(path)
    with open(f"WebServer_html/{path}","r",encoding="unicode_escape") as f:
        content = f.read()
        return Response(content=content)
        
uvicorn.run(app,host="192.168.82.163",port=9999)

解决办法如下：

# with open(f"WebServer_html/{path}","r",encoding="UTF-8") as f:
with open(f"WebServer_html/{path}","r",encoding="UTF-8",errors='ignore') as f:

在encoding参数后面加上，errors参数并设置为’ignore’。亲测有效
