http的post请求，返回的报文是中文乱码

请求的协议头如下：已经定义了字符集编码是charset=UTF-8;

accept:application/json, text/javascript, */*; q=0.01

accept-language:zh-CN,zh;q=0.9

Content-Type:application/x-www-form-urlencoded;

charset=UTF-8;

cookie: cookie(会自动传入正确的cookie)

已经定义了字符集编码是charset=UTF-8;但是返回的报文的中文部分还是会乱码

尝试 用python请求返回的报文是正常的，为何直接用影刀的http指令请求会乱码？请问大佬们怎么解决呢？
