解决python3 requests headers参数不能有中文的问题

1 需求，heeaders 参数需要拼接中文参数param 解决如下

url = 'https://....search?keyword=' + param + '&templateId=&page=1&pageSize=10'
headers = {
"Accept": "application/json, text/javascript, */*; q=0.01",
"Accept-Encoding": "gzip, deflate, br",
"Accept-Language": "zh-CN,zh;q=0.9",
"Connection": "keep-alive",
"Cookie": "Hm_lvt_0076fef7e919d8d7b24383dc8f1c852a=1522398473; Hm_lpvt_0076fef7e919d8d7b24383dc8f1c852a=1522398482",
"Referer": "https://...../index.html?index=0&keyword=" + urllib.parse.quote(param),
"User-Agent": "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3202.94 Safari/537.36",
"X-Requested-With": "XMLHttpRequest"
}
rsp = requests.get(url, headers=header

from urllib import parse

str1 = 'haha哈哈'
str2 = parse.quote(str1)  #quote()将字符串进行编码
print(str2)        #str2=haha％E5％93％88％E5％93％88
str3 = parse.unquote(str2) #解码字符串
print(str3)        #str3=haha哈哈
