flask-restful 扩展
json 返回中文乱码
背景 https://v2ex.com/t/694457

#通过以下代码已解决中文乱码
api.representations = {'application/json;charset=utf-8': output_json}

新问题

#python 、rust 等测试正常
import requests
res = requests.get(url="http://127.0.0.1:5000/api/v1/login")
print(res.text)
#go 测试异常
resp,_ := http.Get("http://127.0.0.1:5000/api/v1/login")
body,_ :=ioutil.ReadAll(resp.Body)
fmt.Println(string(body))

demo 项目里 requirements.txt 加一下？防止是库版本的问题

Golang 的 http 包发请求时默认不带 header，没有 header 时 flask 默认的 mediatype 是“application/json”, api.representations 里定义的 key 是'application/json;charset=utf-8'，再加一个 key 或者把原来的 key 改成"application/json"就好了

```
api.representations = {'application/json;charset=utf-8': output_json, "application/json": output_json}
```
