Bug Fixed: Content-Type在包含charset时无法正确解析

[Aaron-QL]

当header中的Content-Type包含charset时，content-type被存储为application/json; charset=utf-8，这会导致body中的数据body中的数据无法正常解析。

我的请求参数

curl -X "POST" "http://127.0.0.1:18306/user/register" \
     -H 'foo: bar' \
     -H 'Content-Type: application/json; charset=utf-8' \
     -d $'{
  "name": "akaQin",
  "pwd": "abcdefg",
  "age": "18"
}'

我遇到的报错
