【报Bug】（接口）发起请求 uni.request 返回结果的header的每个key结尾多出了一个空格

详细问题描述

（接口）发起请求 uni.request 返回结果的header的每个key结尾多出了一个空格

下面是我自己测试的结果：

{"data":{"code":0,"data":{"status":0},"count":null},"statusCode":200,"header":{"Transfer-Encoding ":"chunked","X-Android-Selected-Protocol ":"http/1.1","Strict-Transport-Security ":"max-age=2592000","Server ":"Kestrel","X-Android-Response-Source ":"NETWORK 200","access-token ":"+0c8dCLCrNe+hAQ17AAAtkl6Z1EqJyoVZN+WYTbrwdNiaaa4d96CdUZI+R32HGa/","X-Android-Sent-Millis ":"1555727645822","X-Android-Received-Millis ":"1555727647220","Date ":"Sat, 20 Apr 2019 02:34:07 GMT","Content-Type ":"application/json; charset=utf-8"},"errMsg":"request:ok"}

为了严谨，我给百度首页 https://www.baidu.com 也发了个请求，返回了如下结果（内容太多只截取了部分），也有个空格，所以确定是uni框架的问题
