87.浏览器作为http客户端，不同的浏览器的具体实现机制是不完全相同的。
88.测试分类：
物理机测试(本机测试)，虚拟机测试(跨机测试)，外网阿里云测试(跨域测试)
89.采用std::string并高频使用会降低程序性能。采用c风格字符串的程序
执行效率更高。在高频使用std::string位置应该采用c风格字符串进行
优化。低频使用位置可以不做处理。std::string内部封装的new/delete操作。
90.测试分析：ubuntu虚拟机局域网测试；阿里云外网测试。
91.性能优化分析：找到待优化程序的性能瓶颈，针对瓶颈进行有效性能优化，
才会有效果。
92.性能优化点分析：[HttpClient::std::map<std::string, char*> _headerMap;]
高频通信，比如每秒几千条消息，或者数十万条消息的吞吐量时，每一次采用这个std::
string, 内部都会自动执行new/delete过程，这个过程很消耗系统性能，是程序性能的
瓶颈，应该优化为char*，固定一段内存，避免new/delete创建和销毁对象的系统消耗。

到错误位置。
