- 函数指针
- 使用类作为回调类,然后在类里面定义回调函数
- lambda
- 仿函数
- functional类型
这些都行
from cpphttpdemo.
有的,看55行和110行
先判断是否url然后判断post类型,接受前端参数然后handle

嗯 我在 http_server 看到了代码 。但是有个问题。 我想在 AddHandler 的对象里面编写。但是发现 AddHandler 里面没有
http_message *http_req
这个参数,所以就只能写在http_server的文件里面了。
from cpphttpdemo.
简单,把AddHandler做成回调函数对象,把http_message作为回调参数传出来,就可以handle了,需要一点编程的小技巧

一般真正用在项目中的代码不是想这个demo这么写的,都是用回调
用回调函数把需要的参数和网络连接句柄传入传出,就可以把http通信组件和业务逻辑分割

好的 我去试试~大佬能提供2-3行的代码一个小示例吗?感激不尽 我这里C++这一块不太熟悉……
from cpphttpdemo.
// sth like this
void HttpServer::HandleHttpEvent(mg_connection *connection, http_message *http_req, Callback callback)
{
// use callback to handle the request
callback(connection, http_req);
}
// write your callback outside
typedef void(mg_connection *connection, http_message *http_req) Callback;
// pass the this callback function to the http event handle function as function pointer
void MyCallback(mg_connection *connection, http_message *http_req)
{
// check http_req
// use connection to send response
}

ok 另外还有个问题 就是 用 SendHttpRsp(connection, buffer.GetString()) 返回json的时候 中文会乱码。但是 在debug中 看 buffer 的是正常的
内存中的查看结果:
{
"userInfo": {
"wxid": "asdfadsfasdf",
"userName": "阿拉拉了",
"lalalal": "你好啊"
}
cout 结果也正常
{
"userInfo": {
"wxid": "asdfadsfasdf",
"userName": "阿拉拉了",
"lalalal": "你好啊"
}
}
但是 postman 接受的 返回json却编码不正常
{ "result": {
"userInfo": {
"wxid": "asdfadsfasdf",
"userName": "��������",
"lalalal": "����ү"
}
} }
不知道怎么回事
from cpphttpdemo.
这样写 也不行:
SendHttpRsp(connection, "错误方法");
结果是这个:
{ "result": ���� }
from cpphttpdemo.
问题也定位了 就是 mongoose 这里的代码问题 但是我不知道怎么解决:
//mg_printf_http_chunk(connection, "{ \"result\": %s }", rsp.c_str());
mg_printf_http_chunk(connection, rsp.c_str());
from cpphttpdemo.
需要中文转码
试试这个,不是gbk就是utf8

搞定 谢谢啦 windows 加一个 gbktoutf8 即可

啊 post 的cilent 有么有示例?我想写一个发送的客户端~
