默认的情况luasocket TCP的函数receive()可以收到在末尾加入’\n’的数据，换一种接收方式receive(‘*a’)却收不到数据，服务端发送的数据在末尾不加入’\n’ 一样也收不到，这是为何呢?
请问楼主解决了吗
我断点可以看到c++有数据,但lua却拿不到？
将cocos2d-x\external\lua\luasocket\buffer.c
下的recvraw 和 recvall修改成下面这样，重新编译后搞定
/-------------------------------------------------------------------------\
- Reads a fixed number of bytes (buffered)
*-------------------------------------------------------------------------*/
static int recvraw(p_buffer buf, size_t wanted, luaL_Buffer *b) {
int err = IO_DONE;
size_t total = 0;
while (err == IO_DONE) {
size_t count; const char *data;
err = buffer_get(buf, &data, &count);
//没有接收到数据，跳出循环
if (count == 0) {
if(total > 0 && err == IO_TIMEOUT){
return IO_DONE;
}
break;
}
count = MIN(count, wanted - total);
luaL_addlstring(b, data, count);
buffer_skip(buf, count);
total += count;
if (total >= wanted) break;
}
return err;
}
/-------------------------------------------------------------------------\
- Reads everything until the connection is closed (buffered)
*-------------------------------------------------------------------------*/
static int recvall(p_buffer buf, luaL_Buffer *b) {
int err = IO_DONE;
size_t total = 0;
while (err == IO_DONE) {
const char *data; size_t count;
err = buffer_get(buf, &data, &count);
//没有接收到数据，跳出循环
if (count == 0) {
if(total > 0 && err == IO_TIMEOUT){
return IO_DONE;
}
break;
}
total += count;
luaL_addlstring(b, data, count);
buffer_skip(buf, count);
}
if (err == IO_CLOSED) {
if (total > 0) return IO_DONE;
else return IO_CLOSED;
} else return err;
}
