问题没有找到，cocos creator 1.7 生产项目有问题吧，我mac 用户是Sjw,没有 /Users/nantas/这个目录呢？
1.7.0以上版本都有问题，socket发送数据不带数据
没看懂。
this.sio.emit(event); 1.7.0以前版本发送数据方式正常，现在这段代码放在1.7.0以后版本会出现上面错误
你这是胡说啊。看1.6中的代码：
bool js_cocos2dx_SocketIO_emit(JSContext* cx, uint32_t argc, JS::Value* vp)
{
CCLOG("JSB SocketIO.emit method called");
JS::CallArgs args = JS::CallArgsFromVp(argc, vp);
JS::RootedObject obj(cx, args.thisv().toObjectOrNull());
js_proxy_t *proxy = jsb_get_js_proxy(cx, obj);
SIOClient* cobj = (SIOClient *)(proxy ? proxy->ptr : NULL);
JSB_PRECONDITION2( cobj, cx, false, "Invalid Native Object");
if (argc == 2) // 看这里，必须要两个参数，如果你只传一个eventname，那么这个逻辑是直接报JSB SocketIO.emit: Wrong number of arguments的
{
std::string eventName;
do
{
bool ok = jsval_to_std_string(cx, args.get(0), &eventName);
JSB_PRECONDITION2( ok, cx, false, "Error processing arguments");
} while (0);
std::string payload;
do {
bool ok = jsval_to_std_string(cx, args.get(1), &payload);
JSB_PRECONDITION2( ok, cx, false, "Error processing arguments");
} while (0);
CCLOG("JSB SocketIO emit event '%s' with payload: %s", eventName.c_str(), payload.c_str());
cobj->emit(eventName, payload);
return true;
}
JS_ReportErrorUTF8(cx, "JSB SocketIO.emit: Wrong number of arguments");
return false;
}
看我上面注释。
不过这的确是个问题。我稍后修复。但这不是1.7引入的问题。是一直以来就有的问题。
这样做，没有问题，只是以前代码要修改下
我晕，1.6中直接把 undefined转换为空字符串了。
理论上不应该是空的，按照js标准，undefined强制转换为字符串，应该是字符串“undefined”的。
bool jsval_to_std_string(JSContext *cx, JS::HandleValue v, std::string* ret) {
if (v.isString())
{
JS::RootedString tmp(cx, v.toString());
JSB_PRECONDITION3(tmp, cx, false, "Error processing arguments");
JSStringWrapper str(tmp);
*ret = str.get();
}
else if (v.isBoolean())
{
*ret = v.toBoolean() ? "true" : "false";
}
else if (v.isInt32())
{
char buff[20];
snprintf(buff, sizeof(buff), "%d", v.toInt32());
*ret = buff;
}
else if (v.isNumber())
{
char buff[20];
snprintf(buff, sizeof(buff), "%.2f", v.toNumber());
*ret = buff;
}
else if (v.isNullOrUndefined())
{
*ret = ""; // 看这里。
}
else
{
return false;
}
return true;
}
我打脸了。
engine仓库居然有这样的代码：
https://github.com/cocos-creator/engine/blob/v1.7-release/jsb/jsb-etc.js#L142
所以c++这层，固定是传递了两个参数，如果没有第二个参数，默认是补上undefined的。
而1.6的jsval_to_std_string 把 undefined转换为“”，这个行为是错误的。
我想想如何处理吧。
不知道楼主还会不会看消息 我在学习大佬的源码但是现在就到创建房间进不去游戏 不知道该怎么办 求指教
