Question

这是我的服务器代码

var srv = https.createServer(credentials, app);
var ioRoot = socket.listen(srv);
var ioDev = ioRoot.of('/dev');
srv.listen(5014);
ioRoot.set('transports', ['polling'])
ioRoot.use(function(socket, next){
    console.log("CONSOLE.LOG SOCKET.HANDSHAKE", socket.handshake);
    next(true);
})
ioRoot.on('connection', function(ss){

    console.log('ioRoot')
    ss.emit('connect', {
        success: true
    })
})
ioDev.on('connection', function(ss){
    console.log('ioDev')
    ss.emit('connect', {
        success: true
    })
})

这是我的目标-c代码

NSURL* url = [[NSURL alloc] initWithString:@"MY URL"];
    SocketIOClient* socket = [[SocketIOClient alloc] initWithSocketURL:url config:@{@"log": @YES, @"secure": @YES, @"connectParams":@{@"testing":@"YEEEEE"}}];

    [socket on:@"connect" callback:^(NSArray* data, SocketAckEmitter* ack) {
        NSLog(@"socket connected");
    }];

    [socket on:@"testRoot" callback:^(NSArray* data, SocketAckEmitter* ack) {
        NSLog(@"testRoot");
    }];

    [socket on:@"testNsp" callback:^(NSArray* data, SocketAckEmitter* ack) {
        NSLog(@"testRoot");
    }];

    [socket on:@"disconnect" callback:^(NSArray* data, SocketAckEmitter* ack) {
        NSLog(@"testRoot dc");
    }];
    [socket on:@"error" callback:^(NSArray* data, SocketAckEmitter* ack) {
        NSLog(@"testRoot err");
    }];
    [socket on:@"reconnect" callback:^(NSArray* data, SocketAckEmitter* ack) {
        NSLog(@"testRoot rc");
    }];
    [socket on:@"reconnectAttempt" callback:^(NSArray* data, SocketAckEmitter* ack) {
        NSLog(@"testRoot rc at");
    }];
    [socket on:@"open" callback:^(NSArray* data, SocketAckEmitter* ack) {
        NSLog(@"testRoot open");
    }];
    [socket on:@"message" callback:^(NSArray* data, SocketAckEmitter* ack) {
        NSLog(@"testRoot message");
    }];
    [socket onAny:^(SocketAnyEvent* event){
        NSLog(@"!!! GOT AN EVENT %@",event);
    }];

    [socket connect];

因此，据我所知，节点js正在发送消息并期待一些响应，并且ios没有响应，因此节点js因超时而关闭客户端。但是在ios Log上我没有看到任何相关内容。

要写这个作为答案，但只是推测：

我认为你的套接字是dealloc：

在.m文件的顶部添加

@interface CLASS_NAME ()

@property (strong, nonatomic) SocketIOClient *socket;

@end

然后改变：

SocketIOClient* socket = [[SocketIOClient alloc] initWithSocketURL:url config:@{@"log": @YES, @"secure": @YES, @"connectParams":@{@"testing":@"YEEEEE"}}];

到：

self.socket = [[SocketIOClient alloc] initWithSocketURL:url config:@{@"log": @YES, @"secure": @YES, @"connectParams":@{@"testing":@"YEEEEE"}}];

ios上的套接字IO不会过去握手
