Question

我使用内置MZFayeClient使用WebSocket（https://github.com/m1entus/MZFayeClient）。我需要实现长轮询技术。怎么做？从哪儿开始？没有关于如何做到这一点的信息（或足够的信息），或者是否有一个带有长轮询的Faye库。

Answer 1

我不是IOS开发人员，但我的一个项目是帮助我的IOS团队整合Faye服务器。

在我的应用程序中，我们有一个已在rails框架上运行的faye-server用于发送通知，然后我们决定使用相同的faye-server向IOS设备发送通知。

IOS团队只需遵循：https://github.com/pcrawfor/FayeObjC

的指示

self.client = [[MZFayeClient alloc] initWithURL:[NSURL URLWithString:@"ws://198.128.0.1:9292/faye"]];

ws://198.128.0.1:9292/faye // this URL is same which is used on web-app.

subscribeToChannel＆amp;其他方法与我们在web-app上使用的方法相同。

Rails应用程序的简单Faye设置。

How can I push to Faye Server from Rails Controller?

它对我有用，我希望也能帮到你..

抱歉我的英语不好;）

1。 Server up and running:

sudo rackup faye.ru -E production -s thin启动Faye服务器

Thin web server (v1.6.4 codename Gob Bluth) Maximum connections set to
1024 Listening on localhost:9292, CTRL+C to stop

检查服务器是否正常工作

curl http://localhost:9292/faye -d 'message={"channel":"/server", "data":"hello"}'

响应

[{"channel":"/server","successful":true}]

服务器日志：

[Faye::RackAdapter] Received message via HTTP POST:
"{\"channel\":\"/server\", \"data\":\"hello\"}" [Faye::Server]
Processing messages: [{"channel":"/server","data":"hello"}] (local:
false) [Faye::Server] Passing through incoming extensions:
{"channel":"/server","data":"hello"} [Faye::Server] Handling message:
{"channel":"/server","data":"hello"} (local: false)
[Faye::Engine::Proxy] Publishing message
{"channel":"/server","data":"hello"} [Faye::Server] Processing reply:
{"channel":"/server","successful":true} [Faye::Server] Passing through
outgoing extensions: {"channel":"/server","successful":true}
[Faye::Server] Returning replies:
[{"channel":"/server","successful":true}] [Faye::RackAdapter] HTTP
response: "[{\"channel\":\"/server\",\"successful\":true}]"

<强> 2。与客户合作：下载MZFayeClient

cd FayeObjC-master/examples
pod install
open FayeObjC.xcworkspace

MZViewController.m

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.client = [[MZFayeClient alloc] initWithURL:[NSURL URLWithString:@"http://localhost:9292/faye"]];
    [self.client subscribeToChannel:@"/server" success:^{
        NSLog(@"ok");
    } failure:^(NSError *error) {
        NSLog(@"Server %@",error);
    } receivedMessage:^(NSDictionary *message) {
        NSLog(@"Server %@",message);
    }];

    self.client.delegate = self;
}

第3。构建示例： 触摸连接：
