Socket.io-client: 无法通过 react-native 上的 socket.io-client 连接

Looks like this is react-native's issue.看起来这是 react-native 的问题。 Earlier versions of RN seem to work with socket.io, but 0.0.57 does not.早期版本的 RN 似乎可以与 socket.io 一起使用，但 0.0.57 不能。 Closing.关闭。

Try "socket.io-client": "2.0.4"尝试“socket.io-client”：“2.0.4”
This may be socket.io bug这可能是 socket.io 错误

Try "socket.io-client": "2.0.4"尝试“socket.io-client”：“2.0.4”
This may be socket.io bug这可能是 socket.io 错误

Yes it does work.是的，它确实有效。

使用 RN 0.52 和 socket.io-client 2.0.4 我仍然面临这个问题。

@noahprince22 can you please share your configuration ? @noahprince22你能分享你的配置吗？
I am currently using this and the issue still persist.我目前正在使用这个，问题仍然存在。

"react-native": "0.55.4",
"react": "16.3.1",
"socket.io-client": "^2.0.4",
"socket.io: "^2.2.0" //server side

any workaround?任何解决方法？

socket.io team please, this should work with RN, is a socket.io bug. socket.io 团队请，这应该适用于 RN，是一个 socket.io 错误。

Hi @ningacoding , I managed to get it working with this configuration嗨@ningacoding ，我设法让它与这个配置一起工作

"react-native": "0.55.4",
"react": "16.3.1",
"socket.io-client": "^2.0.4",
"socket.io: "^1.0.0" //server side

In your react-native app use this在你的 react-native 应用程序中使用这个

const socket = io(BASE_URL, {
    secure: true,
    transports: ['websocket'],
  });

"react-native": "0.58.6", “反应原生”：“0.58.6”，
"react": "16.6.3", “反应”：“16.6.3”，
"socket.io-client": "^2.0.4", "socket.io-client": "^2.0.4",

Not working for me不为我工作

any solution?任何解决方案？ I'm facing the same thing我面临同样的事情

I have long since stopped working on the project that I was having this issue with.我早就停止了我遇到这个问题的项目。 If I remember correctly, I downgraded react-native to "solve' the problem.如果我没记错的话，我将 react-native 降级为“解决”问题。

Experiencing the same issue, has there been a fix yet?遇到同样的问题，请问有解决了吗？ Anyone find any workarounds to implementing sockets in React Native?有人找到在 React Native 中实现套接字的任何解决方法吗？

@russellgoldman I had problems with RN 0.60.5 and socket.io. @russellgoldman我在使用 RN 0.60.5 和 socket.io 时遇到了问题。 Release build did not connect to the server.发布版本未连接到服务器。

None of socket.io versions worked with RN 0.60.5: I tried versions 2.0.4, 2.1.1, 2.2.0.没有一个 socket.io 版本适用于 RN 0.60.5：我尝试了 2.0.4、2.1.1、2.2.0 版本。

Downgrading to RN 0.59.10 solved my problem.降级到 RN 0.59.10 解决了我的问题。

Hi @anttirauh and @russellgoldman ,嗨@anttirauh和@russellgoldman ，
I tried with RN 0.59.10 and Socket 2.0.4, but its not connecting on release build.我尝试使用 RN 0.59.10 和 Socket 2.0.4，但它在发布版本时没有连接。
Can you please help me?你能帮我么？

@Ramesh21071993我认为您必须将 socket.io 升级到 2.1.1 版本。

@anttirauh , i tried with all these versions socket io (2.0.4, 2.1.1, 2.2.0) and react-native versions (0.60, 0.59.10, 0.59.4) @anttirauh ，我尝试了所有这些版本的套接字 io（2.0.4、2.1.1、2.2.0）和 react-native 版本（0.60、0.59.10、0.59.4）
In server side also socket io 2.0.4.在服务器端还有socket io 2.0.4。
still that same issue sir,还是同样的问题，先生，

But it works on RN 0.55.4但它适用于 RN 0.55.4

@Ramesh21071993 My understanding (which is formed with heavy googling and own testing) is that: @Ramesh21071993我的理解（通过大量的谷歌搜索和自己的测试形成）是：

• socket.io stopped working with react-native about around RN version 0.57.4 socket.io 在 RN 版本 0.57.4 左右停止使用 react-native
• socket.io or some other component was fixed later and I managed to get it working with version combo: RN 0.59.10 + socket.io 2.1.1 socket.io 或其他一些组件后来被修复，我设法让它与版本组合一起工作：RN 0.59.10 + socket.io 2.1.1
• RN version 0.60.x is not working with any version of socket.io RN 版本 0.60.x 不适用于任何版本的 socket.io

So my advice is only: try one time more with RN 0.59.10 and socket.io 2.1.1 and make sure that you clear build folder before building.所以我的建议只是：用 RN 0.59.10 和 socket.io 2.1.1 再试一次，并确保在构建之前清除构建文件夹。 And remove node_modules before yarn/npm.并在 yarn/npm 之前删除 node_modules。

@anttirauh Sir, below is my package.json. @anttirauh先生，下面是我的 package.json。 I did as what you told.我照你说的做了。 But nothing happen.但什么也没有发生。 I remove build folder and node modules and again i install.我删除了构建文件夹和节点模块，然后再次安装。
Please help me on this to work, Past one month am trying请帮我解决这个问题，过去一个月我正在尝试

Finally found a solution for React Native >= 0.60 after a couple of coffees and digging deep into engine.io - additional to a version conflict (with RN) there seems to be an issue with passing in the URI.在喝了几杯咖啡并深入研究 engine.io 之后，终于找到了 React Native >= 0.60 的解决方案——除了版本冲突（与 RN）之外，传递 URI 似乎存在问题。 When I pass an URI into socketIO, it gets turncated to the host and 'socket.io' appened.当我将 URI 传递给 socketIO 时，它会被转接到主机并附加“socket.io”。 So socketIO("https://foo.bar/my/endpoint/socket.io") will lead to socketIO trying to connect to https://foo.bar/socket.io without showing it in the logs when throwing the xhr pull / socket error.所以socketIO("https://foo.bar/my/endpoint/socket.io")将导致 socketIO 在抛出 xhr pull / socket 错误时尝试连接到https://foo.bar/socket.io而不在日志中显示它。

Here we go, how to get socket.io running on current versions of React Native :我们开始吧，如何让 socket.io 在当前版本的 React Native 上运行：

• use socket.io-client version _2.1.1_使用socket.io-client版本_2.1.1_

// package.json
{
  "dependencies": {
     "socket.io-client": "2.1.1"
   }
}

• when setting up the client, define a host and a path设置客户端时，定义主机和路径

const socket = socketIO('https://your.host.com/', {
  path: '/path/to/socket.io/'
})

• and suddenly everything works as smooth as planed突然间一切都像计划的一样顺利

Hope to have saved you the time I spent on this issue 😆希望可以节省我花在这个问题上的时间😆

@rastapasta , i got an error like “ CLEARTEXT communication not permitted by network security policy ”, @rastapasta ，我收到类似“网络安全策略不允许 CLEARTEXT 通信”之类的错误，

Please tell me what to do请告诉我应该怎么做

@Ramesh21071993 if you can't use your endpoint via https (please consider it), add their hostnames to the exception lists. @Ramesh21071993如果您无法通过 https 使用您的端点（请考虑），请将其主机名添加到例外列表中。

Sir, I tried that also but not able to do.先生，我也尝试过，但无法做到。 If you don't mind can you please give me any demo source files如果您不介意，请给我任何演示源文件
For long time I struck with this.很长一段时间我都对此感到震惊。

Am using ip and port sir我正在使用 ip 和端口先生

遵循上述文档的指示并调整此实现：

import socketIO from 'socket.io-client'
const socket = socketIO('http://8.8.8.8:3000/', {
  path: '/your/path/to/socket.io/'
  reconnectionDelay: 1000,
  reconnection: true,
  reconnectionAttempts: Infinity,
  jsonp: false
})

socket.on('connect', () => console.log('connected'))
socket.on('error', console.error)
socket.on('connect_error', console.error)

先生，在服务器端我正在使用socket io 2.1.1，可以吗？或者有什么需要改变的吗

@Lizhooh在 rn 上找出 whazzup 的黑客方法：在node_modules engine.io-client/blob/master/lib/transports/中的self.onError console.log(err)打补丁轮询-xhr.js #L131

@Ramesh21071993 Is your issue resolved? @Ramesh21071993你的问题解决了吗？ I am facing the same issue.我面临同样的问题。 Tried everything mentioned in above comments.尝试了上述评论中提到的所有内容。

@rastapasta I followed what you have suggested above. @rastapasta我遵循了您上面的建议。 My socket connection happens and then immediately disconnects.我的套接字连接发生，然后立即断开连接。 I get timeout error infinitely.我无限地收到超时错误。 However, whenever I click on some component which makes a network call, the socket connects and immediately disconnects.但是，每当我单击某个进行网络调用的组件时，套接字都会连接并立即断开连接。 If I don't do any network call after first socket disconnect, it would stay in the same state.如果我在第一次套接字断开连接后不进行任何网络调用，它将保持相同的状态。 Please, could you help?请问，你能帮忙吗？

socket = io('http://IP:31515', { socket = io('http://IP:31515', {
path: '/socketio', //I have given this is the path in my socket server as well as my kubernetes ingress file to route to that port path: '/socketio', //我已经给出了这是我的套接字服务器中的路径以及我的 kubernetes 入口文件以路由到该端口
transports: ['websocket'],传输：['websocket']，
reconnectionDelay: 1000,重新连接延迟：1000，
reconnection: true,重新连接：真，
reconnectionAttempts: Infinity,重新连接尝试：无限，
// timeout: 30000, // 超时：30000，
jsonp: false jsonp：假
}); });

things that I have tried:我尝试过的事情：

1. removing and adding transports option删除和添加传输选项
   2.removing and add timeout 2.删除和添加超时
2. removing all parameters except path删除除路径之外的所有参数
3. adding pingTimeout and pingInterval in server socket configuration在服务器套接字配置中添加 pingTimeout 和 pingInterval
4. removing path from server and client and only keeping it in my kubernetes ingress file to route to that deployment/pod.从服务器和客户端删除路径，仅将其保存在我的 kubernetes 入口文件中以路由到该部署/pod。

Note: the same server and kubernetes conf work for any node.js socket client as well as my react js web app.注意：相同的服务器和 kubernetes conf 适用于任何 node.js 套接字客户端以及我的 react js web 应用程序。 I am only facing this issue for React Native app in debug as well as release mode.我只在调试和发布模式下遇到 React Native 应用程序的这个问题。

有人对我的上述问题有任何想法吗？

Please make sure to请确保

• add your host to the transport exception list (s. here )将您的主机添加到传输例外列表（此处）
• try it without manually defining the transports在不手动定义传输的情况下尝试
• monkey patch the console.log (s. here ) and check the error猴子修补console.log（在这里）并检查错误

Can anyone please share a complete working example for both client and server?任何人都可以为客户端和服务器分享一个完整的工作示例吗？ Because this is confusing.因为这很混乱。
