通过websocket将web3连接到使用nginx的节点时出现问题
我们正在尝试通过WebSocket连接到geth节点,以便能够订阅合同事件。这个节点是用docker创建的,这个docker使用nginx作为代理 我们可以轻松地使用http(而不是WS-rpc)进行连接,但无法使用http订阅契约事件 我们已经成功地在docker映像的本地实例中与具有相同nginx代理的nodejs websocket服务器建立了连接。但是我们无法连接web3 v1.0.0-beta55 我们得到的两个不同错误是403(禁止)与此nginx配置(这是一个适用于非web3 websockets的配置): 或此其他配置出现错误400(错误请求):通过websocket将web3连接到使用nginx的节点时出现问题,nginx,websocket,blockchain,solidity,web3,Nginx,Websocket,Blockchain,Solidity,Web3,我们正在尝试通过WebSocket连接到geth节点,以便能够订阅合同事件。这个节点是用docker创建的,这个docker使用nginx作为代理 我们可以轻松地使用http(而不是WS-rpc)进行连接,但无法使用http订阅契约事件 我们已经成功地在docker映像的本地实例中与具有相同nginx代理的nodejs websocket服务器建立了连接。但是我们无法连接web3 v1.0.0-beta55 我们得到的两个不同错误是403(禁止)与此nginx配置(这是一个适用于非web3 we

在客户端,我们可以
Error during WebSocket handshake: Unexpected response code: 400||403
或
现在,我们正在跟踪此docker映像的本地实例中可能存在的端口问题,但是我们已经多次配置节点通过已经在工作的http rpc端口接收此ws连接(显然,将所有geth和nginx配置更改为接收wsrpc而不是http rpc),并且我们得到了相同的错误代码
我们的主要猜测是nginx没有正确地传递WebSocket请求。我们询问了仲裁网络技术团队,他们从未尝试建立WebSocket连接,他们不知道如何进一步帮助我们。任何猜测都很受欢迎
谢谢
