You can also set debug: console.log in the connection config objects to get debug output, although you may want to use a custo m function for each connection so you can differentiate output for each connection (e.g. debug: function(s) { console.log('srcServer: ' + s); } for the srcServer connection config Try enabling debug output and see what is being sent and what the server is replying with when the error occurs. 平时都是到处console.log(xxxx)来判断，昨天收到了这句话，但是不知道该如何使用 debug: console.log这个方法啊，这个方法调试的时候能显示what is being sent and what the server is replying? 我用的是webstorm IDE

等会i5ting就会来推荐vs code了
var yourFunction = function () {};
yourFunction.prototype.debug = function(s){
console.log('srcServer'+s)
}
我觉得是这个意思，在server上加一个debug函数，跟IDE没啥关系
@CarlosRen 这种打log的调试还是有点low，哈哈
@CarlosRen 恩恩，学到了
@hellopao 哈哈，老司机
异步的我喜欢console.. 顺便vscode调试杠杠的
webstorm 有点重不喜欢。nodejs项目用vscode（因为调试很方便），其他用sublime。
