问题描述
我有一个用Java编写的服务器和一个用PHP编写的客户端.如果出现任何问题，客户端如何从服务器捕获异常?在gRPC文档中找不到任何有关异常处理的信息.
I have a server written in Java and client written in PHP. How can client catch exception from server if anything goes wrong? I can't find anything about exception handling in gRPC documentation.
谢谢！
推荐答案
对于已处理的异常，请调用responseObserver.onError().如果传入StatusRuntimeException或StatusException(通常是通过status.asRuntimeException()创建的)，则状态代码和描述将传达给客户端.回调中未处理的异常将取消RPC，并将继续传播异常(通常导致为执行程序调用UncaughtExceptionHandler).
For handled exceptions, call responseObserver.onError(). If you pass in a StatusRuntimeException or StatusException (generally created via status.asRuntimeException()) the status code and description will be communicated to the client. Unhandled exceptions within a callback will cancel the RPC and will continue propagating the exception (generally leading in an UncaughtExceptionHandler being called for the executor).
