URL: https://github.com/apache/incubator-shenyu/issues/3025
### Question
In
`org.apache.shenyu.plugin.general.context.GeneralContextPlugin#doExecute`, just
like below:
```java
protected Mono<Void> doExecute(final ServerWebExchange exchange, final
ShenyuPluginChain chain, final SelectorData selector, final RuleData rule) {
Map<String, List<GeneralContextHandle>> generalContextHandleMap =
GeneralContextPluginDataHandler.CACHED_HANDLE.get().obtainHandle(CacheKeyUtils.INST.getKey(rule));
Map<String, Map<String, String>> generalContextMap = new HashMap<>();
HttpHeaders headers = exchange.getRequest().getHeaders();
generalContextHandleMap.forEach((rpcType, v) -> {
if (CollectionUtils.isEmpty(v)) {
return;
}
Map<String, String> generalContextMapWithRpcType = new
HashMap<>();
v.forEach(each -> {
if (StringUtils.isBlank(each.getGeneralContextType()) ||
StringUtils.isBlank(each.getGeneralContextKey())) {
return;
}
switch (each.getGeneralContextType()) {
case Constants.ADD_GENERAL_CONTEXT_TYPE:
generalContextMapWithRpcType.put(each.getGeneralContextKey(),
each.getGeneralContextValue());
break;
case Constants.TRANSMIT_HEADER_TO_GENERAL_CONTEXT_TYPE:
generalContextMapWithRpcType.put(StringUtils.isBlank(each.getGeneralContextValue())
? each.getGeneralContextKey() : each.getGeneralContextValue(),
headers.getFirst(each.getGeneralContextKey()));
break;
default:
break;
}
});
// put the request header from the front end into the
`generalContextMapWithRpcType`
exchange.getRequest().getHeaders().forEach((k, val) ->
generalContextMapWithRpcType.put(k, String.join(", ", val)));
generalContextMap.put(rpcType, generalContextMapWithRpcType);
});
exchange.getAttributes().put(Constants.GENERAL_CONTEXT,
generalContextMap);
return chain.execute(exchange);
}
```
