How to handle context of a processing. #1600
Description
I need to sign the content of body, then add to head.
The signKey is different for each different user.
So i need to pass signKey to SignRequestInterceptor, the signKey is context.
there is context concept in WebClient, can be retrive in any part of the procedue.
q1:
In feign, is there any official way to save the context?
q2:
We could use header as the context, but the defaultRequestHeaders is added as interceptor after the requestInterceptors.
so we can't get the head in requestInterceptors.
Can feign fix it, change the order?
defaultRequestHeaders:
APP_ID: 123
APP_KEY: abc
requestInterceptors:
- club.AuthRequestInterceptor
FeignClientFactoryBean.configureUsingProperties:
if (config.getRequestInterceptors() != null && !config.getRequestInterceptors().isEmpty()) {
// this will add request interceptor to builder, not replace existing
for (Class<RequestInterceptor> bean : config.getRequestInterceptors()) {
RequestInterceptor interceptor = getOrInstantiate(bean);
builder.requestInterceptor(interceptor);
}
}
....
/
addDefaultRequestHeaders(config, builder);
