Open Feign Client Use JSON String (with curly braces) as Header - openfeign

Question

I tried to set this JSON string to a header for open feign client
**apiheader**={"digitalSignature": "digitalSignature", "timeoutTime": "0", "headerVersion": "1.0", "correlation": { "requestId": "0e34c7cf-1fc5-457d-9593-646edba4d3d8", "myId": "T0TPart042715545524b4-fef5-4b97-86e0-f738bddec8c2", "myTimeStamp": "2017-03-30T15:41:04.575-04:00", "callPath": "GetData", "keyValues": " " }, "who": { "employeeUserId": "TEST12", "partyMultiFactorAuthenticationIndicator": "WERTY" } }
But feign client cut it off to soemthing like this in log, this will cause invalid header. Can anyone help on this case? Looks like feign client treat the JSON string as an expression rather than a normal header.
---> POST https://sit1.hostname.net:6007/GetData HTTP/1.1
**apiheader: {"digitalSignature": "digitalSignature", "timeoutTime"}**
Content-Length: 283
Content-Type: application/json
**Below is the Feign client interface:**
#FeignClient(name = "postFeignClient", url = "https://sit1.hostname.net:6007/", configuration = {FeignClientsConfiguration.class, SSLFeignClientConfig.class})
public interface GetDataApi {
#PostMapping(value="/GetData")
#Headers({
"Content-type: application/json; charset=utf-8",
"Accepts: application/json",
"apiheader: {apiheader}"
})
GetDataResponse getData(
#RequestHeader(value="apiheader") String apiheader,
GetDataRequest body);
}
FeignClient Configuration
#Configuration
public class SSLFeignClientConfig {
#Bean
#Scope("prototype")
#ConditionalOnMissingBean
public Feign.Builder feignBuilder() {
Client client;
Optional<SSLSocketFactoryConfig> socketFactory = SSLContextSocketFactory.loadSocketFactoryConfig();
try {
SSLContext context = SSLContextSocketFactory.loadSSLContext();
client = new Client.Default(context.getSocketFactory(), new NoopHostnameVerifier());
} catch (Exception e) {
logger.error("Create feign client with SSL config failed", e);
client = new Client.Default(null, null);
}
return Feign.builder().client(client);
}
}
Controller:
#Autowired
GetDataApi getDataApi;
#GetMapping(value="/test")
public GetDataResponse getData() throws IOException {
GetDataResponse response;
GetDataRequest request=new GetDataRequest();
String apiheader="{\"digitalSignature\": \"digitalSignature\", \"timeoutTime\": \"0\", \"headerVersion\": \"1.0\", \"correlation\": { \"requestId\": \"0e34c7cf-1fc5-457d-9593-646edba4d3d8\", \"myId\": \"T0TPart042715545524b4-fef5-4b97-86e0-f738bddec8c2\", \"myTimeStamp\": \"2017-03-30T15:41:04.575-04:00\", \"callPath\": \"GetData\", \"keyValues\": \" \" }, \"who\": { \"employeeUserId\": \"TEST12\", \"partyMultiFactorAuthenticationIndicator\": \"WERTY\" }, \"what\": { \"API\": \"GetData\", \"APIFunction\": \"Submit\", \"keyValues\": \" \" }, \"where\": { \"originatorLocationId\": \"111\", \"originatorLocationType\": \"OnLine\", \"originatorApplicationCatalogueId\": \"111\", \"originatorChannel\": \"CC\", \"originatorSessionId\": \"632587415\", \"keyValues\": \" \" }}";
response=getDataApi.getData(apiheader, request);
return response;
