java - Spring RestTemplate handle custom status code -

-



i should call service application can return unusual http status codes, such 230, 240 etc. default error handler i'm getting:

servlet.service() servlet [dispatcher] in context path [] threw exception [request processing failed; nested exception org.springframework.web.client.unknownhttpstatuscodeexception: unknown status code [230] null] root cause...

when use custom error handler can avoid this:

@override     public boolean haserror(clienthttpresponse response) throws ioexception {          int status = response.getrawstatuscode();         if (status >= 200 && status <= 299)             return false;          httpstatus statuscode = response.getstatuscode();         if (statuscode.is2xxsuccessful())             return false;         httpstatus.series series = statuscode.series();         return (httpstatus.series.client_error.equals(series)                 || httpstatus.series.server_error.equals(series));     }

but when resttmplate tries retrieve falls same exception in messagebodyclienthttpresponsewrapper:

public boolean hasmessagebody() throws ioexception {         httpstatus responsestatus = this.getstatuscode();         if (responsestatus.is1xxinformational() || responsestatus == httpstatus.no_content ||                 responsestatus == httpstatus.not_modified) {             return false;         }         else if (this.getheaders().getcontentlength() == 0) {             return false;         }         return true;     }

how can response body correctly?

i have many .npy (numpy) , .json files saved in s3, need download , load these files. for json files downloading files , loading dictionary using following code: obj = s3.object(bucket, key) response = obj.get() body = response['body'].read().decode('utf-8') data = json.loads(body) that way avoid writing .json file disk , reading it. now want same .npy files, equivalent? currently downloading file, saving temp file on disk , loading np.load avoid if possible. following https://stackoverflow.com/a/28196540/3509999 : obj = s3.object(bucket, key) io.bytesio(obj.get()["body"].read()) f: # rewind file f.seek(0) arr = np.load(f) wiki
