java - Camel: keep a file to folder depended on response -


i have dsl this:

            from("file:data/inbox?noop=true")                 .marshal()                 .string("utf-8")                 .setheader(exchange.content_type,constant("application/json"))             .to("http://www.a-service.com")                 .choice()                     .when(new predicate() {                         @override                         public boolean matches(exchange exchange) {                             message in = exchange.getin();                             string msg = in.getbody(string.class);                              system.out.println(" response: " + msg);                              if(msg.contains("\"status\":\"ok\"")){                                 return true;                             }else{                                 return false;                             }                         }                     })                         // ok!!!                         .to("file:data/outbox_success")                     .otherwise()                         // not ok !!!                         .to("file:data/outbox_fail");

i expected if http response has "status":"ok", files go "data/outbox_success". otherwise, go "data/outbox_fail".

but not expected: yes, files has been copied "outbox_xxx" but there no content in files.

i guess because "in" message has been changed http response.

so, how can copy file folder depended on response of 'http' ?

try storing body in header later use:

 from("file:data/inbox?noop=true")             .marshal()             .string("utf-8")             .setheader(exchange.content_type,constant("application/json"))         .setheader("filebody", simple(${body}))         .to("http://www.a-service.0com")         .setheader("webresponse", simple(${body})) //store response http call         .setbody(simple(${header.filebody})) //reset body original file body             .choice()                 .when(new predicate() {                     @override                     public boolean matches(exchange exchange) {                         message in = exchange.getin();                         string msg = in.getheader("webresponse");                          system.out.println(" response: " + msg);                          if(msg.contains("\"status\":\"ok\"")){                             return true;                         }else{                             return false;                         }                     }                 })                      // ok!!!                     .to("file:data/outbox_success")                 .otherwise()                     // not ok !!!                     .to("file:data/outbox_fail");

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod...
