Convert CachedOutputStream to a string.
After upgrading camel from 2.12 to 2.23 I have a problem on my route, same code same route.
The response after calling a endpoint is of type org.apache.camel.converter.stream.CachedOutputStream
I tried to convert the CachedOutputStream to a String.
String body = exchange.getIn().getBody(String.class);
logger.info("FJA the string after caling endpoint: " + body);
I dk.bankconnect.hub.Util efter FJA efter streng er:
-0��phjA����/h`�FhI[����G<�����,�Z���f���=��Rϝ��s#���O��~#�G�t
How to convert the CachedOutputStream to a string?
I tried many different things to avoid the response to come as a stream. However, I do not succeeded.
Here is a little snippet of my route:
from("direct:sdc:webservice")
.setProperty("webservice", constant(Boolean.TRUE))
.setProperty("duration", simple("Forwarding request to ${property.datacentral} datacentral"))
.choice().when().simple("${property.Tracked} == true").bean(Util.class, "dura-tion").end()
.bean(Util.class, "tracker")
.bean(Util.class, "foer")
.to(Util.getProperty("sdc.url"))
.bean(Util.class, "efter")
.convertBodyTo(Document.class)
.setProperty("duration", simple("Receiving response from ${proper-ty.datacentral} datacentral"))
.choice().when().simple("${property.Tracked} == true").bean(Util.class, "dura-tion").end()
.bean(Util.class, "tracker")
.setProperty(SoapError.FAULT, xpath("/soapenv:Envelope/soapenv:Body/soapenv:Fault/faultstring/text()", String.class).namespace("soapenv", Namespace.SOAP))
.end();
My convertBodyTo fails, because its suddenly a stream.
Ok, very short

This is not a String that is readable, but many special characters.

I am sending JSON object through TcpSocket. I deserialize it after destination receives. Usually first a few objects are sent and deserialized without issue! And then suddenly one comes with an extra curly braket only at the end then run time exception.
Seriosuly, what the hell is this ?
System.Text.Json.JsonException: ''}' is invalid after a single JSON value. Expected end of data. Path: $ | LineNumber: 0 | BytePositionInLine: 32.'
{"Value":3,"Name":"Blood Sugar"}}
while(true)
{
seperateSocketForEachRequest.Receive(byteMessage);
seperateSocketForEachRequest.Send(Encoding.UTF8.GetBytes("FF"));
string stringMessage = Encoding.UTF8.GetString(byteMessage);
stringMessage = stringMessage.Substring(0, stringMessage.IndexOf('\0'));
Object message = JsonSerializer.Deserialize<Object>(stringMessage);
}
////////////////////////////////////////
while (Form.isGenerate)
{
Data newData = dataType.generate(person.generatingParameters);
Thread.Sleep(500);
clientSocket.Send(Encoding.UTF8.GetBytes(JsonSerializer.Serialize<Data>(newData)));
byte[] messageReceivedByte = new Byte[1024];
clientSocket.Receive(messageReceivedByte);
}
I found the issue. It is caused of data transmission. Apparently same buffer is used for writing data received from socket and new data is written over old data. Therefore, when value of data is 2 digit number, no issue, when a data comes with 1 digit, boom.
{"Value":76,"Name":"Blood Sugar"}
{"Value":99,"Name":"Blood Sugar"}
{"Value":76,"Name":"Blood Sugar"}
{"Value":1,"Name":"Blood Sugar"}}
I have an endpoint who consumes Json with 2 attributes, like
{id='12344', data=byte_array}
so I've wrote a test
Feature: submitted request
Scenario: submitted request
* def convertToBytes =
"""
function(arg) {
var StreamUtils = Java.type('my.utils.StreamUtils');
// it reads stream and convert it to a byte array
return StreamUtils.getBytes(arg);
}
"""
Given url 'http://my-server/post'
And def image = convertToBytes(read('classpath:images/image_1.jpg'));
And request {id:1, data: "#(image)"}
When method POST
Then status 200
However is got an exception form karate without much details
ERROR com.intuit.karate - http request failed: [B cannot be cast to [Ljava.lang.Object;
Any hits how to submit byte arrays as a part of Json with karate?
I don't think you can do that. Either the whole request should be binary (byte-array) or you do a multi-part request, where binary is Base64 encoded. As far as I know you can't put binary inside JSON. There is something called Binary JSON though.
EDIT: after assuming that the byte[] has to be Base64 encoded:
Background:
* url demoBaseUrl
* def Base64 = Java.type('java.util.Base64')
Scenario: json with byte-array
Given path 'echo', 'binary'
And def encoded = Base64.encoder.encodeToString('hello'.bytes);
And request { message: 'hello', data: '#(encoded)' }
When method post
Then status 200
And def expected = Base64.encoder.encodeToString('world'.bytes);
And match response == { message: 'world', data: '#(expected)' }
I just added this test to the Karate demos, and it is working fine. Here is the commit.
I'm trying to recreate a scenario with the postman and there is a _csrf value in the previous GET request response body to be passed with the next POST request.
I Can't find a way to extract the value from POSTMAN.
NOTE: What I want is something similar to Regular Expression Extractor in Jmeter.If you have any Idea about extracting a value form the response body and setting it to a variable. Please let me know.
Cheers,

They use Cheerio
2.2.5 How to parse a HTML response to extract a specific value?
Presumed you want to get the _csrf hidden field value for assertions or later use from the response below:
To parse and retrive the value, we will use the cherrio JavaScript library:
responseHTML = cheerio(pm.response.text());
console.log(responseHTML.find('[name="_csrf"]').val());
Cheerio is designed for non-browser use and implements a subset of the jQuery functionality. Read more about it at
https://github.com/cheeriojs/cheerio
responseHTML = cheerio(pm.response.text());
var po= responseHTML.find('[name="_csrf"]').val();
console.log(po);
pm.environment.set("token", po);
/* You need to set the environment in Postman and capture the CSRF token in variable "here po" using a get request. Next in post request the environment variable token can be used */
Just made this JS in post man to parse Without a REGEx. Hope it will help people in the futur
Text to parse : Json : Extract data-id :
{
"code": "OK",
"response": {
"append": {
"html": {
"< .folders": "<a class=\"folder\" href=\"/foobarfoo\" data-id=\"ToExtract\"><div><i class=\"far fa-fw fa-folder\"></i></div><div class=\"folder-name\">blabla</div><div><div class=\"badge\">0</div></div></a>"
}
}
}
}
console.log(responseBody.response);
var jsonData = JSON.parse(responseBody);
var iStart = responseBody.indexOf("response\":")+10;
var scenarioId = responseBody.substr(iStart,10);
var iEnd = scenarioId.indexOf("}");
var scenarioId = scenarioId.substr(0,iEnd);
console.log("scenarioId:" + scenarioId + "iStart: "+ iStart + " scenarioId : " + scenarioId);
pm.environment.set("scenario", scenarioId);
I'm trying to build a very simple app that will just output the raw JSON object from an api.
So I want a function that will take a url parameter and ideally return the JSON string.
I have the following code:
decode: String -> String
decode jsonString =
Decode.decodeString jsonString
apiResonse : String -> String
apiResonse url =
let
url = "https://api.giphy.com/v1/gifs/random?api_key=dc6zaTOxFJmzC&tag=cats"
request = Http.get Decode.decodeString url
in
Http.send NewRequest request
But I'm struggling to understand the decoder part of the function. If anyone could help me that would be great.
If you just want to get the HTTP response as a string value, use Http.getString. The example you posted using Http.get assumes the result is in JSON and forces you to decode it to an Elm value.
Here is a modified example of the random cat generator code which just displays a dump of the response JSON instead of a cat picture:
getRandomGif : String -> Cmd Msg
getRandomGif topic =
let
url =
"https://api.giphy.com/v1/gifs/random?api_key=dc6zaTOxFJmzC&tag=" ++ topic
in
Http.send NewGif (Http.getString url)
Here is a working example on ellie-app.com
I am trying to make a post request on GDAX.
But I always receive a "invalid signature" message.
GDAX API Docs for creating request + signing: https://docs.gdax.com/#creating-a-request
Preshash string returns the following:
1500627733POST/orders{"price":"1000.0","size":"0.02","type":"limit","side":"sell","product_id":"BTC-EUR"}
My signature method:
public String generateSignature(String requestPath, String method, String body, String timestamp) {
try {
String prehash = timestamp + method.toUpperCase() + requestPath + body;
byte[] secretDecoded = Base64.getDecoder().decode(secretKey);
SecretKeySpec keyspec = new SecretKeySpec(secretDecoded, "HmacSHA256");
Mac sha256 = (Mac) Mac.getInstance("HmacSHA256").clone();
sha256.init(keyspec);
return Base64.getEncoder().encodeToString(sha256.doFinal(prehash.getBytes()));
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
My request method:
private boolean placeLimitOrder(String currencyPair, String side, String price, String size)
throws UnirestException {
String timestamp = Instant.now().getEpochSecond() + "";
String api_method = "/orders";
String path = base_url + api_method; //base_url = https://api.gdax.com
String method = "POST";
String b = "{\"price\":\"1000.0\",\"size\":\"0.02\",\"type\":\"limit\",\"side\":\"sell\",\"product_id\":\"BTC-EUR\"}";
JsonNode n = new JsonNode(b);
String sig = generateSignature(api_method, method,b, timestamp);
HttpResponse<JsonNode> rep = Unirest.post(path).header("accept", "application/json")
.header("content-type", "application/json")
.header("CB-ACCESS-KEY", publicKey)
.header("CB-ACCESS-PASSPHRASE", passphrase)
.header("CB-ACCESS-SIGN", sig)
.header("CB-ACCESS-TIMESTAMP", timestamp)
.body(n)
.asJson();
System.out.println(rep.getStatusText()); //Bad Request
System.out.println(rep.getBody().toString()); //invalid signature
System.out.println(sig); //returns something
return false;
}
I also tried to make a API Request Call with Insomnia but it returns the same message ("invalid signature").
Any clues?
Thank you very much in advance!
Looks like you are signing the price order data which is a string, but for the body in the post you are turning it into a json node. Which may not match when gdax decodes the signing and compares the payload data to the decrypted(signed body) when they receive it.
Why not just send the string as the body and remove the ".asJson"?
.body(b)
I was stuck on a similar issue when I was testing the API in C#. After 3 afternoons of trying. I tested sending the data as a string and I was able to get pass the invalid signature error.
I had the same problem.
I used http:
but the right one httpS:
Problem solved.
