duplicated quotation marks in java multipart request

I'm trying to make a multipart request using restassured. The request fails with the tested API telling me that the "information" part of the request is not an object. Here is my code:
RequestSpecification request;
Options options = Options.builder()
.printMultiliner()
.build();
RestAssuredConfig config = CurlLoggingRestAssuredConfigFactory.createConfig(options).multiPartConfig(MultiPartConfig.multiPartConfig().defaultCharset(StandardCharsets.UTF_8));
request = given()
.relaxedHTTPSValidation()
.config(config)
.header("Authorization", "Bearer " + LoginSteps.accessToken)
.queryParam("memberId", memberId)
.queryParam("policyId", policyId)
.contentType(String.valueOf(ContentType.MULTIPART_FORM_DATA))
.multiPart("information", "{\"description\":\"info\"}")
.multiPart("documents", new File(filePath), contentType)
.log().everything();
return request.post(baseUrl + endpoint);
and now here is the weird part. The standard restassured log looks like this:
Request method: POST
Request URI: myUri/?param1=149479812&param2=19281999
Proxy: <none>
Request params: <none>
Query params: param1=149479812
param2=19281999
Form params: <none>
Path params: <none>
Headers: Authorization=Bearer aToken
Accept=*/*
Content-Type=multipart/form-data; charset=ISO-8859-1
Cookies: <none>
Multiparts: ------------
Content-Disposition: form-data; charset=ISO-8859-1; name = information; filename = file
Content-Type: text/plain
{"description":"info"}
------------
Content-Disposition: form-data; charset=ISO-8859-1; name = documents; filename = testFile.jpg
Content-Type: image/jpg
src\test\resources\testData\testFile.jpg
Body: <none>
Being a bit desperate to determine the cause of the issue, I also turned on curl logging and here's what I saw:
13:58:05.312 [main] DEBUG curl - curl "myUri/?param1=149479812&param2=19281999" ^
--request POST ^
--header "Authorization: Bearer aToken ^
--header "Accept: */*" ^
--header "Host: theHost" ^
--header "Connection: Keep-Alive" ^
--header "User-Agent: Apache-HttpClient/4.5.13 (Java/11)" ^
--form "information={""description"":""info""};type=text/plain; charset=US-ASCII" ^
--form "documents=#testFile.jpg;type=image/jpg" ^
--compressed ^
--insecure ^
--verbose
As you can see, the content of "information" here has duplicated quotation marks. Which seems to be the cause of why this is failing. I also copy-pasted everything into Postman and it passes, and returns a 201 as expected. Log and screenshot below:
POST myUri/?param1=149479812&param2=19281999 {
"Request Headers": {
"authorization": "Bearer aToken"
"user-agent": "PostmanRuntime/7.29.0",
"accept": "*/*",
"postman-token": "bb25e9db-87c0-4fdd-959a-e4229ed36e7a",
"host": "host",
"accept-encoding": "gzip, deflate, br",
"connection": "keep-alive",
"content-type": "multipart/form-data; boundary=--------------------------115811667537577795637808",
"content-length": "28196"
},
"Request Body": {
"information": "{\"description\":\"info\"}",
"documents": ""
}
I have honestly no idea what I'm doing wrong here. When I remove the quotation marks, I get no quotation marks. when I insert one I get two in the curl log. I don't think the API is at fault, as the same request works using postman. Can anyone help, please?

After configuring the service to show logs of what requests are arriving, I found out that the quotation marks are not duplicated. It turns out the curl logger was responsible for that. And the request did not pas due to a bug in the API

How to set Request Body parameter in rest api

I have api using curl
curl -X PUT "http://localhost:8080/kie-server/services/rest/server/containers/containerid/tasks/210/expiration" -H "accept: application/json" -H "content-type: application/json" -d "{ \"java.util.Date\" : 1540025263987}"
Now I want to call this api using java code :
I am using javax.ws.rs.PUT class for api calling and HttpConnection class.
I have set the requestMethod(POST) and request property.
This is url i am using :
http://localhost:8080/kie-server/services/rest/server/containers/"+containerId+"/tasks/"+taskId+"/expiration
url = new URL( http://localhost:8080/kie-server/services/rest/server/containers/"+containerId+"/tasks/"+taskId+"/expiration);
conn.setRequestMethod(PUT);
conn.setRequestProperty("Accept", "application/json");
conn.setRequestProperty("Content-Type", "application/json");
I want to pass this parameter to api but not sure which method to use ?
{java.util.Date:1534343434"};
This parameter is passed in body.
Can anyone suggest how do I pass this parameter in java rest api ??

Spring oauth2 Authorization provider

I am new to Oauth, I have application with Spring Oauth2 with xml
configuration. Have taken reference from
http://www.beingjavaguys.com/2014/10/spring-security-oauth2-integration.html
So the URL below to get the token is
http://localhost:8080/SpringRestSecurityOauth/oauth/token?grant_type=password&client_id=restapp&client_secret=restapp&username=beingjavaguys&password=spring#java
It gives the token reseponse.
So here in request url the client_id is hardcoded inside xml file.And I want to send the clientId,grantType at run time.
What things need to be taken care of here.

Normally you would send the client_id/client_secret in a header.
OAuth2 is only secure if https is used as there are secret data transmitted.
Here an example (angularjs):
auth = 'Basic ' + window.btoa(client_id + ':' + client_secret);
$http.defaults.headers.common.Authorization = auth;
$http.defaults.headers.common['X-Requested-With'] = 'XMLHttpRequest';
grantparam= 'grant_type=password&username='+loginData.username + '&password=' + loginData.password;
$http.post('https://localhost:8123/oauth/token?'+grantparam)
here in curl from postman:
curl -X POST -H "Accept: application/json" -H "Content-Type: application/x-www-form-urlencoded" -H "Authorization: Basic 111111111111111" -H "Cache-Control: no-cache" -H "Postman-Token: 11111111-111111111111111" "https://localhost:8443/sf/api/oauth/token?grant_type=password&username=11111111111&password=**********"

How to send -u data of Curl in Rest client

I have a Curl request like:
curl -u "key:value" -H "headers" https://example.com
So, when I try to create a Rest client using this curl request in Java I am confused where to send the -u data in my request. Do we need to send it in Header or as URL parameter. Can somebody help me and tell me how can I send this -u in my Java code?
This is the code I am using:
URL url = new URL("https://example.com");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setDoOutput(true);
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type", "application/json");
conn.setRequestProperty("Headers", "Value");
***conn.setRequestProperty("u", "key:Value");***

The header Authorization: Basic base64encoded(user:pass) works for this question.

Curl oAuth equivalent in Java

I can't find the way to reproduce the following curl oAuth authentication call in Java:
curl 'https://id.herokuapp.com/oauth/token' -H 'Content-Type: application/x-www-form-urlencoded' -H 'Accept: application/json' -H 'Authorization: Basic AUTH_VALUE' -H 'Connection: keep-alive' --data 'username=_USERNAME&password=_PASSWORD&grant_type=password&scope=read%20write&client_secret=_SECRET&client_id=_CLIENT_ID' --compressed
I don't know how to pass the --data value to the call.

If you're using standard java.net.URL it can be done but the syntax is rather cumbersome, I suggest that you try using HTTP Components library. You should end up with something like this:
final HttpUriRequest request = RequestBuilder.get()
.setUri("https://id.herokuapp.com/oauth/token")
.setHeader("Content-Type", "application/x-www-form-urlencoded")
.setHeader("Accept", "application/json")
.setHeader("Authorization", "Basic AUTH_VALUE")
.addParameter("username", "_USERNAME")
.addParameter("password", "_PASSWORD")
.addParameter("grant_type", "password")
.addParameter("scope", "read write")
.addParameter("client_secret", "_SECRET")
.addParameter("client_id", "_CLIENT_ID")
.build();
final HttpClient client = HttpClientBuilder.create().build();
final HttpResponse response = client.execute(request);
final HttpEntity entity = response.getEntity();
System.out.println(EntityUtils.toString(entity)); // or whatever processing you need
GZip/deflate and keep alive handling is provided out of the box if the HttpClient is created using HttpClientBuilder.
