Java Question

Jersey rest client not adding query parameters

I'm trying to make a simple jersey rest client for google search api.

Client client = ClientBuilder.newClient();
WebTarget target = client.target("https://www.googleapis.com/customsearch/v1");
target.queryParam("q", "mobile");
Response response = target.request().get();
System.out.println(response.readEntity(String.class));


As you've noticed I haven't included
key
and
cx
. Don't worry about that, it's just a simple demo.
When visiting the url
https://www.googleapis.com/customsearch/v1?q=mobile
, the response is

{
"error": {
"errors": [
{
"domain": "usageLimits",
"reason": "dailyLimitExceededUnreg",
"message": "Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup.",
"extendedHelp": "https://code.google.com/apis/console"
}
],
"code": 403,
"message": "Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup."
}
}


Which is correct since I haven't included
key
and
cx
. When I execute the code above, the response I'm getting is

{
"error": {
"errors": [
{
"domain": "global",
"reason": "required",
"message": "Required parameter: q",
"locationType": "parameter",
"location": "q"
}
],
"code": 400,
"message": "Required parameter: q"
}
}


Which is equivalent of visiting the url without any parameters (
https://www.googleapis.com/customsearch/v1
), although I've added this
target.queryParam("q", "mobile");
. Am I doing something wrong?

The code above belongs to a mavenized project and the dependency is

<dependency>
<groupId>org.glassfish.jersey.core</groupId>
<artifactId>jersey-client</artifactId>
<version>2.14</version>
</dependency>

Answer

chain the call

Response response= client.target("https://www.googleapis.com/customsearch/v1")
.queryParam("q", "mobile").request().get();

from the docs:

Returns: a new target instance.
