[FIXED] How to pass JSON on a GET URL with Spring Webclient

Issue

I need to call an external service with URL that looks like this...

GET https://api.staging.xxxx.com/locations?where={"account":"bob"}

This is not my service and I have no influence over it, and my codebase at the moment is using Spring WebClient.

WebClient.create("https://api.staging.xxxx.com/")
.get()
.uri(uriBuilder -> uriBuilder.path("locations?where={'account':'bob'}").build())

Since WebClient sees the { bracket it tries to inject a value into the URL, which I don't want.

Can anyone suggest how I can do with with Spring WebClient?

Otherwise I will revert to OKHttp or another basic client to sent this request.

Solution

You can use UriUtils#encodeQueryParams to encode the JSON param:

String whereParam = "{\"account\":\"bob\"}";

 //...
uriBuilder
   .path("locations")
   .queryParam("where", UriUtils.encodeQueryParam(whereParam, StandardCharsets.UTF_8))
   .build()
