How to pass JSON on a GET URL with Spring Webclient-CodePudding

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.

One way to achieve this is to manually url encode the values before passing them to the uri builder.

Also I think that you should use queryParam() to specify query parameters.

uriBuilder -> 
  uriBuilder.path("locations")
            .queryParam("where", "{'account': 'bob'}")
            .build()

Another option would be to configure the encoding mode when creating the WebClient

 DefaultUriBuilderFactory factory = new DefaultUriBuilderFactory();
 factory.setEncodingMode(DefaultUriBuilderFactory.EncodingMode.NONE);
 WebClient.builder().uriBuilderFactory(factory).build();

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()
