Examples with ErrorConverter io.vertx.ext.web.client.predicate.ErrorConverter used on opensource projects

Example 1 with ErrorConverter

use of io.vertx.ext.web.client.predicate.ErrorConverter in project vertx-web by vert-x3.

the class WebClientExamples method predicateCustomErrorWithBody.

public void predicateCustomErrorWithBody() {
    ErrorConverter converter = ErrorConverter.createFullBody(result -> {
        // Invoked after the response body is fully received
        HttpResponse<Buffer> response = result.response();
        if (response.getHeader("content-type").equals("application/json")) {
            // Error body is JSON data
            JsonObject body = response.bodyAsJsonObject();
            return new MyCustomException(body.getString("code"), body.getString("message"));
        }
        // Fallback to defaut message
        return new MyCustomException(result.message());
    });
    ResponsePredicate predicate = ResponsePredicate.create(ResponsePredicate.SC_SUCCESS, converter);
}

Example 2 with ErrorConverter

use of io.vertx.ext.web.client.predicate.ErrorConverter in project vertx-web by vert-x3.

the class PredicateInterceptor method handle.

@Override

    if (httpContext.phase() == ClientPhase.RECEIVE_RESPONSE) {
        // Run expectations
        HttpRequestImpl request = (HttpRequestImpl) httpContext.request();
