[英]How can I avoid escaping a WebTarget query parameter?
I want to turn off URL encoding for Jersey requests, or for certain parameters.我想关闭 Jersey 请求或某些参数的 URL 编码。
The server I'm talking to requires the format of example.com/path?query=foo:bar
我正在与之交谈的服务器需要
example.com/path?query=foo:bar
的格式
With Jackson WebTarget,使用 Jackson WebTarget,
final WebTarget target = ClientBuilder.newClient()
.target(url)
.queryParam("query", "{queryVal}")
.resolveTemplate("queryVal", "foo:bar");
Sadly this produces example.com/path?query=foo bar
which is not accepted by the server.遗憾的是,这会产生服务器不接受的
example.com/path?query=foo bar
。
I've searched a lot for this and the only promising avenue seems to be something to do with javax.ws.rs.core.Configuration
, but I haven't gotten far with that yet.我为此搜索了很多,唯一有希望的途径似乎与
javax.ws.rs.core.Configuration
,但我还没有深入了解。
I figured it out: The solution is to use a request filter as documented in Advanced Features of the Client API我想通了:解决方案是使用 客户端 API 的高级功能中记录的请求过滤器
final WebTarget target = ClientBuilder.newClient()
.target(url)
.queryParam("query", "{queryVal}")
.resolveTemplate("queryVal", "foo:bar")
.register(Filter.class)
and then we have然后我们有
@Provider
public class Filter implements ClientRequestFilter {
private static final Logger logger = LoggerFactory.getLogger(Filter.class);
@Override
public void filter(ClientRequestContext ctx) throws IOException {
try {
logger.debug("Before: {}", ctx.getUri());
//this is gonna get ugly
ctx.setUri(new URI(
URLDecoder.decode(ctx.getUri().toString(), StandardCharsets.UTF_8.toString())));
logger.debug("After: {}", ctx.getUri());
} catch (URISyntaxException e) {
e.printStackTrace();
}
}
}
Output:输出:
com.example.client.Filter : Before: http://example.com/path?query=foo%3Abar
com.example.client.Filter : After: http://example.com/path?query=foo:bar
