Spring RestTemplate GET请求没有给出正确的响应

Question

When I perform a get request with RestTemplate, the server's response is not the same as what I get via a curl or in my browser

I've tried playing with the URL encoding and logging the url to the console to further troubleshoot but can't explain the discrepancy.

UriComponents uriComponents = UriComponentsBuilder.fromHttpUrl(URL + "search/all")
                .queryParam("keywords", UriUtils.encode(person, StandardCharsets.UTF_8))
                .build(true);
ResponseEntity<String> responseEntity = restTemplate.getForEntity(uriComponents.toUriString(), String.class);

The resultant URL from RestTemplate:
https://example.com/api/v3/search/all?keywords=%C3%89tienne%20Racicot
returns the response: {}

Performing: curl https://example.com/api/v3/search/all?keywords=%C3%89tienne%20Racicot
returns the response: {Person: {...} }

Answer 1

I was able to resolve my issue by changing the logging level for the RestTemplate class to debug. Add logging.level.org.springframework.web.client.RestTemplate=DEBUG to application.properties and you'll get a detailed log of the requests RestTemplate performs. This helped me notice that it was encoding the url I was passing a second time which I do not want. To avoid this pass uriComponents.toUri() to restTemplate.getForEntity(..) instead of a string.
