用于查询参数的Java Spring resttemplate字符编码

UriComponentsBuilder builder = UriComponentsBuilder.fromUriString(url)
        .queryParam("param1", value1)
        .queryParam("param2", value2)
        // 设置查询参数的编码方式
        .encode(Charset.forName("UTF-8"));

String encodedUrl = builder.toUriString();

MultiValueMap<String, String> params = new LinkedMultiValueMap<>();
params.add("param1", value1);
params.add("param2", value2);

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
// 设置查询参数的编码方式
headers.set("Charset", "UTF-8");

HttpEntity<MultiValueMap<String, String>> requestEntity = new HttpEntity<>(params, headers);

ResponseEntity<String> response = restTemplate.exchange(url, HttpMethod.GET, requestEntity, String.class);

String encodedValue1 = URLEncoder.encode(value1, "UTF-8");
String encodedValue2 = URLEncoder.encode(value2, "UTF-8");

String url = "http://example.com/api?param1=" + encodedValue1 + "&param2=" + encodedValue2;
