Spring RestTemplate GET与参数
我必须打一个REST
电话,其中包括自定义标头和查询参数。我只设置HttpEntity
了标题(没有正文),然后使用以下RestTemplate.exchange()
方法:
HttpHeaders headers = new HttpHeaders();headers.set("Accept", "application/json");
Map<String, String> params = new HashMap<String, String>();
params.put("msisdn", msisdn);
params.put("email", email);
params.put("clientVersion", clientVersion);
params.put("clientType", clientType);
params.put("issuerName", issuerName);
params.put("applicationName", applicationName);
HttpEntity entity = new HttpEntity(headers);
HttpEntity<String> response = restTemplate.exchange(url, HttpMethod.GET, entity, String.class, params);
这在客户端失败,dispatcher servlet
因为无法将请求解析为处理程序。调试完成后,似乎没有发送请求参数。
当我POST使用请求正文和无查询参数进行交换时,它工作正常。
有人有什么想法吗?
回答:
为了轻松地操纵URL / path / params /等等,可以使用Spring的UriComponentsBuilder类。手动连接字符串比较干净,它会为你处理URL编码:
HttpHeaders headers = new HttpHeaders();headers.set("Accept", MediaType.APPLICATION_JSON_VALUE);
UriComponentsBuilder builder = UriComponentsBuilder.fromHttpUrl(url)
.queryParam("msisdn", msisdn)
.queryParam("email", email)
.queryParam("clientVersion", clientVersion)
.queryParam("clientType", clientType)
.queryParam("issuerName", issuerName)
.queryParam("applicationName", applicationName);
HttpEntity<?> entity = new HttpEntity<>(headers);
HttpEntity<String> response = restTemplate.exchange(
builder.toUriString(),
HttpMethod.GET,
entity,
String.class);
