如何使用 URL 参数进行 GET API 请求？

Question

Client client = ClientBuilder.newClient();
urlApi="https://localhost:123/demo/api/v1/rows/search?";
WebTarget webTarget = client.target(urlApi);
for (Map.Entry<String, String> entry : queryParams.entrySet()) {
    webTarget.queryParam(entry.getKey(), entry.getValue());
}
webTarget.queryParam("searchConditions",webTarget.queryParam("mobileNo","+9999999999"));

Invocation.Builder builder = webTarget.request();

builder.header("id", "ABC");
String asB64 = Base64.getEncoder().encodeToString("ABC:PWD".getBytes("utf-8"));
logger.debug("Calling  API "+urlApi);
builder.header("Authorization", "Basic "+asB64);
builder.header("Content-type", MediaType.APPLICATION_JSON);     
response = builder.get();
responseData = response.readEntity(String.class);
System.out.println(responseData);

我正在尝试使用 searchCondition 作为键和值作为 {mobileNo="+919999999999"} 的 GET 请求，但我无法让它工作。

除此之外，我如何打印请求“标题”以及“查询参数”？提前谢谢你

我认为您需要对值输入进行编码，如下所示：

webTarget.queryParam("searchCondition", URLEncoder.encode("{mobileNo=\"+919999999999\"}", StandardCharsets.UTF_8.toString()));

UDPATE： 使用 Spring 的其余客户端示例：

@Test
public void testStack() throws Exception {
    RestTemplate rest = new RestTemplate();
    String fooResourceUrl="http://localhost:8080/usersParam?";
    RestTemplate restTemplate = new RestTemplate();
    String parameter = "{mobileNo=\"+919999999999\"}";

    ResponseEntity<String> response = restTemplate.getForEntity(fooResourceUrl + "parameter=" + URLEncoder.encode(parameter, StandardCharsets.UTF_8.toString() ), String.class);
    assertThat(response.getStatusCode()).isEqualTo(HttpStatus.OK);
}

这将是其余的服务：

@RequestMapping(method = RequestMethod.GET, value="/usersParam")
    public User getUsersInfo(@RequestParam String parameter) throws UnsupportedEncodingException {
         System.out.println(URLDecoder.decode(parameter, StandardCharsets.UTF_8.toString() ));
        return null;
    }
