弹簧休息模板

Question

如何发送 POST 请求，其中必须是消息正文中的查询参数？

我试过了：

MultiValueMap<String, String> map = new LinkedMultiValueMap<String, String>();
map.add("name", "xx");
map.add("password", "xx");

restTemplate.postForObject("URL", map, Response.class);

但它不起作用。我想将数据发送到 bitstamp api。

编辑：我的春豆似乎：

<bean id="restTemplate" class="org.springframework.web.client.RestTemplate">
    <property name="messageConverters">
        <list>
            <bean class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter" />
        </list>
    </property>
</bean>

编辑 2：我的代码似乎

List<MediaType> acceptableMediaTypes = new ArrayList<MediaType>();
acceptableMediaTypes.add(MediaType.APPLICATION_JSON);// or any other

HttpHeaders headers = new HttpHeaders();
headers.setAccept(acceptableMediaTypes);

HttpEntity<String> requestEntity = new HttpEntity<String>("key=XX&nonce=XX&signature=XX", headers);
ResponseEntity<AccountBalance> responseEntity = restTemplate.exchange(
"https://www.bitstamp.net/api/balance/", HttpMethod.POST, requestEntity, AccountBalance.class);

现在的响应是：缺少密钥、签名和随机数参数

但应该是：找不到 API 密钥

Answer 1

现在可以了，谢谢大家 :-)

MultiValueMap<String, String> body = new LinkedMultiValueMap<String, String>();
body.add("key", "XXX");
body.add("nonce", "XX");
body.add("signature", "XX");

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);

HttpEntity<?> requestEntity = new HttpEntity<Object>(body, headers);

ResponseEntity<AccountBalance> responseEntity = restTemplate.exchange(bitstampBalanceUrl, HttpMethod.POST,
                requestEntity, AccountBalance.class);

Answer 2

你必须使用restTemplate.exchange

示例：

List<MediaType> acceptableMediaTypes = new ArrayList<MediaType>();
acceptableMediaTypes.add(MediaType.APPLICATION_JSON);// or any other

HttpHeaders headers = new HttpHeaders();
headers.setAccept(acceptableMediaTypes);

HttpEntity<String> requestEntity = new HttpEntity<String>("name=XX&password=XX",headers);
ResponseEntity<Response> responseEntity = restTemplate.exchange("URL", HttpMethod.POST, requestEntity, Response.class);
