java - Spring 休息模板

Question

如何发送POST请求，消息正文中必须包含查询参数？

我尝试过:

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

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

但是这不起作用。我想将数据发送到 bitstamp api。

编辑:我的 Spring Bean 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:缺少 key 、签名和随机数参数

但应该是:未找到API key

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);
