Spring RestTemplate postForObject带有头：webservice找不到我的头参数

Question

这是我的代码：

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
headers.add("companyId", companyId);
headers.add("password", password);              

HttpEntity<String> request = new HttpEntity<String>(headers);

RestTemplate restTemplate = new RestTemplate();

List<HttpMessageConverter<?>> messageConverters = new  ArrayList<HttpMessageConverter<?>>();
messageConverters.add(new MappingJacksonHttpMessageConverter());           
restTemplate.setMessageConverters(messageConverters);

LoginResponse response = (LoginResponse)restTemplate.postForObject(url, request, LoginResponse.class);

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

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

HttpEntity<MultiValueMap<String, String>> request = new HttpEntity<MultiValueMap<String, String>>(map, headers);

List<HttpMessageConverter<?>> messageConverters = new ArrayList<HttpMessageConverter<?>>();
messageConverters.add(new MappingJacksonHttpMessageConverter());    
messageConverters.add(new FormHttpMessageConverter());
restTemplate.setMessageConverters(messageConverters);

LoginResponse response = (LoginResponse) restTemplate.postForObject(url, request, LoginResponse.class); 

@JsonIgnoreProperties(ignoreUnknown = true)
public class ItcLoginResponse {

    public String loginToken;

    @JsonProperty("token")
    public String getLoginToken() {
        return loginToken;
    }

    public void setLoginToken(String loginToken) {
        this.loginToken = loginToken;
    }
}

Answer 1

您将设置一个头，指示您要发布一个表单(APPLICATION_FORM_URLENCODED)，但随后将companyId和password设置为HTTP头。

我怀疑你希望这些字段在你的请求中。

您还将创建HttpEntity ，这表明您将发布一个包含字符串的请求正文，但您提供的是头部，而不是字符串。
