Spring使用RestTemplate模拟form提交示例

@Bean
public RestTemplate restTemplate(){
   return new RestTemplate();
}

@Service
public class SmsService {
   //注入RestTemplate
  @Autowired
  RestTemplate restTemplate;


  public String sendMsg(String phoneNum,String text){


    //请求头设置
    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);


    //提交参数设置
    MultiValueMap<String,String> p = new LinkedMultiValueMap<>();
    p.add("username","xxx");
    p.add("password","yyy");
    p.add("phoneNum",phoneNum);
    p.add("content",text);

    //提交请求
    HttpEntity< MultiValueMap<String,String>> entity = new HttpEntity< MultiValueMap<String,String>>(p,headers);

    String result = restTemplate.postForObject("http://....",entity,String.class);

    return result;

  }
}
