使用spring rest进行POST REST API的身份验证模板

Question

我想使用Spring RESTTemplate将对象发布到Web服务器并返回。

下面的代码段：

String authStringEncoded = 
       Base64.getEncoder().encodeToString 
        ("582f3e4a9e933168ea1048e6:98c6f2736c5f02279d767ce7ddfe7e5d".getBytes("utf-8")); 


     HttpHeaders headers = new HttpHeaders(); 
     headers.add("Authorization", "Basic " + authStringEncoded); 


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

     RestTemplate rt = new RestTemplate(); 
     rt.getMessageConverters().add(new MappingJackson2HttpMessageConverter()); 
     rt.getMessageConverters().add(new StringHttpMessageConverter()); 
     String uri = new String(REGISTERING_NEW_DEVICES.replace("{devicetype-id}", KIT_TYPE_ID)); 


     TdkDevice deviceC3DF86B = new TdkDevice(); 
     deviceC3DF86B.setId("C3DF86B"); 
     deviceC3DF86B.setPal("44CFFFC9D5F8E8B2F36"); 

     DeviceRegistration deviceRegistration = new DeviceRegistration(); 
     deviceRegistration.getIds().add(deviceC3DF86B); 

     rt.postForObject(uri, HttpMethod.POST, request, deviceRegistration, DeviceRegistration.class); 

但我得到一个编译错误：

The method postForObject(String, Object, Class<T>, Object...) in the type RestTemplate is not applicable for the arguments (String, HttpMethod, HttpEntity<String>, DeviceRegistration, 
Class<DeviceRegistration>) 

Answer 1

您的服务请求应该像下面：

rt.postForObject(uri, request, DeviceRegistration.class); 

根据春季RestTemplate api，postForObject方法的参数应该如下：

个

参数：

• 网址 - 网址
• 要求 - 要发布的对象（可以为null）
• 的responseType - 返回值的
• uriVariables类型 - 变量扩大模板
