Question

有人可以告诉我如何使用RestTemplate使用Authorization来发布HttpEntity对象。我在测试应用程序中使用以下代码

客户端：

public class FifthWay extends Thread {

    public void run() {
        String plainCreds = "anuj:khare";
        byte[] plainCredsBytes = plainCreds.getBytes();
        byte[] base64CredsBytes = Base64.encodeBase64(plainCredsBytes);

        String base64Creds = new String(base64CredsBytes);
        HttpHeaders headers = new HttpHeaders();
        headers.add("Authorization", "Basic " + base64Creds);

        HttpEntity<String> postRequest = new HttpEntity<String>("FifthWay",headers);

        RestTemplate rt = new RestTemplate();
        rt.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
        rt.getMessageConverters().add(new StringHttpMessageConverter());

        String postUri = new String("http://169.194.48.182:8080/trade-capture-service/deals/persist");

        ResponseEntity<String> responseForPost = rt.exchange(postUri,HttpMethod.POST, postRequest, String.class);
        String responseStringForPost = responseForPost.getBody();
        System.out.println(responseStringForPost);
    }

}

服务器端：

@Controller
@RequestMapping("/deals")
public class RestController {
...
...
@RequestMapping(value = "/check", method = RequestMethod.GET)
    public @ResponseBody
    String justACheck() {
        System.out.println("It Works");
        return "It works";
    }

得到如下错误：

Exception in thread "Thread-4" org.springframework.web.client.HttpClientErrorException: 415 Unsupported Media Type

OR

Exception in thread "Thread-4" org.springframework.web.client.HttpClientErrorException: 400 Bad Request

请帮忙

以下是RestTemplate交换的示例：

RestTemplate restTemplate = new RestTemplate();
restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
 HttpHeaders requestHeaders = new HttpHeaders();
 final HttpEntity entity = new HttpEntity(restCanvas, requestHeaders);
return restTemplate.exchange(canvasAddUrl + value, HttpMethod.POST, entity, Integer.class);

这里canvasAddURL是您希望使用context-path调用的URL。如果你想给它添加一个cookie，知道，我已经删除了那段代码，因为大部分时间都没有必要。返回值为ResponseEntity<Integer>。看看这个。
