Spring Basic OAuth抛出错误请求异常

Question

嗨，我试图连接弹性搜索使用Spring rest模板，但它给例外说不好的请求

 String plainCreds = "elasticsearch:*****";
            byte[] plainCredsBytes = plainCreds.getBytes();
            byte[] base64CredsBytes = Base64.encodeBase64(plainCredsBytes);
            String base64Creds = new String(base64CredsBytes);

            HttpHeaders headers = new HttpHeaders();
            headers.set("Authorization", "Basic " + base64Creds);

            final String url = "https://ff92ba95318093026b7a06180f2b2d19.us-east-1.aws.found.io:9243/jinkjobposts_dev_v1/jobPosts";

            RestTemplate restTemplate = new RestTemplate();
            restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());

            HttpEntity<String> request = new HttpEntity<>( headers);
            Log.d("location", "before exchange");
            ResponseEntity<JobPosts> response = restTemplate.exchange(url, HttpMethod.POST, request, JobPosts.class);

            JobPosts jobPosts = response.getBody();

            Log.d("location", "after exchange");
            list = Arrays.asList(jobPosts);

它给出了这个例外。

请告诉我这是我第一次这么做

这不是授权问题。您的url只是缺少末尾的\u searchendpoint，因此出现了错误HTTP 400。

 final String url = "https://ff92ba95318093026b7a06180f2b2d19.us-east-1.aws.found.io:9243/jinkjobposts_dev_v1/jobPosts/_search";
