无效的 HTTP 方法：PATCH

Question

尝试其他解决方案后 HttpURLConnection 无效的 HTTP 方法：PATCH

我收到无效的 HTTP 方法：JAVA 7 的 PATCH 异常。 无法选择更新 JAVA，所以我必须坚持解决方法。

我正在使用调用来调用这样的请求

Invocation invoke = reqBuilder.build(getHTTPVerb(), Entity.entity(requestJSON, MediaType.APPLICATION_JSON));
getWebTarget().request(MediaType.APPLICATION_JSON).header("Authorization", getAuthorization()).accept(MediaType.APPLICATION_JSON);

getHTTPVerb()

返回字符串“POST”或“PATCH”。

使用 PATCH 方法时遇到问题。

在提到的问题中，我还没有尝试过一种解决方案：

conn.setRequestProperty("X-HTTP-Method-Override", "PATCH");
conn.setRequestMethod("POST");

conn

是

HttpURLConnection

实例。

但我不确定如何从调用类或任何属性中获取

HttpURLConnection

。

任何指示或帮助将不胜感激。

使用 apache http 客户端的 PATCH 方法示例：

    try {

        //This is just to avoid ssl hostname verification and to trust all, you can use simple Http client also
        CloseableHttpClient httpClient = HttpClientBuilder.create().setSSLContext(new SSLContextBuilder().loadTrustMaterial(null, TrustAllStrategy.INSTANCE).build())
                .setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE).build();

        HttpPatch request = new HttpPatch(REST_SERVICE_URL);
        StringEntity params = new StringEntity(JSON.toJSONString(payload), ContentType.APPLICATION_JSON);
        request.setEntity(params);
        request.addHeader(org.apache.http.HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON_VALUE);
        request.addHeader(HttpHeaders.ACCEPT, MediaType.APPLICATION_JSON_VALUE);
        request.addHeader(HttpHeaders.AUTHORIZATION, OAuth2AccessToken.BEARER_TYPE + " " + accessToken);
        HttpResponse response =     httpClient.execute(request);            

        String statusCode = response.getStatusLine().getStatusCode();

    } catch (Exception ex) {
        // handle exception here
    }

RestTemplate 的等效示例：

    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_JSON);
    headers.add("Authorization", OAuth2AccessToken.BEARER_TYPE + " " + accessToken);
    final HttpEntity<String> entity = new HttpEntity<String>(JSON.toJSONString(payload), headers);
    RestTemplate restTemplate = new RestTemplate();
    try {
        ResponseEntity<String> response = restTemplate.exchange(REST_SERVICE_URL, HttpMethod.PATCH, entity, String.class);
        String statusCode =  response.getStatusCode();
    } catch (HttpClientErrorException e) {
        // handle exception here
    }
