HttpClient的HttpResponse返回非格式化字符串

Question

我已经创建了一个post请求，该请求使用HttpClient执行。这将返回一个响应，从中检索实体，并将其转换为字符串以读取响应值。响应包含正确的数据，但它会丢失所有相关的XML标记，并且只包含数据。但是，当我通过CURL或Postman发出这个post请求时，响应包含XML标记。我不知道我做错了什么。这是我尝试过的：

// Create HTTP Post Request
HttpPost requestPost = new HttpPost(url);
// Create Auth
String auth = username + ":" + password;
byte[] encodedAuth = Base64.encodeBase64(auth.getBytes());
String authHeader = "Basic " + new String(encodedAuth);
requestPost.setHeader(HttpHeaders.AUTHORIZATION, authHeader);
requestPost.setHeader("Content-Type", "application/x-www-form-urlencoded");

// Create the request parameter body
List<BasicNameValuePair> urlParameters = new ArrayList<>();
urlParameters.add(new BasicNameValuePair("functionName", functionName));
urlParameters.add(new BasicNameValuePair("objectType", objectType));
urlParameters.add(new BasicNameValuePair("inputParameter", inputParameter));
urlParameters.add(new BasicNameValuePair("inputTableParameter", inputTableParameter));

// Execute request
UrlEncodedFormEntity entity = new UrlEncodedFormEntity(urlParameters);
requestPost.setEntity(entity);

// bypass SSL security
SSLContext context = SSLContext.getInstance("TLSv1.2");
TrustManager[] trustManager = new TrustManager[] {
        new X509TrustManager() {
            @Override
            public X509Certificate[] getAcceptedIssuers() {
                return new X509Certificate[0];
            }
            @Override
            public void checkClientTrusted(X509Certificate[] certificate, String str) {}
            @Override
            public void checkServerTrusted(X509Certificate[] certificate, String str) {}
        }
};
context.init(null, trustManager, new SecureRandom());
SSLConnectionSocketFactory socketFactory = new SSLConnectionSocketFactory(context,
            SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

HttpClient client = HttpClientBuilder.create().setSSLSocketFactory(socketFactory).build();
HttpResponse response = client.execute(requestPost);

//Get response
String result = EntityUtils.toString(response.getEntity(), "UTF-8");
return result;

在不发布所有结果的情况下，我的最终结果如下所示: results 002020-07-31100In Process2020-07-312020-07-312020-07-3100002210000825255003Calculated00002210000825255EUREuro0012020-07-3100:00:00 ...等

但在postman或CURL中，它使用XML标记进行了很好的格式化：

<OUTPUT>
    <EN_ERROR_CD>00</EN_ERROR_CD>
    <ES_APPLICATION>
        <EFFECTIVE_DT>2020-07-31</EFFECTIVE_DT>

        <STARTTIME_TM>00:00:00</STARTTIME_TM>
...etc

作为参考，我的CURL请求是这样的：

curl -u username:password -d "functionName=/RETRIEVE&objectType=obj&inputParameter=<INPUT><IV_APPLNR_CD>10000000002553402</IV_APPLNR_CD><IS_REQUESTED_ELEMENTS></IS_REQUESTED_ELEMENTS><IF_READ_JOURNAL></IF_READ_JOURNAL><IF_READ_CBC>X</IF_READ_CBC></INPUT>&inputTableParameter=" -H "Content-Type: application/x-www-form-urlencoded" -X POST https://hostname:port/test/service/service.do

我希望这些信息对说明这个问题有帮助。非常感谢您的帮助！

可以通过在创建post请求时添加以下行来解决此问题：

requestPost.setHeader(HttpHeaders.ACCEPT_CHARSET, "true");
