我想獲取http響應的String返回類型，我獲取http觸發請求的觸發器

Question

我想為觸發的http發布請求獲取http響應的String返回類型，但是我的return變量給出錯誤

“消息無法解析為變量”

隨后，我必須將該返回字符串值轉換為json字符串數據。

這是我的代碼。

public String sendPOST(String _postData) {

    CloseableHttpClient httpClient = HttpClients.createDefault();
    HttpPost httpPost = new HttpPost(POST_URL);
    httpPost.addHeader("User-Agent", USER_AGENT);

    StringEntity entity = new StringEntity(_postData, HTTP.UTF_8);
    entity.setContentType("application/json");
    httpPost.setEntity(entity);

    CloseableHttpResponse httpResponse;
    try {
        httpResponse = httpClient.execute(httpPost);

        System.out.println("POST Response Status:: " + httpResponse.getStatusLine().getStatusCode());

        BufferedReader reader = new BufferedReader(new InputStreamReader(httpResponse.getEntity().getContent()));

        String inputLine;
        StringBuffer response = new StringBuffer();

        while ((inputLine = reader.readLine()) != null) {
            response.append(inputLine);

            String message = org.apache.commons.io.IOUtils.toString(reader);
            String type = message.getClass().getName();

            System.out.println(type);
            System.out.println("Final : " + message);
        }
        reader.close();

        // print result
        System.out.println(response.toString());
        httpClient.close();
    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    return message;
  }

因為您在循環外使用本地“消息”變量。 添加全局“ message”變量，應該可以解決您的問題。
