405 - 不允许从struts调用web服务的方法

Question

我有一个调用Web服务的数据访问对象。在我的浏览器中，我可以使用网址访问网络服务并且成功。

http://mycompany:9080/ReportingManager/service/repManHealth/importHistoryTrafficLightStatus.json

但是当我尝试在我的数据访问对象中执行下面的代码时，我收到405错误，说明方法不允许。

String requestURI = "http://mycompany:9080/ReportingManager/service/repManHealth/importHistoryTrafficLightStatus.json";
URL url = new URL(requestURI);
HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();
httpCon.setDoOutput(true);
httpCon.setRequestMethod("GET");
httpCon.setRequestProperty("Accept", "application/json");

OutputStreamWriter out = new OutputStreamWriter(
httpCon.getOutputStream());

int responseCode = httpCon.getResponseCode();
String responseMessage = httpCon.getResponseMessage();

BufferedReader rd = new BufferedReader(new InputStreamReader(httpCon.getInputStream()));
StringBuffer sb = new StringBuffer();
String line = null;
while ((line = rd.readLine()) != null) {
    sb.append(line);
}
rd.close();

String jsonResponse = sb.toString();

out.close();
httpCon.disconnect();   

有人可以帮我解决这里可能出错的问题吗？

也许有更好的方法来执行外部应用程序的Web服务并使用struts读取响应？或者人们认为这种方法没问题？

感谢

如果你正在使用GET方法。请尝试以下代码。

string url = String.Format("http://somedomain.com/samplerequest?greeting={0}",param);

WebClient serviceRequest = new WebClient();
serviceRequest.Headers[HttpRequestHeader.ContentType] = "application/json";
string response = serviceRequest.DownloadString(new Uri(url));

感谢你的想法，但不是他们的想法是对的。我使用下面的代码修复了405 ...

    String requestURI = "http://myserver:9080/ReportingManager/service/repManHealth/importHistoryTrafficLightStatus.json";
    URL url = new URL(requestURI);
    URLConnection conn = url.openConnection();
    InputStream in = conn.getInputStream();
    BufferedReader rd = new BufferedReader(new InputStreamReader(in));
    StringBuffer sb = new StringBuffer();
    String line = null;
    while ((line = rd.readLine()) != null) {
        sb.append(line);
    }
    rd.close();

致电httpCon.getOutputStream());，您不再发送HTTP GET，而是HTTP POST。

注意：这是假设您最终获得Sun提供的实施。为了向后兼容，将把GET更改为POST。
