我的问题是调用php webservice在java代码中工作。我是一个非常新手。 请问，我如何在java应用程序中调用webservice。感谢。
答案 0 :(得分：0)
HttpUrlConnection 类用于所有类型的HTTP请求。你可以找到很多用法例子。
这样，您的Java应用程序将通过HTTP调用服务器，运行PHP代码。
答案 1 :(得分：0)
建立从Java到您的php服务器的HTTP连接，如下所示
private static void sendGET(String GET_URL) throws IOException {
URL obj = new URL(GET_URL);
HttpURLConnection con = (HttpURLConnection) obj.openConnection();
con.setRequestMethod("GET");
con.setRequestProperty("User-Agent", USER_AGENT);
int responseCode = con.getResponseCode();
System.out.println("GET Response Code :: " + responseCode);
if (responseCode == HttpURLConnection.HTTP_OK) { // success
BufferedReader in = new BufferedReader(new InputStreamReader(
con.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
// print result
System.out.println(response.toString());
} else {
System.out.println("GET request not worked");
}
}
