我有一个使用 Spring Security 进行身份验证的应用程序我正在尝试从 j2ME midlet 连接到该应用程序
所以我使用 post 方法从 j2me 应用程序发送 HTTP 请求来发送用户名和密码，但它不起作用
发布方法代码很好。它适用于同一应用程序的其他服务（不需要身份验证）
但是当涉及到身份验证时，我得到了响应代码 302
这是我的代码
OutputStream os = null;
HttpConnection connection = null;
InputStream is = null;
StringBuffer sb = new StringBuffer();
try {
connection = (HttpConnection)Connector.open("http://localhost:8080/myAppli/j_spring_security_check");
connection.setRequestMethod(HttpConnection.POST);
connection.setRequestProperty("User-Agent", "Profile/MIDP-2.0 Configuration/CLDC-1.1");
connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
os = connection.openOutputStream();
byte data[] =("j_username=appliusername&j_password=applipassword").getBytes();
os.write(data);
os.flush();
int respCode=connection.getResponseCode();
if (connection.getResponseCode() == HttpConnection.HTTP_OK) {
is = connection.openInputStream();
if (is != null ) {
int ch = -1;
while ((ch = is.read()) != -1) {
sb.append((char)ch);
}
}
}else {
System.out.println("Error in opening HTTP Connection. Error#" + respCode);
}
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (is != null) {
is.close();
//is = null;
}
if (os != null) {
os.close();
//is = null;
}
if (connection != null) {
connection.close();
// connection = null;
}
}catch (Exception e2) {
e2.printStackTrace();
}
}
