我有一个 java webservice,有一些方法。
网络服务方法采用这种形式:
@Webservice(paramNames = {"email", "password", "stayLogged", "idClient"},
public Response startSession(String email, String password, Boolean stayLogged, String idClient) throws Exception {
boolean rC = stayLogged != null && stayLogged.booleanValue();
UserService us = new UserService();
User u = us.getUsersernamePassword(email, password);
if (u == null || u.getActive() != null && !u.getActive().booleanValue()) {
return ErrorResponse.getAccessDenied(id, logger);
}
InfoSession is = null;
String newKey = null;
while (newKey == null) {
newKey = UserService.md5(Math.random() + " " + new Date().getTime());
if (SessionManager.get(newKey) != null) {
newKey = null;
} else {
is = new InfoSession(u, rC, newKey);
if (idClient != null && idClient.toUpperCase().equals("ANDROID")) {
is.setClient("ANDROID");
}
SessionManager.add(newKey, is);
}
}
logger.log(Level.INFO, "New session started: " + newKey + " - User: " + u.getEmail());
return new Response(new InfoSessionJson(newKey, is), null, id);
}
webservice可以接收json-rpc调用,客户端代码可以调用webservice的方法,在iOS中有这样的形式:
-(void)asynchronousRPCWithMethod:(NSString *)method andParams:(NSArray *)params{
NSLog(@"REMOTE PROCEDURE CALL ON %@", method);
self.rpcMethod = method;
NSMutableString *requestString = [[NSMutableString alloc] init];
//setting method
[requestString appendFormat:@"{\"method\":\"%@\"", method];
//setting params
[requestString appendString:@", \"params\":["];
int max = [params count];
int c = 0;
for (NSString *str in params){
c++;
[requestString appendFormat:@"\"%@\"", str];
if (c==max){
}
else{
[requestString appendString:@", "];
}
}
[requestString appendFormat:@"], \"id\":1}"];
NSLog(@"Request:\n%@", requestString);
NSData *requestData = [NSData dataWithBytes:[requestString UTF8String] length:[requestString length]];
[requestString release];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:WEBSITELINK]] autorelease];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:requestData];
NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:request delegate:self startImmediately:NO];
[conn scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSRunLoopCommonModes];
[conn start];
UIApplication *app = [UIApplication sharedApplication];
app.networkActivityIndicatorVisible = YES;
if (conn) {
NSMutableData *data = [[NSMutableData alloc] init];
self.receivedData = data;
[data release];
}
else {
NSError *error = [NSError errorWithDomain:RPCErrorDomain
code:RPCErrorNoConnection
userInfo:nil];
NSLog(@"*** error ***\n%@", error);
/**
* SENT A MESSAGE WITH A ERROR
*/
if ([self.delegate respondsToSelector:@selector(rpcDidFailWithError:)])
[delegate rpcDidFailWithError:error];
}
}
如何在 Android 上实现相同的客户端方法???
