Question

我是IOS开发的新手。我只想从我的网络服务获得一些JSON响应。当我搜索它时，我发现AFnetworking对此有好处。所以我下载了它并做了一个示例应用程序。但我需要将一些参数传递给服务。我的服务有两个参数[用户名和密码]。我的网址是这样的

http://myweb.mobile.com/WebServices/AppointmentService.asmx/GetValidUser

任何人都可以给我一些代码示例如何将我的参数传递给此服务以获取json响应吗？

我已经尝试过这段代码..但它不会带参数..有些人告诉AFHTTPClient ..但即时通讯使用AFN 2.0 ..这里没有课程调用AFHTTPCLient ..我在这里有所帮助....请帮帮我

 NSURL *url = [NSURL URLWithString:@"https://maps.googleapis.com/maps/api/place/textsearch/json?query=restuarants+in+sydney&sensor=false&key=AIzaSyDn9a-EvJ875yMxZeINmUP7CwbO9YT1w2s"];
NSURLRequest *request = [NSURLRequest requestWithURL:url];

// 2
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
operation.responseSerializer = [AFJSONResponseSerializer serializer];

[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {

    // 3
    self.googlePlaces = [responseObject objectForKey:@"results"];

    [self.tableView reloadData];
  //  NSLog(@"JSON RESULT %@", responseObject);

   self.weather = (NSDictionary *)responseObject;
    self.title = @"JSON Retrieved";
    [self.tableView reloadData];


} failure:^(AFHTTPRequestOperation *operation, NSError *error) {

    // 4
    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error Retrieving Weather"
                                                        message:[error localizedDescription]
                                                       delegate:nil
                                              cancelButtonTitle:@"Ok"
                                              otherButtonTitles:nil];
    [alertView show];
}];

// 5
[operation start];

编辑：

我使用下面的代码段解决了我的问题...

 NSDictionary *parameters = [[NSDictionary alloc] initWithObjectsAndKeys:@"47", @"caregiverPersonId", nil];

AFSecurityPolicy *policy = [[AFSecurityPolicy alloc] init];
[policy setAllowInvalidCertificates:YES];

AFHTTPRequestOperationManager *operationManager = [AFHTTPRequestOperationManager manager];
[operationManager setSecurityPolicy:policy];
operationManager.requestSerializer = [AFJSONRequestSerializer serializer];
operationManager.responseSerializer = [AFJSONResponseSerializer serializer];

[operationManager POST:@"your full url goes here"
            parameters:parameters
               success:^(AFHTTPRequestOperation *operation, id responseObject) {
                   NSLog(@"JSON: %@", [responseObject description]);
               }
               failure:^(AFHTTPRequestOperation *operation, NSError *error) {
                   NSLog(@"Error: %@", [error description]);
               }
 ];

Answer 1

我从问题的某个地方得到了这个。见：

- (IBAction)loginButtonPressed {        

    NSURL *baseURL = [NSURL URLWithString:@"http://myweb.mobile.com/WebServices/AppointmentService.asmx"];

    //build normal NSMutableURLRequest objects
    //make sure to setHTTPMethod to "POST". 
    //from https://github.com/AFNetworking/AFNetworking
    AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:baseURL];
    [httpClient defaultValueForHeader:@"Accept"];

    NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
                            [usernameTextField text], kUsernameField, 
                            [passwordTextField text], kPasswordField, 
                            nil];

    NSMutableURLRequest *request = [httpClient requestWithMethod:@"POST" 
          path:@"http://myweb.mobile.com/WebServices/AppointmentService.asmx/GetValidUser" parameters:params];

    //Add your request object to an AFHTTPRequestOperation
    AFHTTPRequestOperation *operation = [[[AFHTTPRequestOperation alloc] 
                                      initWithRequest:request] autorelease];

    //"Why don't I get JSON / XML / Property List in my HTTP client callbacks?"
    //see: https://github.com/AFNetworking/AFNetworking/wiki/AFNetworking-FAQ
    //mattt's suggestion http://stackoverflow.com/a/9931815/1004227 -
    //-still didn't prevent me from receiving plist data
    //[httpClient registerHTTPOperationClass:
    //         [AFPropertyListParameterEncoding class]];

    [httpClient registerHTTPOperationClass:[AFHTTPRequestOperation class]];

    [operation setCompletionBlockWithSuccess:
      ^(AFHTTPRequestOperation *operation, 
      id responseObject) {
        NSString *response = [operation responseString];
        NSLog(@"response: [%@]",response);
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"error: %@", [operation error]);
    }];

    //call start on your request operation
    [operation start];
    [httpClient release];
}

希望这会有所帮助.. :)

修改

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; [manager POST:URLString parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { [formData appendPartWithFormData:[email dataUsingEncoding:NSUTF8StringEncoding] name:@"email"]; [formData appendPartWithFormData:[pass dataUsingEncoding:NSUTF8StringEncoding] name:@"password"]; // etc. } success:^(AFHTTPRequestOperation *operation, id responseObject) { NSLog(@"Response: %@", responseObject); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"Error: %@", error); }];

Answer 2

试试这个

-(void)login
{
    NSMutableDictionary *dict=[[NSMutableDictionary alloc]initWithCapacity:3];
    [dict setObject:_usernameTextField.text forKey:@"userName"];
    [dict setObject:_passwordTextField.text forKey:@"password"];


    AFHTTPClient *client=[[AFHTTPClient alloc]initWithBaseURL:[NSURL URLWithString:@""]];

    [client registerHTTPOperationClass:[AFJSONRequestOperation class]];
    [client setDefaultHeader:@"Accept" value:@"application/json"];
    client.parameterEncoding = AFJSONParameterEncoding;

    [client postPath:@"GetValidUser" parameters:dict success:^(AFHTTPRequestOperation *operation, id responseObject)
     {
         NSDictionary *op=(NSDictionary *)responseObject;
         NSLog(@"%@",op);

    }
             failure:^(AFHTTPRequestOperation *operation, NSError *error) {

                     UIAlertView *alert=[[UIAlertView alloc]initWithTitle:MESSAGE_EN message:@"Unable to login. Please try again." delegate:self cancelButtonTitle:OK_EN otherButtonTitles:nil, nil];
                     [alert show];

                     NSLog(@"error.localizedDescription %@",error.localizedDescription);
                              }];

}

注意：请填写适当值的字段并尝试。 dict是输入postdata

Answer 3

使用以下代码

NSDictionary *paramDictionary = [NSDictionary dictionaryWithObjectsAndKeys:@"first_Object",@"first_Key",@"second_Object",@"second_Key" nil];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager POST:@"YOUR_URL_STRING" parameters:paramDictionary success:^(AFHTTPRequestOperation *operation, id responseObject) {Success responce} failure:^(AFHTTPRequestOperation *operation, NSError *error) {failure responce}];

如果您愿意，可以设置

manager.responseSerializer = [AFJSONResponseSerializer serializer];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
manager.securityPolicy.allowInvalidCertificates = YES;

Afnetworking 2带参数
