带参数的 Afnetworking 2

Question

我对 IOS 开发真的很陌生..我只想从我的 Web 服务中获得一些 JSON 响应。当我搜索它时，我发现 AFnetworking 对此很有用。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

谁能给我一些代码示例，如何将我的参数传递给该服务以获取 json 响应？

我已经尝试过这段代码.. 但它不会接受参数.. 一些人在谈论 AFHTTPClient.. 但我使用的是 AFN 2.0.. 这里没有类调用 AFHTTPCLient .. 我在这里很容易......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];

我已经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]);
               }
 ];

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：请使用正确的值填写字段并尝试。 dict 是输入后数据

我从 SO question 的某个地方得到了这个。看到这个：

- (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://*.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.. :)

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 3

使用下面的代码

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}];

如果你愿意，你可以设置

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