如何在Objective C中使用与AFNetworking一起使用的GET REST方法

Question

我正在尝试从我的服务器获取 JSON，但我需要将一些参数传递给 url。我不想将这些参数添加到 URL，因为它们包含 Content-Type、DeviceType、DeviceID 和 Authorization。

对于一个简单的 URL 请求，我有以下代码，但响应为空，请告诉我这段代码有什么问题？

常数.h

#define KSERVER_URL  @"http://101.127.236.85:6067/tmsservice/MobileService.svc/"

#define KAppInfo_URL @"AuthenticateEmployee"

-(void)loginRequestContentType:(NSString*) content deviceType:(NSString*) deviceT deviceID:(NSString*) devId Authorization:(NSString*) auth WithResponse: (void (^)(id responseObject, NSError *error))responseAndErr {
NSString *urlString = [NSString stringWithFormat:@"%@%@",KSERVER_URL,KAppInfo_URL];

NSLog(@"URL = %@", urlString);
NSMutableDictionary *parameters = [[NSMutableDictionary alloc] init];

[parameters setValue:@"application/json" forKey:@"Content-Type"];
[parameters setValue:@"iOS" forKey:@"DeviceType"];
[parameters setValue:@"123456" forKey:@"DeviceID"];
[parameters setValue:strGlobalfinalString forKey:@"Authorization"];

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer.acceptableContentTypes = [manager.responseSerializer.acceptableContentTypes setByAddingObject:@"text/html"];

[manager GET:urlString parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
    responseAndErr(responseObject, Nil);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    responseAndErr(Nil, error);
}];

}

登录.m

-(void)sendLoginRequest {
    MBProgressHUD *progressIndicator = [MBProgressHUD showHUDAddedTo:self.navigationController.view animated:YES];
    progressIndicator.labelText = kLoadingTitle;
    progressIndicator.detailsLabelText = kPleaseWaitText;

    NSString *userEmail = self.userNameTextField.text;
    NSString *userPassword = self.passwordTextField.text;

    NSLog(@"Email =  %@", userEmail);
    NSLog(@"Password =  %@", userPassword);

    NSString *singleString = [NSString stringWithFormat: @"%@:%@", userEmail,userPassword];
    NSLog(@" Login Single String = %@", singleString);

    NSData *nsdata = [singleString dataUsingEncoding:NSUTF8StringEncoding];
    // Get NSString from NSData object in Base64
    NSString *base64Encoded = [nsdata base64EncodedStringWithOptions:0];

    // Print the Base64 encoded string
    NSLog(@"Login Encoded: %@", base64Encoded);


    strGlobalfinalString= [NSString stringWithFormat:@"Basic %@",base64Encoded];


    NSLog(@"Login Final Encoded String: %@", strGlobalfinalString);

    [[NetwokManager sharedInstance] loginRequestContentType:@"application/json" deviceType:@"iOS" deviceID:@"123456" Authorization:strGlobalfinalString  WithResponse:^(id responseObject, NSError *error)

     {
         [progressIndicator hide:YES];

         if (!error) {

             NSLog(@"responseString = %@", responseObject);
             HomeViewController *controller = [self.storyboard instantiateViewControllerWithIdentifier:@"HomeViewController"];
             [self.navigationController pushViewController:controller animated:YES];
             if (responseObject == nil)
             {
                 NSLog(@"No data from server");
                 [self showAlertViewWithMessage:@"No data downloaded from server!"];
             }

             NSDictionary *resposneDict = (NSDictionary*)responseObject;
             NSLog(@"New Dictionary Data = %@", resposneDict);


             NSString *msg;
             msg = [resposneDict objectForKey:@"status"];
             if ([msg isEqualToString:@"success"])
             {


                 HomeViewController *controller = [self.storyboard instantiateViewControllerWithIdentifier:@"HomeViewController"];
                 [self.navigationController pushViewController:controller animated:YES];


             }
             else if ([resposneDict objectForKey:@"StatusMessage"])
             {
                 [self showAlertViewWithMessage:@"Invalid credentials, please check your credentials"];
             }
         }
     }];
}

将 AFNetworking 更新到 3.0 或更高版本并尝试以下操作：

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
NSDictionary *parameters = @{@"userid":userId, @"x-session": session};
NSString *urlString = @"http://api.example.com/sampleLink";
[manager GET:urlString parameters:parameters progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
    NSLog(@"%@", responseObject);

} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
    NSLog(@"%@", [error localizedDescription]);
}];
