AFNetworking 2.xx中的AFJSONParameterEncoding
我正在实现以下paypal REST API:
curl -v https://api.sandbox.paypal.com/v1/vault/credit-card \ -H 'Content-Type:application/json' \ -H 'Authorization: Bearer {accessToken}' \ -d '{ "payer_id":"user12345", "type":"visa", "number":"4417119669820331", "expire_month":"11", "expire_year":"2018", "first_name":"Joe", "last_name":"Shopper" }'
我已经使用以下代码在AFNetworking 1.3.3中成功实现了这个api。 其中PPWebService
是PPWebService
的子类
[[PPWebService sharedClient] setParameterEncoding:AFJSONParameterEncoding]; [[PPWebService sharedClient] setDefaultHeader:@"Content-Type" value:@"application/json"]; [[PPWebService sharedClient] setDefaultHeader:@"Authorization" value:[NSString stringWithFormat:@"Bearer %@", accessToken]]; [[PPWebService sharedClient] postPath:@"vault/credit-card" parameters:creditCard success:^(AFHTTPRequestOperation *operation, id responseObject) { NSDictionary *response = [self JSONToObject:operation.responseString]; creditCardId = response[@"id"]; if(creditCardId) { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Credit card" message:@"Saved !!" delegate:nil cancelButtonTitle:@"on" otherButtonTitles:nil]; [alert show]; } } failure:^(AFHTTPRequestOperation *operation, NSError *error) { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Credit card" message:error.description delegate:nil cancelButtonTitle:@"on" otherButtonTitles:nil]; [alert show]; }];
我想在我的项目中使用AFNetworking 2.xx。 但我无法使用这个新版本。
我有子类AFHTTPRequestOperationManager
。 我搜索互联网,人们建议我使用AFJSONRequestSerializer
。 所有其他代码非常相似。 但是我也得到了错误的请求错误。
那么如何在AFNetworking 2.xx中使用POST方法发送原始JSON字符串?
编辑
AFNetworking 2.XX代码
错误状态 :404错误请求
回应 :
{"name":"MALFORMED_REQUEST","message":"The request JSON is not well formed.","information_link":"https://developer.paypal.com/docs/api/#MALFORMED_REQUEST","debug_id":"ab3c1dd874a07"}
我正在通过使用Postman获得正确的响应,如下面的屏幕截图所示。
所以最后我得到了答案。 我使用AFHTTPSessionManager
子类在我的项目中实现API。 并将其与singleton对象一起使用。 所以这是我的单身方法。
+ (MASWebService *)APIClient { static MASWebService *_sharedClient = nil; static dispatch_once_t onceToken; dispatch_once(&onceToken, ^ { NSURL *baseURL = [NSURL URLWithString:BaseURL]; NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration]; _sharedClient = [[MASWebService alloc] initWithBaseURL:baseURL sessionConfiguration:config]; _sharedClient.responseSerializer = [AFJSONResponseSerializer serializerWithReadingOptions:NSJSONReadingAllowFragments]; _sharedClient.requestSerializer = [AFJSONRequestSerializer serializer]; [_sharedClient.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; }); return _sharedClient; }
主要关键是将Request Serializer HTTP Header“Content-Type”设置为“application / json”
如果您没有将AFHTTPRequestOperationManager
子类AFHTTPSessionManager
并使用AFHTTPRequestOperationManager
进行单个请求,那么它也可以工作,因为AFHTTPRequestOperationManager
也符合AFURLRequestSerialization
协议作为AFHTTPRequestSerializer
属性。 我还没有这样做,但看起来应该是这样的。
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; NSDictionary *parameters = @{@"foo": @"bar"}; manager.responseSerializer = [AFJSONResponseSerializer serializerWithReadingOptions:NSJSONReadingAllowFragments]; manager.requestSerializer = [AFJSONRequestSerializer serializer]; [manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; [manager POST:@"http://example.com/resources.json" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) { NSLog(@"JSON: %@", responseObject); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"Error: %@", error); }];
我希望这会奏效。 如果我在某处错了,请通知我。

那么如何在AFNetworking 2.xx中使用POST方法发送原始JSON字符串?
尝试在AFHTTPRequestOperationManager中使用SOAP + XML数据时遇到了同样的问题。 显然,请求序列化程序应该是子类,以满足您的特殊序列化需求,但这种方式似乎更容易:
NSError *error = nil; NSData *envelopeData = [NSJSONSerialization dataWithJSONObject:params options:options error:nil]; NSMutableURLRequest *request = [self.requestSerializer requestWithMethod:@"POST" URLString:path parameters:nil error:&error]; // In my case, I also needed the following: // [request setValue:action forHTTPHeaderField:@"SOAPAction"]; [request setHTTPBody:envelopeData]; AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] init]; operation = [self HTTPRequestOperationWithRequest:request success:^(AFHTTPRequestOperation *operation, id responseObject) { // parse response here } failure:^(AFHTTPRequestOperation *operation, NSError *error) { // parse response here }];
它劫持了AFHTTPRequestOperationManager创建的请求序列化程序,将参数数据插入HTTP正文,然后将此新请求传递给AFHTTPRequestOperation。
