AFNetworking 2.x.x中的AFJSONParameterEncoding [英] AFJSONParameterEncoding in AFNetworking 2.x.x

问题描述

我正在实现以下Paypal REST API:

I am implementing following 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"
}'

我已使用以下代码在AFNetworking 1.3.3中成功实现了此api.其中PPWebService是AFHTTPClient

I have successfully implement this api in AFNetworking 1.3.3 with following Code. Where PPWebService is subclass of AFHTTPClient

[[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AFNetworking2.x.x.但是我不能用这个新版本来做.

I want to use AFNetworking 2.x.x in my project. But I am not able to do it with this new version.

我有子类AFHTTPRequestOperationManager.我在互联网上搜索，有人建议我使用AFJSONRequestSerializer.所有其他代码非常相似.但比起我我得到错误的请求错误.

I have subclass AFHTTPRequestOperationManager. I search internet and people suggest me to use AFJSONRequestSerializer. All other code is very similar. But than also I am getting bad request error.

那么如何在AFNetworking 2.x.x中使用POST方法发送原始JSON字符串?

So how can I send raw JSON string in with POST method in AFNetworking 2.x.x?

编辑

AFNetworking 2.X.X的代码

错误状态:404错误请求

响应:

{"name":"MALFORMED_REQUEST","message":"The request JSON is not well formed.","information_link":"https://developer.paypal.com/docs/api/#MALFORMED_REQUEST","debug_id":"ab3c1dd874a07"}

使用Postman可以得到正确的响应，如以下屏幕截图所示.

I am getting proper response by using Postman as shown in following screenshot.

推荐答案

所以最后我得到了答案.我使用AFHTTPSessionManager的子类在我的项目中实现API.并将其与单例对象一起使用.这就是我的单例方法.

So finally I got answer. I use subclass of AFHTTPSessionManager to implement API in my project. And use it with singleton object. So this is my singleton method.

+ (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;
}

主线将请求序列化程序" HTTP标头"Content-Type"设置为"application/json"

The main key line is setting Request Serializer HTTP Header "Content-Type" to "application/json"

如果您没有将AFHTTPSessionManager子类化并且对单个请求使用AFHTTPRequestOperationManager，那么它也将起作用，因为AFHTTPRequestOperationManager也是AFHTTPRequestSerializer的属性，也符合AFURLRequestSerialization协议.我还没有做，但是应该看起来像这样.

If you are not subclassing AFHTTPSessionManager and using AFHTTPRequestOperationManager for single request than also it will work because AFHTTPRequestOperationManager is also conform to AFURLRequestSerialization protocol as property of AFHTTPRequestSerializer. I have not done it but it should look like this.

    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);
    }];

我希望这会起作用.如果我在某个地方错了，请在评论中通知我.

I hope this will work. Inform me in comment if I am wrong somewhere.
