AFHTTPSessionManager 子类：带有正文的发布 API。

Question

我想出了如何使用 AFnetworking 传递参数，但我很难弄清楚如何将正文作为我的 API 调用的一部分传递。目前这就是我所做的：

    - (void)authenticateUser:(NSString *)username
                password:(NSString *)password
                success:(void (^) (NSString *accessToken))success
                failure:(RequestFailureBlock)failure
{
    NSString *authURL = @"http://someurlforauthentication";
    NSDictionary *parameters = @{@"username" : username,
                                 @"password" : password };

    [self.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];




    [self POST:authURL parameters:parameters success:^(NSURLSessionDataTask *task, id responseObject){

        NSString *accessToken = responseObject[@"access_token"];

        // Store Access Token
        NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
        [defaults setObject:accessToken forKey:APIAuthorizationToken];
        [defaults synchronize];

        NSLog(@"Hello %@", accessToken);

        success(accessToken);

    } failure:failure];
}

我需要做的不是传递任何参数，而是传递一个带有包含登录凭据的 json 字符串的正文。像这样的

 AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];

// Body

const char bytes[43] = "{\n \"username\": \"max\",\n \"password\": \"pass\"\n}";
request.HTTPBody = [NSData dataWithBytes:bytes length:43];

提前致谢。

使用 AFJSONRequestSerializer 和 AFJSONResponseSerializer 你可以做你想做的事。然后只需使用您用于发布的代码即可。整个过程应该如下所示：

NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];

AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc] initWithSessionConfiguration:configuration];
    [manager setRequestSerializer:[AFJSONRequestSerializer serializer]];
    [manager setResponseSerializer:[AFJSONResponseSerializer serializer]];

    NSDictionary *parameters = @{@"test": @"this is a test"};

    [manager POST:@"http://localhost:8080/TestRequest/test" parameters:parameters success:^(NSURLSessionDataTask *task, id responseObject) {

        NSLog(@"%@",[responseObject description]);

    } failure:^(NSURLSessionDataTask *task, NSError *error) {

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