设置 AFNetworking 3.x 单例请求和响应序列化

Question

您好，我正在使用 AFNetworking 3.x。我已经为网络 api 构建了一个单例

+ (ApiClient *)sharedInstance {
    static ApiClient *sharedInstance = nil;
    static dispatch_once_t oncePredicate;
    dispatch_once(&oncePredicate, ^{
        NSURLSessionConfiguration *sessionConfiguration = [NSURLSessionConfiguration defaultSessionConfiguration];
        sharedInstance = [[self alloc] initWithBaseURL:[NSURL URLWithString:SINGPOST_BASE_URL] sessionConfiguration:sessionConfiguration];

    return sharedInstance;
}

- (id)initWithBaseURL:(NSURL *)url
{
    if ((self = [super initWithBaseURL:url])) {
        AFJSONRequestSerializer *serializer = [AFJSONRequestSerializer serializer];
        [serializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
        [serializer setValue:@"application/json" forHTTPHeaderField:@"Accept"];
    }

    return self;
}

我想在使用单例时设置请求和响应序列化。我们该怎么做呢

我写这些代码不断出错。非常感谢任何帮助。谢谢

[[[ApiClient sharedInstance]requestSerializer = [AFHTTPRequestSerializer] requestWithMethod:POST_METHOD URLString:urlString parameters:xml error:nil]];

我的响应序列化

ApiClient sharedInstance].responseSerializer.acceptableContentTypes = [[ApiClient sharedInstance].responseSerializer.acceptableContentTypes setByAddingObject:@"text/html"];

您需要将您的电话 [AFHTTPRequestSerializer requestWithMethod..] 更改为

[[AFHTTPRequestSerializer serializer] requestWithMethod:POST_METHOD URLString:urlString parameters:xml error:nil];

AFHTTPRequestSerializer 没有类方法requestWithMethod 它需要先创建一个实例，然后调用requestWithMethod

您的代码将如下所示：

[[ApiClient sharedInstance] requestSerializer] = [[AFHTTPRequestSerializer serializer] requestWithMethod:POST_METHOD URLString:urlString parameters:xml error:nil];
