Question

您好我正在创建一个AFNetworking 3.0 Singleton以在整个应用中使用。

这是我的单身人士

我的ApiClient.h

@interface ApiClient : AFHTTPSessionManager
+ (ApiClient *)sharedInstance;

我的ApiClient.m

+ (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;
}

我的设计有问题。每当我打电话给[Api Client] shareIntance我需要包括

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

例如

- (void)getSingpostContentsOnSuccess:(ApiClientSuccess)success onFailure:(ApiClientFailure)failure {
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"singpost-contents.php"
                                                                              relativeToURL:[NSURL URLWithString:CMS_BASE_URL]]];

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


    NSURLSessionDataTask *dataTask = [ApiClient.sharedInstance dataTaskWithRequest:request completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {
        if (error) {
            NSLog(@"Error: %@", error);
            failure(error);
            //            [self reportAPIIssueURL:[request.URL absoluteString] payload:nil message:[error description]];
        } else {
            NSDictionary *jsonDict  = (NSDictionary *) responseObject;
            success(jsonDict);
        }
    }];
    [dataTask resume];
}

如果不存在，则会出现不可接受的内容类型错误。有多余的？

可以移动吗？

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

启动shareIntance

我尝试使用

减少上面的代码

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

哪个也不起作用

任何帮助或建议都非常感谢！谢谢！
