Ios 仅针对特定URL的AFNetworking响应错误

我正在尝试使用GeoNames API获得响应。这是我的密码

  NSMutableDictionary * parameters = [[NSMutableDictionary alloc]initWithDictionary:params];

    NSURL *baseURL = [NSURL URLWithString:@"http://api.geonames.org/findNearbyPostalCodesJSON"];

    AFHTTPSessionManager * manager = [[AFHTTPSessionManager alloc] initWithBaseURL:baseURL];
    manager.responseSerializer = [AFJSONResponseSerializer serializer];

    [manager POST:@"" parameters:parameters success:^(NSURLSessionDataTask * _Nonnull task, id  _Nonnull responseObject) {

        [delegate didReceiveNearByLocationResponse:responseObject];

    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        NSLog(@"%@",error);

    }];

我得到以下错误

Domain=com.alamofire.error.serialization.response code=-1011“请求失败：禁止（403）”UserInfo={NSUnderlyingError=0x7ff013d840f0{error Domain=com.alamofire.error.serialization.response code=-1016”请求失败：不可接受的内容类型：text/html“UserInfo={com.alamofire.serialization.error.response={URL:http://api.geonames.org/findNearbyPostalCodesJSON/ }

我试着用

hurl.it

来检查是否有反应。而且反应很好

令人惊讶的是，我在其他各种请求中使用了上述相同的代码，只是更改了URL，而且这些请求工作正常

已更新

之前它对下面的代码起作用。我做了一些代码质量调整，并将代码转移到上面。然后出现了问题

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

        NSDictionary *params = @{@"lat": lat,
                                 @"lng": lon,
                                 @"username" : @"testing"
                                 };
        [manager POST:@"http://api.geonames.org/findNearbyPostalCodesJSON" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
}

在浏览器中输入URL时，会得到以下JSON：

{"status":{"message":"Please add a username to each call in order for geonames to be able to identify the calling application and count the credits usage.","value":10}}

所以我怀疑，至少，你需要将你的“帖子”改为“获取”：

[manager GET:@"" parameters:parameters success:^(NSURLSessionDataTask * _Nonnull task, id  _Nonnull responseObject) {
    [delegate didReceiveNearByLocationResponse:responseObject];
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
    NSLog(@"%@",error);
}];

除此之外，根据返回的内容，您似乎需要一些附加的应用程序级逻辑来提供用户标识/身份验证，以便获得您感兴趣的实际数据，但上述更改至少应触发对成功块的调用。

“请求失败：不可接受的内容类型：文本/html”
因为AFNetworking只支持@“application/json”@“text/json”@“text/javascript”
您应该添加@“text/html”类型

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




NSMutableDictionary * parameters = [[NSMutableDictionary alloc]initWithDictionary:params];

    NSURL *baseURL = [NSURL URLWithString:@"http://api.geonames.org/findNearbyPostalCodesJSON"];

    AFHTTPSessionManager * manager = [[AFHTTPSessionManager alloc] initWithBaseURL:baseURL];
    manager.responseSerializer = [AFJSONResponseSerializer serializer];

    //insert this code
    [manager.responseSerializer.acceptableContentTypes setByAddingObject:@"text/html"];

    [manager POST:@"" parameters:parameters success:^(NSURLSessionDataTask * _Nonnull task, id  _Nonnull responseObject) {

        [delegate didReceiveNearByLocationResponse:responseObject];

    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        NSLog(@"%@",error);

    }];

我找到了解决方案。我甚至将AFNetworking从2.X升级到了3.0

代码更改如下。特殊更改GET

AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc]initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
manager.requestSerializer = [AFJSONRequestSerializer serializer];

[manager GET:@"http://api.geonames.org/findNearbyPostalCodesJSON" parameters:params progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
    NSLog(@"success!");
    [delegate didReceiveNearByLocationResponse:responseObject];
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
    NSLog(@"error: %@", error);
}];

它不起作用。：（顺便说一句，我更新了这个问题。因为它以前工作得很好
