使用AFNetworking 2.0 请求数据时出现错误 Request failed: unacceptable content-type: text/html 解决方法

添加一行

manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];

即可

整个代码为：

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];
    NSDictionary *parameters = @{@"foo":@"bar"};
    [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);
    }];
