如何使用AFNetworking发布JSON参数？

Question

我怎么能POST JSON参数AFNetworking？以下是示例JSON格式.先感谢您.

{
    "application": {
        "identifier": "appDev"
    },
    "sso": {
        "version": 2.0,
        "session_expiry": 43200
    },
    "user": {
        "password": "xxxx~!@",
        "username": "xxx0min"
    },
    "coordinate": {
        "latitude": 10.9948629,
        "longitude": -169.5213749
    }
}

我成功创建了一个JSON:

NSDictionary *parameters = @{@"application": @{@"identifier": @"appDev"}, @"sso": @{@"version": @"2.0", @"session_expiry":@43200}, @"user": @{@"password":@"xxxx~!@", @"username":@"xxx0min"}, @"coordinate": @{@"latitude":@10.9948629, @"longitude":@-169.5213749}};

首先将JSON字符串转换为NSDictionary:

NSError *error;
NSData *objectData = [@"{\"1\":\"2\"}" dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:objectData
                                      options:NSJSONReadingMutableContainers 
                                        error:&error];

然后你可以用AFNetworking发送这本字典.在版本3中,您应该使用AFHTTPSessionManager:

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

[manager POST:@"your_URL" parameters:json progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
    NSLog(@"Complete");
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
    NSLog(@"Fail");
}];
