如何使用AFNetworking发布JSON参数？ [英] How To POST JSON Parameters Using AFNetworking?

问题描述

如何 POST JSON 参数 AFNetworking ？下面是示例 JSON 格式。提前谢谢。

how can I POST JSON parameters with AFNetworking? Below is the example JSON format. Thank you in advance.

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

I成功创建了一个JSON：

I successfully created a 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}};

推荐答案

首先将JSON字符串转换为NSDictionary：

First convert JSON string to 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：

Then you can send this dictionary with AFNetworking. In version 3 you should use 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");
}];
