使用AFNetworking 2.0发布JSON数据

Question

我有一个Web脚本,它通过HTTP POST请求接受JSON字符串作为输入.我遇到了几个相同的AFNetworking 1.x示例,有人可以指点我或给AFNetworking 2.0示例对带有格式化JSON作为输入的Web脚本执行HTTP POST请求吗？

谢谢

Answer 1

在搜索了文档并尝试了一些代码后,我得到了一些例子

 AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.requestSerializer = [AFJSONRequestSerializer serializer];


NSDictionary *params = @ {@"user" :txtUserName, @"pwd" :txtPwd };


[manager POST:URL_SIGNIN parameters:params
success:^(AFHTTPRequestOperation *operation, id responseObject)
{
    NSLog(@"JSON: %@", responseObject);
}
failure:
 ^(AFHTTPRequestOperation *operation, NSError *error) {
     NSLog(@"Error: %@", error);
 }];

另外,不要忘记在服务器脚本中将响应头类型设置为Application/json.

以下是一些用于NSMutableDictionary以JSON格式存储在参数中的POST参数的简单模板.适用于AFNetworking 2.4.1.

NSString *baseURL = @"http://your-server.com/";
NSString *path = @"method/url/";

NSMutableDictionary *parameters = [NSMutableDictionary dictionary];
[parameters setObject:@"value" forKey:@"key"];

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

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

        NSLog(@"JSON: %@", responseObject);
        //here is place for code executed in success case

} failure:^(NSURLSessionDataTask *task, NSError *error) {

        //here is place for code executed in error case
        UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error while sending POST"
                                                            message:@"Sorry, try again."
                                                           delegate:nil
                                                  cancelButtonTitle:@"Ok"
                                                  otherButtonTitles:nil];
        [alertView show];

        NSLog(@"Error: %@", [error localizedDescription]);
}];

如果要将json发布到服务器,则应使用以下方式发布参数.

使用这种方式,您可以在请求标题中找到"Content-Type"是"application/json".

AFJSONRequestSerializer *serializer = [AFJSONRequestSerializer serializer];
[serializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[serializer setValue:@"application/json" forHTTPHeaderField:@"Accept"];
manager.requestSerializer = serializer;

 NSDictionary *paras = @{@"uid" : @(10020)};

[manager POST:@"http://your.request.url" parameters:paras success:^(AFHTTPRequestOperation *operation, id responseObject) {



}failure:^(AFHTTPRequestOperation *operation, NSError *error) {

    NSLog(@"the falire is %@", error);

}];

愿这有帮助.:)

在快速:

添加此内容 manager.AFHTTPRequestOperationManager

manager.requestSerializer = AFJSONRequestSerializer(writingOptions: NSJSONWritingOptions.PrettyPrinted)
