如何在iOS中嵌套两个键以进行API调用

这是我如何发布到API的：

curl-v-H'内容类型：application/json'-H'接受：application/json'-X POSThttp://sub.domain.com/api/v1/sections.json -d“{\”节\“：{\”属性\“：{\”电子邮件\“：\”example@email.com\“，”部门“：”dpt123“，”电话号码“：”55578912“}}}}}”

我尝试使用以下代码来实现这一点：

NSString *strurl=@"http://sub.domain.com/api/v1/sections.json";
NSURL *url=[NSURL URLWithString:[strurl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSMutableDictionary *dict=[[NSMutableDictionary alloc] init];


[dict setValue:phoneTxt.text forKey:@"phone_number"];
[dict setValue:emailTxt.text forKey:@"email"];
[dict setValue:departmentTxt.text forKey:@"department"];
ASIFormDataRequest *request=[ASIFormDataRequest requestWithURL:url];


NSDictionary *sectionDic = [NSDictionary dictionaryWithObjectsAndKeys:dict, @"properties", nil];

NSDictionary *dic = [NSDictionary dictionaryWithObjectsAndKeys:sectionDic, @"section",nil];

SBJsonWriter *jsonWriter = [[SBJsonWriter alloc] init];
NSString *params = [jsonWriter stringWithObject:dic];

NSLog(@"param----%@",params);
[request setPostValue:params forKey:@"properties"];


[request setRequestMethod:@"POST"];
[request setDelegate:self];
[request startAsynchronous];

但我得到的答复如下：

参数：

{“section”=>“{\“properties\”：{\“department\”：“dpt123\”，“email\”：\”example@email.com\“，”电话号码“：\”55578912\“}}}}

它给我这个错误，因为它的属性是字符串：

NoMethodError（未定义的方法“stringify#keys”用于#）

如何使用节和属性作为键发布。非常感谢您的帮助。

您调用了错误的方法来创建字典

sectionDic

和

dic

dictionaryWithObjectsAndKeys:

希望对象和键都使用数组。相反，尝试

NSDictionary *sectionDic = @{@"properties": dict};
NSDictionary *dic = @{@"section":sectionDic};
