ios - NSURLRequest 未将值发布到 Codeigniter API

早安，

我正在尝试使用基于 Codeigniter 的 API 来连接 iOS 并使用 NSURLRequest。 API 处于 Debug模式，现在它返回与您发布的 json 相同的键值对。我尝试通过 postman 将值发布到链接并且它工作正常，但是当我通过我的 iOS 应用程序发布它时，收到了 json 响应，但应该包含发布值的数组是空的。

这是 iOS 代码片段:

NSURL *url = [NSURL URLWithString:[NSString stringWithFormat"%@%@",BASEURL,service]];

NSMutableURLRequest * request = [NSMutableURLRequest requestWithURL:url];

NSURLConnection *connection=[[NSURLConnection alloc] initWithRequest:request delegate:self];

NSString * params = @"authkey=waris";
NSData * postData = [params dataUsingEncoding:NSUTF8StringEncoding];

NSString *postLength = [NSString stringWithFormat"%lu",(unsigned long)[postData length]];

[request setValue:postLength forHTTPHeaderField"Content-Length"];
[request setValue"application/x-www-form-urlencoded" forHTTPHeaderField"content-type"];;
[request setHTTPMethod"OST"];
[request setHTTPBody:postData];

NSLog(@"osting : '%@'  to %@",params,url);

[connection start];

这是我通过 postman (A RESTFUL Client for Chrome)发布相同参数时的响应

{
"status": "1",
"data": {
    "authkey": "warisali"
  }
}

但是，当我从上面的 iOS 代码中查询相同的 API 时，我得到了这个:

{
  data = 0;
  status = 1;
}

对此事的任何帮助将不胜感激!

我有同样的问题(不是 CodeIgniter 而是 Ruby ...) 试试这样，解决了我的问题。

NSURL *url = [NSURL URLWithString:[NSString stringWithFormat"%@%@",BASEURL,service]];

NSMutableURLRequest * request = [NSMutableURLRequest requestWithURL:url];

NSURLConnection *connection=[[NSURLConnection alloc] initWithRequest:request delegate:self];

NSDictionary *paramDict = @{@"authkey": @"waris"};
NSError *error = nil;
NSData *postData = [NSJSONSerialization dataWithJSONObject:paramDict options:NSJSONWritingPrettyPrinted error:&error];

if (error)
{
    NSLog(@"error while creating data %@", error);
    return;
}

    NSString *postLength = [NSString stringWithFormat"%lu",(unsigned long)[postData length]];

[request setValue:postLength forHTTPHeaderField"Content-Length"];
[request setValue"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];;
[request setHTTPMethod:@"OST"];
[request setHTTPBody:postData];

NSLog(@"osting : '%@'  to %@",params,url);

[connection start];
