如何使用身份验证从服务器获取JSON数据？

我的JSON在服务器上，假设我的网址是如何使用身份验证从服务器获取JSON数据？

https://abc.companyname.com/posts/list/10

当我粘贴URL在浏览，它要求我用户名和密码。当我输入这些证书时，它会返回一些JSON格式的数据，如下所示。

[{"id":"5","picture":"myimage.jpg","name":"Usman Zafar","type":"textonly","message":"Woo this is demo and it looks good thanks adeco","image":null,"video_id":null,"datecreated":"2013-10-17 10:14:02","totalLikes":0,"totalComments":0,"commentsData":null}, 


{"id":"6","picture":"default.jpg","name":"Usman Zafar","type":"textonly","message":"Hello this is the demo of another post but no image","image":null,"video_id":null,"datecreated":"2013-10-17 10:31:04","totalLikes":0,"totalComments":0,"commentsData":null}, 


{"id":"7","picture":"default.jpg","name":"Usman Zafar","type":"textonly","message":"Hello this is the demo of another post but no image","image":null,"video_id":null,"datecreated":"2013-10-17 10:31:24","totalLikes":0,"totalComments":0,"commentsData":null}, 


{"id":"11","picture":"myimage_9.jpg","message":"Regukar Text comments no.772"}]}]

我问题是

如何在iPhone编程认证（用户名+密码）创建NSURLConnection的？

如果需要关于问题的任何其他数据，请通过评论让我知道。

谢谢

我看到的是，它使用的NSMutableString，其中因为我没有这样的对象。 – Duaan

NSMutableString是一个可变字符串，也就是可以编辑其内容的字符串。你可以从你的字符串中创建NSMutableString。 Ex NSMutableString * newString = [[NSMutableString alloc] initWithString：@“yourString”]; – Priyatham51

这是更多的应用程序设计。首先，通过向用户显示一些UI屏幕来捕获用户名和密码，然后您需要将数据发送到服务器。你可以将普通的键值对转换成NSData。

看看下面的一段代码开始。

self.URLRequest = [NSMutableURLRequest requestWithURL:self.URL cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:999]; 
[self.URLRequest setHTTPMethod:[self methodStringForMethod:self.requestMethod]]; 
    for (NSString *aHeaderKey in self.requestHeader) { 
     [self.URLRequest setValue:[self.requestHeader valueForKey:aHeaderKey] forHTTPHeaderField:aHeaderKey]; 
    } 

    if (self.requestHeader) { 
     [self.URLRequest setValue:@"gzip" forHTTPHeaderField:@"Accept-Encoding"]; 
    } 

    if (self.body) { 
     [self.URLRequest setHTTPBody:[self keyValuePostDataFromDictionary:self.body]]; 
    } 

    if (self.connection) { 
     [self.connection cancel]; 
     self.connection = nil; 
    } 
self.connection = [[NSURLConnection alloc] initWithRequest:self.URLRequest delegate:self];

使用下面的代码：

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:fileURL]; 
[request setCachePolicy:NSURLRequestReloadIgnoringLocalCacheData]; 

NSURLResponse *response = nil; 
NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:error];
