Question

我正在尝试使用RestKit进行基本身份验证，但我需要一些帮助来弄清楚为什么我会获得状态代码401（未经授权）。我试过了this，但它对我不起作用。如果有人可以指出我的错误，我将不胜感激。

这就是我的数据在服务器端的样子：样品

{
  "Id": "baec6f47",
  "TokenValidity": "00:00:00.1234567",
  "ValidTo": "2013-10-28T23:54:21.2934278+00:00",
  "Parameters": {},
  "Token": "sample string 3"
}

我有一个名为TokenObject的NSObject类，我需要存储这些数据。

TokenObject.h

#import <Foundation/Foundation.h>

@interface TokenObject : NSObject
@property (nonatomic,strong) NSNumber *tokenId;
@property (nonatomic,strong) NSDate *TokenValidity;
@property (nonatomic,strong) NSDate *ValidTo;
@property (nonatomic,strong)NSString *Parameters;
@property (nonatomic,strong)NSString *Token;

@end

快速概述：

在登录屏幕中，我只询问用户名，一旦用户点击注册，我发送了一个Post请求来创建帐户并发送令牌的get请求（并在获取之前使用RestKit的setAuthorizationHeaderWithUsername）请求）。对于用户名：密码，我使用的是昵称和硬件ID。

这是我发布帐户（工作）的方法，将用户名和密码编码为base 64（有效）并尝试获取令牌（这是我遇到问题的部分）。

Answer 1

从上次评论开始，这一行：

[manager2.HTTPClient setAuthorizationHeaderWithUsername:@"encodedName" password:@"encodedHardwareId"];

是问题，因为您实际上没有传递encodedName和encodedHardwareId变量，而是传递2个常量字符串。所以它应该是：

[manager2.HTTPClient setAuthorizationHeaderWithUsername:encodedName password:encodedHardwareId];

使用Restkit进行基本认证
