如何传递授权令牌头像目标c？

Question

我正在传递用户名，API调用的密码，它会返回正确的值。但是，在认证API返回安全令牌后，我需要捕获令牌并传递用户名和密码。我也是这样做的，但它返回禁止的错误，它表示无效的令牌错误。我还尝试使用base64来传递令牌，如答案stackoverflow.The代码，我用它来通过下面

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url]; 
[request setHTTPMethod:[self HTTPMethod]]; 
[request setHTTPBody:self.requestData]; 
[request addValue:@"xyz" forHTTPHeaderField:@"username"]; 
[request addValue:@"xyz" forHTTPHeaderField:@"password"]; 
[request addValue:[[NSUserDefaults standardUserDefaults]valueForKey:@"Auth"] forHTTPHeaderField:@"Authorization"]; 
[request addValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; 

我搜索头方法标头值，但没有什么helps.what我做错了here.pls人帮助我解决it.Thanks。

使用setValue为请求而不是addValue因为addValue如果值指定字段被预先设定，所提供的值是用适当的字段分隔符

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url]; 
[request setHTTPMethod:[self HTTPMethod]]; 
[request setHTTPBody:self.requestData]; 
[request setValue:@"xyz" forHTTPHeaderField:@"username"]; 
[request setValue:@"xyz" forHTTPHeaderField:@"password"]; 
[request setValue:[[NSUserDefaults standardUserDefaults]valueForKey:@"Auth"] forHTTPHeaderField:@"Authorization"]; 
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; 

检查苹果文档 - 追加到现有值
