ios - 如何实现自定义 AWSCredentialsProvider

Question

我有从服务器生成的凭据和 token 。我使用了 AWSStaticCredentialsProvider，而我需要传递 token 以进行身份​​验证。

引用了很多链接，但除了凭据提供程序的自定义实现的想法之外没有进一步的帮助。任何代码都会有帮助。

Answer 1

1.新建一个继承自NSObject的类；
2.确保它实现了AWSCredentialsProvider；
3.声明所需的属性，如Access、Secret和Token以及初始化方法；
4.然后在实现文件中实现声明的方法。

代码片段:

.h文件

@interface CustomCredentialsProvider : NSObject<AWSCredentialsProvider>
@property (nonatomic, readonly) NSString *accessKey;
@property (nonatomic, readonly) NSString *secretKey;
@property (nonatomic, readonly) NSString *sessionKey;

+ (instancetype)credentialsWithAccessKey:(NSString *)accessKey
                               secretKey:(NSString *)secretKey sessionKey:(NSString*)sessionKey;
- (instancetype)initWithAccessKey:(NSString *)accessKey
                        secretKey:(NSString *)secretKey sessionKey:(NSString*)sessionKey;
@end

.m文件

+ (instancetype)credentialsWithAccessKey:(NSString *)accessKey
                               secretKey:(NSString *)secretKey sessionKey:(NSString*)sessionKey
{
    CustomCredentialsProvider *credentials = [[CustomCredentialsProvider alloc]initWithAccessKey:accessKey secretKey:secretKey sessionKey:sessionKey];
    return credentials;

}

- (instancetype)initWithAccessKey:(NSString *)accessKey
                        secretKey:(NSString *)secretKey sessionKey:(NSString*)sessionKey
{
    if (self = [super init]) {
        _accessKey = accessKey;
        _secretKey = secretKey;
        _sessionKey = sessionKey;
    }
    return self;
}
