SMS APIのIOSシグネチャが無効です。エラーコード：40102メッセージ：無効な署名です。

Question

メッセージにSinchを使用していますが、ios apiの詳細ドキュメントはありません。ハッシュおよびメッセージダイジェスト認証コード40102、 "メッセージ"： "無効な署名。"、 "参照"：しかし、私は

"のerrorCode" を取得しています

ボディは、JSONまたはBase64のでフォーマットする必要があります。このコードセクションは私のために働いた：

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:hostname] 
                 cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData 
                timeoutInterval:TIMEOUT]; 
[request setHTTPMethod:@"POST"]; 
[request addValue:@"application/json; charset=UTF-8" forHTTPHeaderField:@"content-type"]; 
[request addValue:dateString forHTTPHeaderField:@"x-timestamp"]; 

NSString *authStr = [NSString stringWithFormat:@"application\\%@:%@",appKey,appSecret]; 
NSData *authData = [authStr dataUsingEncoding:NSUTF8StringEncoding]; 
NSString *authValue = [NSString stringWithFormat: @"Basic %@",[authData base64EncodedStringWithOptions:0]]; 
[request addValue:authValue forHTTPHeaderField:@"authorization"]; 

NSDictionary *messageSetup = @{ 
            @"message" : @"This is where your message goes", 
            @"from": @"YOUR NUMBER i.e. 555-555-5555" 
           }; 

NSData *dataFormatted = [NSJSONSerialization dataWithJSONObject:messageSetup options:0 error:nil]; 
[request setHTTPBody:dataFormatted]; 
NSURLSession *session = [NSURLSession sharedSession]; 
NSURLSessionDataTask *dataTask = [session dataTaskWithRequest:request 
              completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) 
            { 
             NSString *myString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; 
             NSLog(@"String Return: %@",myString); 
            }]; 
[dataTask resume];
