我试图下载与Twilio帐户关联的所有录制对象，但在TwilioVoiceClient.h或VoiceClient.h中没有看到实现此目的的任何方法。我正在使用ProgramableVoice iOS SDK（测试版5），但在线文档不显示任何objective-c或Swift。我可以，如果拍摄SID被称为像这样以播放个人记录，没有任何问题：使用可编程语音SDK检索Twilio上的所有录制文件
NSString *baseString = @"https://api.twilio.com/2010-04-01/Accounts/";
NSString *recordingSID = @"RExxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
NSURL *recordingUrl = [NSURL URLWithString:[NSString stringWithFormat:@"%@%@/Recordings/%@.mp3", baseString, kTwilAccount, recordingSID]];
avPlayer = [[AVPlayer alloc]initWithURL:recordingUrl];
我想什么做虽然是下载所有相关的记录对象帐户。对于这一点，我转身NSURLConnection的：
NSString *baseStr = [NSString stringWithFormat:@"https://api.twilio.com/2010-04-01/Accounts/%@/Recordings.json", kTwilAccount];
NSURL *url = [NSURL URLWithString:baseStr];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:1000.0];
NSString *authStr = [NSString stringWithFormat:@"%@:%@", kTwilAccount, authToken];
NSData *authData = [authStr dataUsingEncoding:NSASCIIStringEncoding];
NSString *authValue = [NSString stringWithFormat:@"Base %@", [authData base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength]];
[theRequest setValue:authValue forHTTPHeaderField:@"Authorization"];
[NSURLConnection sendAsynchronousRequest:theRequest queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse *responseCode, NSData *responseData, NSError *responseError) {
if ([responseData length] > 0 && responseError == nil){
// do work
} else if ([responseData length] == 0 && responseError == nil){
NSLog(@"data error: %@", responseError);
} else if (responseError != nil && responseError.code == NSURLErrorTimedOut){
NSLog(@"data timeout: %ld", (long)NSURLErrorTimedOut);
} else if (responseError != nil){
NSLog(@"data download error: %@", responseError);
}
}];
这导致下载错误与控制台输出：
数据下载错误：错误域= NSURLErrorDomain代码= -1012 “（空）” 的UserInfo = {NSErrorFailingURLStringKey = https://api.twilio.com/2010-04-01/Accounts/ACdee27262ef5fd27a593a697d80e7f7b0/Recordings.json，NSUnderlyingError = {0x17084aa70误差区域= kCFErrorDomainCFNetwork代码= -1012 “（空）” 的UserInfo = {_ kCFURLErrorAuthFailedResponseKey = {URL = https://api.twilio.com/2010-04-01/Accounts/ACdeedkfdjieireijrekjrkejrk4kj4/Recordings.json}}}，NSErrorFailingURLKey = https://api.twilio.com/2010-04-01/Accounts/ACdeedkfdjieireijrekjrkejrk4kj4/Recordings.json}
显然，要么不识别端点或不识别端点就像我认证的方式一样。我应该如何在objective-c中请求这些信息？
