将 AVAudioRecorder 发送到服务器 iOS

Question

过去几天我一直在尝试将本地保存的声音记录上传到服务器（服务器使用 php 文件处理它并将其保存到服务器）。 问题是我找不到办法。

在录制声音（AVAudioRecorder）时，它会保存在“NSTemporaryDirectory()”中：

NSURL *temporaryRecFile = [NSURL fileURLWithPath:[NSTemporaryDirectory() stringByAppendingPathComponent:[NSString stringWithFormat:@"VoiceFile"]]];

现在，我检查的所有地方都是使用ASIHTTPRequest。 但问题是ios6不支持。

还有一些其他的库，但无论我如何尝试，都没有任何效果。 如果有人可以帮助我，我会很高兴...

这是我的代码：

    NSURL *temporaryRecFile;

使用 AFNetworking 进行一些更改以使一切正常工作：

• 使用appendPartWithFileURL:name:fileName:mimeType:error: 避免将歌曲数据加载到内存中。
• 按照@glenwayguy 的建议，使用单例模式来保持对AFHTTPClient 的静态引用。否则，您可能会面临过早解除分配操作的风险。
• 您应该使用AFHTTPClient -HTTPRequestOperationWithRequest:success:failure: 来调试服务器响应。您提到您的上传进度块没有触发；可能是您的服务器返回 500、400 或 404 错误。

Answer 4

此代码的主要问题可能是在其当前尝试中（以及在使用 AFNetworking 时尝试分配 NSData* songData 的注释掉代码中）是方法 upload 中的代码行应该更改自：

    NSData *data = [NSData dataWithContentsOfFile:NSTemporaryDirectory()];

到这里：

    NSData *data = [NSData dataWithContentsOfFile:temporaryRecFile];
