返回 2017-06-28 20:32:38.981709+0800 sihou[1280:52887] 结果：{"err_msg":"json param speech error.","err_no":3300,"sn":"988868749471498653158"} 转换base64代码如下： NSData *audioData = [NSData dataWithContentsOfFile:_filePath]; NSString *base64Encoded = [audioData base64EncodedStringWithOptions:0]; NSDictionary *dic = [NSDictionary dictionaryWithObjectsAndKeys: @"wav",@"format", [NSNumber numberWithFloat: 8000],@"rate", [NSNumber numberWithFloat: 1],@"channel", @"9791201",@"cuid", token,@"token", base64Encoded,@"speech", [NSNumber numberWithInt: base64Encoded.length],@"len", nil]; 请问 speech 参数错误是什么问题？
