使用AFNetworking使用网络服务发送音频

Question

我有一个音频，需要与其他输入一起使用Web服务发送。经过一些搜索后，我了解到我无法使用XML SOAP消息发送nsdata，因此我在网上下载了AFHTTPRequest类并按照示例进行了操作，但无法正常工作。

这是我正在使用的Web服务：

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <addlocation2 xmlns="http://tempuri.org/">
      <userid>int</userid>
      <name>string</name>
      <voicemsg>base64Binary</voicemsg>
    </addlocation2>
  </soap:Body>
</soap:Envelope>

这是我用来发送数据和其他参数的代码：

   NSString *filePath = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"m4a"];

NSData *audio = [NSData dataWithContentsOfFile:filePath];

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

NSString *URLString = @"http://host.com/Websr/Service.asmx?op=addlocation2";//[WebService getAudioURL];
NSDictionary *parameters = @{@"userid": @2,
                             @"name": @"usertest",
                             };

manager.requestSerializer = [AFHTTPRequestSerializer serializer];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];

manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"text/html", @"audio/m4a", nil];
[manager POST:URLString parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {

    if (audio) {
        [formData appendPartWithFileData:audio name:@"voicemsg" fileName:[NSString stringWithFormat:@"test.m4a"] mimeType:@"audio/m4a"];
    }
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"Success %@", responseObject);
    NSLog(@"operation %@", operation.responseString);

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    UIAlertView *alert=[[UIAlertView alloc]initWithTitle:@"Failure" message:@"Sending Failure" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
    [alert show];
    NSLog(@"Failure %@, %@", error, operation.responseString);
}];

[self dismissViewControllerAnimated:NO completion:nil];

当应用程序到达包含AFURLResponseSerialization.h类中的数据的if语句时，该应用程序崩溃，并且访问过多，从而导致崩溃。

- (BOOL)validateResponse:(NSHTTPURLResponse *)response
                data:(NSData *)data
               error:(NSError *)error
{
BOOL responseIsValid = YES;
NSError *validationError = nil;

if (response && [response isKindOfClass:[NSHTTPURLResponse class]]) {
    if (self.acceptableContentTypes && ![self.acceptableContentTypes containsObject:[response MIMEType]]) {
        NSLog(@"[response URL] %@", [response URL]);
         if ([data length] > 0 && [response URL]) {
                ...}

您不需要使用AFHTTPRequest类。您的要求就是通过网络发送base64Binary数据，Web服务说。请点击以下链接，这将有所帮助。 http://iosdevelopertips.com/core-services/encode-decode-using-base64.html
