我尝试了十几件事。但我没有收到结果。我想将音频文件 wav/mp3 转换为字节数组或以其他方式发送到 php 服务器。以下是我尝试过的一些已经在 SO 中列出的东西。请帮忙。

 NSURL *urlPath = [NSURL fileURLWithPath: [[NSBundle mainBundle] pathForResource:@"r2d2" ofType:@"mp3"]];
NSString *wavbundlepath = [urlPath absoluteString];
NSData *data = [NSData dataWithContentsOfURL:[NSURL URLWithString:wavbundlepath]];


NSUInteger len = data.length;
int8_t *bytes = (int8_t *)[data bytes];
NSMutableString *result = [NSMutableString stringWithCapacity:len];
[result appendString:@"["];
for (NSUInteger i = 0; i < len; i++) {
    if (i) {
        [result appendString:@","];
    }
    [result appendFormat:@"%d", bytes[i]];
}
[result appendString:@"]"];

NSString *urlString = @"http://apps2.mobiiworld.com/staging/krafttesting/";

// setting up the request object now
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:@"POST"];
NSData* dataSend = [result dataUsingEncoding:NSUTF8StringEncoding];
[request setHTTPBody:dataSend];

NSURLResponse *response;
NSError *err;
NSData *responseData2 = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];
NSLog(@"responseData: %@", responseData2);

下一个

NSURL *urlPath = [NSURL fileURLWithPath: [[NSBundle mainBundle] pathForResource:@"r2d2" ofType:@"mp3"]];
NSString *wavbundlepath = [urlPath absoluteString];
NSData *data = [NSData dataWithContentsOfURL:[NSURL URLWithString:wavbundlepath]];NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:@"POST"];

/*
 add some header info now
 we always need a boundary when we post a file
 also we need to set the content type

 You might want to generate a random boundary.. this is just the same
 as my output from wireshark on a valid html post
 */
NSString *boundary = [NSString stringWithString:@"---------------------------14737809831466499882746641449"];
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];
[request addValue:contentType forHTTPHeaderField: @"Content-Type"];

/*
 now lets create the body of the post
 */

NSMutableData *body = [NSMutableData data];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
NSString *filename = @"file";
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"userfile\";filename=\"%@\"\r\n", filename] dataUsingEncoding:NSUTF8StringEncoding]];
//  NSLog([NSString stringWithFormat:@"Content-Disposition: form-data; name=\"userfile\";filename=\"%@\"\r\n", filename]);
//[body appendData:[[NSString stringWithString:@"test"] dataUsingEncoding:NSUTF8StringEncoding]];
//[body appendData:[[NSString stringWithString:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:data]];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
// setting the body of the post to the reqeust
[request setHTTPBody:body];

// now lets make the connection to the web
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(@"Return :    %@", returnString);

php 开发人员说他没有收到任何数据。他回应了他收到的任何内容，但我发现一个空字符串作为回应。谁能建议该怎么做？

这就是我的做法

NSData *audioData = Here comes your NSData;
NSString *urlString = @"The url of php file";

NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:@"POST"];

NSString *boundary = @"---------------------------14737809831466499882746641449";
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", boundary];
[request addValue:contentType forHTTPHeaderField:@"Content-Type"];

NSMutableData *body = [NSMutableData data];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"userfile\"; filename=\".caf\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:audioData]];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:body];

NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSLog(@"Length : %d", returnData.length);
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(@"Return String %@", returnString);

通过 ASIHTTPRequest 还有另一种方法

NSURL *url = [NSURL URLWithString:@"the url comes here"];
ASIFormDataRequest *formRequest = [[[ASIFormDataRequest alloc] initWithURL:url] autorelease];

NSData *imageData = UIImageJPEGRepresentation([self scaleAndRotateImage:self.m_ImageViewProfile.image], 90);

NSLog(@"Size : %d", imageData.length);

[formRequest setTimeOutSeconds:600];
[formRequest setPostValue:@"If there is any"] forKey:@"the key"];
[formRequest setData:imageData withFileName:@"myphoto.jpg" andContentType:@"image/jpeg" forKey:@"filename"];

//[formRequest setUploadProgressDelegate:progressView];

[formRequest setCompletionBlock:^{
    NSString *responseString = [formRequest responseString];
    NSLog(@"Response: %@", responseString);
}];
[formRequest setFailedBlock:^{
    NSError *error = [formRequest error];
    NSLog(@"Error: %@", error.localizedDescription);
}];

[formRequest startSynchronous];

看看是不是你想要的
