Question

首先我展示我的相关代码：

将UIImage转换为NSData：

 imageData = UIImagePNGRepresentation(myImage);

然后我写了NSMutableRequest：

NSString *urlString = @"http://136.206.46.10/~katie_xueke/test.php";

NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init]autorelease];
[request setURL:[NSURL URLWithString:urlString]];
[request setCachePolicy:NSURLRequestReloadIgnoringLocalCacheData];
[request setHTTPShouldHandleCookies:NO];
[request setTimeoutInterval:30.0f];

[request setHTTPMethod:@"POST"];

然后我写了NSMutableData：

NSString *boundary = [NSString stringWithString:@"---------------------------14737809831466499882746641449"];
NSMutableData *body = [NSMutableData data];

//Image
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name =\"image\";filename=\"%@\"\r\n",imageName] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:@"Content-Type:application/octet-stream\r\n\r\n"]dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Length: %@\r\n",postLength]dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData]];
[body appendData:[[NSString stringWithFormat:@"--%@--",boundary] dataUsingEncoding:NSUTF8StringEncoding]];

$$问题是：NSData似乎无法发送到服务器端，并且在控制台窗口中显示的正文部分是这样的：

Content-Disposition: form-data; name ="image";filename="2012:03:06 15:06:48"

Content-Type:application/octet-stream



Content-Length: 164692

如何将uiimage的nsdata更改为二进制数据以便发送到php？

PS：我尝试过Uint8方法

UInt8 *rawData = [imageData bytes];

但似乎iOS 5已弃用它。

在php方面：

$uploaddir = './upload/';    
echo "recive a image";    
$file = basename($_FILES['userfile']['name']);    
$uploadfile = $uploaddir . $file;    

if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) {    
    echo "/uploads/{$file}";

}

我从其他地方复制了它，我不知道如何在网页上显示我的POST图像。

有人可以帮助我吗？

非常感谢。

最后，我自己想出了解决方案。

AFHTTPClient *client= [AFHTTPClient clientWithBaseURL:[NSURL URLWithString:@"http://XXXX"]];
NSMutableURLRequest *myRequest = [client multipartFormRequestWithMethod:@"POST" path:@"upload.php" parameters:nil constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) {
    [formData appendPartWithFileData:imageData name:@"uploadedfile" fileName:dateTime mimeType:@"images/png"];
}];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:myRequest];
[operation setUploadProgressBlock:^(NSInteger bytesWritten, NSInteger totalBytesWritten, NSInteger totalBytesExpectedToWrite) {

    NSLog(@"Sent %d of %d bytes", totalBytesWritten, totalBytesExpectedToWrite);

}];
[operation setCompletionBlock:^{
    NSLog(@"response string: %@", operation.responseString); //Lets us know the result including failures
}];

NSOperationQueue *queue = [[[NSOperationQueue alloc] init] autorelease];
[queue addOperation:operation];

我使用了AFNetworking而不是ASIHttpRequest。

在php方面，我的代码：

<?php

$filename="uploaded";
$target_path = "uploads/";

$target_path = $target_path . basename( $_FILES['uploadedfile']['name']); 

if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
    echo "The file ".  basename( $_FILES['uploadedfile']['name']).
    " has been uploaded";
} else{
    echo "There was an error uploading the file, please try again!";
}
?>

谢谢那些帮助过我的人。
