我正在研究iphone应用程序库。根据我的要求,我需要使用php url将摄像机捕获的图像发送到服务器。我将捕获的图像存储在应用程序资源文档目录中。
这是我的PHP代码-
$file_path = "../Gallery/";
$file_path = $file_path . basename( $_FILES['Documents']['name']);
if(move_uploaded_file($_FILES['Documents']['tmp_name'], $file_path)) {
echo "Image is upload";
} else{
echo "Image is not Upload";
}
这是我的iPhone代码-
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
UIImage *image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
CGFloat compression = 0.5f;
UIImage *smallSizeImage = [self scaleImage:image toSize:CGSizeMake(140.0, 80.0)];
imageData = UIImageJPEGRepresentation(smallSizeImage, compression);
ivPicture.image = smallSizeImage;
self.passingNbPosition.positionImageId = [Util getNewGUID];
[imageData writeToFile:[Util getFilePathForFileName:[NSString stringWithFormat:@"%@.jpg",self.passingNbPosition.positionImageId]] atomically:YES];
// setting up the URL to post to
NSString *urlString = @"http://...........php";
// setting up the request object now
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:@"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]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"userfile\"; filename=\"%@.jpg\"\r\n", self.passingNbPosition.positionImageId] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData]];
[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(returnString);
}
在控制台中打印后使用上面的代码,我正在获取返回数据,但返回字符串即将到来“图像未上传”。我不知道我的错误在哪里。我认为这是我的iPhone代码中的问题。有人可以帮我在这里我做错了什么。
谢谢..
最佳答案
- (void) saveImageInServer
{
/*
turning the image into a NSData object
getting the image back out of the UIImageView
setting the quality to 90
*/
NSData *imageData = UIImageJPEGRepresentation(self.profilePicture.image, 90);
// setting up the URL to post to
NSString *urlString = @"http://webservices/image-upload.php";
// setting up the request object now
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init] ;
[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 = @"---------------------------147378098314876653456641449";
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 *stringData = [NSString stringWithFormat:@"Content-Disposition: form-data; name=\"userfile\"; filename=\%@.jpg\r\n",self.emailTextField.text];
[body appendData: [stringData dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[@"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData]];
[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(@"%@",returnString);
}
正如我告诉您的,这是应用程序中的代码,请检查服务器中的Gallery文件夹,如果该文件夹存在并且您指向该文件夹,则它将起作用
