拍摄照片并将其发送到iPhone中的PHP服务器

Question

我正在使用类似iPhone的应用程序。根据我的要求，我需要发送相机捕获的图像到服务器使用PHP网址。我将捕获的图像存储在应用程序资源文档目录中。

这里是我的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"; 
    } 

这里是我的iPhone的代码 -

- (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); 

} 

使用上面的代码在控制台上打印时，我得到的回报数据，但返回的字符串来了之后，“图片不上传“。我不知道我的错误在哪里。我认为这是我的iPhone代码中的一个问题。有人可以帮助我，我在这里做错了。

谢谢..

- (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"]; 

     /*

     */ 
     NSMutableData *body = [NSMutableData data]; 
     [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];

     NSLog(@"%@",returnString); 


} 

这是应用程序中的代码，因为我告诉你，检查你的库文件夹在你的服务器上，如果存在的话，你都指向它，它会工作

如果你想在多/表单数据发送图像，我们有一个第三方API，它是通过ASIHttpRequest.Go下面的链接，那么你就知道如何使用它。

我没有看到你的代码的任何错误，可能有一些建议，以解决此问题：

1. 认沽采摘和上传图像中不同的方法
2. 检查服务器上如果你真的有一个名为Gallery的文件夹在正确的路径中，否则它将不起作用（尝试自己创建一个文件夹，并写入它的绝对路径）
