如何允许文件上传与WebView在Cocoa？ [英] How to allow files uploading with WebView in Cocoa?

问题描述

WebView有一个名为

WebView have a method called

- (void)webView:(WebView *)sender runOpenPanelForFileButtonWithResultListener:(id < WebOpenPanelResultListener >)resultListener

但是几乎有0个文档和详细信息。里面我显示一个打开的文件对话框，并获得所选的文件名。

But there is almost 0 doc and details on it. Inside I display an open file dialog and get the selected file name.

像这样

- (void)webView:(WebView *)sender runOpenPanelForFileButtonWithResultListener:(id < WebOpenPanelResultListener >)resultListener
{       
    NSOpenPanel* openDlg = [NSOpenPanel openPanel];

    [openDlg setCanChooseFiles:YES];

    [openDlg setCanChooseDirectories:NO];

    // process the files.
    if ( [openDlg runModal] == NSOKButton )
    {
        NSString* fileString = [[openDlg URL]absoluteString];
        [resultListener chooseFilename:fileString]; 
    }

}

但是？

我该怎么办？在网站上，它显示我选择了一个文件，但当你点击上传网站只是返回一个错误，如果没有文件上传。我应该编写处理文件上传的代码还是什么？

What should I do ? On website, it show that I selected a file, but when you click on upload the website just return an error, like if no file is uploaded. Should I write the code that handle the file upload or what ?

我很失望...

编辑：

其实我有它的工作....通过只是改变代码从这里： Cocoa webkit：如何在webkit中获取文件上传/文件系统访问有点，因为某些部分已被弃用

In fact I got it working.... By just alter the code from here: Cocoa webkit: how to get file upload / file system access in webkit a bit, as some part was deprecated

- (void)webView:(WebView *)sender runOpenPanelForFileButtonWithResultListener:(id < WebOpenPanelResultListener >)resultListener
{       
    // Create the File Open Dialog class.
    NSOpenPanel* openDlg = [NSOpenPanel openPanel];

    // Enable the selection of files in the dialog.
    [openDlg setCanChooseFiles:YES];

    // Enable the selection of directories in the dialog.
    [openDlg setCanChooseDirectories:NO];

    if ( [openDlg runModal] == NSOKButton )
    {
        NSArray* URLs = [openDlg URLs];
        NSMutableArray *files = [[NSMutableArray alloc]init];
        for (int i = 0; i <[URLs count]; i++) {
            NSString *filename = [[URLs objectAtIndex:i]relativePath];
            [files addObject:filename];
        }

        for(int i = 0; i < [files count]; i++ )
        {
            NSString* fileName = [files objectAtIndex:i];
            [resultListener chooseFilename:fileName]; 
        }
        [files release];
    }

}

推荐答案

我按照Peter Hosey的说法，哇，我的代码现在很短，工作原理相同

I followed Peter Hosey comment and wow, my code is now short and works the same

- (void)webView:(WebView *)sender runOpenPanelForFileButtonWithResultListener:(id < WebOpenPanelResultListener >)resultListener
{       
    // Create the File Open Dialog class.
    NSOpenPanel* openDlg = [NSOpenPanel openPanel];

    // Enable the selection of files in the dialog.
    [openDlg setCanChooseFiles:YES];

    // Enable the selection of directories in the dialog.
    [openDlg setCanChooseDirectories:NO];

    if ( [openDlg runModal] == NSOKButton )
    {
        NSArray* files = [[openDlg URLs]valueForKey:@"relativePath"];
        [resultListener chooseFilenames:files];
    }

}
