Question

我们需要为文件创建共享链接，然后检索该链接我们可以在我们的应用程序中显示它。我们能够为特定文件创建共享链接（我们可以看到它）在Web上的Box帐户中）但我们无法检索sharedLink 通过API。虽然isShared方法返回YES，但它始终为零。

从BoxObject.h的头文件中我们发现这两种方法提供了有关项目共享状态的必要信息。

@protocol BoxObject
// ...


// Information about the shared state of the item
@property (readonly, getter = isShared) BOOL shared;
@property (readonly) NSString *sharedLink;

//...
@end

这就是我们创建共享链接的方式。

查找我们想要分享的BoxFile，让我们调用该对象 photo 先前的调用方法shareWithPassword：message：email：callbacks：，[photo isShared]返回NO。
我们致电[photo shareWithPassword:@"" message:@"" emails:[NSArray arrayWithObject:@""] callbacks:^(id<BoxOperationCallbacks> on1){...}];
在on1.100之后我们检查是否响应== BoxCallbackResponseSuccessful 然后我们调用[photo updateWithCallbacks：^（id ON2）{..}]
在on2.after我们检查是否响应== BoxCallbackResponseSuccessful
成功回复[photo isShared]会返回YES，但是[照片 sharedLink]返回nil

如果我们检查网络，我们可以看到该文件实际上是共享的，但我们无法从Box SDK中检索sharedLink。

任何人都有同样的问题吗？

根据已发布的代码和github上发现的信息here

，这对我有用

- (void) getShareableLinkForFileId:(NSString *)fileId 
{
    BoxFileBlock fileSuccess = ^(BoxFile *file) {
            NSDictionary *fileInfo = file.rawResponseJSON;
            if (![fileInfo[@"shared_link"] isEqual:[NSNull null]]) { 
            NSDictionary *linkData = fileInfo[@"shared_link"];
            //Do something with the link
        } else {
            // failure
        }
    };
    BoxAPIJSONFailureBlock failure = ^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, NSDictionary *JSONDictionary) {
         //Handle the failure 
    };

    BoxFilesRequestBuilder *builder = [[BoxFilesRequestBuilder alloc] init];
    BoxSharedObjectBuilder *sharedBuilder = [[BoxSharedObjectBuilder alloc] init];
    sharedBuilder.access = BoxAPISharedObjectAccessOpen;
    builder.sharedLink = sharedBuilder;
    [[BoxSDK sharedSDK].filesManager editFileWithID:fileId requestBuilder:builder success:fileSuccess failure:failure];
}

我能够通过刷新文件夹本身来获取共享链接。这是我提出的代码：

[boxFile shareWithPassword:@"" message:@"" emails:@[ @"" ] callbacks:^(id<BoxOperationCallbacks> on) {
    on.after(^(BoxCallbackResponse response) {
        if (response == BoxCallbackResponseSuccessful) {
            [self.rootFolder updateWithCallbacks:^(id<BoxOperationCallbacks> on) {
                on.after(^(BoxCallbackResponse response) {
                    BoxFile *updatedBoxFile = (BoxFile*)[self.rootFolder.children objectAtIndex:self.selectedIndexPath.row];
                    NSString *fileName = updatedBoxFile.name;
                    NSString *shareLink = updatedBoxFile.sharedLink;

                    NSLog(@"%@ [%@]: %@", fileName, updatedBoxFile.isShared ? @"YES" : @"NO", shareLink);
                });
            }];
        } else {
            [BoxErrorHandler presentErrorAlertViewForResponse:response];
        }
    });
}];

这是旧的v1 API。不确定它是否随着更新的v2而改变。

您可以通过使用Box V2编辑其信息来创建共享链接：

 Box2FolderBlock folderSuccess = ^(Box2Folder *folder) {
    if (![[folder sharedLink] isEqual:[NSNull null]]) {
        NSString *sharedUrl = [[folder sharedLink] objectForKey:Box2APIObjectKeyURL];
    } else {
        // failure
    }
 };

 Box2FileBlock fileSuccess = ^(Box2File *file) {
    if (![[file sharedLink] isEqual:[NSNull null]]) {
       NSString *sharedUrl = [[file sharedLink] objectForKey:Box2APIObjectKeyURL];
    } else {
       // failure
    }
 };

 Box2APIJSONFailureBlock failure = ^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, NSDictionary *JSONDictionary) {
 };

BoxSharedObjectBuilder *sharedLinkObject = [[BoxSharedObjectBuilder alloc] init];
sharedLinkObject.access = BoxAPISharedObjectAccessOpen;

BoxAPIJSONOperation *operation;

if (isFile == NO) {

    sharedLinkObject.canPreview = BoxAPISharedObjectPermissionStateEnabled;

    BoxFoldersRequestBuilder *requestBuilder = [[BoxFoldersRequestBuilder alloc] init];
    requestBuilder.sharedLink = sharedLinkObject;

    operation = [boxSDK.foldersManager editFolderWithID:fileOrFolderId requestBuilder:requestBuilder success:folderSuccess failure:failure];

} else {

    sharedLinkObject.canDownload = BoxAPISharedObjectPermissionStateEnabled;

    BoxFilesRequestBuilder *requestBuilder = [[BoxFilesRequestBuilder alloc] init];
    requestBuilder.sharedLink = sharedLinkObject;

    operation = [boxSDK.filesManager editFileWithID:fileOrFolderId requestBuilder:requestBuilder success:fileSuccess failure:failure];
}

iOS BoxSDK为sharedLink返回nil
