9 years agoBest way to get a file's URL
I am making an iOS app that displays all of the images from a selected folder. To make caching the images easier and more efficient I'm using the SDWebImage Library. SDWebImage requires a URL and I'm currently using the getTemporaryLink function to get a link for each image in the folder. Is there a better way to get a URL? I'm concerned that the links expiring will cause issues.
- That is the right way to get a direct link to a file using the API.
I'll be happy to pass along as feedback or feature requests though. What specifically would be more useful? Thanks in advance!

Hi Mike, unfortunately this question sounds more like a general C# question about class and method structure and usage, which I'm afraid I can't offer help with, as it's out of scope for Dropbox API support and outside my area of expertise. Apologies I can't be of more help in that regard! - mikemalter9 years agoHelpful | Level 5
Greg,
No issues. I eventually got it worked out.
I am having an error thrown everytime I call CreateSharedLinkWithSettingsAsync. The message says: {"Value should match pattern '\\A(?:(/(.|[\\r\\n])*|id:.*)|(rev:[0-9a-f]{9,})|(ns:[0-9]+(/.*)?))\\z'\r\nParameter name: path"} and the PathLower value is: "\\NW Region Info Table Documents\\0 Special Documents please read first file in this folder\\DropboxForSeva.docx". I parsed out my local drive and folders and trimmed everything to the right of \\Dropbox. What am I missing?
Thanks!

The error message is indicating that that's not a valid path value. The Dropbox path format doesn't necessarily match local filesystem path formats. For example, in this case, the path should be like "/NW Region Info Table Documents/0 Special Documents please read first file in this folder/DropboxForSeva.docx".
In general, you should just get the PathLower value from the Metadata objects returned by other API calls, such as listFolder. - mikemalter9 years agoHelpful | Level 5
Greg,
I'm trying to synch a desktop application UI with Dropbox and I started by getting a third party control that is a tree folder control. How sure are you that Dropbox's storage is not mirrored on my machine?
- Do you have a code sample for listFolder if all I have is a path from my computer? Do I have enough information on my end to get metadata from Dropbox for a particular item?
- Do you have a code sample for getting file metadata?
Thank you.

If you use the official Dropbox desktop client, it will sync the contents of your Dropbox account to your local filesystem. Note that your local filesystem doesn't use the same path format as the remote Dropbox API though. For example, Dropbox API paths uses '/' as a separator, and not '\'.
1. The Dropbox API isn't really meant for use based on file paths originating from your local filesystem like this. It provides the entire file listing for your from the API itself. E.g., using listFolder as shown here:
https://github.com/dropbox/dropbox-sdk-dotnet/blob/9803a40b3169acf66a2d14e29af8750ebe6e3e17/dropbox-sdk-dotnet/Examples/SimpleTest/Program.cs#L267
(If you need to list the root Dropbox folder, using the empty string "" as the path.)
You can technically convert a local filesystem path, though I don't have sample code for that. For instance though, you can find the local Dropbox folder using this:
https://help.dropbox.com/desktop-web/locate-dropbox-folderThen, you can strip off the local folder root, and convert the path as necessary. (E.g., from '\" separators to "/".)
2. The listFolder method as above will return metadata, but you can also retrieve individual file metadata using GetMetadata as shown here:
https://github.com/dropbox/dropbox-sdk-dotnet/blob/9803a40b3169acf66a2d14e29af8750ebe6e3e17/dropbox-sdk-dotnet/Dropbox.Api.Tests/DropboxApiTests.cs#L91 - Pash2378 years agoNew member | Level 2
I have exactly the same question, but I'm writing native iOS application in ObjC.
I searched, but can't find a way to get the temporary link for a file. I found mysterious `DBFILESGetTemporaryLink` and `DBFILESGetTemporaryLinkArg`, but I don't know how to use them.
I just need an external URL for a file in Dropbox — don't want to download it to a temporary location or data in memory.

Pash237 In the Dropbox API v2 Objective-C SDK, you would use the DBFILESUserAuthRoutes -getTemporaryLink: method:
That's an RPC-style method, so it would be used the same way as the createFolder example here:
https://github.com/dropbox/dropbox-sdk-obj-c#rpc-style-request
(I.e., `[[client.filesRoutes getTemporaryLink...`)

Thanks, it works!
[[client.filesRoutes getTemporaryLink:path]
setResponseBlock:^(DBFILESGetTemporaryLinkResult *result, DBFILESGetTemporaryLinkError *routeError, DBRequestError *networkError) {
if (result) {
NSLog(@"Got URL for Dropbox file: %@", result.link);
}
}]; - rahlpanchal8 years agoNew member | Level 2
Can you please share the function that you have tried as I have same requirement and if you shared it would be helpful for me.
Thanks!

rahlpanchal Pash237 shared an example of using the getTemporaryLink method. Is that not what you're looking for? If not, please feel free to open a new thread with the details of your question.
