Good morning,

I have a code posting some data to a webserver. The server then delivers a PDF to the client (my app). But I don’t know how to open this.

The response body holds the PDF data. But how can I show it? Do I have to save the data first and then open it? If that is the case how can I do it? Or is there another way?

Here is my current code:

// Post some data and retrieve PDF
HttpRequest.post(url, defect)
    .auth(AppSettings.remoteUser, AppSettings.remotePassword)
    .set('Content-Type', 'application/x-www-form-urlencoded')
    .then(function(res) {
        let responseBody = res.body

        console.log("PDF creation OK")

        // Open the provided PDF...

})
.catch(function(err) {
    console.error(err.message)
    console.error(err.response)
})

Thank you
Martin

Hi Martin,

you could try to store the file using https://felgo.com/doc/felgo-fileutils/#writeFile-method and then open it using https://felgo.com/doc/felgo-fileutils/#openFile-method

Let me know if that works for you and maybe you can provide the example code as well.

If you are looking for an in-app PDF viewer, please reach out to us on support@felgo.com and we can discuss the available options.

Best,
Alex

Hi Alex,

I tried your solution. Problem seems to be that the response body contains binary data. When I write the data to file and try to open it, the PDF is corrupt.

Can I read the response body to binary data?

HttpRequest.get("https://www.it-syn.de/wp-content/uploads/2013/03/20150203-Firmenprospekt-it-synergy-GmbH-reduziert.pdf")
.then(function(res) {
    console.log(res.status);
    console.log(JSON.stringify(res.header, null, 4));
    console.log(JSON.stringify(res.body));

    var filePath = fileUtils.storageLocation(FileUtils.AppDataLocation) + "_packages/" + "test.pdf";
    var success = fileUtils.writeFile(filePath, res.body)
    if(fileUtils.existsFile(filePath)) {
        console.log("Open file: " + filePath)
        fileUtils.openFile(filePath)
    }
    else {
        console.log("File doesn't exist: " + filePath)
    }
})
.catch(function(err) {
    console.error("Download canceled.")
    console.error(err.message)
})

Regards,
Martin

Hi Martin,

I just applied an improvement to the HttpRequest, to correctly handle PDF binary data. With this patch, your code should work exactly as written now. This will be available with the next update, planned to be released in November still. Is that sufficient for you?

You could also make use of the DownloadableResources item instead in the meantime, to download a PDF, example is here: https://felgo.com/doc/apps-howto-access-and-store-files/

Best,
Alex

Hi Alex,

good to hear. I already use DownloadableResource as workaround. But I will need the post feature soon.

So I’m looking forward to see new release.

Thank you
Martin
