I've been trying to find an answer for this for a while and I have not come across something that explains whether it is possible or not:
I have a bunch of documents in Google Docs and I'm retrieving the list of them using gdata library. I have tried a bunch of different ways to display/open just a single one when I select one from the list but I have not been able to find what kind of request to do or url to send with the request.
The files are public and the share settings are set to public but they won't show up.
Can anyone help me out figure out how to open a Google Docs document (any file format) either in an UIWebView or in the native app?
EDIT Ok, I think there was a bit of confusion as to this question. I have a list of documents from a user's feed in which I store the resourceID of the documents in my database. These documents are public and therefore should be allowed to be opened and viewed by others. Say another user comes in and wants to view documents from another person. I call the resourceID into the viewer url and it still says it needs authorization. I figured, since the document is public, a user that has not logged in (therefore no auth token) should be able to view the document still. Just like google docs works?
The DocsSampleWindowController included with the Objective-C library includes a method that shows how to open a document using its HTML link:
- (IBAction)viewSelectedDocClicked:(id)sender {
NSURL *docURL = [[[self selectedDoc] HTMLLink] URL];
if (docURL) {
[[NSWorkspace sharedWorkspace] openURL:docURL];
}
}
I have no idea about Objective-C but I can tell you in general terms..
Just send an authenticated request at the below uri:
Be sure to replace YourDocument'sResourceID with the resource ID of the document that you want to read..
https://docs.google.com/feeds/download/documents/export/Export?id=**YourDocument'sResourceID**&exportFormat=txt&format=txt
you can also play with the variable format in the above uri.. txt gives you the simple text and no styles..

I'm trying to get Excel to download a CSV file, from a link that changes by the day, with a click on a button. The thing is, it's locked behind an agreement-number, ID and password.
I, however, got two API tokens:
TheAppSecretToken
TheAgreementGrantToken
The link is:
https://secure.e-conomic.com/secure/generelt/exportdata2.asp?mode=doexport&kartotek=5&fradato=01-01-2017&tildato=01-02-2018&vcseparator=%3B&vcQualifier=%22
If people have another way, than using a VBA-code, to download this file with a click on a button, don't hold back with the suggestion.
I appreciate any help I can get, thank you. :-)
EDIT: It's not a duplicate for another question, as this uses Tokens, and or 3 login informations.
EDIT2: nvm. that the link is changing from day-to-day, I figured out that I can just put the date as far out in the future, as I like.
Edit:
I assume that the login call needs to be an POST request, but this is only a guess as I can't test it with the information you have given
Just change the loginBody with the information you need or change it to the format that the URL needs (like JSON) and you can send as many information as need
If needed you can also set more headers for any other tokens you have
URL = "YOURURL"
loginBody = "username=username&password=password&token=token"
HttpObj.Open("POST", URL)
HttpObj.SetRequestHeader("Content-Type","application/x-www-form-urlencoded")
HttpObj.Send(loginBody)

How do i download a file using VBA (Without internet explorer)
I'm fairly new to programming in general but I have delved into vb.net recently. I was looking into how to grab data from a website but don't fully comprehend how to or through what means.
My main end game is to just pull data for a lack of better word. Say for instance, a website shows text, I'd like to be able to pull that text into my program using vb.net. Is that possible?
I don't know how to use javascript, php and know only little of html/css. I'm of course willing to learn but I haven't had much luck searching for this specific information or solution. Without access to the websites database, is there another way for my app to read the website for what it would be displaying and retrieve this information? I'm mainly concerned with text, no other information is really needed. From what i've gathered, the information is tagged by something like an ID, or class? Any help would be appreciated.
Web servers essentially have 2 operations, POST, which is you sending something to the website, and GET, which is you requesting something from the website.
For the most part you can just do a GET of some sort on the website and it'll return what you request in a data format, likely JSON. You can often look for fields based on CSS selectors in the web page itself. Though, there are other ways and some HTTP libraries may return the data to you in various formats, mainly JSON and XML.
I'd suggest right click->view source on a web page to learn more about how they're structured. As for how to do a GET in javascript on some website, this code would grab the website at the URL you give it.
function httpGet(theUrl)
{
var xmlHttp = new XMLHttpRequest();
xmlHttp.open( "GET", theUrl, false ); //the get request
xmlHttp.send( null );
return xmlHttp.responseText; //the website data in XML format.
}
Using the Contact API v3 I had a working implementation for uploading a photo to an existing contact.
Since a couple of weeks this fails with 404. The implementation has not been changed when the API servers started to sent back 404s and I don't see any indication what exactly changed and would result now in the 404s.
I'm using HTTP PUT + the photo URL of the contact.
One interesting observation I made was that the contact's self-URL changes which each request (the provided details are still always the same and correct).
Did anyone notice something similar ?
Edit: Link to issue: http://code.google.com/a/google.com/p/apps-api-issues/issues/detail?id=3301&q=contact&colspec=API%20ID%20Type%20Status%20Priority%20Stars%20Opened%20Summary
tried different photo formats and sizes, different content types and even photos which had been uploaded previously (when it was still working). Nothing changed the behaviour of returning 404.
w.r.t to change contact ids: the contact ID changes between API invocations. I first thought it could be related to reopened connection( no keep-alive) that contact ids change. However what speaks against this being the cause of the issue is that first retrieving a contact and then editing a contact's address is possible without any issues.
authentication does not seem to be problem as well - otherwise editing a contact's address would not work as well.
PS: I'm using the JSON output format when retrieving the contact.
PS2: s/GET/PUT in step 3 ( I tried to change PUT to GET to see if it still returns 404... which it does).
PS3: am not using any client library but implement the protocol directly (which should not be relevant for the HTTP PUT on the photo link
After hours of investigation I found out that this is particular an issue using OAuth1. Using OAuth2 the exact same photo links which had been returned when requesting a specific contact record using OAuth1 work and return the photo data on HTTP GET. I expect HTTP PUT for photo links using OAuth2 to succeed as well.
Remains open if if there's some kind of workaround for OAuth1.
I have a product code which I need to enter into 6 different websites in order to pull different information from them about the product. Is there away to save this product code into some sort of variable and pass it into each websites input box and it return all the information from each one automatically? Really have no idea where to go/start with this so if anyone can brainstorm a few ideas to get me moving that would be great.
In order get what you are planning for:
You need a script which visits the specified web site,
then at the website, you can get the element by tag.
For instance in javascript,
var textBox = document.getElementByTag(Input);
This will give you a reference to text field to enter the text. It can be done as follows:
textBox.value = "any string";
Once you have done this, you will have to retrieve the results from the page, based on the website layout.
So if you can specify about your work in detail, you would get better response.
Assuming you're talking about using an ordinary GUI browser, the best you can do is copy it to your system clipboard, and paste it into each page on the browser.
If you're talking about a programmatic web-access like wget or curl, it depends on what language you are writing your script in.
you have to create the web request for each web site and find a way to parse the response which will be HTML
have a look at the HttpWebRequest you can find lots of example on internet that shows how you can create an HTTP POST to a website.

So, I have a bunch of HTML is being stored in a SQLite database, and they link back and forth amongst themselves. When a user clicks to follow a link, that request needs to be serviced by pulling the appropriate HTML out of the database. This could result in needing to load images, which are also being stored in the database (this is a future thing; there are no images yet, but I'd like to be able to use them). I've looked through the WebKit documentation, but can't quite figure out how to make this happen. I've mostly looked at WebFrameLoadDelegate and WebResourceLoadDelegate, but I didn't see one that would let me catch the request, grab the appropriate content, and then send that in a response.
Ideas? I'm pretty new to Objective-C and Cocoa, but I think I'm mostly getting the hang of things.
How do the pages which are stored in the database link to each other? It is probably easiest if they use some sort of customer URL scheme to start with.
The approach I would use is to implement
-webView:resource:willSendRequest:redirectResponse:fromDataSource:
in your resource load delegate. If the request is for a resource that is actually located in your database, return a new[1] NSURLRequest which uses a custom URL protocol which points to the database resource:
x-my-scheme:///table/row
[1] Unless you are already linking amongst your resources with the custom URL scheme - then you can skip this step.
Then, implement a custom NSURLProtocol for x-my-scheme which knows how to retrieve the data from the database. The PictureBrowser sample gives a simple example of how this is done.
