I found SPWeb.SiteLogoUrl and expected this property in CSOM and REST. But I didn't find it. How can I get a SiteLogoUrl using CSOM or REST?
SP.js
Microsoft.SharePoint.Client.dll
It was moved to the POST request that SharePoint creates while redirecting via appredirect.aspx. So, the only one way to get Site Logo Url is to handle appredirect POST request.
To initiate redirect you should use this code snippet:
Response.Redirect(TokenHelper.GetAppContextTokenRequestUrl(sharePointHostUrl, Server.UrlEncode(targetUrl)));
ContextToken, SiteLogo, Url, Title and so on can be found in the POST FormData.

I'm trying to display an Instagram feed on my website. I am not familiar with server side scripts. The explanations I have read go over my head.
I have managed to get an access key through Instagram but I don't know how to proceed.
I also tried the instructions from a video "How to implement an Instagram Feed in PHP without using the Instagram API"
For that, my php file works, displays the feed but I don't understand how to make it appear on my html page.
I'd be happy to make either method work.
In your HTML you should include a JavaScript 'script' element where you do something called an AJAX Request. The request will access the PHP file that produces the Instagram feed. ECHO the result from the PHP file and it will be returned into the DATA variable in the AJAX request. The request looks roughly like this:
$.ajax({
method: ‘POST or GET, most likely POST’,
url: ‘not always an actual url, this is the path to your PHP file’,
success: function(data) {
//php file returns into variable ‘data’
//display the feed within this function
}
});
The result from the PHP file should be echo’d back in JSON notation, if it isn’t, just add this to end of PHP the file:
$whatever = json_encode($your_result);
echo $whatever; //this is still the feed, just encoded in JSON
And if you need to decode it for some reason, just do
json_decode($variable_to_decode);
There are other parameters you can use in the AJAX request, like if for instance you need access to certain variables in your PHP file, that currently only exist in your HTML document.
this was solved by saving the html as php. i don't know why that is but it worked
I posted a request to payu server via form submit using angularjs now once payment is completed payu will return a response with hash.But when it hits my success page i get "HTTP Error 405.0 - Method Not Allowed".I found many solutions online but none of that solved my issue.What i understood is that static html do not allow post by default.But my staticFile in IIS is like below
Request Path : *
Module : StaticFileModule
Name : staticFile
Request Restriction >Verb > All Verbs & Access > Script & Invoke > Files and folders
My question now in how to allow POST method for html page.I am using angular and if i change my success url to other than mine it works fine.I think there is some changes to be made to the web config but i tried my best but failed.Any help would be much appreciated.Also lets assume that the page successfully redirects to my success page how to capture the response that payu sends me online.
Thanks in advance if more input is needed from my side kindly ask in reply.
It's not that HTML does not allow POST by default, it's that HTML does not handle POST, period. (Not even if the HTML file contains JavaScript.) POST sends data to a script that runs on your server, and the script has to be smart enough to know what to do with the data. HTML isn't that smart. The only thing your server can do with HTML is to send the HTML back to whatever is requesting it. You need a server-side script that knows how to parse payu's response, do something appropriate with the hash, and then generate some HTML to display in the user's browser.
How do you update a SharePoint 2013 wiki page using the REST API?
Three permutations:
Reading an existing page (content only)
Updating an existing page
Creating a new page
For reading an existing page, of course I can just to a "GET" of the correct URL, but this also brings down all the various decorations around the actual data on the wiki page-- rather than fish that out myself, it would be better if there was a way to just get the content if that is possible.
Are there special endpoints is the REST API that allow for any of these three operations on wiki pages?
As stated in GMasucci's post, there does not appear to be a clean or obvious way of instantiating pages through the REST API.
You can call the AddWikiPage method from the SOAP service at http://[site]/_vti_bin/Lists.asmx. This is an out of the box service that will be accessible unless it has been specifically locked down for whatever reason.
To read the content of a wiki page through the REST API, you can use the following endpoint:
https://[siteurl]/_vti_bin/client.svc/Web/GetFileByServerRelativeUrl('/page/to/wikipage.aspx')/ListItemAllFields
The content is contained within the WikiContent field. You may want to add a select to that URL and return it as JSON to reduce the amount of data getting passed over if that is a concern.
As for updating the content of an existing wiki page, it is not something I have tried but I would imagine it's just like populating another field through the REST API. This is how I would expect to do it:
Do a HTTP POST to the same endpoint as above
Use the following HTTP headers:
Cookie = "yourauthcookie"
Content-Type = "application/json;odata=verbose"
X-RequestDigest = "yourformdigest"
X-HTTP-Method, "MERGE"
If-Match = "etag value from entry node, returned from a GET to the above endpoint"
Post the following JSON body
{
"__metadata": { "type": "SP.Data.SitePagesItem" },
"WikiField" : "HTML entity coded wiki content goes here"
}
The interim answer I have found is to not utilise REST, as it appears to not be
fully documented
fully featured
supported across Sharepoint 2013 and On-line in the same way
So my current recommendation would be to utilise the SOAP services to achieve the same, as these are more documented and easily accessible.
So let's say I have a full url into a sharepoint website.
In the past when I wanted to get the weburl and doc url, I used the "url to web url" method of the Front Page Server Extensions. (http://msdn.microsoft.com/en-us/library/ms460544.aspx).
So for example if you had a site at
http://webapp/site1/chidsite/a.doc
I want a method in CSOM that will return /site1/childsite as the weburl.
I see the Web.WebUrlFromPageUrlDirect() method in CSOM but I'm not sure I'm getting what I need back from it. In the Uri class I get back, would I use teh "AbsolutePath" property for the weburl?
What is the correct way to do this?
I also would like to get the docURL that is usually retrieved by a call to url to web url via frontpage extensions.
The fileurl will be the file location relative to the web site. So if the document is stored in the document library called "Documents", you will get a value of /Documents/file.ext.
Well, I've reverted to using the FrontPage extensions when doing URLToWebURL since I just wasn't sure what I was getting using CSOM methods. Though check the link below for answers I received elsewhere.
Information Pertaining to this issue
I am trying to create an html object dynamically with the necessary header information depending on the query string in the link I provide to Facebook. I am hoping that Facebook open graph will call this html link as I provided. However it seems that query string info are not getting passed to my server. Do anyone know how to make this work or what is the more appropriate way to do this. BTW, I am writing my code in Node.js.
To get more info about Facebook open graph api, look here, https://developers.facebook.com/docs/beta/opengraph/actions/.
For example, the link I am trying to pass to Facebook is, "http://xxx-url.com/getFacebookObject?objectId=&description=first dynamic post", so I sent a request with the link as, "https://graph.facebook.com/me/app-name:action-name?object=http://xxx-url.com/getFacebookObject?objectId=&description=first dynamic post". However, when I check the log on the server, I don't see anything in the query string.
Instead of using the query string, you can embed the data in the URL:
http://some-domain.com/getFacebookObject/id/description
Then, depending on what node.js packages you're using, extract the data from the request:
// expess.js style
app.get("/getFacebookObject/:id/:description", function(req, res) {
var id = req.params.id,
desc = req.params.description;
// your code...
});
(See http://expressjs.com/guide.html.)
Sorry, Facebook will strip off all query string information from the URL when they launch your site in the iframe. If it was a page tab app, then you could add it to the app_data query string parameters which in turn gets passed to your iframe's page tab app via the app_data part of the signed_request parameter.
