I am opening a webpage in the cefsharp browser and trying to send a set of JSON data to my website's .aspx page along with query string. While the query string is not an issue but sending the JSON data to the same URL is what I am trying to fix. Earlier I was using Window's native WebBrowser control's Navigate method where I was passing the URL along with query string as well as a byte array. But, I don't find any such method to post the data. Various discussion and posts regarding the same don't have a clear example. Can you provide a sample code/example to show how to achieve that? Here is the code I've been using:
ChromiumWebBrowser browser = new ChromiumWebBrowser();
browser.Address = "https://webhook.site";
browser.Width = System.Windows.SystemParameters.PrimaryScreenWidth;
browser.Height = System.Windows.SystemParameters.PrimaryScreenHeight;
browser.RequestHandler = this;
browser.IsBrowserInitializedChanged += (sender, args) =>
{
if (browser.IsBrowserInitialized)
{
browser.LoadUrlWithPostData("https://webhook.site/#/cba9d04b-01ff-40ef-b223-0917d127ecbe/6ce82e34-28df-4900-88ef-c932a446c6b0/1", Encoding.UTF8.GetBytes("test=123&data=456"));
}
};

I have ASP.NET Core MVC back-end api. One controller returns File from server. Is there a way to make request to api route by [href] attribute of <a> tag? Looks like it tries to call React route but not make a request to server.
Also I made AJAX call to that controller and got back file as a string (screenshot is attached). Why is it a string, shouldn.t it be a byte array? How to build back file from that string? (it's a .pdf file). I have an empty PDF if use JavaScript new File([], 'name', {options}).
ASP.NET Core controller returns PDF this way:
return PhysicalFile(Path.GetFullPath(relativePath), "application/pdf", reportName);
In React I receive it as a string this way:
let stringPDFBinary = await ReportService.getReport(id, reportFileName)
I just need to download file from api by any way.
So, the answer is here: PDF is blank when downloading using javascript
The same problem. Let it be one more topic, easier to find for others. The AJAX response is encoded string. In request config set 'responseType = 'arraybuffer'' somehow and receiving pdf will not be blank. Solved.
I Just copied and pasted from the code source. The problem seems to be the same that i had:
Asp net controller:
[HttpGet]
[Route("File")]
[AllowAnonymous]
public IActionResult GetFile(string key)
{
var file = (FileCacheValue)_fileCache.Cache[key.Replace(" ", "+")];
if (file == null)
return NotFound();
Response.Headers["content-disposition"] = $"inline;filename={file.Name}.pdf";
return File(file.Data, "application/pdf");
}
In this case comes from a cache system. The data is a byte array.
Front-end React:
const onClick = () =>
{
window.open(pdfByteArray, '_blank', 'fullscreen=yes');
}
Exactly what i have. I just put the data on a new window and open the pdf.
The Ajax part is straight forward, get the value from the response and set it on a variable
I have a React Native app that uses the dom-parser module to extract relevant pieces of information from a website, which is not owned by me. The information that I need is loaded dynamically in the page after it finishes loading in the browser. Is there a way to get this in a react native app using fetch()? I don't want the users to see the website open up in the app.
What I've tried:
const html = (await (await fetch(this.search_url)).text()); //get the document
var dom = parser.parseFromString(html); //parse it
var json = dom.getElementsByTagName("script")[5].innerHTML //this is the element that I need
console.log(json)
fetch(this.search_url).then((response)=>response.json()).then((json)=>{
var dom = parser.parseFromString(html);
var json = dom.getElementsByTagName("script")[5].innerHTML
console.log(json)
})
Both of these return a blank response as output. However, when I looked up the source of this.search_url in a browser, it is loading the data after a few seconds of loading the page. Is there a way to get this data in the app? Maybe some trick to make fetch() wait for a few seconds before writing the response?
I am trying to append the recorded video which is blob object into quill editor but the video which is appended in the editor is not playable.
Able to see only the blob object getting printed in the quill editor. If i try to open the contents in the browser it is working fine. Any suggestions?
enter image description here
well,according to this issue,
I think you maybe need to overwrite the video module's sanitize method to make it work,for image it can work like this:
var Image = Quill.import('formats/image')
Image.sanitize = function(url) {
return url
}
so as I guess, following things maybe useful:
var Video = Quill.import('formats/video')
Video.sanitize = function(url) {
return url
}
and you may need provide blob url to make it work
I have a page data folder with a property "Image", which is a reference to a Media file in the Composite C1 backend.
I now want to retrieve the data in my asp.net user control, but all I get when I access the "Image" Property of my PageDataFolder Type, is a string with the following format:
mediaarchive:b5354eba-3f69-4885-9eba-74576dff372d
I am not sure how to get the external image url from that. Is there an API function I can use?
Build a url like
~/media({MediaKey})
example: "~/media(mediaarchive:b5354eba-3f69-4885-9eba-74576dff372d)"
Once C1 page is rendered, it will be replaced with the following SEO friendly url:
/media/{Path to your image in media archive})
example: "/media/5611182f-6462-4b80-a051-3c3b9bb3276d/References/Screenshots/Olympiacos/1_png"
Note that you can specify image resing/cropping options via query string.
http://docs.composite.net/Getting-started/Configuration/Resizing-Images
If you, for some reason cannot rely on the C1 page rendering logic, you can build a public media url with the following code:
protected string GetMediaUrl(string mediaPath)
{
string[] parts = mediaPath.Split(new[] { ':' });
string mediaStore = parts[0];
Guid mediaId = new Guid(parts[1]);
string mediaUrl = MediaUrls.BuildUrl(new MediaUrlData { MediaStore = mediaStore, MediaId = mediaId, QueryParameters = new NameValueCollection() },
UrlKind.Public);
// Temporary fix, allows media player to receive a nice url with an extension
return mediaUrl.Replace("_jpg", ".jpg").Replace("_mov", ".mov").Replace("_m4v", ".m4v").Replace("_swf", ".swf");
}
I found a way, but it's not exactly the shortest one:
MediaUrlHelper.GetUrl(MediaUrlHelper.GetFileFromQueryString(new NameValueCollection { {"id", myItem.Image} }))
I still hope someone comes up with a better solution, I will be happy to mark that one as the answer.
I am a new bie on GWT, I wrote an application on abc.com, I have another application i.e. xyz.com, xyz.com?id=1 provides me a data in json format, I was thinking to find a way that how to get that json file in abc.com via RPC call, because I have seen tutorials in which RPC calls are used to get data from its server. any help will be appreciated.
EDIT
I am trying to implement this in this StockWatcher tutorial
I changed my code slightly change to this
private static final String JSON_URL = "http://localhost/stockPrices.php?q=";
AND
private void refreshWatchList() {
if (stocks.size() == 0) {
return;
}
String url = JSON_URL;
// Append watch list stock symbols to query URL.
Iterator iter = stocks.iterator();
while (iter.hasNext()) {
url += iter.next();
if (iter.hasNext()) {
url += "+";
}
}
url = URL.encode(url);
MyJSONUtility.makeJSONRequest(url, new JSONHandler() {
#Override
public void handleJSON(JavaScriptObject obj) {
if (obj == null) {
displayError("Couldn't retrieve JSON");
return;
}
updateTable(asArrayOfStockData(obj));
}
});
}
before when I was requesting my url via RequestBuilder it was giving me an exception Couldn't retrieve JSON but now JSON is fetched and status code is 200 as I saw that in firebug but it is not updating on table. Kindly help me regarding this.
First, you need to understand the Same Origin Policy which explains how browsers implement a security model where JavaScript code running on a web page may not interact with any resource not originating from the same web site.
While GWT's HTTP client and RPC call can only fetch data from the same site where your application was loaded, you can get data from another server if it returns json in the right format. You must be interacting with a JSON service that can invoke user defined callback functions with the JSON data as argument.
Second, see How to Fetch JSON DATA
