, the exception filter is invoked, the exception is checked, and some actions are taken, such as logging, providing a new response object to handle the exception, etc.
Tip: In MVC4, it is recommended to use the synchronous base class, which is recommended in later versions to extend the application using asynchronous interfaces.In addition, you need to pay attention to the scope of use of the filter, including: Global, add in Filterconfig; class-level filters, by adding attributes, me
1. Rest and restful API best practicesQuestion: 1. What is the relationship between the rest concept service, which is a resource, and what is now a popular micro-service?2. There is a need to explore in-depth open interfaces and how restful APIs are used in internal development to choose the restful specification.Application keywords: single-page app spa, mobile device, front-end separationSummary: " Empirical Summary: For the Open API, watercress, Sina Weibo, GitHub, easy to use, very suitable
HTML5 mobile web Application Development-SAP UI5 (6)
· In SAP UI5, use the i18n file to parse variables. For different language packs developed in the future, different i18n files are also available. Let's take a general look at how i18n is used in SAPUI5.
First, create a file named i18n. properties. Write the following content:
ShowHelloButtonText = SayHello
HelloMsg = Hello {0}
In fact, several variable or method values are defined here. To call them, first modify the controller content as fol
++);Oreq.send (FormData);This way you can add some fixed fields that you don't want the user to edit, and then send them.You can then use the following code to asynchronously upload a user-selected file:function Sendform () {var ooutput = document.getElementById ("Output");var oData = new FormData (Document.forms.namedItem ("FileInfo"));Odata.append ("CustomField", "This is some extra data");var oreq = new XMLHttpRequest ();Oreq.open ("POST", "stash.p
FormData (formelement); Formdata.append (" SerialNumber ", serialnumber++); var oreq = new XMLHttpRequest (); Oreq.send (FormData);
In this way, you can add some fixed fields that you do not want the user to edit, and then send them.
WAY3: Using the Getformdata method of the Form object to generate
var formobj = document.getElementById ("myformelement"); var formdata = Formobj.getformdata ();
Using FormData object, combined with native JS, asynchronously uploads images via Ajax. Of course, the
ADO. net dataservice exposes the EDM data model by default (e.g. entity Framework) to provide a data service based on the odata protocol, but also supports custom data models, you can select another data source to implement a dataservice. Of course, as a custom data model, the query needs to return the object implementing the iqueryable interface, and the update needs to implement the iupdatable interface.

This shows only one way to initialize the Formdata through the From form "Multipart/form-data"Method="POST"Name="FileInfo">js Code
var oData = New FormData (Document.forms.namedItem ("FileInfo"));
Odata.append ( "CustomField", "This is some extra data");
var oreq = new XMLHttpRequest ();
