and secure.Second, it is not easy to determine whether JSONP requests fail. Although HTML5 adds an onerror event handler to the element, it is not currently supported by any browsers. To do this, the developer had to use a timer to detect whether a response was received within the specified time.Second, jquery package JsonpFor developers who often use jquery, note that $.ajax there is a property in the jquery package dataType , and if you set this p

The HTTP protocol defines eight methods or "actions" to indicate different ways to manipulate the resources specified by the Request-uri.The details are as follows:OPTIONS: Returns the HTTP request method that the server supports for a specific resource. You can also test the functionality of your server with a request to send a ' * ' to the Web server.HEAD: Ask the server for a response that is consistent with the GET request, except that the response body will not be returned. This method allo

When doing web development, when the session expires, if it is not an AJAX request, it is easy to jump to the specified page. But there are problems with Ajax requests. When the session expires, clicking on the AJAX request will pop up some page source files. First, an interceptor was built to determine the session timeout. User Login will save user information in a session, in the session of the listener, session timeout will destroy the user informa

What is the difference between request payload and FormData in HTTP requests?Formdata and payload are two formats that the browser transmits to the interface, both of which are differentiated by content-type (understanding Content-type), if application/ x-www-form-urlencoded words, then the Formdata way, if it is Application/json or multipart/form-data, then request payloadthe way .For example, the following code that uses AJAX to submit a POST reques

For example, I have developed a microservices and want to test how well they perform under large concurrent requests.A convenient approach is to use tool JMeter to construct these requests.To create a new project:Create a new thread Group, meaning that the project will use 3 threads to send the request at the same time, each request executes once.In this thread group, create a new HTTP request that maintains the following properties. Protocol:https Server Name: Http Request Meth

Ajax is a shorthand for asynchronous JavaScript and XML, a mechanism for updating parts of a page. It gives you the power to update a part of the page after getting the data from the server, thus avoiding refreshing the entire page. In addition, the local updating of the page in this way can not only effectively create a smooth user experience, but also reduce the load on the server. The following is an analysis of a basic Ajax request: var xhr = new XMLHttpRequest (); Xhr.open (' Get '
