In the previous code, the view function returned a string, and the content of the HTML file returned in the actual development was actually a string. Below is a summary of several ways in which flask can be used as a response. 1, response string.
This has been explained earlier, but it should be noted that in fact, every time a view function responds with a statu
duplicate code in each view function, Flask provides the ability to register common functions, which can be invoked before or after a request is distributed to a view function.
The request hook is implemented using an adorner, and flask supports the following 4 hook before_first_request: Registers a function that runs before the first request is processed. Before_request: Registers a function that runs bef

At the top, we need to reference the Axios library. Then there is a new methodGetrandomfrombackendThe API and retrieval results will be called asynchronously using Axios. Finally,GetrandomThe method should be used nowGetrandomfro

Will eventually be processed into response objects by flask.Cookies object:Cookies are used to store some information on the client, and when the flask application responds to user requests, the value of the cookie can be set, and the value of the cookie can be obtained when the user requests the Flask application.To put it simply, cookies are set up in the fol

Although small web applications can be easily expanded with a single script, this method cannot be well expanded. As the application becomes more complex, processing in a single large source file becomes more and more problematic.
Unlike most other web frameworks, F
Article Description: To be honest, the first time I hear the "response icon" I feel weird, just as it was not so long ago that people changed their size in order to make the icon font more suitable for different devices, but the idea made a great progress in response design and icon design. So today, we're going to be 818, what the hell is this thing?
Here to monitor memory usage as an example, write a simple demo program, the specific operation according to the 51reboot tutorials written below.
First, the establishment of a database to build tables
To create a Falcon database:
Mysql> CREATE DATABASE Falcon character set UTF8;Query OK, 1 row Affected (0.00 sec)To create the table stat used by memory monitoring, the table structure is as follows:

This article describes how to use the hasOwnProperty method in Js to retrieve ajax response objects. The technique described in this article is the use of the hasOwnProperty method in ajax requests, if you need a friend, you can refer to those who often use Baidu search. The drop-down index of the input box will not be ignored. It is so convenient. However, the unique condition makes this asynchronous technology somewhat challenging, highly Concurrent
Often use Baidu search students, will not ignore the input box Drop-down index, it is so convenient, however, the unique conditions make this asynchronous technology to face some of the test, high concurrent service-side request to urge their front-end siege master must minimize the number of times to send Ajax. It doesn't sound like this, but it doesn't. First of all, let us for Baidu for free to do an ad bar. In Baidu first enter the word "front-end
When designing a responsive page, the hardest part is the processing of table tables, which are essential elements in data table design, and play an important role in data application projects, but it's a bit of a hassle to make the tables fit into a variety of screens. This article will use an example to show you how to use the CSS3 to implement the response dat
Sometimes you need to know the execution time of the command, for example, you can use Invoke-webreques to view the response of a Web site, and then use Measure-command to calculate the time of execution.
Copy Code code as follows:
$url = ' http://www.powershell.com '
# Track Execution Time:
$timeTaken = measure-command-expression {
$site = Invoke-webrequest-uri $url
}
$milliseconds = $t
