How to solve the 302 status code problem in axios
This time I will show you how axios solves the 302 status code problem. What are the precautions for axios to solve the 302 status code problem? The following is a practical case. Let’s take a look. .
For example, if the browser opens a single page (SPA) application, and the token (or session) expires after a while, after an Ajax request is initiated on the page, the backend returns a 302 status code and jumps to login page. I am using Vue axios and found that axios cannot intercept the 302 request. The following is the processing process.
Thinking
google axios 302 handle See two discussions on axios github
• https: //github.com/axios/axios/issues/932
• https://github.com/axios/axios/issues/980
The conclusion is: browse Ajax request sent by the server, the server returns a 302 status code, and the browser will jump on its own. We cannot directly obtain and customize the processing process through the js library (jquery, axios). We can only wait until the url is obtained after the browser redirects. Corresponding information.
axios sends ajax -->
server returns 302 and location -->
The browser requests a new url -->
The server returns 200 -- >axios Get results
So how to solve it? The server needs to cooperate to solve the problem.
Brower (ajax and not auth) -->
The server determines that it is an ajax request and is not logged in, returning a 401 status code-->
Browser axios intercepts 401 and jumps to /login through js
Solution
On the browser side, axios adds an interceptor
axios.interceptors.response.use((response) => {
return response;
}, function (error) {
if (401 === error.response.status) {
window.location = '/login';
} else {
return Promise.reject(error);
}
});
axios.defaults.headers.common['X-Requested-With'] = 'XMLHttpRequest';Back-end code, using the flask framework, just look at the process, verify whether the request is ajax and not logged in, and then return the 401 status code
from flask import Blueprint, request, jsonify, make_response, abort
from flask_login.utils import current_user, current_app
apibp = Blueprint('api', 'api_bp')
# 主要逻辑
def bp_login_required():
if not current_user.is_authenticated:
if request.is_xhr:
abort(401)
else:
return current_app.login_manager.unauthorized()
apibp.before_request(bp_login_required)
@apibp.route("/report/domains/<month>/", methods=["GET"])
def monthly_domains(month):
return jsonify({})

The clustering effect evaluation problem in the clustering algorithm requires specific code examples. Clustering is an unsupervised learning method that groups similar samples into one category by clustering data. In clustering algorithms, how to evaluate the effect of clustering is an important issue. This article will introduce several commonly used clustering effect evaluation indicators and give corresponding code examples. 1. Clustering effect evaluation index Silhouette Coefficient Silhouette coefficient evaluates the clustering effect by calculating the closeness of the sample and the degree of separation from other clusters.

In-depth understanding of the five states of Java threads and their conversion rules 1. Introduction to the five states of threads In Java, the life cycle of a thread can be divided into five different states, including new state (NEW), ready state (RUNNABLE), Running status (RUNNING), blocking status (BLOCKED) and termination status (TERMINATED). New state (NEW): When the thread object is created, it is in the new state. At this point, the thread object has allocated enough resources to perform the task

Label acquisition problem in weakly supervised learning
Oct 08, 2023 am 09:18 AM
The label acquisition problem in weakly supervised learning requires specific code examples. Introduction: Weakly supervised learning is a machine learning method that uses weak labels for training. Different from traditional supervised learning, weakly supervised learning only needs to use fewer labels to train the model, rather than each sample needs to have an accurate label. However, in weakly supervised learning, how to accurately obtain useful information from weak labels is a key issue. This article will introduce the label acquisition problem in weakly supervised learning and give specific code examples. Introduction to the label acquisition problem in weakly supervised learning:
