Server response 102 Processing
Definition of HTTP Status Code 102
HTTP status code 102 (Processing) is defined within the WebDAV specification and indicates that the server has accepted the request but has not yet completed its processing. This status code is particularly useful in scenarios where the request requires prolonged processing time. By sending this status code, the server informs the client that it is actively working on the request, thus preventing premature timeouts.
Practical Examples of Using Status Code 102
Example 1: Long-term Data Processing on the Server
In this scenario, a user uploads a large dataset for analysis. Once the server receives the data, it may take considerable time to process the information. To keep the client informed, the server can send a 102 status code to indicate that processing is ongoing. The server might also provide periodic updates with further status codes or messages, ensuring the client is aware of the progress.
Example 2: Processing Requests for Creating Complex Objects
Consider the scenario where a user initiates the creation of a complex order that involves multiple related entities. Upon receiving the request, the server can immediately respond with a 102 status code, which signals that it is working on creating the order and associated objects. This allows the client to understand that the request is being processed, even if it takes longer than anticipated.
How to Fix Errors Related to Status Code 102 in Different Programming Languages
Example in Python
To correctly send a 102 status code from a Flask application, follow the example below:
from flask import Flask, Response, request
import time
app = Flask(__name__)
@app.route('/upload', methods=['POST'])
def upload():
# Simulate a long processing task
time.sleep(5) # Simulate processing time
return Response(status=102)
Example in JavaScript
Utilizing status code 102 in a Node.js application with Express can be done as follows:
const express = require('express');
const app = express();
app.post('/create-order', (req, res) => {
// Simulate long processing
setTimeout(() => {
res.status(102).send("Processing your order...");
}, 5000); // Simulate processing time
});
app.listen(3000);
Example in PHP
To send a 102 status code in PHP, you can use the following example:
<?php
header("HTTP/1.1 102 Processing");
// Simulate long processing
sleep(5); // Simulate processing delay
?>
Common Mistakes When Working with Status Code 102
- Incorrect usage of the status code, such as using it for completed requests.
- Client-side issues while waiting for a response, potentially leading to a poor user experience.
- Failure to manage timeouts, which can disrupt the communication between the client and server.
Tips for Optimizing Work with Code 102
- Reduce processing time by optimizing server-side algorithms and processes.
- Implement clear user feedback mechanisms, such as progress indicators, to enhance the user experience while waiting.
- Consider breaking down large requests into smaller chunks to allow for quicker responses and easier management.
