In web development, we often encounter situations where we need to jump to the website. For PHP developers, 307 jump is a common jump method. However, when using 307 jumps, jump errors are often encountered. This article will introduce in detail how to configure PHP to implement 307 jumps and solve common jump problems.
1. Introduction to 307 jump
307 jump is an HTTP protocol status code, indicating a temporary redirection. Different from 301 and 302 jumps, 307 jumps will not change the HTTP request method and request body, that is, the POST request will maintain the POST request method. This means that using 307 jump can solve the problem of GET and POST request processing.
2. Configure PHP to implement 307 jump
To use 307 jump, you need to add the following content to the PHP code:
header('HTTP/1.1 307 Temporary Redirect'); header('Location: http://www.example.com/'); exit();
The above code indicates that using 307 temporary Redirect status code and set the redirect address to http://www.example.com/. Among them, the exit() function means to end the execution of the script.
3. Common 307 jump problems
When using 307 jump, sometimes you will find a jump Doesn't work, even returns an error code. This is usually caused by the server configuration disabling this jump method. RewriteEngine can be turned off in the configuration file of the web server, or by adding the following rules:
if ($request_method = POST ) { return 403; }
The above code indicates that if the request method of the HTTP request is POST, a 403 error code will be returned directly. Doing this will prevent POST requests from using 307 jumps.
When using 307 jump, if the POST data is lost after the POST request jumps, it is usually due to the source PHP file and the target file are not in the same domain, or the target file uses another request method. It can be solved by adding the following code to the target file:
if ($_SERVER['REQUEST_METHOD'] == 'POST') { foreach ($_POST as $key => $value) { $_SESSION[$key] = $value; } header("Location: http://www.example.com/"); exit(); }
The above code stores the POST data into the SESSION and passes the data to the target file after the 307 jump.
