PHP中模拟处理HTTP PUT请求的例子
这篇文章主要介绍了PHP中模拟处理HTTP PUT请求的例子,PUT请求会把消息本体中的消息发送到一个URL,跟POST类似,需要的朋友可以参考下
关于HTTP PUT详细介绍请参阅此文:。
PHP里有$_GET,$_POST,但是没有$_PUT,所以如果需要使用它的话,则你不得不自己模拟一下:
复制代码 代码如下:
$_PUT = array();
if ('PUT' == $_SERVER['REQUEST_METHOD']) {
parse_str(file_get_contents('php://input'), $_PUT);
}
通过php://input得到的数据是raw data,所以需要用parse_str解析一下。
不过需要说明的是,当表单是enctype="multipart/form-data"类型的时候(就是上传文件那种类型),这种方法是无效的(此时 php://input为空),一旦PHP发现请求的Content-Type是multipart/form-data,就会无条件的代你处理表单数据,然后保存到$_FILES里,此时无法得到raw data,只能用一些偏门方法
以apache为例,修改httpd.conf(为了使用RequestHeader语法,请先激活header模块):
复制代码 代码如下:
RequestHeader set Content-Type foobar
通过重置Content-Type请求头为foobar(只要不是multipart/form-data即可),此时php://input就有数据了,不过原本应有的$_FILES数据却不存在了,所以基本上只有演示上的意义,如果想得到raw data,只能自己根据数据生成,在PEAR里有类似的实现:HTTP_Request2_MultipartBody。
浏览器一般只允许使用GET/POST方法,虽然可以通过JS来发送PUT方法,但是还得编写代码,相对而言,使用命令行下的CURL命令则显得方便很多,在开发测试时很有用,,所以学习一下还是必要的:
复制代码 代码如下:
curl -X PUT -d "id=1" -d "title=a"
这样就会通过PUT方法发送id, title数据,测试时demo.php的代码就类似上面的php://input。

HTTP status code 520 means that the server encountered an unknown error while processing the request and cannot provide more specific information. Used to indicate that an unknown error occurred when the server was processing the request, which may be caused by server configuration problems, network problems, or other unknown reasons. This is usually caused by server configuration issues, network issues, server overload, or coding errors. If you encounter a status code 520 error, it is best to contact the website administrator or technical support team for more information and assistance.

How to use NginxProxyManager to implement automatic jump from HTTP to HTTPS. With the development of the Internet, more and more websites are beginning to use the HTTPS protocol to encrypt data transmission to improve data security and user privacy protection. Since the HTTPS protocol requires the support of an SSL certificate, certain technical support is required when deploying the HTTPS protocol. Nginx is a powerful and commonly used HTTP server and reverse proxy server, and NginxProxy

Understand the meaning of HTTP 301 status code: common application scenarios of web page redirection. With the rapid development of the Internet, people's requirements for web page interaction are becoming higher and higher. In the field of web design, web page redirection is a common and important technology, implemented through the HTTP 301 status code. This article will explore the meaning of HTTP 301 status code and common application scenarios in web page redirection. HTTP301 status code refers to permanent redirect (PermanentRedirect). When the server receives the client's

HTTP status code 403 means that the server rejected the client's request. The solution to http status code 403 is: 1. Check the authentication credentials. If the server requires authentication, ensure that the correct credentials are provided; 2. Check the IP address restrictions. If the server has restricted the IP address, ensure that the client's IP address is restricted. Whitelisted or not blacklisted; 3. Check the file permission settings. If the 403 status code is related to the permission settings of the file or directory, ensure that the client has sufficient permissions to access these files or directories, etc.

Solution: 1. Check the Content-Type in the request header; 2. Check the data format in the request body; 3. Use the appropriate encoding format; 4. Use the appropriate request method; 5. Check the server-side support.

Quick Application: Practical Development Case Analysis of PHP Asynchronous HTTP Download of Multiple Files With the development of the Internet, the file download function has become one of the basic needs of many websites and applications. For scenarios where multiple files need to be downloaded at the same time, the traditional synchronous download method is often inefficient and time-consuming. For this reason, using PHP to download multiple files asynchronously over HTTP has become an increasingly common solution. This article will analyze in detail how to use PHP asynchronous HTTP through an actual development case.

How to use PHP to handle inline editing functions in forms Introduction: Forms are one of the commonly used elements in web development and are used to collect data entered by users.
