php做服务端接受数据问题

Jun 23, 2016 pm 02:00 PM

底层不太懂队友做的只能发送http报文 data中的数据是要读取的,我应该怎么与他进行通信啊!我尝试用curl读取可是不成功

curl_setopt($ch, CURLOPT_URL,"192.168.16.254:8080");        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);        //要求保存到字符串还是输出到屏幕上,1隐藏        curl_setopt($ch, CURLOPT_TIMEOUT, 1);//最多获取一秒的信息        curl_setopt($ch, CURLOPT_HEADER, 0);        echo $output = curl_exec($ch);        curl_close($ch);
Copy after login

求指导。

经过我查找的资料 php做的服务器接受客户端的数据可以通过$_POST,$_GET,$_REQUEST来获取。 客户端需要用对应的$_post,$_get 来提交数据,$_REQUEST似乎都可以。
至于$_POST,$_GET的区别,百度上太多了 你可以自己找找
$_POST,$_GET返回的就是你客户端传过来的参数,你可以通过处理这些参数来完成功能,至于你想返回数据给客户端,只需要echo就行了
我最近做的php服务器,不知道是什么原因,用$_POST,$_GET,$_REQUEST不能获取到数据。 所以找了$GLOBALS[$HTTP_RAW_POST_DATA]和file_get_contents("http://input")来获取数据
上面两个方式都能获取客户端post过来的请求 第一个听说似乎不能收一种数据,忘了
我使用的是第二个 $request = file_get_contents("http://input") 就得到了客户端post过来的参数了

我只是工作需要才临时做下php服务器的,没经过系统学习,所以懂得不多。刚好我刚弄好了php服务器。 希望对你有帮助。

echo $output = curl_exec($ch); 没有数据吗?

出现可能的原因
1.192.168.16.254:8080 这个页面没有输出。
2.curl连接错误,可以加curl_error查看错误。

if(curl_errno($ch)){echo 'curl error:'.curl_error($ch);}
Copy after login

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
