api-php中url接收的json数据,json_decode为空
phpapijson手机服务器与客户端通信
#php后台json数据decode为结果空#
我使用手机传输数据到php后台,json_decode的结果为空。
手机传输的方式为POST/GET,编码格式为UTF-8。
json数据为(包括代码中的单引号,我用字符串传输,json数据中必须为双引号):
<code> '{"agent":"30","job":"1133","students":[{"working_hours_unit":"null","working_hours":"6","student_id":"191","commission_unit":"null","wage":"58","commission":"348","wage_unit":"null"}]}'</code>
php代码获取到了以上json数据,并且能够使用echo输出。php代码:
<code> $str=$_GET('my_str'); echo $str;</code>
输出测试结果然后我接着decode接收到的json数据,代码:
<code> $form = json_decode($Noel,true); var_dump($form);</code>
但很意外输出为**null** ,然后我用_echo json_last_error();_输出json转换错误,结果为4===json语法错误。
附上完整代码和截图:
<code> $str=$_GET('my_str'); echo $str;$form = json_decode($str,true); var_dump($form); echo json_last_error();</code>
但是,当我把接收到的json单独接到PHP代码中,然后decode却能够正确解析。(我内心是崩溃的 〒_〒)
代码:`
<code> $orm='{"agent":"30","job":"1133","students":[{"working_hours_unit":"null","working_hours":"6","student_id":"191","commission_unit":"null","wage":"58","commission":"348","wage_unit":"null"}]}'; $arr=json_decode($form,true); var_dump($arr);</code>

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,

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.
