接收到的json解析不了,必须用php解析
function sendPost($url,$postData){ $postdata = http_build_query($postData); $options = array( 'http' => array( 'method' => 'POST', 'header' => 'Content-type:application/x-www-form-urlencoded', 'content' => $postdata, 'timeout' => 15 * 60 // 超时时间(单位:s)) ); $context = stream_context_create($options); $result = file_get_contents($url, false, $context); return $result; }$url = "http://chepiao.sinaapp.com/api.php?act=remain";$data = array( "date"=>"20131220", "startStation"=>"北京", "arriveStation"=>"天津");$result = sendPost($url, $data); $obj = json_decode($result);$result就是返回来的数据,就是解析不了,用json_decode($result);解析成的是NULL
回复讨论(解决方案)
来人帮解析一下
打印下$result看下结果
真够可以的
gbk环境看到
{"title":"北京 - 天津 ??0娆¤溅锛?","errMsg":"????ㄥ?锛??绋????璇??"}
utf-8环境看到
{"title":"???? - ??
连csdn都不能接受这种字符集的错乱
utf-8环境看到
真奇葩
echo json_last_error();
结果是4,说明格式不正确
于是把返回的东西扔http://jsonlint.com/检测,报错,发现是换行的问题
print_r(json_decode(str_replace("\n"," ",$result)));
结果就好了。
多谢各位 json_last_error没学会用,结贴了

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.

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.
