如何正确解决PHP缺少JSON包问题
这一问题的替代办法就是重写PHP json 的json_decode 和 json_encode方法。
这两个PHP缺少JSON包的解决方法主要就是把数组,字符串,或者对象 转换成 json格式的数据(特殊的一种结构体格式) 。首先需要的是json_encode方法, 此方法 主要将 数组,字符串,对象等转换成json格式。解决此问题的方法:
a. 简单版:
直接针对自己的问题需要(自己只需要将简单的数组进行操作),可以直接将此数组进行拼串。
b。完善的 encode方法:
解决PHP缺少JSON包的问题的简单方法就是 利用别人以完成的开源代码:
首先想到 zend framework。 拿来 zf_json 包中的 Decoder.PHP, 和 Encoder.PHP。 Decoder.PHP其实只要将其中某个protect方法的 protect去掉就行。 具体操作忘了,读者自行调试来解决。改写好Decoder 类后,调用如下:
<ol class="dp-xml"> <li class="alt"><span><span>$</span><span class="attribute">filepath</span><span> = $_SERVER['DOCUMENT_ROOT']; </span></span></li> <li> <span>include $filepath.'/inc/json/Encoder.</span>PHP<span>'; </span> </li> <li class="alt"> <span>$</span><span class="attribute">encoder</span><span> = </span><span class="attribute-value">new</span><span> Zend_Json_Encoder(false); </span> </li> <li> <span>$</span><span class="attribute">json</span><span> = $encoder -</span><span class="tag">></span><span>encode($result); </span> </li> <li class="alt"><span>header("X-JSON: $json"); </span></li> </ol>
json_decode方法同上,如果是PHP使用。
由于很多使用json的地方还是在ajax调用中, 所以一些ajax '框架' 提供了decode方法来解决PHP缺少JSON包这一问题:
比如在prototype中, 如果PHP页面包含了prototype.js, 那么就可以直接来调用 function(transport, json) { 。。操作} 在其中取json数据 就是 json.a , json.b 等了。
除了PHP缺少JSON包这一问题的出现外,可能遇到问题,编码。
zend framework返回的汉字编码估计不大对应(不是说它不是utf-8)我的页面编码(utf-8),因此会有问题出现。因此对于某些验证返回的报错信息(汉字)会有影响。在这里的替代方法就是使用传统的接口返回数字代码形式(通信网关经常采用的方法),比如返回 json.code 有 0,1,2,3等多种可能。则在js端处理时, 0表示成功,1表示非法的客户端数据,等等。 问题得到完美解决。

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,
