Java 分析字符0处输入的数据org.json.jsonexception结尾时出错

我一整天都在查看我的代码，找不到为什么会发生这种情况（或者为什么它实际上没有从MySQL服务器返回它应该返回的结果）。 希望一双新的眼睛能找到原因

Jsonparser类

来自PHP的错误

您忘记了“；”in:

提示的可能重复：如果只有

POST

和

GET

有意义，那么如果你得到了其他东西，你就不应该继续。不要吞下异常-它真的没有帮助；它只是推迟了一个错误。可能是UTF-8错误？与BOM有关，或者是接近某个问题。@Trollo忘记说POST方法了d工作正常，只有当我执行上述GET do it error Out时，您的PHP服务器的日志会说什么？提示的可能重复：如果只有
