JSON解码导致语法错误

Question

我使用CURL函数进行API调用，而且我无法解码得到的json。

当我用json_last_error（）检查时，它说＆＃34;语法错误，格式错误的JSON＆＃34;。

但我不确定其中的语法错误是什么。

我尝试在互联网上使用以下功能，但问题仍未解决。

1. ヶ辆（（字符串）$结果）;
2. 修剪（$结果）;

我得到的结果如下：

{"transactionResponse":{"responseCode":"3","authCode":"","avsResultCode":"P","cvvResultCode":"","cavvResultCode":"","transId":"0","refTransID":"","transHash":"AA22864D4298A9C13B16CA5C4B00087F","testRequest":"0","accountNumber":"XXXX0015","accountType":"MasterCard","errors":[{"errorCode":"11","errorText":"A duplicate transaction has been submitted."}],"transHashSha2":""},"refId":"9898989898","messages":{"resultCode":"Error","message":[{"code":"E00027","text":"The transaction was unsuccessful."}]}}

请帮我解决这个问题。

非常感谢。
