Javascript解析带有转义字符的JSON

Question

因此，我有一个从Android Pay API调用返回的JSON对象，我需要将数据提取出来并进行处理。问题是它包含必须保留的反斜杠。我已经看了很多关于这方面的线索，但似乎都不起作用。如何从下面的数据中解析出键/值对并保留数据中的反斜杠？

{"ephemeralPublicKey":"BE1Ai3\/HjtEon0JAz+9jK8GmF9vzmXpDACcpjsXDD5EkP7HmhdXrNjVMdi58itYNGH6HoZvlOY65qvHWRwS0pu8=","encryptedMessage":"BIrMosJ9dQSeCL0ImJPhml3++grM6AvW9qLkTkp6I\/gt1q+JsFB9rm9Ndzdjd7UuN\/RJm6osMHd1UDIi84VlQljJKMQnRQKrQrqx15jlNOBlGrALOTY3TQIYyWOvMB8I\/Kr6yFduvy+b2IVR+3GPDjI4J3PKHd+xPLh4WvXhmBckda54T3vVW\/2Toxi02IC1w\/n5AkTlKfem6XTvw9sC","tag":"GEyeDyeNrXn3T2GYHFOL4WeQLBRBVt7PCKmr9OfJa3M="}

Answer 1

我想通了。

var data = {"ephemeralPublicKey":"BE1Ai3\/HjtEon0JAz+9jK8GmF9vzmXpDACcpjsXDD5EkP7HmhdXrNjVMdi58itYNGH6HoZvlOY65qvHWRwS0pu8=","encryptedMessage":"BIrMosJ9dQSeCL0ImJPhml3++grM6AvW9qLkTkp6I\/gt1q+JsFB9rm9Ndzdjd7UuN\/RJm6osMHd1UDIi84VlQljJKMQnRQKrQrqx15jlNOBlGrALOTY3TQIYyWOvMB8I\/Kr6yFduvy+b2IVR+3GPDjI4J3PKHd+xPLh4WvXhmBckda54T3vVW\/2Toxi02IC1w\/n5AkTlKfem6XTvw9sC","tag":"GEyeDyeNrXn3T2GYHFOL4WeQLBRBVt7PCKmr9OfJa3M="};

var obj = JSON.parse(data.replace(/\\/g, '\\\\'));
console.log("Value: " + obj.ephemeralPublicKey);

Answer 2

我看到代码在工作，你的问题的重点是什么？

您应该转义反斜杠字符，如下所示。

var str = '{"ephemeralPublicKey":"BE1Ai3\\/HjtEon0JA"}';//...string response from api 
var obj = JSON.parse(str.replace('\\/','\\\\/'));
obj.ephemeralPublicKey
