    这是一个创建于 3124 天前的主题,其中的信息可能已经有所发展或是发生改变。
    encrypt.setPublicKey('MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCp0wHYbg/NOPO3nzMD3dndwS0MccuMeXCHgVlGOoYyFwLdS24Im2e7YyhB0wrUsyYf0/nhzCzBK8ZC9eCWqd0aHbdgOQT6CuFQBMjbyGYvlVYU2ZP7kG9Ft6YV6oc9ambuO7nPZh+bvXH0zDKfi02prknrScAKC0XhadTHT3Al0QIDAQAB');
    
    headers: {
    	'VerificationToken': 'T1g_69b6CqBB1C0kO7XBYp_H_eVCUjnCU6GB7o3lx7VHCpSgKncivkOQuKPAxR2czgCxBb1ctnA2uK-GsIYijNH_F5Y1:Xn2ZkeeD-Ythul_Y6GxHrOcuW7bLwrUQxwf23E9hNVDPVQupoTzIdyvSch-z2-f3Ay1m8yRiISslUetKVMi3ExT1t3k1'
    },
    

    以上是一段 JavaScript 中的内容,现在要提取PublicKeyVerificationToken的值,也就是

    MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCp0wHYbg/NOPO3nzMD3dndwS0MccuMeXCHgVlGOoYyFwLdS24Im2e7YyhB0wrUsyYf0/nhzCzBK8ZC9eCWqd0aHbdgOQT6CuFQBMjbyGYvlVYU2ZP7kG9Ft6YV6oc9ambuO7nPZh+bvXH0zDKfi02prknrScAKC0XhadTHT3Al0QIDAQAB

    T1g_69b6CqBB1C0kO7XBYp_H_eVCUjnCU6GB7o3lx7VHCpSgKncivkOQuKPAxR2czgCxBb1ctnA2uK-GsIYijNH_F5Y1:Xn2ZkeeD-Ythul_Y6GxHrOcuW7bLwrUQxwf23E9hNVDPVQupoTzIdyvSch-z2-f3Ay1m8yRiISslUetKVMi3ExT1t3k1

    正则表达式应该怎么写呢???

    正则真不会~~这个直接用单引号分割字符串再取就可以呀
