postman 正则提取html里的值

if($("#password").val()) {
			var encrypt = new JSEncrypt();
			var key = 'MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCs6r5IY1ecQ2SFeAIEvwJfk47L9zit4HMJ+dpdyYybFYXmJjVMFbKDZ3Gwq4h/7wqfsmzCjBMChDsiBu9e4RH9+gTeaDfhfabyAbo2oOVuBm5s1hKcsCjEYYPX7mAX/SMarqeHqUgv46LBcOw09QBYSSb/ynh+xSHEKRXyfPi/zQIDAQAB';
			encrypt.setPublicKey(key);
			var passwd = encrypt.encrypt($("#password").val());
			$("#password").val(passwd);
		}

如上图，获取key的值，在test编辑以下语句

var pubKey = responseBody.match(new RegExp("key = '(.*?)'"))

console.log(pubKey[1])
