javascript - 在请求目标中发现无效字符。有效字符在 RFC 7230 和 RFC 3986 错误中定义 GET 请求与 tomcat 9.0.7

Question

我正在使用Apache Tomcat/9.0.7。我要求外部来源如下。

var loc = "<%=request.getContextPath()%>/webpages/PS.jsp?jsonArry="+jsonArry; 
document.getElementById('PSFrame').setAttribute('src', loc);

下面我提到了我得到的错误

java.lang.IllegalArgumentException: Invalid character found in the request target. The valid characters are defined in RFC 7230 and RFC 3986
