推荐答案

postURL 参数的值是一个可以无异常解析的 URL，所以问题出在别的地方.你可以做什么:

The value of the postURL parameter is a URL that can be parsed without exceptions, therefore the problem is somewhere else. What you can do:

• 使用各种小程序参数进行实验
• 寻求小程序开发者的支持
• 如果你没有小程序的源代码，你可能仍然可以反编译它，看看它是如何工作的:在哪里可以找到 Java 反编译器?

以下程序仅显示 postURL 值适用于 Java:

The following program shows only that the postURL value is OK for Java:

public class A {
    public static void main(String[] args) throws MalformedURLException {
        String s = "http://xxx.ccc.local/upload/up.php?aa=0&bb=Alvar%E1%2Ffg&cc=1028&from=documentos";

        URL url = new URL(s);
        String protocol = url.getProtocol();
        System.out.println(String.format("A::main: protocol = '%s'", protocol));
    }
}
