  • cout<<"Please input the name of student file:\n"; cin>>fileName; //输入文件名 ofstream outstuf(fileName,ios::out); //关联文件和流 if(!outstuf) //成功打开文件检测 { cerr<<"File could not be open."<>...

    在我建立一个包含学生信息的文本文件,并向文件输出数据时,出现了堆栈问题。源码如下:

    #include "stdafx.h"
    #include <iostream>
    #include <fstream>
    #include <stdlib.h>
    
    using namespace std;
    
    int _tmain(int argc, _TCHAR* argv[])
    {
    	//学生信息
    	char name[30];
    	int number,score;
    	char fileName[30];
    	cout<<"Please input the name of student file:\n";
    	cin>>fileName;	//输入文件名
    	ofstream outstuf(fileName,ios::out);	//关联文件和流
    
    	if(!outstuf)	//成功打开文件检测
    	{
    		cerr<<"File could not be open."<<endl;
    		abort();
    	}
    
    	outstuf<<"学生成绩文件\n";
    	cout<<"Input the number,name,and score:"
    		<<"(Enter Ctrl+Z to end input)\n? ";
    	while(cin>>number>>name>>score)
    	{
    		//向文件顺序写入学生信息
    		outstuf<<number<<' '<<name<<' '<<score<<'\n';
    		cout<<"? ";
    	}
    	outstuf.close();
    	
    	return 0;
    }
    
    结果
    Please input the name of student file:
    D:\\ApplicationWorkSpace\\C++\\ReadandWriteStuScore\\student.txt
    Input the number,name,and score:(Enter Ctrl+Z to end input)
    ? 20200301 阿花 89
    ? 20200302 阿牛 92
    ? 20200309 二狗 66
    ? ^Z
    请按任意键继续. . .

    文件内容能够成功插入:

    报错如下:

    错误提示,name附近出现堆栈的问题,这种情况下一般就是出现数组越界的情况

    解决方式:

    仔细查看发现,声明的 fileName[] 数组,容量为30。我们却对其赋值为 “D:\\ApplicationWorkSpace\\C++\\ReadandWrite StuScore\\student.txt”,给与的字符串远远大于30,出现数组越界,导致了这个问题,将数组容量扩大后,问题消失。即:

    char fileName[300];

    Spring 5.0.3 RequestRejectedException: The request was rejected because the URL was not normalized

    spring security配置拦截请求报错:不是正规的URL请求被拒绝。

    解决办法:

    Spring security文档提到请求阻塞的问题。

    例如:它可能包含路径遍历序列(像/../)或者多转发斜杠(//),也可能是因为模式匹配失败。一些正规化的容器在执行Servlet映射之前输出这些异常,但是其它的不会。为了保护这里不利的问题,FilterChainProxy使用HttpFirewall 策略去检查和封装请求。非正规的请求默认自动拒绝,路径参数和和双斜杠为了匹配目的被移除。

    因此这里有两个可能的解决方法:

    1、移除双斜杠(首选的方式)

    2、在spring security通过自定义的StrictHttpFirewall允许双斜杠,使用如下代码

    步骤1,创建自定义firewall,允许斜杠URL

    注意:文章到这里还没有完,由于篇幅限制,完整内容请到hongfu951博客上查看

    apk手动去安装可以,通过代码安装则需要获取运行时权限,不然就会出现安装包解析错误的情况。或者自己到app里面的permission打开存储权限

    查看源码springStrictHttpFirewall.java中报错源码如下:
    在这里插入图片描述

    判断逻辑在isNormalized(request)函数中,如果请求路径中包含双斜杠//,则会抛出这样的错误。
    在这里插入图片描述

    查看我们的请求,请求中确实包含如下路径:
    在这里插入图片描述

    参照 https://stackoverflow.com/questions/48453980/spring-5-0-3-requestrejectedexception-the-request-was-rejected-because-the-url/49116274 解决方案,通过自定义Firewall的方式允许URL中出现斜杠slash

    @Bean
    public HttpFirewall allowUrlEncodedSlashHttpFirewall() {
        StrictHttpFirewall firewall = new StrictHttpFirewall();
        firewall.setAllowUrlEncodedSlash(true);    
        return firewall;
    }
    

    添加之后,正常访问
