javabridge处理php上传文件显示权限不够,该如何处理
javabridge处理php上传文件显示权限不够
网站需要用到对用户上传文件进行格式校验的功能，有个开源的java类实现了这个功能。所以我除了apache之外，在机器上另外搭建了一个tomcat服务器，上面跑个php/javabridge。然后在apache上用php调用java类，现在的问题是，java类需要一个文件路径作为参数，我如果将普通的文件的绝对路径传递给java类，那么它能正常实现功能，如果我直接将上传文件的$_FILE['uploaded_file']['tmp_name']传递过去，那么tomcat那边就会报错， I/O error: /tmp/phpbpaDAG (权限不够) ，这是为什么呢？
理论上来说，java类只需要一个只读的权限，而且，如果传递的是一个普通的文件路径，那么即使这个文件只允许apache之外的用户读，那么java类也能正常实现功能。
在此请教各位。
------解决方案--------------------
1、你可以在 php 中检查一下文件的权限，看看是否能被tomcat读取
2、你可以先移动文件到自己的目录，然后再传给java
3、不就是格式校验吗？移植到php也不是难事，开源的嘛

Break or return from Java 8 stream forEach?
Feb 07, 2025 pm 12:09 PM
Java 8 introduces the Stream API, providing a powerful and expressive way to process data collections. However, a common question when using Stream is: How to break or return from a forEach operation? Traditional loops allow for early interruption or return, but Stream's forEach method does not directly support this method. This article will explain the reasons and explore alternative methods for implementing premature termination in Stream processing systems. Further reading: Java Stream API improvements Understand Stream forEach The forEach method is a terminal operation that performs one operation on each element in the Stream. Its design intention is

Java Program to Find the Volume of Capsule
Feb 07, 2025 am 11:37 AM
Capsules are three-dimensional geometric figures, composed of a cylinder and a hemisphere at both ends. The volume of the capsule can be calculated by adding the volume of the cylinder and the volume of the hemisphere at both ends. This tutorial will discuss how to calculate the volume of a given capsule in Java using different methods. Capsule volume formula The formula for capsule volume is as follows: Capsule volume = Cylindrical volume Volume Two hemisphere volume in, r: The radius of the hemisphere. h: The height of the cylinder (excluding the hemisphere). Example 1 enter Radius = 5 units Height = 10 units Output Volume = 1570.8 cubic units explain Calculate volume using formula: Volume = π × r2 × h (4
