问题 As per the API we can upload images as a binary file. https://api.imgur.com/endpoints/image#image-upload I tried the following to read the file into a byte array. // Example 1 byte[] fileBytes = new byte[(int) new File("/home/sample.png").length()]; fileBytes = FileUtils.readFileToByteArray( this.imageRequest.getFile() ); String sImageBinaryData = new String( fileBytes ); How exactly should i extract binary data of an image? PS: I am not interested to know how to upload image using (base64 &

问题 I needed to read a byte from the file, xor it with 0x71 and write it back to another file. However, when i use the following, it just reads the byte as a string, so xoring creates problems. f = open('a.out', 'r') f.read(1) So I ended up doing the same in C. #include <stdio.h> int main() { char buffer[1] = {0}; FILE *fp = fopen("blah", "rb"); FILE *gp = fopen("a.out", "wb"); if(fp==NULL) printf("ERROR OPENING FILE\n"); int rc; while((rc = fgetc(fp))!=EOF) { printf("%x", rc ^ 0x71); fputc(rc ^

问题 I would like to compile a python3 package into a distributable binary form (without sourcecode) from within the x64 Native Tools Command Prompt for VS 2019 using python 3.6 (64bit). However, i have problems specifying the correct paths to the files the package should contain. The produced folder structure in the site-packages directory is all wrong and not what i expect from my source folder structure and my setup.py . It seems for me that the modules from the top level package are treated

问题 I'm trying to write a Python program that takes multiple binary files from LabView, selected and opened from a tkinter dialog box, and converts them to readable text files (or csv files, ideally). However, I'm having trouble with the binary to text conversion. Things I've tried looking at the binascii module. It doesn't appear clear to me that you can use this module to convert multiple-page files, only short strings. So, now, I'm thinking I should just open the file in utf-8 encoding and

问题 I get the following output when I disassembled a simple ARM binary file using the command "arm-linux-gnueabihf-objdump -d a.out" 00008480 <_start>: 8480: f04f 0b00 mov.w fp, #0 8484: f04f 0e00 mov.w lr, #0 8488: bc02 pop {r1} 848a: 466a mov r2, sp What do different columns represent here? For example, 8480 and f04f 0b00 (from the 2nd line of code) 回答1: The first column is the address of the code in memory. 0x8480 means the memory address of this piece of code is 0x8480 . The second column is
