Is Base64_encode() in PHP equal to java.util.Base64?

由 隐身守侯 提交于 2019-12-13 09:39:18
问题 I want to use php to pass and get a encoded string to other system which are using java.util.Base64 to encode and decode. Can I use base64_encode($str) to encode and pass the string to them for decode in php and can i use base62_decode($str) to decode what I get from java.util.Base64 in php? Or is there other way to encode and decode java.util.Base64 string in php? Thanks!! 回答1: Short Answer: Yes . Base64 is a standard. Long Answer: The PHP documentation for base64_encode references RFC 2045

How to decode binary file with “ for index, line in enumerate(file)”?

由 我怕爱的太早我们不能终老 提交于 2019-12-13 09:33:51
问题 I am opening up an extremely large binary file I am opening in Python 3.5 in file1.py : with open(pathname, 'rb') as file: for i, line in enumerate(file): # parsing here However, I naturally get an error because I am reading the file in binary mode and then creating a list of bytes. Then with a for loop, you are comparing string to bytes and here the code fails. If I was reading in individual lines, I would do this: with open(fname, 'rb') as f: lines = [x.decode('utf8').strip() for x in f

问题 i have a encoded dataframe. I encode it with the labelEncoder from scitkit-learn, create a machine learning model and done some predictions. But now i cannot decode the values in the pandas dataframe for the outputs. I tried it several times with inverse_transform from the doc but still i get everytime errors like ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()` Thats what my dataframe look like: 0 147 14931 9 0 0 1 0 0 0 4 ... 0 0 242

Base64的编码(Encode)与解码(Decode)？java

关于base64编码Encode和Decode编码的几种方式 Base64 是一种能将任意Binary资料用64种字元组合成字串的方法，而这个Binary资料和字串资料彼此之间是可以互相转换的，十分方便。在实际应用上，Base64除了能将Binary资料可视化之外，也常用来表示字串加密过后的内容。如果要使用Java 程式语言来实作Base64的编码与解码功能，可以参考本篇文章的作法。 早期作法 早期在Java上做Base64的编码与解码，会使用到JDK里sun.misc套件下的BASE64Encoder和BASE64Decoder这两个类别，用法如下： final BASE64Encoder encoder = new BASE64Encoder(); final BASE64Decoder decoder = new BASE64Decoder(); final String text = "字串文字" ; final byte [] textByte = text.getBytes( "UTF-8" ); //编码 final String encodedText = encoder.encode(textByte); System.out.println(encodedText); //解码 System.out.println( new String(decoder

问题 I'm working on an IMAP email script and I have some lines coded in GB2312 (which I assume is Chinese encoding), looks like this =?GB2312?B?foobarbazetc How can I start working with this string? I checked mb_list_encodings() and this one is not listed. 回答1: If you have the base64-decoded data, then use mbstring or iconv. If you have the raw header, then mbstring. <?php $t = "\xc4\xe3\xba\xc3\n"; echo iconv('GB2312', 'UTF-8', $t); echo mb_convert_encoding($t, 'UTF-8', 'GB2312'); mb_internal
