decode

Using Swift4, iOS11.1, Xcode9.1, The following parseData method almost works. Everything seems to work fine (and a correct JSON-data set is fetched by this URLSession and JSONDecode). However, what is really surprising to me is the fact that a normal Browser shows different JSON-data (i.e. 20x as much is fetched than compared to this iOS-URLSession approach). Why is that ?? In the code below, you can find two print statements. The first showing the actual URLRequest-string (including all query- and type-parameters). The second prints the number of fetched JSON data-sets. If you use a Browser

第20条-用None和文档字符串来描述具有动态默认值的参数 关键: 1 参数的默认值 特点: 包含代码的模块一旦加载进来，参数的默认值就不变了 2 动态设置默认值 把默认值设置为None,如果发现参数的值为None,就设置为默认值 先看一个示例 def log1(content, when=datetime.utcnow()): print("content: {content}, when: {when}".format(content=content, when=when)) def log2(content, when=None): """ :param content: :param when: :return: """ when = datetime.utcnow() if when is None else when print("content: {}, when: {}".format(content, when)) def process(): log1('test1') time.sleep(1) log1('test2') print('=====') log2('test1') time.sleep(1) log2('test2') if __name__ == "__main__": process() #输出 content: test1, when:

I am using Preon to encode enum fields in a byte array. The fields of the first byte (example-byte: 0xf7=1111 01 11) are set up as this: @BoundNumber(size="2") //Corresponds to 11 private byte b1_1_notUsed; @BoundNumber(size="2") //Corresponds to 01 private ParkingBrakeSwitch parkingBrakeSwitch; @BoundNumber(size="4") private byte b1_3_notUsed; //Corresponds to 1111 Decoding works fine, thus I expect encoding the decoded object back to a byte array will yield the same byte array that I had from the beginning. This is not the case however. Instead the bits in the first byte are encoded like

I just test this sample from php doc ( http://au2.php.net/manual/en/function.json-decode.php ) here is my code: <?php $json = '{"a":1,"b":2,"c":3,"d":4,"e":5}'; echo json_decode($json, true), '<br />';?> But it just returns an EMPTY array. Have no idea why...Been searching around but no solution found. PLEASE help! you should not use echo because it is an array. use print_r or var_dump .it works fine $json = '{"a":1,"b":2,"c":3,"d":4,"e":5}'; print_r(json_decode($json, true)); Output: Array ( [a] => 1 [b] => 2 [c] => 3 [d] => 4 [e] => 5 ) You can validate at following website: http://jsonlint

1、UnicodeDecodeError: 'gbk' codec can't decode byte 0xaa in position 32: illegal multibyte sequence UnicodeDecodeError: 'gbk' codec can't decode byte 0xaa in position 132: illegal multibyte sequence 解决方案：尚未有 推测： 字符集合（   ） 问题出在“gbk"和”utf-8"都不能读取上面的那些（红色标注）字符，目前解决方法是找到文本中的这个字符，对其进行删除，再读取文本，或者使用try ……except 结构，凡是遇到读取失败的文本，continue 跳过，读取下一个文件。 2、SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 16-17: malformed \N character escape 解决方案：初步确认是文件路径的格式不对，filename应该为：E:/Python/Corpus/News/Environment/001.txt 这里是斜杆，而不是反斜杠 3、UnicodeDecodeError: 'utf-8' codec can't decode
