我们从Python开源项目中,提取了以下19个代码示例,用于说明如何使用binascii.a2b_hqx()。
def read(self, totalwtd): """Read at least wtd bytes (or until EOF)""" decdata = '' wtd = totalwtd # # The loop here is convoluted, since we don't really now how # much to decode: there may be newlines in the incoming data. while wtd > 0: if self.eof: return decdata wtd = ((wtd+2)//3)*4 data = self.ifp.read(wtd) # # Next problem: there may not be a complete number of # bytes in what we pass to a2b. Solve by yet another # loop. # while 1: try: decdatacur, self.eof = \ binascii.a2b_hqx(data) break except binascii.Incomplete: pass newdata = self.ifp.read(1) if not newdata: raise Error, \ 'Premature EOF on binhex file' data = data + newdata decdata = decdata + decdatacur wtd = totalwtd - len(decdata) if not decdata and not self.eof: raise Error, 'Premature EOF on binhex file' return decdata
