class PyPDF2.PdfFileReader(stream, strict=True, warndest=None, overwriteWarnings=True)
Initializes a PdfFileReader object. This operation can take some time, as the PDF stream’s cross-reference tables are read into memory.
参数说明：
Parameters:
stream – A File object or an object that supports the standard read and seek methods similar to a File object. Could also be a string representing a path to a PDF file.
流，一个文件对象或是类似文件对象的支持标准的读和搜索方法的一个对象，也可以是一个代表了pdf文件路径的字符串
strict (bool) – Determines whether user should be warned of all problems and also causes some correctable problems to be fatal. Defaults to True.
严格（bool类型）确定是否应警告用户所有问题，并会导致一些可纠正的问题致命
warndest – Destination for logging warnings (defaults to sys.stderr).
警告目的 警告日志的记录目的，默认为sys.stderr
overwriteWarnings (bool) – Determines whether to override Python’s warnings.py module with a custom implementation (defaults to True).一些方法：
##decrypt(password)
When using an encrypted / secured PDF file with the PDF Standard encryption handler, this function will allow the file to be decrypted. It checks the given password against the document’s user password and owner password, and then stores the resulting decryption key if either password is correct.
It does not matter which password was matched. Both passwords provide the correct decryption key that will allow the document to be used with this library.
Parameters: password (str) – The password to match.
Returns: 0 if the password failed, 1 if the password matched the user password, and 2 if the password matched the owner password.
Return type: int
Raises NotImplementedError:
if document uses an unsupported encryption method.
##documentInfo
Read-only property that accesses the getDocumentInfo() function.
##getDestinationPageNumber(destination)
Retrieve page number of a given Destination object
Parameters: destination (Destination) – The destination to get page number. Should be an instance of Destination
Returns: the page number or -1 if page not found
Return type: int
##getDocumentInfo()
Retrieves the PDF file’s document information dictionary, if it exists. Note that some PDF files use metadata streams instead of docinfo dictionaries, and these metadata streams will not be accessed by this function.
Returns: the document information of this PDF file
Return type: DocumentInformation or None if none exists.
##getFields(tree=None, retval=None, fileobj=None)
Extracts field data if this PDF contains interactive form fields. The tree and retval parameters are for recursive use.
Parameters: fileobj – A file object (usually a text file) to write a report to on all interactive form fields found.
Returns: A dictionary where each key is a field name, and each value is a Field object. By default, the mapping name is used for keys.
Return type: dict, or None if form data could not be located.
##getFormTextFields()
Retrieves form fields from the document with textual data (inputs, dropdowns)
##getNamedDestinations(tree=None, retval=None)
Retrieves the named destinations present in the document.
Returns: a dictionary which maps names to Destinations.
Return type: dict
##getNumPages()

##namedDestinations
Read-only property that accesses the getNamedDestinations() function.
##numPages
Read-only property that accesses the getNumPages() function.
##outlines
Read-only property that accesses the
getOutlines() function.
