Flask's request and response objects

Some of the properties of the Request and Response objects are metadata, some are parsed, and others are just links.

Request

• methodStart Row, metadata
• hostStart Row, metadata
• pathStart Row, metadata
• environWhere SERVER_PROTOCOL is the starting row, the meta-data
• headersheader, Meta data
• dataBody, meta data
• remote_addrClient Address
• argsParameters in the request link (GET parameters), after parsing
• formParameters in form submission, after parsing
• valuesThe collection of args and forms
• jsonBody data in JSON format, after parsing
• cookiesLinks to Cookies

The Request object classifies the parameters very fine, note args , form , valeus and json the difference. Of course the most insurance and the most primitive way is to resolve themselves data .

Another area to be aware of is the type of some attributes, not the Python standard dict , but multidict or combinedmultidict. This is to deal with the setting that the parameters in the HTTP protocol are repeatable. So pay attention to the properties of these objects, such as the .get() .get_list() things returned by the method.

Response

• statusStatus code, meta data
• status_codeContains only the status of code
• headersheader, Meta data
• mimetypeRemove the content type of charset, such asapplication/json
• dataBody, meta data
