from flask import Flask, make_response app = Flask(__name__) def hello(): return "Hello World!" app.add_url_rule('/hello', view_func = hello) if __name__ == '__main__': app.run(debug=True)
這裏是返回 status code, content-type(在headers中默認是text/html),因此當return ''時無回顯,以下面,訪問這個,會跳轉到百度html
from flask import Flask, make_response app = Flask(__name__) def hello(): # status code # content-type(http headers text/html) headers = { 'content-type':'text/plain', 'location':'http://baidu.com' } #response = make_response('<html></html>', 301) #response.headers = headers #return response return '<html></html>', 301, headers #return "<html></html>" def helloo(): return "Hello World!" app.add_url_rule('/hello', view_func = hello) if __name__ == '__main__': app.run(debug=True)
編寫一個書籍搜索,我這裏先實現搜索分類,書籍搜索含關鍵字和isbn編號搜索,isbn分爲isbn10 isbn13 前者有'-',0-9組成,後面有0-9數字組成python
from flask import Flask app = Flask(__name__) @app.route('/book/search/<q>/<page>') def search(q, page): """ q (isbn13 0-9 isbn10'-') page """ isbn_or_key = 'key' if len(q) == 13 and q.isdigit(): isbn_or_key = 'isbn' short_q = q.replace('-', '') if '-' in q and len(short_q) == 10 and short_q.isdgit: isbn_or_key = 'isbn' pass if __name__ == '__main__': app.run()
