@app.route('/sheets/api',methods=["POST"])
def insert():
if request.get_json():
return "<h1>Works! </h1>"
else:
return "<h1>Does not work.</h1>"
结果是不起作用
添加内容类型标题时:
我得到一个400错误
我做错了什么?您没有发布有效的JSON。JSON字符串使用双引号: 使用单引号时,字符串不是有效的JSON,返回400错误的请求响应 针对仅实现路由的本地Flask服务器的演示:
>>> import requests
>>> requests.post('http://localhost:5000/sheets/api', data="{'key':'value'}", headers={'content-type': 'application/json'}).text
'<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">\n<title>400 Bad Request</title>\n<h1>Bad Request</h1>\n<p>The browser (or proxy) sent a request that this server could not understand.</p>\n'
>>> requests.post('http://localhost:5000/sheets/api', data='{"key":"value"}', headers={'content-type': 'application/json'}).text
'<h1>Works! </h1>'
