BadRequest: 400 Bad Request: The browser (or proxy) sent a request that this server could not understand

BadRequest是一个HTTP状态码，表示客户端发送的请求存在语法错误，服务器无法理解。具体地，400 Bad Request表示浏览器（或代理）发送了一个服务器无法理解的请求。这个错误通常发生在请求的语法格式有误的情况下。在你提供的引用中，400 Bad Request错误表明在前端传递参数时存在错误，导致服务器无法理解请求。此错误可能是由于参数错误或格式错误导致的[2]。在Flask中，当使用request.form获取不到对应的参数时，也会返回400错误。因此，如果使用POST请求，并且参数为JSON数据，最好使用request.get_json()方法来接收参数，而不是使用request.form。另外，要确保参数的语法格式正确，以避免出现BadRequest错误。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
