烧瓶问题和错误请求 [英] Problems with flask and bad request

问题描述

我正在为自己编程一个非常好的 api，以使用 json 从我的游戏服务器获取一些 json 数据到我的网站空间，

I was programming myself a pretty nice api to get some json data from my gameserver to my webspace using json,

但每次我使用 angular 发送请求时，我都会收到:127.0.0.1 - - [20/Mar/2018 17:07:33] 代码 400，消息请求版本错误 ("▒\x9c▒▒{▒'\x12\x99▒▒▒\xadH\x00\x00\x14▒+▒/▒,▒0▒\x13▒\x14\x00/\x005\x00")127.0.0.1 - - [20/Mar/2018 17:07:33] "▒\x9dtTc▒\x93▒4▒M▒▒▒▒▒\x9c▒▒\x9c▒▒{▒'\x99▒▒▒▒▒▒▒▒▒▒/▒,▒0▒▒/5" HTTPStatus.BAD_REQUEST -127.0.0.1 - - [20/Mar/2018 17:07:33] 代码 400，消息错误请求语法 ('\x16\x03\x01\x00▒\x01\x00\x00\x9d\x03\x03▒k,&▒▒ua\x8c\x82\x17\x05▒QwQ$▒0▒▒\x9f▒B1\x98\x19W▒▒▒▒\x00\x00\x14▒+▒/103,\x14\x00/\x005\x00')127.0.0.1 - - [20/Mar/2018 17:07:33] "▒\x9d▒k,&▒▒ua\x8c\x82▒QwQ$▒0▒▒\x9f▒B1\x98W▒\x98W▒▒+▒/▒,▒0▒▒/5" HTTPStatus.BAD_REQUEST -127.0.0.1 - - [20/Mar/2018 17:07:33] 代码 400，消息错误请求语法 ('\x16\x03\x01\x00▒\x01\x00\x00▒\x03\x03)▒▒\x1e\xa0▒\t\r\x14g%▒▒\x17▒▒\x80\x8d}▒F▒▒\x08U▒ġ▒▒\x06▒\x00\x00\x1c▒+,▒▒▒/')g%▒▒▒▒\x80\x8d}▒F▒U▒ġ▒▒▒▒+▒/▒,▒0▒" HTTPStatus.BAD_REQUEST -

我的接口

from flask import Flask, jsonify
from flaskext.mysql import MySQL
from flask_cors import CORS, cross_origin

app = Flask(__name__)
CORS(app)
app.config['CORS_HEADERS'] = 'Content-Type'
cors = CORS(app, resources={r"/punishments": {"origins": "http://localhost:5000" "*"}})
mysql = MySQL()

# MySQL configurations
app.config['MYSQL_DATABASE_USER'] = 'test'
app.config['MYSQL_DATABASE_PASSWORD'] = 'Biologie1'
app.config['MYSQL_DATABASE_DB'] = 'test'
app.config['MYSQL_DATABASE_HOST'] = 'localhost'

mysql.init_app(app)

@app.route('/punishments', methods=['GET'])
@cross_origin(origin='localhost:5000',headers=['Content- Type','Authorization'])
def get():
    cur = mysql.connect().cursor()
    cur.execute('''select * from test.punishments''')
    r = [dict((cur.description[i][0], value)
              for i, value in enumerate(row)) for row in cur.fetchall()]
    return jsonify({'punishments' : r})

if __name__ == '__main__':
    app.run()

我的客户端功能

export class ApiUserService {

  private _postsURL = "https://localhost:5000/punishments";

  constructor(private http: HttpClient) {
  }

  getPosts(): Observable<Punishments[]> {

    let headers = new HttpHeaders();
    headers = headers.set('Content-Type', 'application/json; charset=utf-8');

    return this.http
      .get(this._postsURL,{
        headers: {'Content-Type':'application/json; charset=utf-8'}
      })
      .map((response: Response) => {
        return <Punishments[]>response.json();
      })
      .catch(this.handleError);
  }

  private handleError(error: Response) {
    return Observable.throw(error.statusText);
  }
}

推荐答案

我遇到了和你一样的错误.

I had the same error as yours.

我的 Flask 服务器安装在 respberry-pi 中，我试图使用 https://ip:5000 访问它.

My flask server was installed inside respberry-pi and I was trying to access it using https://ip:5000.

问题是我使用的是 https 而不是 http.

The problem was I was using https instead of http.

当我将其更改为 http://ip:5000 时，它起作用了.

When I changed it to http://ip:5000, it worked.
