问题描述

我正在编写一个 python-flask api 来解析和操作 xml，使用 xml to dict.以下是我的初始代码:

I am writing a python-flask api to parse and manipulate xml using xml to dict. Below is my initial code:

from flask import Flask, jsonify, abort, make_response, request,
render_template
import sys, sqlite3, requests, datetime, time, re, json, optparse
import xmltodict
import helpers
import platform
app = Flask(__name__)

start = int(round(time.time()))
print("api running")

@app.route("/", methods=['GET', 'POST'])
def parse_xml():
    content_dict = xmltodict.parse(request.data)
    return content_dict

if __name__ == '__main__':
    print("Starting python app")
    app.run(host='0.0.0.0', port=8080, debug=False)

以下 curl 请求:curl -H "Authorization: Bearer Token" -X POST -d ''网址

The following curl request: curl -H "Authorization: Bearer Token" -X POST -d '<xml><From>Jack</From><Body>Hello, it worked!</Body></xml>' url

返回错误:

Any help would be appreciated, thank you.

推荐答案

您必须将 curl 请求更改为 key=value 对以便于处理.

You have to change you're curl request to be key=value pairs for easy handling.

卷曲:

 curl -H "Authorization: Bearer Token" -X POST -d 'SomeKey=<xml><From>Jack</From><Body>Hello, it worked!</Body></xml>' http://127.0.0.1:5000

蟒蛇:

from flask import Flask, jsonify, request
import xmltodict

app = Flask(__name__)

@app.route("/", methods=['GET', 'POST'])
def parse_xml():
    xml_data = request.form['SomeKey']
    content_dict = xmltodict.parse(xml_data)
    return jsonify(content_dict)

回复:

{
  "xml": {
      "Body": "Hello, it worked!",
      "From": "Jack"
  }
}
