我正在编写一个 python-flask api 来解析和操作 xml，使用 xml to dict。下面是我的初始代码:
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 '<xml><From>Jack</From><Body>Hello, it worked!</Body></xml>' url
返回错误:

如有任何帮助，我们将不胜感激。
最佳答案
您必须将您的 curl 请求更改为键=值对以便于处理。
curl :
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
python :
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)
响应:
{
"xml": {
"Body": "Hello, it worked!",
"From": "Jack"
}
}
