Flask Api解析返回错误的xml post请求

标签: python xml curl flask xmltodict

我正在编写一个python-flask api来使用xml解析和操作xml来进行dict。以下是我的初始代码:

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)

以下卷曲请求:curl -H "Authorization: Bearer Token" -X POST -d '<xml><From>Jack</From><Body>Hello, it worked!</Body></xml>' url

返回错误:

您必须将您的curl请求更改为key = value对,以便于处理。

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

的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"
  }
}

您还可以将curl用于post XML文件内容:

curl -X POST -d @data.xml  -H 'Accept: application/xml'  -H 'Content-Type: application/xml' url

data.xml内容:

<xml>
 <From>Jack</From>
 <Body>Hello, it worked!</Body>
</xml>
