我正在尝试发布以下 JSON 并将其保存到 Flask 服务器和 Python 2.7、restless 框架和带有 curl 的 SQLAlchemy 上的 MySQL 数据库:
curl -i -H "Accept: application/json" -X POST -d '{"attribute_id": "1", "product_id": "44","text":"Something","language":"1"}' http://seroney-pc:5000/api/attributes
{
"attribute_id": "1",
"product_id": "44",
"text": "Something",
"language": "1"
}
我的代码如下:
from flask import Flask,request,jsonify, abort
from flask_sqlalchemy import SQLAlchemy
import flask_restless
app = Flask(__name__)
db = SQLAlchemy(app)
manager = flask_restless.APIManager(app)
app.config['SQLALCHEMY_DATABASE_URI'] = 'mysql://root:seroney@localhost:3306/test'
class Attributes(db.Model):
__tablename__ = 'oc_product_attribute'
product_id = db.Column(db.Integer,primary_key=True)
attribute_id = db.Column(db.Integer,primary_key=True)
language_id = db.Column(db.Integer,primary_key=True)
text=db.Column(db.String)
@app.route('/api/attributes/',methods=['GET'])
def getProductAttributes():
if request.method =='GET':
results = Attributes.query.limit(10).offset(0).all()
json_results = []
for result in results:
d = {
'product_id':result.product_id,
'attribute_id':result.attribute_id,
'language_id':result.language_id,
'text':result.text
}
json_results.append(d)
return jsonify(items = json_results)
@app.route('/api/attributes/', methods=['POST'])
def postProductAttributes():
product_id = request.json['product_id']
attribute_id = request.json['attribute_id']
language_id = request.json['language_id']
text = request.json['text']
if product_id is None or attribute_id is None or language_id is None or text is None:
return jsonify({"message": "Error."}), 400
new_attrib = (product_id,attribute_id,language_id,text)
db.session.add(new_attrib)
db.session.commit()
return jsonify({'message' :'Attribute Created successfully'}), 200
if __name__ == '__main__':
app.run(debug=True)
当我发布时,我不断收到内部服务器错误。非常感谢任何帮助。
