> How to POST JSON data with Curl from Terminal/Commandline to Test Spring REST?17个
我在烧瓶中设置了一个非常简单的邮政路线:
from flask import Flask,request app = Flask(__name__) @app.route('/post',methods=['POST']) def post_route(): if request.method == 'POST': data = request.get_json() print('Data Received: "{data}"'.format(data=data)) return "Request Processed.\n" app.run()
这是我尝试从命令行发送的curl请求:
curl localhost:5000/post -d '{"foo": "bar"}'
但仍然打印出“收到的数据:”无“”.所以,它无法识别我传递的JSON.
在这种情况下是否有必要指定json格式?
解决方法
根据
get_json
文档:
[..] function will return
None
if the mimetype is notapplication/json
but this can be overridden by theforce
parameter.
因此,要么将传入请求的mimetype指定为application / json:
curl localhost:5000/post -d '{"foo": "bar"}' -H 'Content-Type: application/json'
或使用force = True强制进行JSON解码:
data = request.get_json(force=True)
如果在Windows上运行此命令(cmd.exe,而不是PowerShell),则还需要更改JSON数据的引用,从单引号到双引号:
curl localhost:5000/post -d "{\"foo\": \"bar\"}" -H 'Content-Type: application/json'
