处理Json请求时出错
我发送一个json请求并捕获python flask服务中的请求参数以进一步处理。 但是，当我json转储请求并尝试从它收集特定的参数值时，它给我错误
“字符串索引必须是整数，而不是str”
这是我在python烧瓶中分析的json：
{"description": "URL: https://sometest.xyz.com/test16/apicalln Issue: sample issuen Result: failn Severity: lown Category: sample category", "issuetype": {"name": "Bug"}, "priority": {"name": "Trivial"}, "project": "sample-project", "summary": "sample issue - https://sometest.xyz.com/test16/apicall"}
我无法弄清楚我在做什么错。
这是我的python烧瓶代码：
from flask import Flask
from flask import request
from flask import json
import httplib
httplib.HTTPConnection.debuglevel = 2
app = Flask(__name__)
@app.route('/', methods=['POST','GET'])
def main():
_jsonreq = json.dumps(request.json)
return _jsonreq['project']
if __name__ == "__main__":
app.run(debug=True)
您正在为_jsonreq分配JSON字符串，但随后尝试将其用作字典。 尝试将您的代码更改为：
@app.route('/', methods=['POST','GET'])
def main():
_jsonreq = request.json
return _jsonreq['project']
