我在使用 Flask 视图时遇到问题,该视图应返回内容类型为“application/json”的响应以响应 POST 请求。具体来说,如果我这样做:
curl -v -d 'foo=bar' http://example.org/jsonpost
对此观点:
@app.route('/jsonpost', methods=['GET', 'POST'])
def json_post():
resp = make_response('{"test": "ok"}')
resp.headers['Content-Type'] = "application/json"
return resp
我得到某种连接重置:
* About to connect() to example.org port 80 (#0)
* Trying xxx.xxx.xxx.xxx... connected
* Connected to example.org (xxx.xxx.xxx.xxx) port 80 (#0)
> POST /routing/jsonpost HTTP/1.1

相反,如果我这样做:
curl -d 'foo=bar' http://example.org/htmlpost
至:
@app.route('/htmlpost', methods=['GET', 'POST'])
def html_post():
resp = make_response('{"test": "ok"}')
resp.headers['Content-Type'] = "text/html"
return resp
我得到了预期的完整响应(200-ok)
{"test": "ok"}
顺便说一句,如果我向同一个 JSON 路由发送 GET 请求:
curl http://example.org/jsonpost
我也得到了预期的回应..有什么想法吗?
