[尝试获取添加的注释的文本时,我使用以下curl命令在flask.request.form中得到了关键错误。我尝试打印出flask.request.form,但是它是空的。如何解决?
curl命令添加新注释:
curl -ib cookies.txt
--header 'Content-Type: application/json'
--request POST
--data '{"text":"Comment sent from curl"}'
http://localhost:8000/api/v1/p/3/comments/
错误:
werkzeug.exceptions.BadRequestKeyError: 400 Bad Request: The browser (or proxy) sent a request that this server could not understand.
KeyError: 'text'
我的评论obj:
<form id="comment-form">
<input type="text" value=""/>
</form>
我的flask.api python文件,它将返回新的注释字典:
@app.route('/api/v1/p/<int:postid>/comments/', methods=["POST"])
def add_comment(postid):
db = model.get_db()
owner = flask.session["username"]
query = "INSERT INTO comments(commentid, owner, postid, text, created) VALUES(NULL, ?, ?, ?, DATETIME('now'))"
db.execute(query, (owner, postid, flask.request.form["text"]))
last_id = db.execute("SELECT last_insert_rowid()").fetchone()["last_insert_rowid()"]
get_newest_comment_query = "SELECT * FROM comments WHERE commentid = ?"
comment = db.execute(get_newest_comment_query, (last_id,)).fetchone()
print('get comment: ', comment)
return flask.jsonify(comment), 201
[添加到@Harshal的答案中,使用curl时,您好像访问了错误的请求数据。由于请求的内容类型设置为application/json
,因此您需要使用flask.request.json
-more details
或者您可以如下更新curl
命令,
curl -ib cookies.txt
--request POST
--data-urlencode "text=Comment sent from curl"
http://localhost:8000/api/v1/p/3/comments/
在这种情况下,curl将自动使用Content-Type application/x-www-form-urlencoded
,并且您的应用程序将能够使用flask.request.form
