Question

我想使用cURL将文件发布到Flask视图。但是，我得到400错误的响应。为什么下面的命令失败？

@app.route('/deploy/partial', methods=['POST'])
def postfile():
    try:
        file = request.files['file']
        filename = secure_filename(file.filename)
        file.save(os.path.join('/home/test/test.txt', filename))
        return 'OK', 200
    except:
        print("Unexpected error:", sys.exc_info()[0])
        raise

curl -X POST -H "Content-Type: multipart/form-data" -F "file=@FILEPATH" http://127.0.0.1:25252/deploy/partial

Unexpected error: <class 'werkzeug.exceptions.HTTPException.wrap.<locals>.newcls'>

我得到了

意外错误：.newcls＆＃39;＆gt;

我意外地将request.form [＆＃39; name＆＃39;]重命名为request.form [＆＃39; ame＆＃39;] （注意错误的＆＃39; ame＆＃39;）而我的表格字段是 name = StringField（...）

我将request.form [＆＃39; ame＆＃39;]更改为request.form [＆＃39; name＆＃39;]，错误消失，即烧瓶工作

不确定这是否也是你的情况。

使用cURL将文件发布到Flask会返回400错误
