Python eve使用curl命令发布列表媒体文件失败，返回422

Question

我使用pythoneve构建我的restfulapi，我在设置.py，如下所示：

risks = {
    'schema': {
        'description': {
            'type': 'string',
            'required': True,
        },
        'pic': {
            'type': 'list',
            'schema': {
                'type': 'media',
            }
        },
    }
}

我尝试使用curl命令将两个jpg文件发布到'pic'字段，如下所示：

^{pr2}$

但得到这样的422错误：

{"_status": "ERR", "_issues": {"pic": "must be of list type"}, "_error": {"message": "Insertion failure: 1 document(s) contain(s) error(s)", "code": 422}}%

我能做什么，我只试过一种媒体（不是列表类型），没问题，为什么？ 有人能帮我吗？在

Answer 1

当您访问risks端点时，您需要提供正确的数据类型，以便资源端点正常工作。它会抱怨您发送的pic，因为它仍然是一个字符串而不是一个列表。在

您可以使用requests使您的生活更轻松

import requests

url = 'http://127.0.0.1:8080/risks'
data = {description : 'something', 'pic' : ['a','b','c','d']}
r = requests.post(url, json=data)

You can make your life a bit easier by using requests

如何将文件传递给请求jsonkwarg？作为文件处理？还是绳子？

当我尝试这个的时候

import requests
url = 'http://localhost:5000/tests'
data = {
    'icons': [
        open('/home/test/git-projects/test.com/backend/fixtures/media/test1.jpg').read(), #  If I pass the handle, it fails as well.
        open('/home/test/git-projects/test.com/backend/fixtures/media/test2.jpg').read()
    ]
}
r = requests.post(url, json=data)
