错误的请求错误 400

Question

我想用客户端配置复制以下内容。

Curl -D- -X GET -H "Authorization: Basic ZnJlZDpmcmVk" -H "Content-Type: application/json" http://localhost:7990/rest/api/1.0/projects
https://developer.atlassian.com/server/bitbucket/how-tos/example-basic-authentication/

这是在私人仓库中下载用于更新 exe 的文件。

我在使用 bitbucket 时经常遇到 400 个错误。

我有什么：

client = Client(ClientConfig(), headers={'basic_auth':'U:P' }, refresh=True)

我想包含这个标题

header = {'Content-Type': 'application/json'}

比如：

client = Client(ClientConfig(), headers={'basic_auth': 'brofewfefwefewef:EKAXsWkdt5H6yJEmtexN'}, header = {'Content-Type': 'application/json'}, refresh=True)

应该修复吗？

至少根据....

“某些 http 客户端软件在发送授权标头之前希望收到身份验证质询，这可能意味着它可能无法按预期运行。在这种情况下，您可能需要将其配置为提供上述授权标头而不是依赖其默认机制。”

还有……

但对我来说，即使更改 400 https://pastebin.com/V9ibxTRX （此处为完整代码或以下简短版本），我总是会出错

可选的错误消息（它不漂亮，但我确实减少了它）：

我不熟悉您用于 client 对象的库，但您应该能够在 headers 字典中设置 Content-Type 标头。

headers = {
    'basic_auth': 'brofewfefwefewef:EKAXsWkdt5H6yJEmtexN', 
    'Content-Type': 'application/json'
}
client = Client(ClientConfig(), headers=headers, refresh=True)

不幸的是，这似乎是不可能的，因为 headers 被传递（解包）到 urllib3.util.make_headers 并且它不接受 content_type 参数。

您也不能在Client 中访问FileDownloader._http.headers，因为它是一个局部变量。
一个可能的FileDownloader'hack'：

class FileDownloader(object):
    ...Line 152...
    def _get_http_pool(self, secure=True):
        if secure:
            _http = urllib3.PoolManager(cert_reqs=str('CERT_REQUIRED'), 
                                        ca_certs=certifi.where())
        else:
            _http = urllib3.PoolManager()

        if self.headers:
            content_type = self.headers.get('Content-Type') 
            if 'Content-Type' in self.headers:
                del self.headers['Content-Type']
            _headers = urllib3.util.make_headers(**self.headers)
            _http.headers.update(_headers)
            if content_type:
                _http.headers['content-type'] = content_type
        print(_http.headers)
        return _http

这应该允许您在 Client 中传递 Content-Type 标头。
我不建议修改你的库的源代码，但如果你别无选择......
