错误请求错误 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/

这是下载一个文件，用于在私人仓库中更新exe。

我在使用 bitbucket 时经常收到 400 条错误。

我拥有的：

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

我想包括这个header

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

所以像这样：

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

应该修复吗？

至少根据....

"Some http client software expects to receive an authentication challenge before it will send an authorization header and this may mean that it may not behave as expected. In this case you may need to configure it to supply the authorization header as described above rather than relying on its default mechanism."

和...

但对我来说，即使进行了此更改 400 https://pastebin.com/V9ibxTRX（完整代码在这里或下面的简短版本）我总是会出错

可选的错误消息（它不是很漂亮，但我确实减少了它）：

Answer 1

我不熟悉你为 client object 使用的库，但你应该可以在你的 Content-Type header 中设置headers字典。

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（解压）到 urllib3.util.make_headers 并且它不接受 content_type 参数。

另外你不能访问 Client 中的 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 header 我不建议修改你的库的源代码，但如果你别无选择...
