无法使用标准代码从 Python API 访问和下载 Sentinel-2 图像

Question

rec = POLYGON ((597843.23 2977645.792070312, 686175.1025585937 2977645.792070312, 686175.1025585937 3112308.537736816, 597843.23 3112308.537736816, 597843.23 2977645.792070312))
products = api.query(rec,
                     date = ('20191001', '20191031'),
                     platformname = 'Sentinel-2',          
                     cloudcoverpercentage = (0,40)
                    )

以上代码下载 sentinel-2 图像，出现以下错误：

KeyError                                  Traceback (most recent call last)
/usr/local/lib/python3.6/dist-packages/sentinelsat/sentinel.py in _load_subquery(self, query, order_by, limit, offset)

    394             json_feed = response.json()["feed"]
--> 395             if json_feed["opensearch:totalResults"] is None:
    396                
# We are using some unintended behavior of the server that a null is

KeyError: 'opensearch:totalResults'

During handling of the above exception, another exception occurred:

SentinelAPIError                          Traceback (most recent call last)
3 frames
/usr/local/lib/python3.6/dist-packages/sentinelsat/sentinel.py in _load_subquery(self, query, order_by, limit, offset)

    401             total_results = int(json_feed["opensearch:totalResults"])
    402         except (ValueError, KeyError):
403          raise SentinelAPIError("API response not valid. JSON decoding failed.", response)
    404 
    405         products = json_feed.get("entry", [])

SentinelAPIError: HTTP status 200 OK: API response not valid. JSON decoding failed.

我已阅读文档并参考了关于相同错误的类似问题，但无法解决问题。

您的多边形值不是坐标

Blockquote

rec = POLYGON ((597843.23 2977645.792070312, 686175.1025585937 2977645.792070312, 686175.1025585937 3112308.537736816, 597843.23 3112308.537736816, 597843.23 2977645.792070312))

您需要用经纬度值来描述多边形。
