我正在尝试 Google Cloud Spanner 的“Python 中的 Cloud Spanner 入门”指南。

我已经创建了实例数据库等

我已经到了“创建数据库客户端”部分。

我们在防火墙后面操作并且必须设置我们的代理设置，我们已经使用 Gsutil、BQ 命令行等成功完成了这项工作

当我设置代理设置然后尝试执行 quickstart.py 我得到错误。

E0620 08:35:32.703000000  5020 src/core/ext/filters/client_channel/uri_parser.c:60] bad uri.scheme: 'xx.xxx.xxx.xxx:xx'

E0620 08:35:32.703000000  5020 src/core/ext/filters/client_channel/uri_parser.c:66]                  ^ here

E0620 08:35:32.703000000  5020 src/core/ext/filters/client_channel/http_proxy.c:56] cannot parse value of 'http_proxy' env var

这是在database.execute_sql('SELECT 1')一切都出错的地方。

如果您还没有看过快速入门示例，这里是代码。

def run_quickstart():
# [START spanner_quickstart]
# Imports the Google Cloud Client Library.
from google.cloud import spanner

# Instantiate a client.
spanner_client = spanner.Client()

# Your Cloud Spanner instance ID.
instance_id = 'im-spanner'

# Get a Cloud Spanner instance by ID.
instance = spanner_client.instance(instance_id)

# Your Cloud Spanner database ID.
database_id = 'd42'

# Get a Cloud Spanner database by ID.
database = instance.database(database_id)

# Execute a simple SQL statement.
results = database.execute_sql('SELECT 1')

for row in results:
    print(row)
# [END spanner_quickstart]


if __name__ == '__main__':
    run_quickstart()

我已经仔细检查了代理详细信息，它们是正确的。任何人都可以帮忙吗？

您是否将 http_proxy 变量设置为指向您的代理？有关信息，请参阅https://github.com/grpc/grpc/blob/master/doc/environment_variables.md。如果您使用使用 gRPC 的云库通过 Proxy 访问，则需要设置此变量以提供 Proxy 的 URI 给 gRPC 库。
