我尝试过：

PartitionKey partitionKey = new PartitionKey("/sid");

CosmosItemRequestOptions options = new CosmosItemRequestOptions();

cosmosContainer.deleteItem("dbs/Student/colls/Stu/docs/104", partitionKey, options);

但是出现错误：

SEVERE: locationEndpoint is null because ClientRetryPolicy::onBeforeRequest(.) is not invoked, probably request creation failed due to invalid options, serialization setting, etc.

2 个答案:

答案 0 :(得分：0)

传递给deleteItem方法的参数在您的代码段中不正确。

参数：

第一个参数 itemId ：应为文档ID 。您通过了整个层次结构路径。

第二个参数 partitionKey ：它应包含分区键的值。我猜你通过了字段名称。

例如，您可以参考this example以获得正确的用法。

答案 1 :(得分：0)

cosmosContainer.deleteItem（“”，新的PartitionKey（），选项）;

您可以删除options参数，因为您没有配置它。

cosmosContainer.deleteItem（“”，新的PartitionKey（））;
