CreateUser 使用 mongocxx 3.1.1 C++ 失败
CreateUser fails using mongocxx 3.1.1 C++
在 Windows 10 上使用 MongoDB 服务器 3.4.4,以下命令工作正常:
db.createUser(
{
user: "Billy",
pwd : "123456",
roles :
[
{ role: "userAdmin", db : "biolomics_index" },
{ role: "dbAdmin", db : "biolomics_index" },
{ role: "readWrite", db : "biolomics_index" }
]
}
运行 使用 mongocxx 3.1.1 C++ 驱动程序的相同命令失败:
db.run_command(document{} << "createUser" << open_document <<
"user" << "Billy" <<
"pwd" << "123456" <<
"roles" << open_array <<
open_document << "role" << "userAdmin" << "db" << "biolomics_index" << close_document <<
open_document << "role" << "dbAdmin" << "db" << "biolomics_index" << close_document <<
open_document << "role" << "readWrite" << "db" << "biolomics_index" << close_document <<
close_array << close_document <<
finalize);
错误:
"createUser" had the wrong type. Expected string, found object:
generic server error.
我找不到生成正确文档的语法。有什么想法吗?
根据 createUser
documentation,用户名应作为值 createUser
而不是 user
字段。将您的代码更改为:
db.run_command(document{} <<
"createUser" << "Billy" <<
"pwd" << "123456" <<
"roles" << open_array <<
open_document << "role" << "userAdmin" << "db" << "biolomics_index" << close_document <<
open_document << "role" << "dbAdmin" << "db" << "biolomics_index" << close_document <<
open_document << "role" << "readWrite" << "db" << "biolomics_index" << close_document <<
close_array <<
finalize);
注意:
正如 Saghm 在评论中提到的,MongoDB shell 助手与驱动程序中的 "run command" 等价物并不完全相同。如果您想尝试使用 database::run_command
中驱动程序所需的相同 BSON,您可以使用 shell 的 db.runCommand
。
- 从驱动程序中查询 Database Commands Manual 以获得可用的命令和参数。
