我正在尝试在 O365 的帮助下发送电子邮件。我已经配置了所有内容，但出现错误

GraphError { statusCode: 405, code: 'Request_BadRequest',
message: 'Specified HTTP method is not allowed for the request target.', requestId: '34f321-57de-4483-b97d-5957f8786ecb', date: 2019-09-16T00:17:53.000Z, body: '{"code":"Request_BadRequest","message":"Specified HTTP method is not allowed for the request target.","innerError":{"request-id":"34f803b1-57de-4483-b97d-5957f8786ecb","date":"2019-09-16T05:47:51"}}' }

        }, 
        saveToSentItems: "false" 
    }; 
 
    client.api('/users/test1@abc.onmicrosoft.com ').post(sendMail).then((res) => { 
        console.log(res); 
    }).catch((err) => { 
        console.log(err); 
    }); 
} 

有人可以告诉我哪里出了问题吗？请帮帮我

请您参考如下方法:

我遇到了同样的错误，发送给用户时这是一个格式错误的网址。

我认为您的网址应该是 /users/test1@abc.onmicrosoft.com/sendMail
