我有一个JavaSpring项目，它使用Retrofit 2从微软API调用图形API。我能够进行身份验证，阅读邮箱和检索/阅读电子邮件。然而，我正在努力发送邮件。
我有以下发送电子邮件的代码：
权限：包含Mail. send
private String[] scopes = [
"openid",
"email",
"profile",
"User.Read",
"Mail.Read",
"Mail.Send",
"Mail.ReadWrite",
"Calendars.Read",
"Calendars.ReadWrite",
"Contacts.Read",
"Contacts.ReadWrite",
"offline_access"
];
改造电话：
@Headers("Content-Type: application/json")
@POST("/v1.0/me/sendMail")
Call<Message> sendMessage(
@Body String messageObject
);
发送的字符串是JSONString：
"{\"Message\":{\"toRecipients\":[{\"address\":\"test@test.be\",\"name\":\"test@test.be\"}],\"Body\":{\"ContentType\":\"text/html\",\"Content\":\"value(Email_body)=%3Cp%3Etesttext%3C%2Fp%3E\"},\"Subject\":\"testsubject\"},\"SaveToSentItems\":\"true\"}"
HTTP回应：

}
}
}

知道是什么导致了错误吗？
我相信当json数据实际发送时，您不应该使用双引号的转义字符。
因此，发出的字符串应该是未转义的，看起来像这样。
{"Message":{"toRecipients":[{"address":"test@test.be","name":"test@test.be"}],"Body":{"ContentType":"text/html","Content":"value(Email_body)=%3Cp%3Etesttext%3C%2Fp%3E"},"Subject":"testsubject"},"SaveToSentItems":"true"}
此外，你会发现
地址不是toRecipients的有效属性，您应该在emailAddress属性name属性无效，应删除。ContentType值可以是text或html因此，发出的json应该看起来像这样。
{
"Message": {
"toRecipients": [
{
"emailAddress": {
address:"test@test.be"
}
}
],
"Body": {
"ContentType": "html",
"Content": "value(Email_body)=%3Cp%3Etesttext%3C%2Fp%3E"
},
"Subject": "testsubject"
},
"SaveToSentItems": "true"
}
您还可以在以下链接中阅读有关sendMail api的更多信息
https://learn.microsoft.com/en-us/graph/api/user-sendmail?view=graph-rest-1.0
所以我想通了，用改造2发布原始json的正确方法是：
@Headers("Content-Type: application/json")
@POST("/v1.0/me/sendMail")
Call<Message> sendMessage(
@Body HashMap<String, Object> messageObject
);
