Java 改型2通过MS graph api发送邮件返回参数值'；消息'；是空的

我有一个JavaSpring项目，它使用Reformation2对来自Microsoft的GraphAPI进行API调用。我能够验证、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：包含邮件。发送

    private String[] scopes = [
            "openid",
            "email",
            "profile",
            "User.Read",
            "Mail.Read",
            "Mail.Send",
            "Mail.ReadWrite",
            "Calendars.Read",
            "Calendars.ReadWrite",
            "Contacts.Read",
            "Contacts.ReadWrite",
            "offline_access"
    ];

改装电话：

    @Headers("Content-Type: application/json")
    @POST("/v1.0/me/sendMail")
    Call<Message> sendMessage(
            @Body String messageObject
    );

"{\"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响应：

我认为，在实际发送json数据时，不应该使用双引号的转义字符

因此，发出的字符串应该是不可替换的，并且看起来像这样

{"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
收件人
的有效属性，您应该在
电子邮件地址
属性中
name
属性无效，应删除
ContentType
值可以是
text
或
html

因此，发出的json应该是这样的

{
  "Message": {
    "toRecipients": [
      {
        "emailAddress": {
            address:"test@test.be"
        }
      }
    ],
    "Body": {
      "ContentType": "html",
      "Content": "value(Email_body)=%3Cp%3Etesttext%3C%2Fp%3E"
    },
    "Subject": "testsubject"
  },
  "SaveToSentItems": "true"
}

您还可以通过以下链接阅读有关sendMail api的更多信息

所以我想，通过改型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
    );

@Headers（“内容类型：application/json”）
@POST（“/v1.0/me/sendMail”）
呼叫发送消息(
@Body HashMap messageObject
);
我在MS链接中尝试了该示例，但它返回了相同的错误。可能是改型调用出错了。您是否使用类似Gson的库构造json字符串对象？或者您只是将一个字符串作为参数传递给改造调用吗？我使用gson构建了json，但似乎改造2需要一个
HashMap
来将其发布为ure jsonHappy，很高兴听到您对其进行了整理。：）
