Question

我正在尝试使用HttpPost请求通过Web应用程序创建会议，但出现400 BadRequest错误，并显示消息“ onlinemeeting不能为null。”

HttpPost httpPost = new HttpPost("https://graph.microsoft.com/v1.0/me/onlineMeetings");
        
LocalDateTime meetingTime = java.time.LocalDateTime.now();
        
try {
    JSONObject bodyJson = new JSONObject();
        
    bodyJson.put("meetingType", "meetNow"); //tried with and without this and still didn't work
    bodyJson.put("startDateTime", meetingTime.toString());
    bodyJson.put("subject", "TeamsMeeting");
    bodyJson.put("participants", new JSONObject().put("organizer", 
            new JSONObject().put("identity", 
                    new JSONObject().put("user", 
                            new JSONObject().put("id", userId)))));
    
    StringEntity entity = new StringEntity(bodyJson.toString());
    entity.setContentType("application/json");
    httpPost.setEntity(entity);
            
    BasicHeader authHeader = new BasicHeader("Authorization", "Bearer " + teamsToken);
    httpPost.addHeader(authHeader);
    httpPost.addHeader("Content-Type", "application/json");
        
            
    HttpResponse postResponse = httpClient.execute(httpPost);
    String responseContent = EntityUtils.toString(postResponse.getEntity(), StandardCharsets.UTF_8.name());
...

我在执行发布请求时得到了这个信息：

{
    "error": {
        "code":"BadRequest",
        "message":"onlinemeeting cannot be null.",
        "innerError": {
            "date":"2020-07-10T19:09:48",
            "request-id":"cfad7871-6595-4efb-a262-13ac42f0e599"
        }
    }
}

当我使用邮递员时它可以工作，但是当我通过网络应用程序点击它时却不能。任何想法可能是什么原因造成的？ Java代码有什么问题吗？任何帮助表示赞赏。

如果您使用用户令牌创建在线会议，则MS Graph中的OnlineMeeting中有IGraphServiceClient graphClient = GraphServiceClient.builder().authenticationProvider( authProvider ).buildClient(); OnlineMeeting onlineMeeting = new OnlineMeeting(); onlineMeeting.startDateTime = "2019-07-12T21:30:34.2444915+00:00"; onlineMeeting.endDateTime = "2019-07-12T22:00:34.2464912+00:00"; onlineMeeting.subject = "User Token Meeting"; graphClient.me().onlineMeetings() .buildRequest() .post(onlineMeeting);的Java。

IGraphServiceClient graphClient = GraphServiceClient.builder().authenticationProvider( authProvider ).buildClient();

OnlineMeeting onlineMeeting = new OnlineMeeting();
onlineMeeting.startDateTime = "2019-07-12T21:30:34.2444915+00:00";
onlineMeeting.endDateTime = "2019-07-12T22:00:34.2464912+00:00";
onlineMeeting.subject = "Application Token Meeting";

MeetingParticipants meetingParticipants = new MeetingParticipants();
meetingParticipants.organizer.identity.user.id = "550fae72-d251-43ec-868c-373732c2704f";
onlineMeeting.participants = meetingParticipants;


graphClient.me().onlineMeetings()
.buildRequest()
.post(onlineMeeting);

如果您使用应用令牌创建在线会议，请尝试以下代码：

OnlineMeeting

有关类using UnityEngine; public class BikeController : MonoBehaviour { public float speed = 1500; public float rotationSpeed = 10f; public WheelJoint2D backWheel; public WheelJoint2D frontWheel; public Rigidbody2D rb; private float movement = 0f; private float rotation = 0f; public Transform player; void Update() { movement = Input.GetAxisRaw("Horizontal") * speed; rotation = Input.GetAxisRaw("Vertical"); if (Input.touchCount > 0) { Touch tch = Input.GetTouch(0); if (tch.position.x > player.position.x) { movement = speed; } if (tch.position.x < player.position.x) { movement = -speed; } } } void FixedUpdate() { if (movement == 0f) { backWheel.useMotor = false; frontWheel.useMotor = false; } else { backWheel.useMotor = true; frontWheel.useMotor = true; JointMotor2D motor = new JointMotor2D { motorSpeed = movement, maxMotorTorque = 10000 }; backWheel.motor = motor; frontWheel.motor = motor; } rb.AddTorque(rotation * rotationSpeed * Time.fixedDeltaTime); } }的更多详细信息，请参见doc。

使用以下代码对我有用：

        OkHttpClient client = new OkHttpClient();
        MediaType mediaType = MediaType.parse("application/json");
        RequestBody body = RequestBody.create(mediaType, json);
        Request request = new Request.Builder()
          .url(authHelper.getMsGraphEndpointHost() + url)
          .post(body)
          .addHeader("content-type", "application/json")
          .addHeader("authorization", accessToken)
          .addHeader("cache-control", "no-cache")
          .build();

        Response responseOk = client.newCall(request).execute();

Answer 3

问题最终出在了startDateTime上，因为我认为它的格式不正确。该错误消息并未表明它是该值，但是一旦将其从json主体中删除，它就可以工作，而不必使用OnlineMeeting对象。

MS Graph创建的团队遇到错误请求“ onlinemeeting不能为空”。
