“实体仅允许使用JSON Content-Type标头进行写” Java OneDrive Jersey

标签: java json jersey content-type onedrive

我正在尝试使用OneDrive(https://docs.microsoft.com/en-us/onedrive/developer/rest-api/api/driveitem_post_content?view=odsp-graph-online)中的API上传文件。我正在使用Java和Jersey来执行此操作,但无法执行该操作。我从API得到了相同的响应(我一直在努力解决这一问题大约一个星期)。这是错误:

{
  "error": {
  "code": "BadRequest",
  "message": "Entity only allows writes with a JSON Content-Type header.",
  "innerError": {
      "request-id": "3c0ea4e0-cbcc-4f11-9ca3-fc3fbfdd50bc",
    "date": "2019-02-14T21:11:41"
    }
  }
}

让我分享我的代码:

 String metadataJson
    = "{"
    + "\"name\":\""+name+"\","
    + "\"file\":{},"
    + "\"@microsoft.graph.sourceUrl\":\"cid:content\","
    + "\"@microsoft.graph.conflictBehavior\":\"rename\""
    + "}";

FormDataContentDisposition fdcdMetadata =  FormDataContentDisposition.name("metadata").build();
FormDataBodyPart metadataPart = new FormDataBodyPart(fdcdMetadata, metadataJson, buildChildMultipart("application", "json", "metadata"));

    File tempFile = new File(this.temporaryFolderUri, tempFileName);
    FormDataContentDisposition fdcdContent = FormDataContentDisposition.name("content").build();
    FormDataBodyPart contentPart = new FormDataBodyPart(fdcdContent, tempFile, buildChildMultipart("plain", "text", "content"));
    MultiPart nestedMultipart = new MultiPart(buildParentMultipart())
            .bodyPart(metadataPart)
            .bodyPart(contentPart);

    return this.service.post(target, Entity.entity(nestedMultipart, nestedMultipart.getMediaType()));

。 。

public MediaType buildParentMultipart() {
    final Map<String, String> parameters = new HashMap<String, String>();
    parameters.put("boundary", "A100x");
    MediaType mediaType = new MediaType("multipart", "form-data", parameters);
    mediaType.withCharset("UTF-8");
    return mediaType;
}


public MediaType buildChildMultipart(String type, String  subType, String name) {
    final Map<String, String> parameters = new HashMap<String, String>();
    parameters.put("Content-ID", name);
    MediaType mediaType = new MediaType(type, subType, parameters);
    mediaType.withCharset("UTF-8");
    return mediaType;
}

现在发送发送请求的代码:

public JsonObject post(WebTarget target, Entity entity) throws InterruptedException, ExecutionException {
    return target.request(MediaType.APPLICATION_JSON).header(AUTHORIZATION_HEADER, getAccessToken())
            .header("Content-type", MediaType.APPLICATION_JSON)
            .header("accept", MediaType.APPLICATION_JSON)
            .buildPost(entity)
            .submit(JsonObject.class).get();
}

我在很多论坛中都在寻找任何解决方案,但是我没有运气。我在使用Node.js,C#和Javascript的项目中看到了相同的问题,但是在Java项目中(没有适用于Java的OneDrive SDK)却没有。我检查了标头,内容类型,边界,但似乎还可以。该问题似乎与元数据部分有关,但我正在设置MS要求的内容类型。你能帮我吗?谢谢你。
