使用Java上传Onedrive API文件

Question

我正在尝试使用POST REST调用将文件上载到OneDrive文件夹中。我的应用程序能够与OneDrive通信。我得到的回复是The request entity body isn't a valid JSON object.

下面是我的代码，请让我知道代码的错误部分或我的方法。

public static void onedriveFileUpload() {
        CloseableHttpClient httpClient = HttpClients.createDefault();
        HttpPost uploadFile = new HttpPost("https://apis.live.net/v5.0/folder.id");
        MultipartEntityBuilder builder = MultipartEntityBuilder.create();
        uploadFile.addHeader("Authorization", "Bearer access_token");
        builder.addPart("file", new FileBody(new File("Test.txt"), ContentType.APPLICATION_OCTET_STREAM, "Test.txt"));
        builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
        Charset chars = Charset.forName("utf-8");
        builder.setCharset(chars);
        uploadFile.setEntity(builder.build());
        uploadFile.setHeader("Content-Type", "multipart/form-data");
        uploadFile.setHeader("charset", "UTF-8");
        uploadFile.setHeader("boundary", "AaB03x");
        HttpResponse response = null;
    try {
        response = httpClient.execute(uploadFile);
        HttpEntity responseEntity = response.getEntity();
        String json = EntityUtils.toString(responseEntity);
        System.out.println(json);
    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    }

以下是我从OneDrive收到的Json回复。

{
   "error": {
      "code": "request_body_invalid", 
      "message": "The request entity body isn't a valid JSON object."
   }
}

您应该POSThttps://apis.live.net/v5.0/:albumId/files/:fileName[.：format]。请尝试使用ByteArrayEntity而不是MultipartEntity。示例：

public Photo uploadPhoto(String accessToken, String albumId, String format, byte[] bytes) throws IOException {
    Photo newPhoto = null;
    URI uri;
    try {
        uri = new URIBuilder().setScheme(DEFAULT_SCHEME)
                              .setHost(API_HOST)
                              .setPath("/" + albumId + "/files/" + 
                                       UUID.randomUUID().toString() + "." + format)
                              .addParameter("access_token", accessToken)
                              .addParameter("downsize_photo_uploads", "false")
                              .build();
    } catch (URISyntaxException e) {
        e.printStackTrace();
        throw new IllegalStateException("Invalid album path");
    }
    CloseableHttpClient httpClient = HttpClients.createDefault();
    try {
        HttpPut httpPut = new HttpPut(uri);
        ByteArrayEntity imageEntity = new ByteArrayEntity(bytes);
        httpPut.setEntity(imageEntity);
        Map<Object, Object> rawResponse = httpClient.execute(httpPut, new SomeCustomResponseHandler());
        if (rawResponse != null) {
            newPhoto = new Photo();
            newPhoto.setName((String) rawResponse.get("name"));
            newPhoto.setId((String) rawResponse.get("id"));
            // TODO:: Do something else.
        }
    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        httpClient.close();
    }
    return newPhoto;
}

该代码是OneDrive4J中的一个片段。查看https://github.com/nicknux/onedrive4j.今年早些时候，当我试图寻找OneDrive Java客户端时，我构建了这个。

如果要使用POST方法，则需要POST到/api.live.net/v5.0/folder.id/files。您的代码在文件夹ID后面缺少/files部分。如果您仍然有问题，显示实际HTTP请求的跟踪会很有帮助。
