如何使用Google Drive REST AP和HTTPClient创建文件夹？ [英] How to create a Folder with Google Drive REST AP and HTTPClient?

问题描述

我使用Google Drive REST API和HTTPClient创建文件夹。
REST API的文档此处请请注意，REST AP请求执行 - 但使用了错误的数据：tt创建了一个名为untitled的新文件，并将我的json放在那里。

我尝试了不同的方法使用HTTPClient构建POST请求，并成功执行 - 但不知何故，Google Drive响应创建文件并返回此数据，并忽略我提交的POST数据。

是什么服务器响应

..

kind：drive＃file，
id：0B -fYJN-c4UDjUlh1TUZadF9vejA，这是一个有效的ID
title：Untitled，----错误的标题
mimeType：application / json; charset = UTF-8 - 这是错误的mimeType
..

我尝试了以下调用API的方式：我不确定发生了什么事与帖子一起发送。
$ b $ 1 使用表单名称值对

$ p $ DefaultHttpClient httpClient = new DefaultHttpClient（）;
HttpPost postRequest = new HttpPost（https://www.googleapis.com/upload/drive/v2/files?key=+ GoogleClientConstants.GOOGLE_api_key）;

postRequest.addHeader（Authorization，Bearer+ accessToken）;
postRequest.addHeader（Content-Type，application / json; charset = UTF-8）;


List< NameValuePair> nvps = new ArrayList< NameValuePair>（）;
nvps.add（new BasicNameValuePair（title，vip））;
nvps.add（new BasicNameValuePair（mimeType，application / vnd.google-apps.folder））;
postRequest.setEntity（new UrlEncodedFormEntity（nvps，org.apache.http.Consts.UTF_8））;
HttpResponse response = httpClient.execute（postRequest）;


<2>使用StringEntity

  JSONObject jo = new JSONObject（）; 
 jo.element（title，pets）。element（mimeType，application / vnd.google-apps.folder）; 
 
 
 $ b ContentType contentType = ContentType.create（application / json，Charset.forName（UTF-8））; 
 StringEntity entity = new StringEntity（jo.toString（），contentType）; 
 
 logger.info（sending+ jo.toString（））; 
 
 
 postRequest.setEntity（entity）; 
 
 
 HttpResponse response = httpClient.execute（postRequest）; 
  

在这两种情况下，Google API都会响应200以及上述返回的FileResource。

解决方案

我用你的代码创建了一个小例子。对我而言，一切正常。请查看我的源代码：

  import org.apache.http.client.methods.HttpPost; 
 import org.apache.http.entity.StringEntity; 
 import org.apache.http.impl.client.DefaultHttpClient; 
 
 import com.google.gson.JsonObject; 
 
 public class SourceCodeProgram {
 
 public static void main（String argv []）throws Exception {
 DefaultHttpClient httpClient = new DefaultHttpClient（）; 
 HttpPost post = new HttpPost（
https://www.googleapis.com/drive/v2/files）; 
 post.addHeader（Content-Type，application / json）; 
 post.addHeader（Authorization，
Bearer XXXXXXXXXXXXXXXXXXXXXXXXX）; 
 
 JsonObject jsonObject = new JsonObject（）; 
 jsonObject.addProperty（title，Test folder）; 
 jsonObject 
 .addProperty（mimeType，application / vnd.google-apps.folder）; 
 
 post.setEntity（new StringEntity（jsonObject.toString（）））; 
 httpClient.execute（post）; 
 
 
  

以上代码不会引发任何异常。我已经检查了我的云端硬盘，并且可以看到其中的测试文件夹。你在网址中输入的关键是什么？

为什么你不使用 Google云端硬盘客户端库在您的应用中？

I am using Google Drive REST API with HTTPClient to create a folder. The REST API is document here Please note that the REST AP Request executes -- but uses the wrong data: tt creates a new file called "untitled" and puts my json there.

I have tried different methods of building the POST request with HTTPClient which execute successfully -- but somehow the Google Drive responds with creating a file and returns this data and ignores POST data that I submit.

This is what the server reponds with
..

"kind": "drive#file", "id": "0B-fYJN-c4UDjUlh1TUZadF9vejA", this is a valid ID "title": "Untitled", ----wrong title "mimeType": "application/json; charset=UTF-8", -- this is the wrong mimeType ..

I have tried the following ways of invoking the API : I am not sure what is happening to the data I am sending with the post.

1) Using form name value pairs

DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost postRequest = new HttpPost("https://www.googleapis.com/upload/drive/v2/files?key="+GoogleClientConstants.GOOGLE_api_key);

postRequest.addHeader("Authorization", "Bearer " + accessToken);
postRequest.addHeader("Content-Type", "application/json; charset=UTF-8");


List <NameValuePair> nvps = new ArrayList <NameValuePair>();
nvps.add(new BasicNameValuePair("title", "vip"));
nvps.add(new BasicNameValuePair("mimeType", "application/vnd.google-apps.folder"));
postRequest.setEntity(new UrlEncodedFormEntity(nvps, org.apache.http.Consts.UTF_8 ));
HttpResponse response = httpClient.execute(postRequest);

2) Using StringEntity

JSONObject jo= new JSONObject();
jo.element("title", "pets").element("mimeType", "application/vnd.google-apps.folder");



ContentType contentType= ContentType.create("application/json", Charset.forName("UTF-8")) ;
StringEntity entity = new StringEntity(jo.toString(), contentType); 

logger.info(" sending "+ jo.toString());


postRequest.setEntity(entity);


HttpResponse response = httpClient.execute(postRequest);

In both cases , Google API responds with 200 and the above mentioned returned FileResource.

解决方案

I've created a little example, using your code. And for me everything works OK. Please, see my source code:

import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.DefaultHttpClient;

import com.google.gson.JsonObject;

public class SourceCodeProgram {

    public static void main(String argv[]) throws Exception {
        DefaultHttpClient httpClient = new DefaultHttpClient();
        HttpPost post = new HttpPost(
                "https://www.googleapis.com/drive/v2/files");
        post.addHeader("Content-Type", "application/json");
        post.addHeader("Authorization",
                "Bearer XXXXXXXXXXXXXXXXXXXXXXXXX");

        JsonObject jsonObject = new JsonObject();
        jsonObject.addProperty("title", "Test folder");
        jsonObject
                .addProperty("mimeType", "application/vnd.google-apps.folder");

        post.setEntity(new StringEntity(jsonObject.toString()));
        httpClient.execute(post);
    }
}

Above code doesn't throw any exception. I've checked my Drive and I can see 'Test folder' in it. What the key are you putting in post URL?

Why are you not using Google Drive Client Library in your app?
