我试图与pCloud API交友，在Bash中使用curl，

创建pCloud应用程序并获取其$clientid和$clientsecret之后，我可以在以下站点获得接受请求的临时访问令牌：

echo "https://my.pcloud.com/oauth2/authorize?client_id=$clientid&response_type=code"

在给定$temptok令牌时，我将使用以下内容获得永久承载令牌：

permtok=$(curl "https://api.pcloud.com/oauth2_token?client_id=$clientid&client_secret=$clientsecret&code=$temptok" | jq -r '.access_token')

此时，我可以使用他们的API方法，发布这里。

例如，用户信息或列表文件夹方法，它提供：

curl "https://api.pcloud.com/userinfo?access_token=$permtok"
curl "https://api.pcloud.com/listfolder?access_token=$permtok&path=/"

但是，我无法下载文件。根据我的理解，我需要使用打开和朗读的组合，而后者需要文件大小。当我打开一个文件时，我会得到一个类似于以下内容的输出：

curl "https://api.pcloud.com/file_open?access_token=$permtok&path=/foo.txt&flags=0x0040"                      
{
    "result": 0,
    "fd": 1,
    "fileid": 1234567890
}

当对file_size方法使用文件描述符时：

curl "https://api.pcloud.com/file_size?access_token=$permtok&fd=1"

我知道错误：

{
    "result": 1007,
    "error": "Invalid or closed file descriptor."
}

下载文件的正确方法是什么？

curl

cloud-storage

pcloud

下载文件的概述命令

我可以通过浏览器下载带有getfolderpublink链接的文件。

curl可以下载文件。但pCloud网站上并没有记载这一点。我是通过浏览器调试窗口(F12)找到的。

我知道下载API也不是真正的下载。它只获取文件的元数据。

https://api.pcloud.com/getfilelink?fileid={my-file-id}&auth={my-auth}'

Curl下载文件

curl -o {download-file-name} -L -X GET 'https://p-def7.pcloud.com/{full path of my file}' \
-H "Content-Type: application/json; charset=utf-8" \
-H "Authorization: Bearer $token"

演示

1得到8月ID

https://my.pcloud.com/oauth2/authorize?client_id={my_client_id}&response_type=code

2获取访问令牌& Auth代码

https://u.pcloud.com/oauth2/authorize?client_id=9xxxxxx7&response_type=code&auth={auth_id}

Auth代码很重要，Access Token也很重要

auth=wt9xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxgX

使用代码获取访问令牌。

curl -L -X POST 'https://api.pcloud.com/oauth2_token' \
-H 'Content-Type: application/json; charset=utf-8' \
--form 'client_id="9xxxxxxx7"' \
--form 'client_secret="4xxxxxxxxxxxxxxxxX"' \
--form 'code="lKxxxxxxxxxxxxxxxxxxX"'

响应

{
    "result": 0,
    "userid": 18905223,
    "locationid": 1,
    "token_type": "bearer",
    "access_token": "lKxxxxxxxxxxxxxx-My-Token-xxxxxxxxxxxxxxxxxG7"
}

3在终端指定带有令牌名称的环境变量。

$ token="lKxxxxxxxxxxxxxx-My-Token-xxxxxxxxxxxxxxxxxG7"

4通过获取列表-文件夹API获取文件信息

我将下载一个文件Getting started with pCloud.pdf，我需要从JSON响应中获取fileid。"fileid“是43338896472

curl -L -X GET 'https://api.pcloud.com/listfolder?path=/' \
-H "Content-Type: application/json; charset=utf-8" \
-H "Authorization: Bearer $token" | jq

{
  "result": 0,
  "metadata": {
    "path": "/",
    "name": "/",
    "created": "Sat, 17 Sep 2022 23:58:07 +0000",
    "ismine": true,
    "thumb": false,
    "modified": "Sat, 17 Sep 2022 23:58:07 +0000",
    "id": "d0",
    "isshared": false,
    "icon": "folder",
    "isfolder": true,
    "folderid": 0,
    "contents": [
.... other three default directories
      {
        "name": "Getting started with pCloud.pdf",
        "created": "Sat, 17 Sep 2022 23:58:07 +0000",
        "videocodec": "",
        "thumb": false,
        "modified": "Sat, 17 Sep 2022 23:58:07 +0000",
        "size": 16371465,
        "audiobitrate": 0,
        "fps": "0.00",
        "comments": 0,
        "isfolder": false,
        "height": 0,
        "rotate": 0,
        "fileid": 43338896472,
        "videobitrate": 0,
        "width": 0,
        "hash": 3096725505949383000,
        "duration": "0.00",
        "path": "/Getting started with pCloud.pdf",
        "category": 4,
        "audiosamplerate": 0,
        "id": "f43338896472",
        "isshared": false,
        "ismine": true,
        "audiocodec": "mp3",
        "parentfolderid": 0,
        "contenttype": "application/pdf",
        "icon": "document"
      }
    ]

5通过stat API获取文件信息(包括文件大小)

curl -L -X GET 'https://api.pcloud.com/stat?fileid=43338896472' \
-H "Content-Type: application/json; charset=utf-8" \
-H "Authorization: Bearer $token" | jq

{
  "result": 0,
  "metadata": {
    "name": "Getting started with pCloud.pdf",
    "created": "Sat, 17 Sep 2022 23:58:07 +0000",
    "videocodec": "",
    "thumb": false,
    "modified": "Sat, 17 Sep 2022 23:58:07 +0000",
    "size": 16371465,
    "audiobitrate": 0,
    "fps": "0.00",
    "comments": 0,
    "isfolder": false,
    "height": 0,
    "rotate": 0,
    "fileid": 43338896472,
    "videobitrate": 0,
    "width": 0,
    "hash": 3096725505949383000,
    "duration": "0.00",
    "category": 4,
    "audiosamplerate": 0,
    "id": "f43338896472",
    "isshared": false,
    "ismine": true,
    "audiocodec": "mp3",
    "parentfolderid": 0,
    "contenttype": "application/pdf",
    "icon": "document"
  }
}

6得到getfilepublink API

在JSON响应中获取link信息

"link": "https://u.pcloud.link/publink/show?code=XZ9xxxxxxxxxxsss6Sk"

curl -L -X GET 'https://api.pcloud.com/getfilepublink?fileid=43338896472' \
-H "Content-Type: application/json; charset=utf-8" \
-H "Authorization: Bearer $token" | jq

{
  "code": "XZ9bBhVZ0lSVBSVb4jJKDXJAJBBJ0FIOs6Sk",
  "created": "Sun, 18 Sep 2022 01:15:38 +0000",
  "downloadenabled": true,
  "type": 1,
  "modified": "Sun, 18 Sep 2022 01:15:38 +0000",
  "downloads": 1,
  "link": "https://u.pcloud.link/publink/show?code=XZ9xxxxxxxxxxsss6Sk", <- I modified the code
  "result": 0,
  "linkid": 60017201,
  "haspassword": false,
  "traffic": 16371465,
  "views": 20,
  "metadata": {
    "name": "Getting started with pCloud.pdf",
    "created": "Sat, 17 Sep 2022 23:58:07 +0000",
    "videocodec": "",
    "thumb": false,
    "modified": "Sat, 17 Sep 2022 23:58:07 +0000",
    "size": 16371465,
    "audiobitrate": 0,
    "fps": "0.00",
    "comments": 0,
    "isfolder": false,
    "height": 0,
    "rotate": 0,
    "fileid": 43338896472,
    "videobitrate": 0,
    "width": 0,
    "hash": 3096725505949383000,
    "duration": "0.00",
    "category": 4,
    "audiosamplerate": 0,
    "id": "f43338896472",
    "isshared": false,
    "ismine": true,
    "audiocodec": "mp3",
    "parentfolderid": 0,
    "contenttype": "application/pdf",
    "icon": "document"
  }
}

7得到下载元数据API -步骤6部分的相同结果

8获取文件路径和主机URL

Host name数组将取决于文件的属性(默认文件或个人文件)。

curl -L -X GET 'https://api.pcloud.com/getfilelink?fileid=43338896472&auth=wt9xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxgX' \
-H "Content-Type: application/json; charset=utf-8" \
-H "Authorization: Bearer $token"

{
    "result": 0,
    "dwltag": "GYYEgtilNwytpYulbsh1UB",
    "hash": 3096725505949383041,
    "size": 16371465,
    "expires": "Sun, 18 Sep 2022 10:53:50 +0000",
    "path": "\/cfZRj4OT2Zwk45bAZlKxxxxxxxxxxxxxxxxxxZbRZlJZ0JZKXZmpZSHZY7ZsFZzpZS5ZLa6pViVfwjfcge2gksnF08W9Qwi7\/Getting%20started%20with%20pCloud.pdf",
    "hosts": [
        "p-def7.pcloud.com",
        "c432.pcloud.com"
    ]
}

最后，我可以用步骤8下载主机名和路径。

full URL = Host[0] name + path (删除前两个字符\ /)

curl -o guide.pdf -L -X GET 'https://p-def7.pcloud.com/cfZRj4OT2Zwk45bAZlKxxxxxxxxxxxxxxxxxxZbRZlJZ0JZKXZmpZSHZY7ZsFZzpZS5ZLa6pViVfwjfcge2gksnF08W9Qwi7\/Getting%20started%20with%20pCloud.pdf' \
-H "Content-Type: application/json; charset=utf-8" \
-H "Authorization: Bearer $token"

我可以通过浏览器二下载。
