使用python通过Pinata API锁定目录

Question

我正在尝试使用pinata的API来固定整个目录，因为这是在他们的API documentation中指定的。

我也找到了some python implementation，但这对我来说似乎仍然不起作用。

基本上，我从目录中获取所有文件，并尝试将它们包含在post请求中。

all_files: tp.List[str] = get_all_files(filepath)            
files = {"file": [(file, open(file, "rb")) for file in all_files]}

response: requests.Response = requests.post(url=ipfs_url, files=files, headers=headers)

我得到的错误如下：

ValueError: too many values to unpack (expected 4)

我还尝试了一些硬编码的值，但仍然没有成功：

all_files = ['images/0.png', 'images/1.png', 'images/2.png']
files = {"file": [(file, open(file, "rb")) for file in all_files]}

response: requests.Response = requests.post(url=ipfs_url, files=files, headers=headers)

然而，在这种情况下，我得到了一个不同的错误：

TypeError: expected string or bytes-like object

同样，作为另一次尝试，我尝试了这样的东西：

files = (
    ("file", ("0.png", open('images/0.png', "rb"))),
    ("file", ("1.png", open('images/1.png', "rb")))
)

response: requests.Response = requests.post(url=ipfs_url, files=files, headers=headers)

在这种情况下，Pinata无法识别我想要的内容，并返回以下错误：

{'error': 'More than one file and/or directory was provided for pinning.'}

有人能给我一些提示吗?我哪里做错了？谢谢!

编辑:添加要使用的完整示例：

import os
import requests
import typing as tp

def get_all_files(directory: str) -> tp.List[str]:
    """get a list of absolute paths to every file located in the directory"""
    paths: tp.List[str] = []
    for root, dirs, files_ in os.walk(os.path.abspath(directory)):        
        for file in files_:            
             paths.append(os.path.join(root, file))
    return paths
    
  
print("hello")
# Example 1
all_files: tp.List[str] = get_all_files("images")            
files = {"file": [(file, open(file, "rb")) for file in all_files]}

# Example 2
#all_files = ['images/0.png', 'images/1.png', 'images/2.png']
#files = {"file": [(file, open(file, "rb")) for file in all_files]}

# Example 3
#files = (
#    ("file", ("0.png", open('images/0.png', "rb"))),
#    ("file", ("1.png", open('images/1.png', "rb")))
#)

print ("Files used: \n")
print (files)

headers = {        
    'pinata_api_key': "",
    'pinata_secret_api_key': ""     
}   

ipfs_url = "https://api.pinata.cloud/pinning/pinFileToIPFS"

response: requests.Response = requests.post(url=ipfs_url, files=files, headers=headers)
print(response.json())

Answer 1

好的，我设法上传了整个目录，并指定了如下文件：

files = [
        ('file', ('images/0.png', open('images/0.png', "rb"))),
        ('file', ('images/1.png', open('images/1.png', "rb"))),
    ]

因此，总的来说，为了收集所有文件并上传它们，我能够使用以下代码：

all_files: tp.List[str] = get_all_files(directory)            
files = [('file', (file, open(file, "rb"))) for file in all_files]
