【问题描述】：

我在我的 django 项目中使用 paypal sdk 制作 paypal 发票时遇到了一点问题。当我尝试执行此代码时

invoice_id = ''
    invoice = Invoice({
        "merchant_info": {
            "email": '',  # You must change this to your sandbox email account
            "first_name": str(merchant.first_name),
            "last_name": str(merchant.last_name),
            "business_name": str(merchant_full_name),
            "phone": {
                "country_code": "001",
                "national_number": str(merchant.phone)
            },
            "address": {
                "line1": str(merchant_address.address),
                "city": str(merchant_address.city),
                "state": str(merchant_address.state),
                "postal_code": str(merchant_address.zip_code),
                "country_code": "US"
            }
        },
        "billing_info": [{"email": buyer.paypal_address}],
        "items": [
            {
                "name": "Slab",
                "quantity": 1,
                "unit_price": {
                    "currency": "USD",
                    "value": float(slab.price)
                }
            }
        ],
        "note": "Invoice for slab",
        "payment_term": {
            "term_type": "NET_45"
        },
        "shipping_info": {
            "first_name": buyer.first_name,
            "last_name": buyer.last_name,
            "business_name": str(buyer_full_name),
            "phone": {
                "country_code": "001",
                "national_number": str(buyer.phone)
            },
            "address": {
                "line1": str(buyer_address.address),
                "city": str(buyer_address.city),
                "state": str(buyer_address.state),
                "postal_code": str(buyer_address.zip_code),
                "country_code": "US"
            }
        },
        "shipping_cost": {
            "amount": {
                "currency": "USD",
                "value": 0
            }
        }
    })

    if invoice.create():
        print(json.dumps(invoice.to_dict(), sort_keys=False, indent=4))
        invoice_id = invoice['id']
        return invoice_id
    else:
        print(invoice.error)

我的服务器将这些错误返回给我

据我了解，这是贝宝令牌的问题，对吧？

【问题讨论】：

在提出这个问题之前，您进行了哪些研究、尝试、迭代等工作？如果您怀疑这是一个令牌问题，您做了什么来确认或否认该断言？
@dfundako 如果我在消息中看到 Unauthorized 这个词，那么我明白是令牌的问题，但我不知道如何解决它

【解决方案1】：

您需要验证您的请求：

import requests, base64

# you can only encode byte objects
credentials = b"userid:password"
b64Val = base64.b64encode(credentials)
r=requests.post(api_URL, 
    headers={"Authorization": "Basic %s" % b64Val},
    data=payload)
