我正在调用Paypal的REST API来获取访问令牌https://developer.paypal.com/docs/api/overview/#get-an-access-token
我正在使用带有superagent的节点来进行AJAX调用。
这是我的代码:
const basicAuth = Buffer.from(`${PAYPAL_CLIENT}:${PAYPAL_SECRET}`).toString('base64')
request
.post(PAYPAL_OAUTH_API)
.set('Accept', 'application/json')
.set('grant_type', 'client_credentials')
.set('Authorization', `Basic ${basicAuth}`)
.send()
.end((result) => {
console.log(result.response.error)
})
这是我遇到错误的日志
{ Error: cannot POST /v1/oauth2/token/ (400)

status: 400,

为什么我会得到错误的不支持的授予类型-授予类型为NULL? 在邮递员中,它可以工作,但是我无法使其与超级代理和节点一起工作。 Paypal给出了两个带有邮递员和curl的示例here。为什么不能与superagent一起使用?
答案 0 :(得分:1)
已链接到的Paypal文档:
如果您使用的不是cURL命令行工具,请将
Accept header
设置为application/x-www-form-urlencoded
已链接到superget
个文档中的文档:
默认情况下,发送字符串会将
Content-Type
设置为application/x-www-form-urlencoded
因此将您的请求更改为:
// PAYPAL_LINK = "https://api.sandbox.paypal.com"
// PAYPAL_OAUTH_API = "/v1/oauth2/token"
request(PAYPAL_LINK)
.post(PAYPAL_OAUTH_API)
.send('grant_type=client_credentials')
.auth(PAYPAL_CLIENT, PAYPAL_SECRET)
.then(response => console.log(response))
.catch(error => console.error(error))
如果您希望将响应设置为Accept: application/json
,则可选地设置json
