python - 通过他们的 API 访问 Lending Club Loan 列表

Question

我正在尝试通过此处提供的官方 API 从 Lending Club 获取贷款 list :https://www.lendingclub.com/developers/listed-loans.action

我正在使用 python 'requests' 模块进行调用，下面是我尝试的代码:

    import requests
    header = {'Authorization' : 'xxxxxxxxxxxxxxxxxxxxxxxxxxxx', 'Content-Type': 'application/json', 'Accept': 'application/json', "X-LC-LISTING-VERSION":"1.1"}
    resp = requests.get("https://api.lendingclub.com/api/investor/v1/loans/listing", headers= header, params = {'showAll':'true'})

得到回应:

    resp.status_code
    401

我通过 R httr 包尝试了这里的解决方案，如 stackoverflow 问题中所述:Lending Club API with R ，但得到相同的 401 Unauthorized 响应。

还做了一个快速的 cURL 来检查我是否做错了什么。

    curl -v -i --header "Authorization:xxxxxxxxxxxxxxxxxxxxxxxxxxxx" --header "Accept:application/json" --header "Content-Type:application/json" --header "X-LC-LISTING-VERSION:1.1" -d "{"query": {"showAll": "true"}}" -XGET https://api.lendingclub.com/api/investor/v1/loans/listing

下面是我得到的转储:

似乎我在 API 调用中遗漏了某些内容，或者 Lending Club API 中未正确记录某些内容。

如果我能得到有关如何解决此问题的指示，那就太好了。

谢谢!

编辑:

我不知道发生了什么，但我登录了 Lending Club 帐户 --> 刷新了身份验证 key 并进行了 API 调用，它开始工作了。不过，解决这个问题的方式很奇怪。

Answer 1

以防万一有人想尝试，我们可以使用以下方法:

1. 在 R 中使用 httr

   图书馆(httr)结果 <- GET("https://api.lendingclub.com/api/investor/v1/loans/listing ", add_headers(.headers = c("Content-Type"="application/json","Accept"="application/json", "授权"="身份验证 key ")))输出<-内容(结果)

2. 使用请求，与问题中的类似。

3. 使用 curl 检查，与问题中的 cURL 实现相同。

但在执行所有这些操作之前，请确保您已通过浏览器登录到您的 Lending Club 帐户。
