无法使用 httr 包连接到 Qualtrics API

我正在尝试使用 Rstudio Cloud“httr”包连接到 Qualtrics API 以下载邮件列表。查看 API 文档后，我无法下载数据，运行代码后出现以下错误：

"{"meta":{"httpStatus":"400 - Bad Request","error":{ “errorMessage”：“标头中预期有授权，但没有提供。","errorCode":"ATP_2"},"requestId":"8fz33cca-f9ii-4bca-9288-5tc69acaea13"}}"

这对我来说没有任何意义，因为我使用的是继承身份验证父令牌。这是代码：

    install.packages("httr")

    library(httr)

    directoryId<-"POOL_XXXXX"
    mailingListId <- "CG_XXXXXX"
    apiToken<-"XXXX"


    url<- paste("https://iad1.qualtrics.com/API/v3/directories/",directoryId,
             "/mailinglists/",mailingListId,"/optedOutContacts", sep = "")

   response <- VERB("GET",url, add_headers('X_API-TOKEN' = apiToken), 
   content_type("application/octet-stream"))

   content(response, "text")

任何帮助将不胜感激。

提前致谢。

I am trying to connect to Qualtrics API using Rstudio Cloud "httr" package to download mailing lists. After a review of the API documentation I was unable to download the data, getting the following error after running the code:

"{"meta":{"httpStatus":"400 - Bad Request","error":{"errorMessage":"Expected authorization in headers, but none provided.","errorCode":"ATP_2"},"requestId":"8fz33cca-f9ii-4bca-9288-5tc69acaea13"}}"

This does not makes me any sense since I am using a inherit auth from parent token. Here is the code:

    install.packages("httr")

    library(httr)

    directoryId<-"POOL_XXXXX"
    mailingListId <- "CG_XXXXXX"
    apiToken<-"XXXX"


    url<- paste("https://iad1.qualtrics.com/API/v3/directories/",directoryId,
             "/mailinglists/",mailingListId,"/optedOutContacts", sep = "")

   response <- VERB("GET",url, add_headers('X_API-TOKEN' = apiToken), 
   content_type("application/octet-stream"))

   content(response, "text")

Any help will be appreciated.

Thanks in advance.

您对 httr::VERB 的调用将 API 令牌和内容类型分解为函数的两个参数，但它们应该在向量中一起传递给单个“config”参数。此外，content_type 不是一个函数，它只是该标头向量中元素的名称。这应该有效：

response <- VERB("GET", url, add_headers(c(
                               'X_API-TOKEN' = apiToken, 
                               'content_type' = "application/octet-stream")))

请注意，Qualtrics 将返回邮件列表作为列表，其中将包含“meta”元素和“result”元素，这两个元素本身都是列表。如果列表很长，则仅返回列表中的前100个联系人；将有一个元素response$result$nextpage，它将提供访问接下来的100个结果所需的URL。 qualtRics::fetch_mailinglist() 函数不适用于XM Directory 联系人列表（这可能就是您在使用它时收到 500 错误的原因），但是用于解压列表并循环每个“nextpage”元素的代码可能会有所帮助。

Your call to httr::VERB breaks the API token and the content type into two arguments to the function, but they should be passed together in a vector to a single "config" argument. Also, content_type isn't a function, it's just the name of an element in that header vector. This should work:

response <- VERB("GET", url, add_headers(c(
                               'X_API-TOKEN' = apiToken, 
                               'content_type' = "application/octet-stream")))

Note that mailing lists will be returned by Qualtrics as lists that will include both a "meta" element and a "result" element, both of which will themselves be lists. If the list is long, the only the first 100 contacts on the list will be returned; there will be an element response$result$nextpage that will provide the URL required to access the next 100 results. The qualtRics::fetch_mailinglist() function does not work with XM Directory contact lists (which is probably why you got a 500 error when using it), but the code for unpacking the list and looping over each "nextpage" element might be helpful.
