Question

如何转换此命令：

curl -v -u abcdefghij1234567890:X -H "Content-Type: application/json" -X GET 'https://domain.freshdesk.com/api/v2/tickets'

到

Rcurl中的

curl命令？

Answer 1

curlconverter的开发版本（devtools::install_github("hrbrmstr/curlconverter")现在可以使用身份验证和详细参数转换curl命令行字符串：

将您的网址复制到剪贴板：

curl -v -u abcdefghij1234567890:X -H "Content-Type: application/json" -X GET 'https://domain.freshdesk.com/api/v2/tickets'

然后运行：

library(curlconverter)
req <- make_req(straighten())[[1]]

以下内容现在位于剪贴板中：

httr::VERB(verb = "GET", url = "https://domain.freshdesk.com/api/v2/tickets", 
    httr::authenticate(user = "abcdefghij1234567890", 
        password = "X"), httr::verbose(), 
    httr::add_headers(), encode = "json")

但req现在也是一个可调用的函数。你可以看到：

req
## function () 
## httr::VERB(verb = "GET", url = "https://domain.freshdesk.com/api/v2/tickets", 
##     httr::authenticate(user = "abcdefghij1234567890", password = "X"), 
##     httr::verbose(), httr::add_headers(), encode = "json")

或通过实际调用它：

req()

我通常会重新格式化函数源以使其更具可读性：

httr::VERB(verb = "GET", 
           url = "https://domain.freshdesk.com/api/v2/tickets", 
           httr::authenticate(user = "abcdefghij1234567890", password = "X"),
           httr::verbose(), 
           httr::add_headers(), 
           encode = "json")

您可以轻松将其转换为普通GET来电，而无需命名空间：

GET(url = "https://domain.freshdesk.com/api/v2/tickets", 
    authenticate(user = "abcdefghij1234567890", password = "X"), 
    verbose(), 
    add_headers(), 
    encode = "json"))

我们可以通过示例中的小替换验证它是否使用经过身份验证的curl命令行：

curl_string <- 'curl -v -u abcdefghij1234567890:X -H "Content-Type: application/json" -X GET "https://httpbin.org/basic-auth/abcdefghij1234567890/X"'

make_req(straighten(curl_string))[[1]]()

## -> Host: httpbin.org
## -> Authorization: Basic YWJjZGVmZ2hpajEyMzQ1Njc4OTA6WA==

## }

Answer 2

您可以使用httr执行此操作，如下所示：

require(httr)
GET('https://domain.freshdesk.com/api/v2/tickets',
    verbose(),
    authenticate("user", "passwd"),
    content_type("application/json"))
