使用url，我正在获取没有查询的端点。但是，在控制台上，我收到此错误。

    Error in "User-Agent":"Mozilla/5.0 (Macintosh; Intel Mac OS X 10.11; rv:58.0) Gecko/20100101 Firefox/58.0" : 
  NA/NaN argument
In addition: Warning messages:
1: In request(headers = c(..., .headers)) : NAs introduced by coercion
2: In request(headers = c(..., .headers)) : NAs introduced by coercion

我的GET请求有什么问题？我是否正确编码了？

Answer 1

错误来自于:序列运算符与字符串的使用。

c("a":"b")
Error in "a":"b" : NA/NaN argument
In addition: Warning messages:
1: NAs introduced by coercion 
2: NAs introduced by coercion

add_headers期待命名值，因此您应该使用：

add_headers(
    "User-Agent" = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.11; rv:58.0) Gecko/20100101 Firefox/58.0",
...
)

错误：NA / NaN参数
