Question

拜托，你能帮我弄清楚签名有什么问题吗？我真的，无法理解这是什么问题。我一直在寻找答案超过一个月。如果你给我一个类似工作的例子请求或帮助我理解这个问题我会非常感激！

library(RCurl)
library(httr)
library(rvest)

cons_key<-"ae1dd19212a84c4299f4b157462d32d7"
shared_secret<-"c0bc9938ea754f4ba6e926865b347fae"

encoded_url<-URLencode("http://platform.fatsecret.com/rest/server.api",reserved = T,repeated = T)
encoded_string<-URLencode("method=GET&oauth_consumer_key=cons_key&oauth_nonce=asdas4&oauth_signature_method=HMAC-SHA1&oauth_timestamp=15138110238&oauth_version=1.0",reserved = T,repeated = T)
text_string<-paste0("GET&",encoded_url,"&",encoded_string)

signature_oauth<-sha1_hash(key = "ae1dd19212a84c4299f4b157462d32d7&",string = text_string)

getForm("http://platform.fatsecret.com/rest/server.api",
    method="GET",
    oauth_consumer_key=cons_key,
    oauth_signature=signature_oauth,
    oauth_signature_method="HMAC-SHA1",
    oauth_timestamp="1513811023",
      oauth_nonce="asdas4",
    oauth_version="1.0",.opts = list(verbose = TRUE))

答案是：

 Trying 34.225.169.9...
