我正在尝试访问一个 API，它检索一些数据并将其存储在数据框中。
以下代码应该是完全可重现的。
require("httr")
require("jsonlite")
require("tidyverse")
vouches2 <- data.frame()
reproducible_list <- c("0x00d18ca9782be1caef611017c2fbc1a39779a57c", "0x105645ffea02c7c8feaa1a32c100f1a30766d6a9")
for(i in reproducible_list){
theURL <- paste0("HTTPS://api.poh.dev/profiles/", i, "/vouches")
r <- GET(theURL)
message("Getting ", theURL)
s <- content(r, as = "text", encoding = "UTF-8")
message("DEBUG contntent(...) success")
df <- as.data.frame(fromJSON(s,flatten = TRUE, simplifyDataFrame=FALSE))
message(names(df))
message("as.data.frame success")
#
# df_filtered <- df %>%
# select(given.eth_address,given.status,given.display_name) %>%
# mutate(voucher = i) %>%
# mutate(voucher_name = data_filtered$display_name[data_filtered$id == i]) %>%
# filter(!is.na(voucher_name)) # remueve los que no estan en la lista de challengers frecuentes
message("DEBUG bind_rows")
vouches2 <- bind_rows(vouches2, df)
message("DEBUG bind_rows DONE")
Sys.sleep(0.5)
}
列表中的第一项 (0x00d18ca9782be1caef611017c2fbc1a39779a57c) 运行良好。问题是列表中的第二项（值 0x105645ffea02c7c8feaa1a32c100f1a30766d6a9）显示此错误：
Error in (function (..., row.names = NULL, check.rows = FALSE, check.names = TRUE, :
arguments imply differing number of rows: 0, 1
我认为发生这种情况的原因是第二个值有一组空的列（与 json 数据中的“给定”相关联）。

我想要一些关于如何面对这个问题的一般指导。我相信这与处理空行有关，但我不完全确定。
