我正在使用PayPal PHP API设置订阅/定期付款流程。到目前为止，除了一件事-Webhooks之外，一切似乎都可以在沙箱中正常工作。即使Webhook事件显示为在线“发送”，我似乎也从未收到过它们。
我已经检查了webhook事件，并且其中的webhook URL（“传输”->“ webhook_url”）是正确的。如果我在浏览器中访问该URL，则在代码中设置的记录器将正确记录该URL。但是，当贝宝（PayPal）表示已发送Webhook时，我在日志中看不到任何内容（同样，即使它说它已在开发人员控制台中成功发送了Webhook）。
以下是PayPal所说的已发送的Webhook事件之一：
library(shiny)
library(tidyverse)
ui <- fluidPage(
mainPanel(
DT::dataTableOutput("flag"),
actionButton("exclude", "Exclude")
)
)
server <- function(input, output) {
df <- data.frame(id = 1:10, fu_score = 1:10,
stringsAsFactors = FALSE)
if (file.exists("data/prev_exclude.Rda")) {
load("data/prev_exclude.Rda")
} else {
prev_exclude <- data.frame(id = 0, fu_score = 0, stringsAsFactors = FALSE)
save(prev_exclude, file = "data/prev_exclude.Rda")
}
df_flag <- reactive({
df %>%
anti_join(., prev_exclude, by = c("id", "fu_score"))
})
output$flag <- DT::renderDataTable({
DT::datatable(df_flag(), options = list(paging = FALSE))
})
selected_prev <- eventReactive(input$flag_rows_selected, {
data.frame(id = df_flag()$id[c(input$flag_rows_selected)],
fu_score = df_flag()$fu_score[c(input$flag_rows_selected)])
})
observeEvent(input$exclude, {
prev_exclude <- isolate(bind_rows(selected_prev(), prev_exclude))
save(prev_exclude, file="data/prev_exclude.Rda")
load("data/prev_exclude.Rda")
})
}
# Run the application
shinyApp(ui = ui, server = server)
以及实际的Webhook脚本上的前几行代码（尽管我猜这无关紧要，因为我从一开始就进行日志记录，因此它至少应该记录某事当PayPal发送Webhook时）：
