我正在尝试集成使用GTmetrix的某些网站的性能测试。使用API,我可以使用Microsoft中的SEO连接器工具运行测试并提取结果。然而,它使用的xml与较早版本的API,一些新的测试是不可用的。最新版本是2.0
xml的链接在这里:GTmetrix XMLforAPI0.1。
我试过使用httr和jsonlite库。但是,我不知道如何使用API进行身份验证,运行测试并提取结果。
API的文档可在API文档上获得。
library(httr)
library(jsonlite)
url <- "https://www.berkeley.edu" # URL to be tested
location <- 1 # testing Location
browser <- 3 # Browser to be used for testing
res <- GET("https://gtmetrix.com/api/gtmetrix-openapi-v2.0.json")
data <- fromJSON(rawToChar(res$content))发布于 2021-11-06 20:47:46
更新2021-11-08:
我创建了一个小型库,通过R与GTmetrix对话。这里有一些基本的健全检查,但很明显,这仍在进行中,而且还存在一些(潜在的关键)错误。不过,你可以随便看看。会喜欢一些反馈的。
# Install and load library.
devtools::install_github("RomanAbashin/rgtmx")
library(rgtmx)更新2021-11-12:它现在可以在CRAN上使用。:-)
# Install and load library.
install_packages("rgtmx")
library(rgtmx)开始测试(并获得结果)
# Minimal example #1.
# Returns the final report after checking test status roughly every 3 seconds.
result <- start_test("google.com", "[API_KEY]")这将启动一个测试,并等待生成报告,并以data.frame的形式返回结果。或者,您只需通过参数wait_for_completion = FALSE返回测试ID和其他元数据即可。
# Minimal example #2.
# Returns just the test ID and some meta data.
result <- start_test("google.com", "[API_KEY]", wait_for_completion = FALSE)其他可选参数:location、browser、report、retention、httpauth_username、httpauth_password、adblock、cookies、video、stop_onload、throttle、allow_url、block_url、dns、simulate_device、user_agent、browser_width、browser_height、d23、browser_rotate。
显示可用浏览器
show_available_browsers("[API_KEY]")显示可用位置
show_available_locations("[API_KEY]")获得特定测试
get_test("[TEST_ID]", "[API_KEY]")得到具体的报告
get_report("[REPORT_ID]", "[API_KEY]")做所有的测试
get_all_tests("[API_KEY]")获取帐户状态
get_account_status("[API_KEY]")原来的答案:
实际上,很简单:
0。设定测试参数。
# Your api key from the GTmetrix console.
api_key <- "[Key]"
# All attributes except URL are optional, and the availability
# of certain options may depend on the tier of your account.
# URL to test.
url <- "https://www.worldwildlife.org/"
# Testing location ID.
location_id <- 1
# Browser ID.
browser_id <- 31.开始测试
res_test_start <- httr::POST(
url = "https://gtmetrix.com/api/2.0/tests",
httr::authenticate(api_key, ""),
httr::content_type("application/vnd.api+json"),
body = jsonlite::toJSON(
list(
"data" = list(
"type" = "test",
"attributes" = list(
"url" = url,
# Optional attributes go here.
"location" = location_id,
"browser" = browser_id
)
)
),
auto_unbox = TRUE
),
encode = "raw"
)2.获取测试ID
test_id <- jsonlite::fromJSON(rawToChar(res_test_start$content))$data$id3.获取报告ID
# Wait a bit, as generating the report can take some time.
res_test_status <- httr::GET(
url = paste0("https://gtmetrix.com/api/2.0/tests/", test_id),
httr::authenticate(api_key, ""),
httr::content_type("application/vnd.api+json")
)
# If this returns the test ID, the report is not ready, yet.
report_id <- jsonlite::fromJSON(rawToChar(res_test_status$content))$data$id4.取得报告
res_report <- httr::GET(
url = paste0("https://gtmetrix.com/api/2.0/reports/", report_id),
httr::authenticate(api_key, ""),
httr::content_type("application/vnd.api+json")
)
# The report is a nested list with the results as you know them from GTmetrix.
report <- jsonlite::fromJSON(rawToChar(res_report$content))$data我有点想为此做点什么,因为似乎没有R库.
