json - 去 Json 的 ASCII

Question

我对编程有点陌生，但我发现 python 没有我需要的速度，所以我转而去，我正在构建一个抓取器，我需要将一个看起来像是 ASCII 格式的字符串转换为 json，但我找不到关于如何在 go 中执行此操作的任何好的文档。

我需要转换的字符串看起来像这样:debug%22%3Afalse%2C%22pageOpts%22%3A%7B%22noBidIfUnsold%22%3Atrue%2C%22keywords%22%3A%7B%22no-sno-finn -object_type%22%3A%22private%22%2C%22no-sno-finn-car_make%22%3A%22796%22%2C%22aa-sch-publisher%22%3A%22finn%22%2C%22aa-sch -inventory_type%22%3A%22classified%22%2C%22aa-sch-country_code%22%3A%22no%22%2C%22no-sno-finn-section%22%3A%22car%22%2C%22no-sno -finn-ad_owner%22%3A%22false%22%2C%22no-sno-publishergroup%22%3A%22schibsted%22%2C%22aa-sch-supply_type%22%3A%22web_desktop%22%2C%22no-sno -finn-subsection%22%3A%22car_used%22%2C%22aa-sch-page_type%22%3A%22object%22%7D

提前致谢!

Answer 1

正如评论者所提到的，您的字符串是 URL 编码的，可以使用 url.QueryUnescape(...) 进行解码。 :

package main

import (
  "fmt"
  "net/url"
)

func main() {
  querystr := "debug%22%3Afalse%2C%22pageOpts%22%3A%7B%22noBidIfUnsold%22%3Atrue%2C%22keywords%22%3A%7B%22no-sno-finn-object_type%22%3A%22private%22%2C%22no-sno-finn-car_make%22%3A%22796%22%2C%22aa-sch-publisher%22%3A%22finn%22%2C%22aa-sch-inventory_type%22%3A%22classified%22%2C%22aa-sch-country_code%22%3A%22no%22%2C%22no-sno-finn-section%22%3A%22car%22%2C%22no-sno-finn-ad_owner%22%3A%22false%22%2C%22no-sno-publishergroup%22%3A%22schibsted%22%2C%22aa-sch-supply_type%22%3A%22web_desktop%22%2C%22no-sno-finn-subsection%22%3A%22car_used%22%2C%22aa-sch-page_type%22%3A%22object%22%7D"

  // Parse the URL encoded string.
  plainstr, err := url.QueryUnescape(querystr)
  if err != nil {
    panic(err)
  }
  fmt.Println(plainstr)
  // debug":false,"pageOpts":{"noBidIfUnsold":true,"keywords":{"no-sno-finn-object_type":"private","no-sno-finn-car_make":"796","aa-sch-publisher":"finn","aa-sch-inventory_type":"classified","aa-sch-country_code":"no","no-sno-finn-section":"car","no-sno-finn-ad_owner":"false","no-sno-publishergroup":"schibsted","aa-sch-supply_type":"web_desktop","no-sno-finn-subsection":"car_used","aa-sch-page_type":"object"}

}

您的示例字符串似乎不完整，但最终可以使用 json.Unmarshal(...) 将其解码为结构或映射。 .
