AHK 通过公开的天气API获取json数据并读取

我觉得获取天气这个东西没有太大必要,但是找了半天论坛上也没有能用的了,现在.

所以,我找到了相关的api和函数,可以顺利读取天气数据.

用两个函数即可,这两个函数是在github中找到的http://howiefh.github.io

不过他用的哪个天气url api好像已经不能用了,我换了一个可以直接用的.

然后效果如图:

result := UrlDownloadToVar("http://t.weather.sojson.com/api/weather/city/101270101","utf-8") ; 101270101为天气预报城市id  api接口https://www.sojson.com/api/weather.html

;msgbox %result% ;检查是否获取

city := json(result, "cityInfo.city")
tmp := json(result, "data.wendu")
quality := json(result, "data.quality")
htype := json(Result, "data.forecast[0].type") ;读取数组中的值
high0 := json(Result, "data.forecast[0].high")
low0 := json(Result, "data.forecast[0].low")

msgbox, %city%: %tmp%℃ %htype% `n 明日 %quality%  %high0% %low0%
Return

json(ByRef js, s, v = "") 
{
	j = %js%
	Loop, Parse, s, .
	{
		p = 2
		RegExMatch(A_LoopField, "([+\-]?)([^[]+)((?:\[\d+\])*)", q)
		Loop {
			If (!p := RegExMatch(j, "(?<!\\)(""|')([^\1]+?)(?<!\\)(?-1)\s*:\s*((\{(?:[^{}]++|(?-1))*\})|(\[(?:[^[\]]++|(?-1))*\])|"
				. "(?<!\\)(""|')[^\7]*?(?<!\\)(?-1)|[+\-]?\d+(?:\.\d*)?|true|false|null?)\s*(?:,|$|\})", x, p))
				Return
			Else If (x2 == q2 or q2 == "*") {
				j = %x3%
				z += p + StrLen(x2) - 2
				If (q3 != "" and InStr(j, "[") == 1) {
					StringTrimRight, q3, q3, 1
					Loop, Parse, q3, ], [
					{
						z += 1 + RegExMatch(SubStr(j, 2, -1), "^(?:\s*((\[(?:[^[\]]++|(?-1))*\])|(\{(?:[^{\}]++|(?-1))*\})|[^,]*?)\s*(?:,|$)){" . SubStr(A_LoopField, 1) + 1 . "}", x)
						j = %x1%
					}
				}
								
								
				Break
			}
			Else p += StrLen(x)
		}
	}
	If v !=
	{
		vs = "
		If (RegExMatch(v, "^\s*(?:""|')*\s*([+\-]?\d+(?:\.\d*)?|true|false|null?)\s*(?:""|')*\s*$", vx)
			and (vx1 + 0 or vx1 == 0 or vx1 == "true" or vx1 == "false" or vx1 == "null" or vx1 == "nul"))
			vs := "", v := vx1
		StringReplace, v, v, ", \", All
		js := SubStr(js, 1, z := RegExMatch(js, ":\s*", zx, z) + StrLen(zx) - 1) . vs . v . vs . SubStr(js, z + StrLen(x3) + 1)
	}
	Return, j == "false" ? 0 : j == "true" ? 1 : j == "null" or j == "nul"
		? "" : SubStr(j, 1, 1) == """" ? SubStr(j, 2, -1) : j
