一直在尝试使用 go 解析此 json 文件以获取给定城市的最低和最高温度。{ "data": { "current_condition": [ { "cloudcover": "25", "humidity": "56", "observation_time": "01:33 PM", "precipMM": "0.0", "pressure": "1016", "temp_C": "20", "temp_F": "68", "visibility": "10", "weatherCode": "116", "weatherDesc": [ { "value": "Partly Cloudy" } ], "weatherIconUrl": [ { "value": "http://cdn.worldweatheronline.net/images/wsymbols01_png_64/wsymbol_0002_sunny_intervals.png" } ], "winddir16Point": "SSW", "winddirDegree": "210", "windspeedKmph": "7", "windspeedMiles": "4" } ], "request": [ { "query": "London, United Kingdom", "type": "City" } ], "weather": [ { "date": "2014-09-07", "precipMM": "0.0", "tempMaxC": "23", "tempMaxF": "74", "tempMinC": "10", "tempMinF": "49", "weatherCode": "119", "weatherDesc": [ { "value": "Cloudy" } ] }} 已成功使用结构和解码 json 字符串。现在我想尝试使用地图,例如map[string]interface{}如果 u 是类型map[string]interface{}并且 json 被解析为 u,则u["data"].(map[string]interface{})["weather"]给出值而u["data"].(map[string]interface{})["weather"].(map[string]interface{})["tempMinC"],给了我一个panic: interface conversion: interface is []interface {}, not map[string]interface {}有人可以解释发生了什么吗?
