项目有设计这个板块，网上搜了一下发现对应博客已经很老了，官方文档也没有匹配对应介绍，

我这里设计的是通过用户IP获取当前所在地区，再通过所在地区获取当地天气，其中的参数什么的详情请见官方文档，我这里只用了城市，天气，温度，风向的参数。

 created() {
    const that = this;
    const token = getToken();
    if (this.userIp === "") {
      getIp(token).then((res) => {
        this.userIp = res.ip;
        console.log(this.userIp);
        const userInput = this.userIp;
        const apiKey = "和风控制台有自己的api";
        const apiURL = `https://geoapi.qweather.com/v2/city/lookup?location=${userInput}&key=${apiKey}`;

        console.log("apiURL", apiURL);
        fetch(apiURL)
          .then((response) => {
            if (!response.ok) {
              throw new Error("Network response was not ok");
            }
            return response.json();
          })
          .then((data) => {
            if (data.code === "200") {
              this.location = [...data.location];
              if (this.location[0].id !== "") {
                const Id = this.location[0].id;
                console.log("this.location", Id);
                const apiURL2 = `https://devapi.qweather.com/v7/weather/now?location=${Id}&key=${apiKey}`;
                console.log("apiURL2", apiURL2);
                fetch(apiURL2)
                  .then((response) => {
                    if (!response.ok) {
                      throw new Error("Network response was not ok");
                    }
                    return response.json();
                  })
                  .then((data) => {
                    console.log("data", data);
                    if (data.code === "200") {
                      that.weather = data.now;
                      console.log(that.weather);
                    } else if (data.code === "404") {
                      this.$message("当前地区天气数据暂无");
                    } else {
                      // throw new Error("API returned error code: " + data.code);
                    }
                  })
                  .catch((error) => {
                    console.error("获取城市天气时发生错误:", error);
                  });
              }
            } else if (data.code === "404") {
              this.$message("当前地区天气数据暂无");
            } else {
              // throw new Error("API returned error code: " + data.code);
            }
          })
          .catch((error) => {
            console.error("获取城市ID时发生错误:", error);
          });
        // setTimeout(() => {

        // }, 200);
      });
    }
  },

这里因为和风天气的链接原因，所以我选择使用fetch，但是还有一个很重要的点就是return response.json();　这一步代码
