上一篇文章中我们谈到了阿里云天气接口的使用，但是，在这个接口返回的数据中，有一个图标问题是需要我们注意的。
如图所示：
阿里云接口返回的天气图标是一个状态值，拿到之后是没法直接使用的，所以，我们需要将img的状态值替换成
我们所需要的url，然后在传送到客户端。
处理这个问题的思路是很多的，下面我就说一下自己的思路：
//step1 调用阿里云天气接口返回数据
String host = "http://jisutqybmf.market.alicloudapi.com";
String path = "/weather/query";
String method = "GET";
String appcode = "efef9016ff904a92baaae4be65a*****";
Map<String, String> headers = new HashMap<String, String>();
//最后在header中的格式(中间是英文空格)为Authorization:APPCODE 83359fd73fe94948385f570e3c139105
headers.put("Authorization", "APPCODE " + appcode);
Map<String, String> querys = new HashMap<String, String>();
querys.put("city", "北京");
HttpResponse response = WeatherForexUtils.doGet(host, path, method, headers, querys);
//step2 weather查询出来的结果 转换成字符串
String weather = EntityUtils.toString(response.getEntity());
//step3 将weather中所有的 ":" 替换成@
String weatherReplace = weather.replace("\":\"", "@");
//step4 自己定义的json字符串 这个json我是存在了数据库中 文章底部我会给大家给出自己定义的json数组供参考
String weatherIcon = getMessage(SERVICE);
//step5 将字符串转换为json数组 然后遍历 替换目标str中的img@1 成自己需要的newStr,注意：需要倒序遍历
JSONArray json = JSONArray.parseArray(weatherIcon);
if(json.size()>0) {
for (int i = json.size()-1; i >=0; i--) {
JSONObject job = json.getJSONObject(i);
if(weatherReplace.indexOf(job.get("imgId").toString())!=-1){
weatherReplace = weatherReplace.replace(job.get("imgId").toString(),job.get("imgPath").toString());
}
}
}
//step6 将newStr中的 @ 替换为 ":" 然后就大功告成 此时newStr就是我们需要的数据了
String string=weatherReplace.replace("@", "\":\"");如图所示，就是转换后的数据结构：
完整的代码逻辑如下，可以直接使用
String host = "http://jisutqybmf.market.alicloudapi.com";
String path = "/weather/query";
String method = "GET";
String appcode = "efef9016ff904a92baaae4be65a******";
Map<String, String> headers = new HashMap<String, String>();
//最后在header中的格式(中间是英文空格)为Authorization:APPCODE 83359fd73fe94948385f570e3c139105
headers.put("Authorization", "APPCODE " + appcode);
Map<String, String> querys = new HashMap<String, String>();
querys.put("city", "北京");
try {
HttpResponse response = WeatherForexUtils.doGet(host, path, method, headers, querys);
/**
* 处理天气图片的逻辑
*/
// 1 weather查询出来的结果 转换成字符串
String weather = EntityUtils.toString(response.getEntity());
// 2 将weather中所有的 ":" 替换成 @
String weatherReplace = weather.replace("\":\"", "@");
// 3 查询出自己定义的json字符串
String weatherIcon = getMessage(SERVICE);
// 4 将字符串转换为json数组 然后遍历 替换目标str中的img@1 成自己需要的newStr
JSONArray json = JSONArray.parseArray(weatherIcon);
if(json.size()>0) {
for (int i = json.size()-1; i >=0; i--) {
JSONObject job = json.getJSONObject(i);
if(weatherReplace.indexOf(job.get("imgId").toString())!=-1){
weatherReplace = weatherReplace.replace(job.get("imgId").toString(),job.get("imgPath").toString());
}
}
}
// 5 将newStr中的 @ 替换为 : 后set
String string=weatherReplace.replace("@", "\":\"");
} catch (Exception e) {
e.printStackTrace();
}
这是自己定义的json数组，图片需要自己shangchu供参考使用。注：图片在阿里云官网有，可以直接打包下载
