如何獲取全部漢字及漢字的詳細信息？

剛剛扒了一通漢字完整的數據字典，mark作下記錄。

所有漢字集合

我們匹配中文字符時，經常使用Unicode字符"[^\u4e00-\u9fa5]"正則表達式來校驗。

詳細的漢字字符集列表可參考：

具體的漢字對應的字符，可查詢漢字字符集編碼查詢網站

基本漢字中從4e00到9fa5，十六進制轉化為十進制後，可知共有20902個漢字。

漢字的集合，是開源的，可以直接從網上獲取。

• 百度文庫-中國漢字大全
• Github-HanziToPinyin
• CSDN-中國所有漢字-簡體

從以上鏈接中，下載漢字集合

獲取漢字信息

漢字的詳細信息，包括拼音/筆畫數/部首/五筆輸入/筆順編號/註解

網上有相應的新華字典Api接口，這裏選的是聚合平臺-新華字典

通過他的C#源碼,我們可以獲取到漢字字典的詳細信息

詳細數據請點擊 下載

PS:

• 部首和五筆可能為空，部首返回的數據為："難檢字"。
• 筆順編號可通過返回的簡解中得到。筆順編號，即指每個筆畫對應的號碼，這個非常有用！

聚合接口-漢字

獲取漢字：

 1         public static HanziDetail FindHanzi(string hanzi)
 2         {
 3             //1.根據漢字查詢字典
 

 4             string url1 = "http://v.juhe.cn/xhzd/query";
 5 
 6             var parameters1 = new Dictionary<string, string>();
 7 
 8             parameters1.Add("word", hanzi); //填寫需要查詢的漢字，UTF8 urlencode編碼
 9             parameters1.Add("key", "XXXXXX");//你申請的key
10             parameters1.Add("
 
dtype", ""); //返回數據的格式,xml或json，默認json
11 
12             string result2 = SendPost(url1, parameters1, "get");
13 
14             var hanziRequestResponse = JsonConvert.DeserializeObject<HanziRequestResponse>(result2);
15 
16             //HanziDetail hanziDetail = null;
17             //if (hanziRequestResponse.ErrorCode == "0" && hanziRequestResponse.Result != null)
18             //{
19             //    hanziDetail = hanziRequestResponse.Result;
20             //}
21 
22             return hanziRequestResponse.Result;
23         }
24     }
