java - URL 编码对我的字符串进行两次编码

Question

我有一个 Json 字符串要编码

String strMappingList = [{"Id": "67","AccessType": "2"},{"Id": "1111","AccessType": "2"},{"Id": "1166","AccessType": "2"}]

当我进行 url 编码时，它对 strMappingList 进行了两次编码

try {
    String str = URLEncoder.encode(strMappingList, "utf-8");
} catch (UnsupportedEncodingException e) {
    e.printStackTrace();
}

Answer 1

Try the code you take in strings file

如果您从服务器得到的响应没有在 string.xml 中使用，您可以直接使用

在 string.xml 中

  <string name="urls">[{"Id": "67","AccessType": "2"},{"Id": "1111","AccessType": "2"},{"Id": "1166","AccessType": "2"}]</string>

Code

String strMappingList = getResources().getString(R.string.urls);

try {
    String str = URLEncoder.encode(strMappingList, "UTF-8");
    System.out.println("Strings"+str);
} catch (UnsupportedEncodingException e) {
    e.printStackTrace();
}

Output Single time
