android okhttp+Retrofit 发送带有/ ^等特殊字符返回400

 步骤一：

Observable getMsg(
        @Query("content") String content,      
);

Observable getMsg(
        @Query(value = "content", encoded = true) String content,      
);

步骤二：

对content进行手动编码:

URLEncoded(content);

public static String URLEncoded(String paramString) {
        if (TextUtils.isEmpty(paramString)) {
            return "";
        }
        try {
            String str = new String(paramString.getBytes(), "UTF-8");
            str = URLEncoder.encode(str, "UTF-8");
            return str;
        } catch (Exception e) {
            e.printStackTrace();
            return "";
        }
    }
