Android - 奇怪的EscapeUtil.unescapeString崩溃

Question

从我们的应用程序服务器接收JSON字符串时遇到崩溃.我们认为,当条目具有"引号"时,会添加额外的转义.

在android中,我如何确定是否收到这样的字符串,以及如何从Android端修复它？

这是我们当前的响应字符串处理:

public String processResponseString(String responseString) {
    if (responseString.startsWith("\"")) {
        responseString = responseString.substring(1, responseString.length());
    }
    if (responseString.endsWith("\"")) {
        responseString = responseString.substring(0, responseString.length() - 1);
    }
    responseString = EscapeUtil.unescapeString(responseString);
    return responseString;
}

此外,崩溃后logcat不包含整个json字符串,因此我无法看到导致崩溃的实际字符串.

我试图复制你的字符串。我假设您想保留引号。我可以用这个简单的算法解决它，希望它对你有用：

    public static String process(String s){
       String sep = "\\\\";
       String[] arr = s.split(sep);
       StringBuilder sb = new StringBuilder();

       for(String str : arr){
          sb.append(str);
       }

       return sb.toString();
    }
