如何验证接口响应json字段值不为空

Answer 1

    // 获取验证字段不为空
    private String checkDataNotNull(List<String> lines, String key, String value) {
        String content = lines.toString();
        String value1 = value;// 存放一个value，因为后面回去value进行编辑
        if (key == null || key.isEmpty() || lines.isEmpty()) {
            return value1;
        }
        if (key.equalsIgnoreCase("notnull")) {
            value = value.replace("，", ",");// 替换掉中文逗号
            if (value.indexOf(",") == -1) {// 如果不存在逗号，则直接进入验证
                if (!content.contains(value1)) {
                    return author;
                }
                for (int k = 0; k < lines.size(); k++) {
                    String line = lines.get(k);
                    if (line.contains(key + ":")) {
                        String lineValue = deleteCharFromString(key + ":", line);
                        if (lineValue == null || lineValue.isEmpty()) {
                            return author;
                        }
                    }
                }
                return value1;

            } else {// 如果包含逗号，先将中文逗号转化为英文都好
                List<String> list = new ArrayList<>();// 用list存放获取到的value中的值
                for (int i = 0; i < 10; i++) {// for循环获取验证文本
                    if (value.indexOf(",") == -1) {// 如果已经到头，则直接赋值并添加list，跳出循环
                        String key1 = value;
                        list.add(key1);
                        break;
                    }
                    String key1 = value.substring(0, value.indexOf(","));// 截取字符串
                    list.add(key1);// 添加list
                    value = deleteCharFromString(key1 + ",", value);// 删除截取到的字符串
                }
                List<String> results = new ArrayList<String>();
                for (int i = 0; i < list.size(); i++) {
                    String keys = list.get(i);
                    for (int k = 0; k < lines.size(); k++) {
                        String line = lines.get(k);
                        if (line.contains(key + ":")) {
                            String lineValue = deleteCharFromString(key + ":", line);
                            if (lineValue == null || lineValue.isEmpty()) {
                                results.add(author);
                                break;
                            }
                        }
                    }
                    results.add(keys);
                }
                StringBuffer text = new StringBuffer();
                for (int i = 0; i < results.size(); i++) {
                    if (i == results.size() - 1) {
                        text.append(results.get(i));
                        continue;
                    }
                    text.append(results.get(i) + ",");
                }
                String texts = text.toString();
                // output(texts, value1);
                return texts;// 返回值
            }
        } else {
            return author;
        }
