Flutter开发之——网络请求-手动json数据解析，终局之战

• 第三层(data/datas)：apkLink(String)，audit(int)，author(String)，canEdit(bool)，chapterId(int)，chapterName(String)，collect(bool)，courseId(int)，desc(String)，descMd(String)，envelopePic(String)，fresh(bool)，host(String)，id(int)，link(String)，niceDate(String)，niceShareDate(String)，origin(String)，prefix(String)，projectLink(String)，publishTime(int),realSuperChapterId(int),selfVisible(int)，shareDate(int)，shareUser(String)，superChapterId(int)，superChapterName(String)，tags(数据集合类),title(String)，type(int)，userId(int)，visible(int),zan(int)

• 第4层(data/datas/tags)

3.2 将String类型转换为Json类型(Map)

调用函数(String类型—>Json)

var jsonDecode = json.decode(responseBody);

3.3 Json类型转换为数据类(Article-第一层)

数据类(data设置为Object)

class Article {

int errorCode;

String errorMsg;

Object data;

Article(this.errorCode, this.errorMsg, this.data);

Article.formJson(Map json) {

Article(

errorCode= json[‘errorCode’],

errorMsg = json[‘errorMsg’],

data = json[‘data’]

);

}

}

转换后

3.4 将Json彻底转换为数据类

数据类

class Article {

int errorCode;

String errorMsg;

ArticleData data;

Article(this.errorCode, this.errorMsg, this.data);

Article.formJson(Map json) {

Article(

errorCode= json[‘errorCode’],

errorMsg = json[‘errorMsg’],

data = ArticleData.fromJson(json[‘data’])

);

}

}

class ArticleData {

int curPage;

int offset;

bool over;

int pageCount;

int size;

int total;

List datas;

ArticleData(this.curPage, this.offset, this.over, this.pageCount, this.size,

this.total, this.datas);

ArticleData.fromJson(Map json) {

var personList = List();

for (Map map in json[‘datas’]) {

personList.add(Person.fromJson(map));

}

ArticleData(

curPage = json[‘curPage’],

offset = json[‘curPage’],

over = json[‘over’],

pageCount = json[‘pageCount’],

size = json[‘size’],

total = json[‘total’],

datas = personList);

}

}

}

}

class Tag {

String name;

String url;

Tag.fromJson(Map json) {

Tag(name = json[‘name’], url = json[‘url’]);

}

}
