我正在通过使用 dio 传递表单数据并获得响应，但我无法将数据存储到对象。请帮我 它在我打印 response.data 时给出响应，但我不知道如何存储对对象的响应。
class MainActivityGrid extends StatefulWidget {
@override
_MainActivityGridState createState() => _MainActivityGridState();
}
class _MainActivityGridState extends State<MainActivityGrid> {
// List<ImageModel>images= [];
@override
Widget build(BuildContext context) {
return MaterialApp(
home: new Scaffold(
appBar: AppBar(
title: new Text("IPTV"),
),
body: new Center(
child: new RaisedButton(
child: new Text("Button"), onPressed: fetchImage),
),
),
);
}
Future<String> fetchImage() async {
String url = "http://xxxxxx:xxx/onnet_api/mediaList.php";
Response response;
Dio dio = new Dio();
FormData formData = new FormData.from(
{"publisherid": 102, "tag": "media", "subtag": "list"});
// counter ++;
response = await dio.post(url, data: formData);
// dio.interceptors.add(LogInterceptor(responseBody: fa));
//int status = response.data["status"]["data"];
//Map responseBody = response.data;
//loginResponse = new LoginResponse.fromJson(json.decode(response.data));
print(response.data["data"][0]);
//ImageModel imageModel = new ImageModel.fromJson(json.decode(response.data[]));
//print('response media: $status');
/* setState(() {
//images.add(imageModel);
});*/
}
}
我的 API 的 JSON 响应如下所示:请尝试帮助我解决这个问题。

最佳答案
无需为Dio 使用Json Decode。您可以执行如下操作:
Response responseval=await dio.post(url,options: Options(headers: headers));
var name=responseval.data['username'];
var id=responseeval.data['id'];
关于android - 如何使用dio在 flutter 中存储对对象的响应，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/54703549/

总的来说，我对ruby还比较陌生，我正在为我正在创建的对象编写一些rspec测试用例。许多测试用例都非常基础，我只是想确保正确填充和返回值。我想知道是否有办法使用循环结构来执行此操作。不必为我要测试的每个方法都设置一个assertEquals。例如:describeitem,"TestingtheItem"doit"willhaveanullvaluetostart"doitem=Item.new#HereIcoulddotheitem.name.shouldbe_nil#thenIcoulddoitem.category.shouldbe_nilendend但我想要一些方法来使用
我有一个Ruby程序，它使用rubyzip压缩XML文件的目录树。gem。我的问题是文件开始变得很重，我想提高压缩级别，因为压缩时间不是问题。我在rubyzipdocumentation中找不到一种为创建的ZIP文件指定压缩级别的方法。有人知道如何更改此设置吗？是否有另一个允许指定压缩级别的Ruby库？ 最佳答案 这是我通过查看rubyzip内部创建的代码。level=Zlib::BEST_COMPRESSIONZip::ZipOutputStream.open(zip_file)do|zip|Dir.glob("**/*")d

很好奇，就使用rubyonrails自动化单元测试而言，你们正在做什么？您是否创建了一个脚本来在cron中运行rake作业并将结果邮寄给您？git中的预提交Hook？只是手动调用？我完全理解测试，但想知道在错误发生之前捕获错误的最佳实践是什么。让我们理所当然地认为测试本身是完美无缺的，并且可以正常工作。下一步是什么以确保他们在正确的时间将可能有害的结果传达给您？ 最佳答案 不确定您到底想听什么，但是有几个级别的自动代码库控制:在处理某项功能时，您可以使用类似autotest的内容获得关于哪些有效，哪些无效的即时反馈。要确保您的提
假设我做了一个模块如下:m=Module.newdoclassCendend三个问题:除了对m的引用之外，还有什么方法可以访问C和m中的其他内容？我可以在创建匿名模块后为其命名吗(就像我输入“module...”一样)？如何在使用完匿名模块后将其删除，使其定义的常量不再存在？ 最佳答案 三个答案:是的，使用ObjectSpace.此代码使c引用你的类(class)C不引用m:c=nilObjectSpace.each_object{|obj|c=objif(Class===objandobj.name=~/::C$/)}当然这取决于
我正在尝试使用ruby和Savon来使用网络服务。测试服务为http://www.webservicex.net/WS/WSDetails.aspx?WSID=9&CATID=2require'rubygems'require'savon'client=Savon::Client.new"http://www.webservicex.net/stockquote.asmx?WSDL"client.get_quotedo|soap|soap.body={:symbol=>"AAPL"}end返回SOAP异常。检查soap信封，在我看来soap请求没有正确的命名空间。任何人都可以建议我
关闭。这个问题是opinion-based.它目前不接受答案。想要改进这个问题？更新问题，以便editingthispost可以用事实和引用来回答它.关闭4年前。Improvethisquestion我想在固定时间创建一系列低音和高音调的哔哔声。例如:在150毫秒时发出高音调的蜂鸣声在151毫秒时发出低音调的蜂鸣声200毫秒时发出低音调的蜂鸣声250毫秒的高音调蜂鸣声有没有办法在Ruby或Python中做到这一点？我真的不在乎输出编码是什么(.wav、.mp3、.ogg等等)，但我确实想创建一个输出文件。
给定这段代码defcreate@upgrades=User.update_all(["role=?","upgraded"],:id=>params[:upgrade])redirect_toadmin_upgrades_path,:notice=>"Successfullyupgradeduser."end我如何在该操作中实际验证它们是否已保存或未重定向到适当的页面和消息？ 最佳答案 在Rails3中，update_all不返回任何有意义的信息，除了已更新的记录数(这可能取决于您的DBMS是否返回该信息)。http://ar.ru
在控制台中反复尝试之后，我想到了这种方法，可以按发生日期对类似activerecord的(Mongoid)对象进行分组。我不确定这是完成此任务的最佳方法，但它确实有效。有没有人有更好的建议，或者这是一个很好的方法？#eventsisanarrayofactiverecord-likeobjectsthatincludeatimeattributeevents.map{|event|#converteventsarrayintoanarrayofhasheswiththedayofthemonthandtheevent{:number=>event.time.day,:event=>ev
