http Dart包示例已经过时，如何使用client.get()

Question

这里是http包给出的第二个例子：https://pub.dev/packages/http

var client = http.Client();
try {
  var uriResponse = await client.post('https://example.com/whatsit/create',
      body: {'name': 'doodle', 'color': 'blue'});
  print(await client.get(uriResponse.bodyFields['uri']));
} finally {
  client.close();
}

我收到错误：uriResponse.bodyFields['uri'] no such method.

我可以看到 class 响应中没有属性命名的 bodyFields：https://pub.dev/documentation/http/latest/http/Response-class.html

那么我应该如何使用client.get()？

我检查了函数 https://pub.dev/documentation/http/latest/http/get.html 的文档，然后我写了这个：

print(await client.get(uriResponse.request.url, {
      'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/85.0.4183.121 Safari/537.36',
}));

但这也失败并出现错误：

Class 'IOClient' has no instance method 'get' with matching arguments.
E/flutter (19613): Receiver: Instance of 'IOClient'
E/flutter (19613): Tried calling: get(Instance of '_SimpleUri', Instance of '_CompactLinkedHashSet<Map<String, String>>')
E/flutter (19613): Found: get(dynamic, {Map<String, String> headers}) => Future<Response>

Answer 1

如下所示编写您的 post 并单独打印回复。

final response = await client.post(
    '*endPoint url*',
    headers: *headers if you have any*,
    body: jsonEncode({'name': 'doodle', 'color': 'blue'}
    ));

print(json.decode((response.body)));

get 方法也遵循相同的结构。

Answer 2

String url = "url";
Response response = await client.get(url);
print('Response status: ${response.statusCode}');
print('Response body: ${json.decode((response.body))}');
