这是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();
}
我得到错误:uriResponse.bodyFields['uri'] no such method.
我可以看到响应类中没有名为 bodyFields 的属性:https ://pub.dev/documentation/http/latest/http/Response-class.html
那么我应该如何使用client.get()
呢?
我检查了函数https://pub.dev/documentation/http/latest/http/get.html的文档并写了这个:
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'
