获取 http 上的颤振参数

Question

如何在 GET 函数上放置一个参数， 我在 dart 或 flutter 的文档中没有找到任何关于此的内容

String url = 'xxxxxx';

Future<String> makeRequest() async {

Map params = {
  "anunciante_name"
  "anunciante_pass"
  "anunciante_email"
};

var _body = jsonDecode(params);

var response = await http
.get(Uri.encodeFull(url), headers: {"Content-type": "application/json", "key": "xxxxx", "token": "xxxxx"},);

print(response.body);

Answer 1

根据documentation for the get method of the http对象，

Future<Response> get (dynamic url, {Map<String, String> headers})

第二个参数是headers。您可以将您的每个参数作为值传递给它，就像您传递 key、token 和 Content-Type 一样。

Map<String, String> reqHeaders = {
    "Content-type": "application/json", 
    "key": "xxxxx", 
    "token": "xxxxx", 
    "anunciante_name":name,
    "anunciante_pass":password,
    "anunciante_email":email
};

var response = await http.get(Uri.encodeFull(url), {headers: reqHeaders});
