Flutter 身体在颤振中未使用map发送

服务器的响应显示了这一点

{“error”：1，“data”：{}，“message”：“请添加必填字段：email，password”}

如果没有“content-length”标题，该服务器似乎无法正确接受请求。这将使您的代码正常工作：

HttpClient client = new HttpClient();
    client.badCertificateCallback = ((X509Certificate cert, String host, int port) => true);

    String url ='https://dev.jobma.com:8090/v4/jobseeker/login';
    Map map = {
      "email":"hope@yopmail.com",
      "password":"123456"
    };
    print(map);
    HttpClientRequest request = await client.postUrl(Uri.parse(url));
    request.headers.set('content-type', 'application/json');
    request.add(utf8.encode(json.encode(map)));
    HttpClientResponse response = await request.close();
    String reply = await response.transform(utf8.decoder).join();
    print(reply);

HttpClient=newhttpclient（）；
client.badCertificateCallback=
（（X509证书证书证书，字符串主机，int端口）=>true）；
字符串url='0https://dev.jobma.com:8090/v4/jobseeker/login';
地图={
“电子邮件”：hope@yopmail.com",
“密码”：“123456”
};
印刷（地图）；
//在这里创造身体
List body=utf8.encode（json.encode（map））；
HttpClientRequest=wait client.postrl（Uri.parse（url））；
request.headers.set（'content-type'，'application/json'）；
//在此处设置内容长度标题
request.headers.set（'Content-Length'，body.Length.toString（））；
//将正文添加到请求中
请求.添加（正文）；
HttpClientResponse response=等待请求。关闭（）；
String reply=wait response.transform（utf8.decoder.join（）；
打印（答复）；

如果您可以使用dart pub中提供的软件包，这将非常容易

HttpClient client = new HttpClient();

client.badCertificateCallback =
  ((X509Certificate cert, String host, int port) => true);

String url = 'https://dev.jobma.com:8090/v4/jobseeker/login';
Map map = {
  "email": "hope@yopmail.com",
  "password": "123456"
};
print(map);

// Creating body here
List<int> body = utf8.encode(json.encode(map));

HttpClientRequest request = await client.postUrl(Uri.parse(url));
request.headers.set('content-type', 'application/json');

// Setting the content-length header here
request.headers.set('Content-Length', body.length.toString());

// Adding the body to the request
request.add(body);

HttpClientResponse response = await request.close();
String reply = await response.transform(utf8.decoder).join();
print(reply);

若你们能使用dart酒吧提供的软件包，那个就容易多了

HttpClient client = new HttpClient();

client.badCertificateCallback =
  ((X509Certificate cert, String host, int port) => true);

String url = 'https://dev.jobma.com:8090/v4/jobseeker/login';
Map map = {
  "email": "hope@yopmail.com",
  "password": "123456"
};
print(map);

// Creating body here
List<int> body = utf8.encode(json.encode(map));

HttpClientRequest request = await client.postUrl(Uri.parse(url));
request.headers.set('content-type', 'application/json');

// Setting the content-length header here
request.headers.set('Content-Length', body.length.toString());

// Adding the body to the request
request.add(body);

HttpClientResponse response = await request.close();
String reply = await response.transform(utf8.decoder).join();
print(reply);
