如何在Dart中将数据发布到https服务器？ [英] How to post data to https server in dart?
问题描述
所以我当时正在开发一个应用程序，所以遇到了一个问题。
我需要将JSON数据发布到https服务器。由于该应用程序目前正在开发中，因此我们正在使用自签名证书。
So i was building an application in flutter and I came across a problem. I need to post JSON data to a https server. Since the application is currently under development so we are using Self-Signed Certificate.
如何用飞镖语言实现？
How can I achieve this in dart language?
下面是我用来通过 http 向Web服务器发出单个发布请求的代码，但是每当我替换 http 与 https （自签名）时出现错误：
HandshakeException：客户端中的握手错误（操作系统错误：
CERTIFICATE_VERIFY_FAILED：自签名证书（handshake.cc:355））
Below is the code which I use to make single post request to the web server over http, but whenever I replace the http with https(Self Signed) I get an error:
HandshakeException: Handshake error in client (OS Error:
CERTIFICATE_VERIFY_FAILED: self signed certificate(handshake.cc:355))
var url = 'http://192.168.1.40/registration.php'; //or https
var data = {"email":"yyyy@xx.com","name":"xyz"};
http.post(url, body:data)
.then((response) {
print("Response status: ${response.statusCode}");
print("Response body: ${response.body}");
}).catchError((error) => print(error.toString()));
我对Flutter和Dart很陌生，请帮帮我。
I am pretty new to Flutter and Dart please help me out. Suggestions will be welcomed.
推荐答案
http.post 是方便的包装在幕后创建了一个IOClient。您可以将自己的io HttpClient传递给它，这具有禁用证书检查的方法，因此您只需要像这样自己构造它们即可...
http.post is a convenience wrapper which creates a IOClient under the hood. You can pass your own io HttpClient to this, and that has a way to disable the certificate checks, so you just have to construct them yourself like this...
bool trustSelfSigned = true;
HttpClient httpClient = new HttpClient()
..badCertificateCallback =
((X509Certificate cert, String host, int port) => trustSelfSigned);
IOClient ioClient = new IOClient(httpClient);
ioClient.post(url, body:data);
// don't forget to call ioClient.close() when done
// note, this also closes the underlying HttpClient
bool trustSelfSigned 控制是否获得默认行为或允许不良证书。
the bool trustSelfSigned controls whether you get the default behaviour or allows bad certificates.
