Xamarin App调用HTTPS时崩溃 [英] Xamarin App crashes calling HTTPS
本文介绍了Xamarin App调用HTTPS时崩溃的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我创建了一个简单的Xamarin.Forms应用程序，以使用 https://jsonplaceholder.typicode.com/来检查HTTPS. a>.
但是应用程序使用HTTPS崩溃.
public RestService() {
client = new HttpClient();
client.MaxResponseContentBufferSize = 256000;
}
public async Task<List<Item>> RefreshDataAsync() {
string url = "http://jsonplaceholder.typicode.com/posts";
// Crash using this URL
//string url = "https://jsonplaceholder.typicode.com/posts";
var uri = new Uri(string.Format(url, string.Empty));
List<Item> Items = new List<Item>();
var content = await client.GetStringAsync(uri);
Items = JsonConvert.DeserializeObject<List<Item>>(content);
return Items;
}
}
网站或httpClient是否有问题，或者我做错了什么?
那是例外

解决方案
我找到了有关您的问题的帖子( https://forums.xamarin.com/discussion/10405/the-authentication-or-decryption-has-failed-in-the -web-request )
在注释中，您会发现有人建议使用软件包 modernhttpclient
使用此软件包的方式: HttpClient client = new HttpClient(new NativeMessageHandler());
NativeMessagehandler将解决证书问题(由于u使用https给出了身份验证错误，因此可以解决此问题)
对于其余部分，您可以像使用该客户端一样使用该客户端.
祝你好运
I created a simple Xamarin.Forms App to check HTTPS using https://jsonplaceholder.typicode.com/.
But the App crashes using HTTPS.
public RestService() {
client = new HttpClient();
client.MaxResponseContentBufferSize = 256000;
}
public async Task<List<Item>> RefreshDataAsync() {
string url = "http://jsonplaceholder.typicode.com/posts";
// Crash using this URL
//string url = "https://jsonplaceholder.typicode.com/posts";
var uri = new Uri(string.Format(url, string.Empty));
List<Item> Items = new List<Item>();
var content = await client.GetStringAsync(uri);
Items = JsonConvert.DeserializeObject<List<Item>>(content);
return Items;
}
}
Is it a problem with the website or httpClient or do I do somethin wrong ?
Thats the Exception

解决方案
I found a post about your issue (https://forums.xamarin.com/discussion/10405/the-authentication-or-decryption-has-failed-in-the-web-request)
Here in the comments you will find someone suggesting to use the package modernhttpclient
The way to work with this package: HttpClient client = new HttpClient(new NativeMessageHandler());
The NativeMessagehandler will solve the certifcations issue ( since u using https it gave a authentication error, this will solve it)
For the rest you can use the client as you were already using it.
Good luck
