可使用状态代码提供错误信息。

mathworks.com 网站发送一条 PUT 消息。

uri = matlab.net.URI('https://www.mathworks.com');
header = matlab.net.http.field.ContentTypeField('text/plain');
req = matlab.net.http.RequestMessage('put',header,'Data');
resp = send(req, uri);

此网站不允许使用 PUT 方法。将显示一条对用户友好的消息。

sc = resp.StatusCode;
if sc ~= matlab.net.http.StatusCode.OK
    disp([getReasonPhrase(getClass(sc)),': ',getReasonPhrase(sc)])
    disp(resp.StatusLine.ReasonPhrase)
end
Client Error: Method Not Allowed
Method Not Allowed

StatusCode 方法 - charstringgetReasonPhrasegetClass - 提供有关代码及其含义的信息。可根据您的要求选择一种方法。

假定您的响应消息中包含状态代码 307。要运行此示例,请创建以下代码。

sc = matlab.net.http.StatusCode(307);

使用 chargetReasonPhrase 方法返回说明状态代码含义的文本。getReasonPhrase 方法创建可在消息中使用的短语。

txt = char(sc)
txt = 
'TemporaryRedirect'
msg = getReasonPhrase(sc)
msg = 
'Temporary Redirect'

使用 string 方法以字符串形式返回状态代码的整数值。

value = string(sc)
value = 
"307"

如果您的代码基于状态类来处理状态代码,请使用 getClass 方法。

class = getClass(sc)
class = 
  StatusClass enumeration
