63 | \class QNetworkReply |
64 | \since 4.4 |
65 | \brief The QNetworkReply class contains the data and headers for a request |
66 | sent with QNetworkAccessManager. |
67 | |
68 | \reentrant |
69 | \ingroup network |
70 | \inmodule QtNetwork |
71 | |
72 | The QNetworkReply class contains the data and meta data related to |
73 | a request posted with QNetworkAccessManager. Like QNetworkRequest, |
74 | it contains a URL and headers (both in parsed and raw form), some |
75 | information about the reply's state and the contents of the reply |
76 | itself. |
77 | |
78 | QNetworkReply is a sequential-access QIODevice, which means that |
79 | once data is read from the object, it no longer kept by the |
80 | device. It is therefore the application's responsibility to keep |
81 | this data if it needs to. Whenever more data is received from the |
82 | network and processed, the readyRead() signal is emitted. |
83 | |
84 | The downloadProgress() signal is also emitted when data is |
85 | received, but the number of bytes contained in it may not |
86 | represent the actual bytes received, if any transformation is done |
87 | to the contents (for example, decompressing and removing the |
88 | protocol overhead). |
89 | |
90 | Even though QNetworkReply is a QIODevice connected to the contents |
91 | of the reply, it also emits the uploadProgress() signal, which |
92 | indicates the progress of the upload for operations that have such |
93 | content. |
94 | |
95 | \note Do not delete the object in the slot connected to the |
96 | errorOccurred() or finished() signal. Use deleteLater(). |

102 | \enum QNetworkReply::NetworkError |
103 | |
104 | Indicates all possible error conditions found during the |
105 | processing of the request. |
106 | |
107 | \value NoError no error condition. |
108 | \note When the HTTP protocol returns a redirect no error will be |
109 | reported. You can check if there is a redirect with the |
110 | QNetworkRequest::RedirectionTargetAttribute attribute. |
111 | |
112 | \value ConnectionRefusedError the remote server refused the |
113 | connection (the server is not accepting requests) |
114 | |
115 | \value RemoteHostClosedError the remote server closed the |
116 | connection prematurely, before the entire reply was received and |
117 | processed |
118 | |
119 | \value HostNotFoundError the remote host name was not found |
120 | (invalid hostname) |
121 | |
122 | \value TimeoutError the connection to the remote server |
123 | timed out |
124 | |
125 | \value OperationCanceledError the operation was canceled via calls |
126 | to abort() or close() before it was finished. |
127 | |
128 | \value SslHandshakeFailedError the SSL/TLS handshake failed and the |
129 | encrypted channel could not be established. The sslErrors() signal |
130 | should have been emitted. |
131 | |
132 | \value TemporaryNetworkFailureError the connection was broken due |
133 | to disconnection from the network, however the system has initiated |
134 | roaming to another access point. The request should be resubmitted |
135 | and will be processed as soon as the connection is re-established. |
136 | |
137 | \value NetworkSessionFailedError the connection was broken due |
138 | to disconnection from the network or failure to start the network. |
139 | |
140 | \value BackgroundRequestNotAllowedError the background request |
141 | is not currently allowed due to platform policy. |
142 | |
143 | \value TooManyRedirectsError while following redirects, the maximum |
144 | limit was reached. The limit is by default set to 50 or as set by |
145 | QNetworkRequest::setMaxRedirectsAllowed(). |
146 | (This value was introduced in 5.6.) |
147 | |
148 | \value InsecureRedirectError while following redirects, the network |
149 | access API detected a redirect from a encrypted protocol (https) to an |
150 | unencrypted one (http). |
151 | (This value was introduced in 5.6.) |
152 | |
153 | \value ProxyConnectionRefusedError the connection to the proxy |
154 | server was refused (the proxy server is not accepting requests) |
155 | |
156 | \value ProxyConnectionClosedError the proxy server closed the |
157 | connection prematurely, before the entire reply was received and |
158 | processed |
159 | |
160 | \value ProxyNotFoundError the proxy host name was not |
161 | found (invalid proxy hostname) |
162 | |
163 | \value ProxyTimeoutError the connection to the proxy |
164 | timed out or the proxy did not reply in time to the request sent |
165 | |
166 | \value ProxyAuthenticationRequiredError the proxy requires |
167 | authentication in order to honour the request but did not accept |
168 | any credentials offered (if any) |
169 | |
170 | \value ContentAccessDenied the access to the remote |
171 | content was denied (similar to HTTP error 403) |
172 | |
173 | \value ContentOperationNotPermittedError the operation requested |
174 | on the remote content is not permitted |
175 | |
176 | \value ContentNotFoundError the remote content was not |
177 | found at the server (similar to HTTP error 404) |
178 | |
179 | \value AuthenticationRequiredError the remote server requires |
180 | authentication to serve the content but the credentials provided |
181 | were not accepted (if any) |
182 | |
183 | \value ContentReSendError the request needed to be sent |
184 | again, but this failed for example because the upload data |
185 | could not be read a second time. |
186 | |
187 | \value ContentConflictError the request could not be completed due |
188 | to a conflict with the current state of the resource. |
189 | |
190 | \value ContentGoneError the requested resource is no longer |
191 | available at the server. |
192 | |
193 | \value InternalServerError the server encountered an unexpected |
194 | condition which prevented it from fulfilling the request. |

228 | \fn void QNetworkReply::encrypted() |
229 | \since 5.1 |
230 | |
231 | This signal is emitted when an SSL/TLS session has successfully |
232 | completed the initial handshake. At this point, no user data |
233 | has been transmitted. The signal can be used to perform |
234 | additional checks on the certificate chain, for example to |
235 | notify users when the certificate for a website has changed. |
236 | If the reply does not match the expected criteria then it should |
237 | be aborted by calling QNetworkReply::abort() by a slot connected |
238 | to this signal. The SSL configuration in use can be inspected |
239 | using the QNetworkReply::sslConfiguration() method. |
240 | |
241 | Internally, QNetworkAccessManager may open multiple connections |
242 | to a server, in order to allow it process requests in parallel. |
243 | These connections may be reused, which means that the encrypted() |
244 | signal would not be emitted. This means that you are only |
245 | guaranteed to receive this signal for the first connection to a |
246 | site in the lifespan of the QNetworkAccessManager. |

257 | \a errors parameter contains the list of errors. |
258 | |
259 | To indicate that the errors are not fatal and that the connection |
260 | should proceed, the ignoreSslErrors() function should be called |
261 | from the slot connected to this signal. If it is not called, the |
262 | SSL session will be torn down before any data is exchanged |
263 | (including the URL). |
264 | |
265 | This signal can be used to display an error message to the user |
266 | indicating that security may be compromised and display the |
267 | SSL settings (see sslConfiguration() to obtain it). If the user |
268 | decides to proceed after analyzing the remote certificate, the |
269 | slot should call ignoreSslErrors(). |

280 | ciphersuite, and therefore a PSK authentication is then required. |
281 | |
282 | When using PSK, the client must send to the server a valid identity and a |
283 | valid pre shared key, in order for the SSL handshake to continue. |
