## Description

The ESoupSession is a SoupSession descendant, which hides common tasks related to the way evolution-data-server works.

## Functions

### e_soup_session_error_quark ()

    GQuark
    e_soup_session_error_quark (void);

### e_soup_session_new ()

    ESoupSession *
    e_soup_session_new (ESource *source);

Creates a new ESoupSession associated with given `source` . The `source` can be used to store and read SSL trust settings, but only if it already contains an ESourceWebdav extension. Otherwise the SSL trust settings are ignored.

#### Parameters

source | an ESource |

#### Returns

a new ESoupSession; free it with `g_object_unref()`, when no longer needed.

### e_soup_session_send_message ()

    void
    e_soup_session_send_message (ESoupSession *session,
                                 SoupMessage *message,
                                 gint io_priority,

                                 gpointer user_data);

Asynchronously sends the `message` . Finish the call with `e_soup_session_send_message_finish()`.

The `prepare_data` is a result of the `e_soup_session_prepare_message_send_sync()` and this function assumes ownership of it. The `prepare_data` cannot be used again after this call.

#### Parameters

session | an ESoupSession |
message | a SoupMessage to send |
io_priority | the I/O priority of the request, like `G_PRIORITY_DEFAULT` |
prepare_data | data returned from `e_soup_session_prepare_message_send_sync()`. | [transfer full]
cancellable | optional GCancellable object, or `NULL` |
callback | the callback to invoke once the request is finished. | [scope async]

### e_soup_session_send_message_finish ()

    GInputStream *
    e_soup_session_send_message_finish (ESoupSession *session,
                                        GAsyncResult *result,
                                        gchar **out_certificate_pem,
                                        GTlsCertificateFlags *out_certificate_errors,
                                        GError **error);

Finishes the call of `e_soup_session_send_message()`. This is supposed to be called from the callback passed to the `e_soup_session_send_message()`.

The optional `out_certificate_pem` and `out_certificate_errors` are set, when provided, only if the operation failed with a TLS/SSL error.

Make sure the GInputStream is read and freed from the same thread, and with the same thread default main context, which this function was called from, otherwise it can break libsoup3.

#### Parameters

session | an ESoupSession |
result | a GAsyncResult object |
out_certificate_pem | return location for a server TLS/SSL certificate in PEM format, when the last operation failed with a TLS/SSL error. | [out][optional][nullable]
out_certificate_errors | return location for a GTlsCertificateFlags, with certificate error flags when the operation failed with a TLS/SSL error. | [out][optional]
error | return location for a GError, or `NULL` |

#### Returns

a GInputStream for reading the response body, or `NULL` on error.

### e_soup_session_send_message_sync ()

    GInputStream *
    e_soup_session_send_message_sync (ESoupSession *session,
                                      SoupMessage *message,
                                      GCancellable *cancellable,
                                      GError **error);

Synchronously sends prepared message and returns GInputStream that can be used to read its contents.

This calls `soup_session_send()` internally, but it also setups the `message` according to “source” authentication settings. It also extracts information about used certificate, in case of G_TLS_ERROR_BAD_CERTIFICATE error and keeps it for later use by `e_soup_session_get_ssl_error_details()`.

Use `e_soup_session_send_message_simple_sync()` to read whole content into a GByteArray.

Note that SoupSession doesn't log content read from GInputStream, thus the caller may print the read content on its own when needed.

Note the `message` is fully filled only after there is anything read from the resulting GInputStream, thus use `e_soup_session_check_result()` to verify that the receive had been finished properly.

Make sure the GInputStream is read and freed from the same thread, and with the same thread default main context, which this function was called from, otherwise it can break libsoup3.

#### Parameters

session | an ESoupSession |
message | a SoupMessage to send |
cancellable | optional GCancellable object, or `NULL` |
error | return location for a GError, or `NULL` |

#### Returns

A newly allocated GInputStream, that can be used to read from the URI pointed to by `message` . Free it with `g_object_unref()`, when no longer needed.

                                    GCancellable *cancellable,
                                    GError **error);

Similar to `e_soup_session_send_message_sync()`, except it reads whole response content into memory and returns it as a GByteArray. Use `e_soup_session_send_message_sync()` when you want to have more control on the content read.

#### Parameters

session | an ESoupSession |
message | a SoupMessage to send |
cancellable | optional GCancellable object, or `NULL` |
error | return location for a GError, or `NULL` |

#### Returns

A newly allocated GByteArray, which contains whole content from the URI pointed to by `message` .

                                   (SoupMessage *message,
                                    gssize *out_length);

Returns referenced request data for the `message` , as being previously set by the `e_soup_session_util_set_message_request_body()` or `e_soup_session_util_set_message_request_body_from_data()`.

Do not call this function while the `message` is queued in a SoupSession, nor modify the input stream position until the `message` lefts the SoupSession.

#### Parameters

message | a SoupMessage |
out_length | length of the input stream. | [out][optional]

#### Returns

a new GInputStream with the request body being previously set, or `NULL`. The `out_length` is set to the length of the returned input stream.
