NAME

6       Mail::JMAPTalk - Basic interface to talk to JMAP Servers
7

VERSION

9       Version 0.15
10

SYNOPSIS

12       Mail::JMAPTalk was originally written as a very small wrapper around
13       HTTP::Tiny to talk to a JMAP server and mapping between Perl hashes and
14       JSON on the wire.
15
16       It doesn't do anything smart with specific JMAP objects.
17
18       Example:
19
20           use Mail::JMAPTalk;
21           use JSON;
22
23           # using basic auth
24           my $jtalk = Mail::JMAPTalk->new(
25               url => "https://jmap.example.com/",
26               user => "foo\@example.com",
27               password => "letmein",
28           );
29
30           # using non-standard JMAPAuth token establishment
31           my $jtalk = Mail::JMAPTalk->new(
32               url => "https://jmap.example.com/",
33           );
34           $jtalk->Login("foo\@example.com", "letmein");
35
36           my $res = $jtalk->Call('Mailbox/get');
37           my %byname = map { $_->{name} -> $_->{id} } @{$res->{ids});
38
39           my $data = $jtalk->Upload($emailbytes, 'message/rfc822');
40           $res = $jtalk->CallMethods([['Email/import', {
41               emails => {
42                   "1" => {
43                       blobId => $data->{blobId},
44                       keywords => { '$seen' => JSON::true },
45                       mailboxIds => { $byname{Inbox} => JSON::true },
46                   },
47               },
48           }, "R1"], ["Email/get", { ids => ["#1"] }, "R2" ]]);
49           # all properties of the email in $res->[1][1]{list}[0]
50
51           my $response = $jtalk->Download($res->[1][1]{accountId}, $data->{blobId});

SUBROUTINES/METHODS

54   $class->new(%Options)
55       Create a new Mail::JMAPTalk object.
56
57       Takes options for a variety of purposes:
58
59       Override the UserAgent used for all connections:
60
61        * ua => HTTP::Tiny->new(...)
62
63       Host Options:
64
65        * scheme => 'http' or 'https' (default 'http')
66        * host => hostname (default 'localhost')
67        * port => port number (default 443 for https, otherwise 80)
68
69       URI Options: (absolute URI, or use options above to set the scope)
70
71        * authurl => auth endpoint (default '/jmap/auth/')
72        * uploadurl => upload endpoint (default '/jmap/upload/{accountId}/')
73        * downloadurl => download endpoint (default '/jmap/download/{accountId}/{blobId}/{name}')
74        * url => JMAP API endpoint (default '/jmap/')
75
76       Authentication Options: (basic auth)
77
78        * user => $username
79        * password => $password
80
81       Request Defaults:
82
83        * using => \@urns (default ['urn:ietf:params:jmap:core', 'urn:ietf:params:jmap:mail'])
84
85   my $ua = $Self->ua();
86   $Self->ua($setua);
87       Get or set the useragent (HTTP::Tiny or compatible) that will be used
88       to make the requests:
89
90       e.g.
91
92           my $ua = $Self->ua();
93
94           $Self->ua(HTTP::Tiny->new(agent => "MyAgent/1.0", timeout => 5));
95
96   my $header = $Self->auth_header();
97       Returns the basic-auth value for the 'Authentication' header.
98
99   my $uri = $Self->authuri();
100       Returns the URI for JMAPAuth authentication (non-standard).  Default
101       depends on the parameters passed to new.  Most simple would be:
102
103           http://localhost/jmap/auth/
104
105   my $uri = $Self->uploaduri($accountId);
106       Returns the URI for JMAP uploads.  Default depends on the parameters
107       passed to new.  Most simple would be:
108
109           http://localhost/jmap/upload/${accountId}/
110
111   my $uri = $Self->downloaduri($accountId, $blobId, $name);
112       Returns the URI for JMAP downloads.  Default depends on the parameters
113       passed to new.  Most simple would be:
114
115           http://localhost/jmap/download/${accountId}/${blobId}/{$name}
116
117       Where name is utf8 and uri encoded to be safe.
118
119   my $uri = $Self->uri()
120       Returns the URI for JMAP API Calls.  Default depends on the parameters
121       passed to new.  Most simple would be:
122
123           http://localhost/jmap/
124
125   my $uri = $Self->JSONPOST($Uri, $Request, %Headers)
126       Makes a POST request to the given URI with the body being the value of
127       $Request (which must be a reference) encoded as JSON, and with the
128       Headers added.
129
130       Will set Content-Type and Accept headers to 'application/json' unless
131       overridden.
132
133       Generally you won't call this directly, but through one of the helper
134       methods.
135
136       This method will die if the response is not successful or does not
137       contain valid json.
138
139   $Self->AuthRequest($Request, %Headers)
140       Makes a JSONPOST request to the authurl.
141
142   $Self->Login($Username, $Password)
143       Uses the non-standard JMAPAuth protocol to login.
144
145       On success will set the upload, download and api urls as well as a
146       token which is used to authenticate all further requests.
147
148       On failure will die.
149
150   $Self->Request($Request, %Headers)
151       Makes a JSONPOST request to the API url, authenticated with either the
152       basic auth parameters given at creation, or the token obtained via
153       Login.
154
155   my $using = $Self->DefaultUsing()
156   $Self->DefaultUsing(\@urns)
157       Returns or replaces the default 'using' value for method calls.
158
159   $Self->AddUsing(@urns)
160       Appends any urns given to the default 'using' if they aren't already
161       registered.
162
163   $Self->CallMethods($MethodCalls, $Using, %Headers)
164       Generates a JMAP request from the given method calls, optionally
165       overriding the using and header values.
166
167       MethodCalls is an array of arrays, each of the sub arrays is a single
168       "Invocation" per RFC8620 as follows:
169
170          3.2.  The Invocation Data Type
171
172          Method calls and responses are represented by the *Invocation* data
173          type.  This is a tuple, represented as a JSON array containing three
174          elements:
175
176          1.  A "String" *name* of the method to call or of the response.
177
178          2.  A "String[*]" object containing named *arguments* for that method
179              or response.
180
181          3.  A "String" *method call id*: an arbitrary string from the client
182              to be echoed back with the responses emitted by that method call
183              (a method may return 1 or more responses, as it may make implicit
184              calls to other methods; all responses initiated by this method
185              call get the same method call id in the response).
186
187       In perl, this is [string, hashref, string].
188
189       Example:
190
191           my $res = $jtalk->CallMethods([
192               ['Email/query', { }, 'R1'],
193               ['Email/get', {
194                   '#ids' => {
195                       resultOf => 'R1',
196                       name => 'Email/query',
197                       path => '/ids'
198                   },
199                   properties => [ 'subject', 'header:x-mood:asText', 'from', 'to' ],
200               }, 'R2'],
201           ]);
202
203       The response is an arrayref containing the value of methodResponses
204       from the JSON reply defined in JMAP.
205
206       This method will die if the server returns an error or invalid JSON.
207
208   $Self->Call($Method, $Params, $Using, %Headers)
209       A convenience method to call a single method.  This method generates a
210       single invocation with call id 'c1' and will return undef unless the
211       first response from the server has the same method name (i.e. is not an
212       error) and the same call id.
213
214       The return value is the response section (middle field) of the first
215       methodResponse Invocation object.
216
217       Example:
218
219           my $res = $jtalk->Call('Calendar/get', { properties => ['name'] });
220           my %byname = map { $_->{name} => $_->{id} } @{$res->{list}};
221
222   $Self->Upload($data, $mimetype, $accountId)
223       Uploads the bytes in $data with either the given mimetype or if the
224       mimetype is not given, the type picked by File::LibMagic.
225
226       The POST request is authenticated with either the basic auth parameters
227       given at creation, or the token obtained via Login.
228
229       If called in scalar context, will die unless the request was successful
230       - and returns a hashref with the content returned by the server as
231       defined in RFC8620:
232
233          A successful request MUST return a single JSON object with the
234          following properties as the response:
235
236          o  accountId: "Id"
237
238             The id of the account used for the call.
239
240          o  blobId: "Id"
241
242             The id representing the binary data uploaded.  The data for this
243             id is immutable.  The id *only* refers to the binary data, not any
244             metadata.
245
246          o  type: "String"
247
248             The media type of the file (as specified in [RFC6838],
249             Section 4.2) as set in the Content-Type header of the upload HTTP
250             request.
251
252          o  size: "UnsignedInt"
253
254             The size of the file in octets.
255
256       If called in array context, returns two values - the first is the raw
257       HTTP::Tiny response hash, and the second is the JSON as above.
258
259       Example:
260
261           my ($Response, $data) = $jtalk->Upload($bytes);
262           if ($Response->{success}) {
263               say "Uploaded $data->{size} bytes as $data->{blobId}";
264               ...
265           }
266
267   $Self->Download($cb?, $Headers?, $accountId, $blobId, $name)
268       Makes a GET request authenticated with either the basic auth parameters
269       given at creation, or the token obtained via Login.
270
271       If the first argument is a code reference, it will be shifted and used
272       as the data_callback (see HTTP::Tiny).
273
274       Then - if the first argument is a hash reference, it will be shifted
275       and used as additional headers.
276
277       Then - the remaining parameters are passed to $Self->downloadurl() to
278       generate the link to download.
279
280       The response is a HTTP::Tiny Response object.
281
282       Example:
283
284           my $res = $jtalk->Download($accountId, $data->{blobId}, "image.gif");
285           if ($res->{success}) {
286               open(FH, ">image.gif");
287               print FH $res->{content};
288               close(FH);
289           }
290

ENVIRONMENT

292       If the environment variable DEBUGJMAP is set to a true value, all API
293       requests and responses plus Upload responses will be warn()ed.
