Micro-channel document, https: //developers.weixin.qq.com/doc/offiaccount/OA_Web_Apps/JS-SDK.html,
Share with the custom micro letter, met a few pit, record it.
Note Point 1: Go to "Settings Public No." "functional settings" fill in "JS interface security domain." No authentication is required public attention, otherwise you may be prompted to use interface has no authority;
Note point 2: access_token is a globally unique interface call number of public credentials, the effective time of 2 hours, pay attention to the cache, can not always get a new, 2,000 times a day can be cached, or stored in a data table, determine the current time with the time and into the time difference. It is more than can be emptied in the number of micro letter backstage interfaces permissions, can only clean three times a month .
Wherein the jsapi_ticket is, the cache memory or table.
Note point 3: The signature of Notes
Note point 4: url when the signature, in micro-channel pc's, url no stitching nothing, and in the micro-channel phone's automatically stitching on your current page circle of friends from = timeline, micro-channel group from = groupmessage, friends to share = singlemessage from , should pay attention to when signing, do not miss, can be in the foreground ajax request, or url of the current page, passing in the background signature.
Notes 5:
In the mobile micro-letter, these interfaces, it has been abandoned, used, it will prompt does not support, and in the pc micro letter, or use them, not with the new
Due to the different methods pc and mobile phone use, as defined in php in two sets, a set of open access using a mobile phone, access to a pc when open, or get access to address a completely different page, pc an address, a phone address
Here is the definition of php, although the phone and pc is the same URL, but the real visit or two
