Wechat applet - requestsubscribemessage:fail can only be invoked by user tap gesture

Preface

Use wx.requestSubscribeMessage() API, Call up the client applet subscription message interface , Has been an error ：

requestSubscribeMessage:fail can only be invoked by user TAP gesture.
# requestSubscribeMessage:fail It can only be called by the user's click gesture .

And no error code , As shown in the figure below ：

Solution

actually , It's just that API You placed Callback function in , Just place it on the outside .

for example , My error code example , Because it is placed in the callback function , As shown in the following code ：

//  I need to call the interface , Get the template id, So it is set in the callback function .
$http.fly.get('index.php', data).then((res) => {
    
   // wx.requestSubscribeMessage({})
})

Just move it outside the callback function , As shown in the following code ：

$http.fly.get('index.php', data).then((res) => {
    
   // ...
})

//  Put it outside 
wx.requestSubscribeMessage({
    
	// ...
})
