disable range request in iPhone #7824
Conversation
Better way but NOT necessarily best way to solve the IOS webview APP error: Unexpected server response (206) while retrieving PDF... Details: 1. At the beginning, I only found the Error in IOS WeChat APP, so I solved it by checking WeChat: 9ad57d4 2. But I found this error in other IOS app, so I checked UA details of them as follow: a) iPhone WeChat APP UserAgent (Fail): Mozilla/5.0 (iPhone; CPU iPhone OS 10_1_1 like Mac OS X) AppleWebKit/602.2.14 (KHTML, like Gecko) Mobile/14B100 MicroMessenger/6.3.30 NetType/WIFI Language/zh_CN b) iPhone Other APP UserAgent (Fail): Mozilla/5.0 (iPhone; CPU iPhone OS 10_1_1 like Mac X) AppleWebKit/602.2.14 (KHTML, like Gecko) Mobile/14B100 QYZone Maybe all webview app in IOS 10 have this problem, and since Safari & Chrome in IOS also does NOT support range request in IOS, so I think it's a better way to disable range request in iPhone by this regex: var isIPhone = /iPhone/.test(navigator.userAgent); if (isIPhone) { PDFJS.disableRange = true; PDFJS.disableStream = true; } solve issues: mozilla#7815 mozilla#7754 mozilla#7800

Wouldn't the same problem apply to e.g. iPads as well?
Also, as mentioned in http://stackoverflow.com/questions/9038625/detect-if-device-is-ios: just checking for iPhone can incorrectly match some versions of Internet Explorer too, which we should avoid.

Better way but NOT necessarily best way to solve the IOS webview APP error: Unexpected server response (206) while retrieving PDF...
Details:
At the beginning, I only found the Error in IOS WeChat APP, so I solved it by checking WeChat:
godwin668@9ad57d4
But I found this error in other IOS app, so I checked UA details of them as follow:
a) iPhone WeChat APP UserAgent (Fail):
Mozilla/5.0 (iPhone; CPU iPhone OS 10_1_1 like Mac OS X) AppleWebKit/602.2.14 (KHTML, like Gecko) Mobile/14B100 MicroMessenger/6.3.30 NetType/WIFI Language/zh_CN
b) iPhone Other APP UserAgent (Fail):
Mozilla/5.0 (iPhone; CPU iPhone OS 10_1_1 like Mac X) AppleWebKit/602.2.14 (KHTML, like Gecko) Mobile/14B100 QYZone
Maybe all webview app in IOS 10 have this problem, and since Safari & Chrome in IOS also does NOT support range request in IOS, so I think it's a better way to disable range request in iPhone by this regex:
var isIPhone = /iPhone/.test(navigator.userAgent);
if (isIPhone) {
PDFJS.disableRange = true;
PDFJS.disableStream = true;
}
