WeixinJSBridge: JavaScript bridge tool for WeChat browser

WeixinJSBridge is a JavaScript bridging tool provided in WeChat's built-in browser, which allows developers to call functions and interfaces of WeChat client in web pages. By using WeixinJSBridge, developers can interact with the WeChat client to achieve more functions and customization.

The role of WeixinJSBridge

WeixinJSBridge allows developers to communicate directly with the WeChat client in the web page, and call the interface and functions of WeChat in the browser. It greatly increases the functional scalability of WeChat's built-in browser and brings more possibilities for developers.

Through WeixinJSBridge, developers can realize the following functions:

Invoke WeChat sharing: Developers can use WeixinJSBridge to call the sharing interface of the WeChat client to share content directly to WeChat Moments or friends on the web page.
Invoke the payment function: By using the WeixinJSBridge.invoke method, developers can initiate a WeChat payment request in the web page to realize the payment function.
Obtain device information: With WeixinJSBridge, developers can obtain device information of the WeChat client, such as device model, operating system version, WeChat version, etc.
Scanning function: Through WeixinJSBridge, developers can call the scanning function of the WeChat client to scan QR codes or barcodes on web pages.

Use of WeixinJSBridge

To use WeixinJSBridge, you need to load WeixinJSBridge related scripts in the web page, and perform related operations after the scripts are loaded. In general, you can listen to the WeixinJSBridgeReady event and perform related operations in the event callback function.

The following is a simple sample code that demonstrates how to use WeixinJSBridge to call the WeChat sharing function:

document.addEventListener('WeixinJSBridgeReady', function() {
    WeixinJSBridge.invoke('shareTimeline', {
        "title": "分享标题",
        "link": "http://example.com",
        "img_url": "http://example.com/img.jpg"
    }, function(res) {
        // 分享结果的回调处理
        if (res.err_msg == 'share_timeline:ok') {
            // 分享成功
        } else {
            // 分享失败
        }
    });
}, false);

In the above code, we call the WeixinJSBridge.invoke method in the WeixinJSBridgeReady event callback function and pass in the parameters related to sharing. When the user clicks the share button, the WeChat client will pop up the sharing interface. After the user completes the sharing, the WeChat client will pass the sharing result to the web page, and can perform corresponding follow-up processing according to the result

Summarize

WeixinJSBridge is a JavaScript bridging tool provided by WeChat's built-in browser. Developers can use it to call the interface and functions of WeChat client in web pages. By using WeixinJSBridge, developers can implement more customized functions and improve user experience. Hope this article helps you understand WeixinJSBridge!

WeixinJSBridge.invoke initiates payment

       } else {
           // 支付失败的逻辑处理
       }
   });
}, false);

In the above example, WeixinJSBridgeReady is the callback function prepared by WeixinJSBridge, and the WeixinJSBridge.invoke method is called inside the callback function. In getBrandWCPayRequest parameters, we need to pass in some payment-related parameters, such as appId, timeStamp, nonceStr, package, etc.

After calling the WeixinJSBridge.invoke method, the WeChat client will pop up a payment interface, and the user can complete the payment operation in this interface. After the payment is completed, the WeChat client will return the corresponding result to the web page, and corresponding follow-up processing can be performed according to the result.
