[Solved] echarts Draw Errror: echarts-d9fd185e.js:31447 Uncaught (in promise) Error: Initialize failed: invalid dom.

When the browser executes document.getElementById(‘chart’), because the dom object with the id of main has not been created, it reports an error Initialize failed: invalid dom.

The solution is to delay the execution of the code for initializing the charts in echarts, which is fast and does not affect the display of the effect and does not feel stuck.

func.echarts() for the initialization of the chart function , code and effects are as follows (a vue3.0 project of a page used)

     echarts: () => {
        let myChart = echarts.init(document.getElementById("chart"));
        let option = {
          title: {
            text: '标题',
            textStyle: {
              fontSize: 13
            },
          },
          toolbox: {
            show: true,
            feature: {
              saveAsImage: {
                show: false
              }
            },
          },
          legend: {
            data: ['人数']
          },
          xAxis: {
            data: ['09-14', '09-15', '09-16', '09-17', '09-18', '09-19', '09-20']
          },
          yAxis: {},
          series: [{
            name: '人数',
            type: 'line',
            data: ['13', '14', '18', '14', '10', '11', '9'],
          }]
        };
        myChart.setOption(option);
      },
    })

[Solved] Uncaught Error: Highcharts error #16

Highcharts error #16 is due to duplicate Highcharts definitions. The reason for this error is that the namespace of Highcharts is duplicated.

The namespace of Highcharts actually exists in the Highcharts.js file that we refer to when we use Highcharts.

Solution
Remove the Highcharts.js from the nested subpages and leave only the reference to the main page, and the error will not be reported.

Conclusion
Referencing Highcharts.js on the main page and referencing Highcharts.js on the sub-page nested in it will cause duplicate Highcharts definitions whenever the sub-page is loaded.

How to Fix LDPlayer4 Proxy Setting Not Work Issue

Leave a reply

Enter the installation directory D:\Program Files\leidian\LDPlayer4
powershell
.\adb
cmd
adb

if it appears

adb shell
error: more than one device and emulator

In this case, the first thing to check is whether there are really multiple devices or emulators.

adb devices
List of devices attached
emulator-5554 device
127.0.0.1:5555 device
It is found that there are multiple devices, then you need to specify the serial number of the device for the ADB command.
adb -s emulator-5554 shell

That is, as shown above, just add the -s parameter to the command!

If there is actually only one device or simulator, and the offline status is found;
it means that it is caused by a bug in ADB itself, and it needs to be dealt with as follows:
adb kill-server
taskkill /f /im adb The first command of .exe
is to kill the ADB service, and the second command is to kill the ADB process!
If the first one doesn’t work, consider using the second one to try again!

Finally execute this command to
set the proxy,
.\adb -s 127.0.0.1:5555 shell settings put global http_proxy 192.168.0.72:8888
remove the proxy
adb shell settings delete global http_proxy&adb shell settings delete global global_http_proxy_host&adb shell settings delete global global_http_proxy_port
or when there is no delete command
adb shell settings put global http_proxy :0

How to Check the appPackage or appActivity of an APK

Leave a reply

Here is a simple guide on how to check the appPackage and appActivity in apk.

 

How to Check the appPackage or appActivity of an APK

Option 1:

  1. aapt dump badging xxxx.apk
  2. Lookup “package: name” and “launchable-activity: name” in terminal’s output

Option 2:

  1. java -jar apktool_2.3.3.jar d xxxx.apk
  2. Lookup appPackage and appActivity in AndroidManifest.xml

[Solved] CXF Call webservice Client Error: 2 counts of InaccessibleWSDLException

Leave a reply

Background
The webservice service is used for interface communication in the project. In the specific application, the caller does not access the service directly, but forwards the request through a proxy to achieve access.

Problem
The client code generated by using apache axis1.4 tool to invoke the service can be accessed normally; the client code generated by using apache cxf tool reports an error: 2 counts of InaccessibleWSDLException.

Reason
The client code of axis is written with service name, port type and other information fixed in the generated code, while the client code of cxf is parsed by GET to get the wsdl file and bind service name and port name and other information before calling the interface.

image

In the project, because the proxy redirection interface address is used, the wsdl file cannot be directly obtained through GET for parsing, so an error is reported.

Solution:

  • a. Store the wsdl file locally, read the local wsdl file in the client, and fill in the address of the actual interface in the soap address label in the wsdl file
<service name="xxxService">
   <port binding="xxxSOAPBinding" name="xxxSOAPPort">
      <soap:address location="http://yourActualAddress/xxxService"/>
   </port>
</service>
  • b. Change the calling code to skip the step of getting the wsdl.
xxxService ss = new xxxService(null, SERVICE_NAME);
XXXServicePortType port = ss.getPort(xxxServicePortType.class);

BindingProvider bindingProvider = (BindingProvider) port;
bindingProvider.getRequestContext()
  .put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY,
    "http://www.example.com/real_endpoint_url_goes_here");
Response res = port.yourMethods(...);
