Basic steps for exporting excel tables through vue call backend interface

Export Excel tables through Vue call backend interface in the front end, you can follow the steps below.

In Vue components, a request is sent to the backend through Vue's HTTP request library (such as axios) and a download link for the generated Excel file is obtained. You can define a click event in the component that triggers when the user clicks the Export button.

In the handler function of the click event, use axios to send a request to the backend interface. You need to specify the requested url and request method (such as GET or POST) and pass the parameters as needed.

For example, you can use the following code to send a GET request:

('/api/export/excel', {
  params: {
    // If there are parameters that need to be passed to the backend, you can add them here  },
  responseType: 'blob'  // Specify the response's data type as binary stream}).then(response => {
  // After the request returns successfully, get the binary data of the Excel file  const blob = new Blob([], { type: 'application/-excel' });
  // Create a download link  const downloadUrl = (blob);
  // Create a hidden A tag, set the download link and file name, simulate click to download  const link = ('a');
   = 'none';
   = downloadUrl;
   = '';
  (link);
  ();
  (link);
}).catch(error => {
  // Request failed processing  (error);
});

Please make appropriate modifications based on your specific backend interface definition and parameter requirements.

After the backend interface processes the request, an Excel file is generated based on the received parameters and exported. You can use related libraries/tools to handle the generation of Excel files, such asexceljsModules, Pythonopenpyxletc. The specific choice is determined according to your backend language.

Through the above steps, you can call the backend interface in the front end through Vue to generate and export Excel tables. Remember to adapt the suffix and MIME type of the Excel file to ensure that the file is downloaded and opened normally.
