基于cordova插件的上传下载

基于cordova的上传下载

1.准备工作：添加插件（cordova.plugin.file，cordova.plugin.file-transfer）依赖

2.调用方法实现上传下载（上代码）

1.调用插件进行下载

function download(fileEntry, uri) {
    
    
  var fileTransfer = new FileTransfer();
  var fileURL = fileEntry.toURL();

  fileTransfer.download(
      uri,
      fileURL,
      function (entry) {
    
    
          console.log("下载成功！");
          console.log("文件保存位置: " + entry.toURL());
      },
      function (error) {
    
    
          console.log("下载失败！");
          console.log("error source " + error.source);
          console.log("error target " + error.target);
          console.log("error code" + error.code);
      },
      null, // or, pass false
      {
          //headers: {
    
    
          //    "Authorization": "Basic dGVzdHVzZXJuYW1lOnRlc3RwYXNzd29yZA=="
          //}
      }
  );
}

2.调用插件进行上传

function upload(fileEntry) {
    
    
  //获取文件的url路径地址
  var fileURL = fileEntry.toURL();

  //上传成功
  var success = function (r) {
    
    
      console.log("上传成功! Code = " + r.responseCode);
  }

  //上传失败
  var fail = function (error) {
    
    
      alert("上传失败! Code = " + error.code);
  }

  var options = new FileUploadOptions();
  options.fileKey = "file1";
  options.fileName = fileURL.substr(fileURL.lastIndexOf('/') + 1);
  options.mimeType = "text/plain";

  //上传参数
  var params = {};
  params.value1 = "test";
  params.value2 = "param";
  options.params = params;

  var ft = new FileTransfer();
  //上传地址
  var SERVER = "http://www.hangge.com/upload.php"
  ft.upload(fileURL, encodeURI(SERVER), success, fail, options);
}

3.上传下载完成
