Cordova FileUploadOptions 参数未在 iOS 上发布

Question

使用使用 build.phonegap.com 构建的应用程序，我发现 FileUploadOptions.params 值未发布 - iOS (8.4.1) 仅发布文件多部分数据。这不是服务器端错误，因为我看过 POST 使用 tcpdump/Wireshark 和 netcat。

使用：

PhoneGap v.3.7.0
离子框架 v.1.0.1
AngularJS v.1.3.13

这是用于上传测试文件的代码。它会生成一个临时文件并尝试上传它。问题是，我是不是弄错了什么，或者这是一个真正的错误？

  $scope.doUploadTest = function() {
    var q = $q.defer();
    var promise = q.promise;

    var text = "Test file content: " + new Date();

    $window.requestFileSystem(LocalFileSystem.TEMPORARY, text.length, function(fs) {
      q.resolve(fs);
    }, function(err) {
      q.reject(err);
    });

    promise
    .then(function(fs) {
      var qFile = $q.defer();

      fs.root.getFile("upload.tmp", {create: true, exclusive: false}, function(entry) {
        qFile.resolve(entry);
      }, function(err) {
        qFile.reject(err);
      });

      return qFile.promise;
    })
    .then(function(entry) {
      console.log("got file: " + entry.nativeURL);

      var qWriter = $q.defer();

      entry.createWriter(function(writer) {
        qWriter.resolve({writer: writer, entry: entry});
      }, function(err) {
        qWriter.reject(err);
      });

      return qWriter.promise;
    })
    .then(function(response) {
      var qWrite = $q.defer();

      response.writer.onwriteend = function(evt) {
        qWrite.resolve(response.entry);
      };

      response.writer.write(text);

      return qWrite.promise;
    })
    .then(function(entry) {
      $scope.error = entry;

      var qUpload = $q.defer();

      var options = new FileUploadOptions();
      options.params = {
        Value: {
          list: [1, 2, 3],
          text: "foo bar baz",
          number: 1234
        }
      };
      options.fileKey = "thefile";
      options.fileName = entry.name;
      options.mimeType = "text/plain";
      options.chunkedMode = false;
      options.headers = {
        "X-Upload": (new Date()).toString()
      };


      var ft = new FileTransfer();
      ft.upload(entry.nativeURL, "http://192.168.0.30:9100/", function(success) {
        entry.remove();
        qUpload.resolve(success);
      }, function(err) {
        entry.remove();
        qUpload.reject(err);
      }, options);

      // Abort after 3 seconds
      $timeout(function() {
        console.log("Aborting upload - timed out");
        ft.abort();
      }, 3000);

      return qUpload.promise;
    })
    .then(function(response) {
      console.log("Upload succeeded");
      $scope.error = response;
    })

    .catch(function(err) {
      console.log("Upload failed");
      $scope.error = err;
    });
    ;


  };

在 iPhone 6 (iOS v.8.4.1) 上提出的请求如下：

Answer 1

事实证明，params 对象只能包含 literal 属性，不能包含对象。 documentation 仅使用字符串值，但未明确说明不支持对象。

由于在 Android 上插件将对象序列化为 JSON 字符串，而在 iOS 上插件默默地转储它，因此这变得更加复杂。

所以，解决方案就是先序列化数据：

  var options = new FileUploadOptions();
  options.params = {
    Value: JSON.stringify({
      list: [1, 2, 3],
      text: "foo bar baz",
      number: 1234
    })
  };
