Question

我正在尝试使用S3签名的URL从Ionic应用程序上传图像，最令人困惑的部分是相同的代码在iOS上有效，但在Android上无效。

我的应用程序使用的是cordova-plugin-advanced-http，cordova-plugin-camera和cordova-plugin-file。

my-component.ts

openPhotoLibrary() {
    this.loadingProvider.showLoader('Aguarde');
    this.viewCtrl.dismiss();
    this.camera.getPicture(this.photoLibraryOptions).then((fileURI) => {
      this.file.resolveLocalFilesystemUrl(fileURI).then(
        (fileEntry: FileEntry) => {
          console.log('resolveLocalFilesystemUrl');
          console.log(fileEntry);

          fileEntry.file((file) => {
            console.log('file');
            console.log(file);
            let newName = uuid().concat('.jpg');
            console.log('newName');
            console.log(newName);

            this.myProvider.getImageUploadUrl(newName, this.JPEG_CONTENT_TYPE).then(
              (res) => {
                let responseData = JSON.parse(res.data);

                console.log('getImageUploadUrl');
                console.log(responseData);
                console.log('FILE THAT WILL BE SENT -> ', file);

                this.myProvider.uploadImage(responseData.data, file, this.JPEG_CONTENT_TYPE).then(
                  (data) => {
                    console.log('uploadImage');
                    console.log(data);
                    this.loadingProvider.hideLoader();
                  }, (error) => {
                    console.error('uploadImage error: ', error);
                    this.loadingProvider.hideLoader();
                  }
                );
              }, (error) => {
                console.error('getImageUploadUrl error: ', error);
              });
            }, (error) => {
              console.error('fileEntry.file error: ', error);
            }
          );
        }, (error) => {
          console.error('resolveLocalFilesystemUrl error: ', error);
        }
      );
     }, (error) => {
      console.error(error);
     });
  }

my-provider.ts

getImageUploadUrl(fileName: string, fileType: string) {
    const phoneNumber = this.storage.getPhoneNumber();
    const userToken = this.storage.getToken();
    return this.http.get(
      `${API_ROOT}chatimages/getImageUploadUrl?fileName=${fileName}&fileType=${fileType}`, {}, {
        'Authorization': userToken,
        'phoneNumber': phoneNumber
      }
    );
  }

  uploadImage(url: string, image: IFile, imageType: string) {
    console.log('URL');
    console.log(url);
    let host = url.split('?')[0] + '?' + decodeURIComponent(url.split('?')[1]);
    console.log('HOST');
    console.log(host);
    let headers = { 'Accept': '*/*', 'Content-Type': imageType };
    return this.http.put(host, image, headers);
  }

我希望相同的代码在Android上也可以使用，但是我正在尝试解决Android上的此响应错误，当我从提供者处调用uploadImage时，就会发生此错误：
