Question

我试图以html格式上传带有一些文字和数字类型的图片。在前端，我在后端使用angularjs和rest jersey。我的问题是当我试图坚持我的对象＆＃34; Vehicule＆＃34;它包含一个byte []图像。为此我在角度控制器中使用资源指令，但是当我尝试提交表单时出现此错误＆＃34;无法将VALUE_STRING解码为base64（MIME-NO-LINEFEEDS）：非法字符＆＃ 39;：＆＃39; （代码0x3a）在base64内容＆＃34;我有任何想法，因为我是角度和休息球衣的初学者。为此，这是我的代码：

@JsonIgnoreProperties(ignoreUnknown = true)
@Entity
public class Vehicule implements Serializable {

private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@Column
String marque;
@Column
String nom;
@Column
String numMat;
@Column
Long nbChevaux;
@Column
Long annee;
//@Type(type="org.hibernate.type.StringClobType")
@Column(length=100000)
byte[] image=null;
@Column(unique=true) 
Long marqueur=null;
public Long getMarqueur() {
    return marqueur;
}
public void setMarqueur(Long marqueur) {
    this.marqueur = marqueur;
}
public Long getAnnee() {
    return annee;
}
public void setAnnee(Long annee) {
    this.annee = annee;
}
public byte[] getImage() {
    return image;
}
public void setImage(byte[] image) {
    this.image = image;
}
public Long getId() {
    return id;
}
public void setId(Long id) {
    this.id = id;
}
public String getMarque() {
    return marque;
}
public void setMarque(String marque) {
    this.marque = marque;
}
public String getNom() {
    return nom;
}
public void setNom(String nom) {
    this.nom = nom;
}
public String getNumMat() {
    return numMat;
}
public void setNumMat(String numMat) {
    this.numMat = numMat;
}
public Long getNbChevaux() {
    return nbChevaux;
}
public void setNbChevaux(Long nbChevaux) {
    this.nbChevaux = nbChevaux;
}
    @Override
public int hashCode() {
    final int prime = 31;
    int result = 1;
    result = prime * result + ((id == null) ? 0 : id.hashCode());
    return result;
}
@Override
public boolean equals(Object obj) {
    if (this == obj)
        return true;
    if (obj == null)
        return false;
    if (!(obj instanceof Vehicule))
        return false;
    Vehicule other = (Vehicule) obj;
    if (id == null) {
        if (other.id != null)
            return false;
    } else if (!id.equals(other.id))
        return false;
    return true;
}
}
@Component
@Path("/vehicules")
public class Vehicules {

 private final Logger logger = LoggerFactory.getLogger(this.getClass());

    @Autowired
    private VehiculeDao vehiculeDao;
    @GET
    @Produces(MediaType.APPLICATION_JSON)
    public List<Vehicule> vehiculesList()

{
        return vehiculeDao.getAll();

}

   @POST
   @Produces(MediaType.APPLICATION_JSON)
   @Consumes(MediaType.APPLICATION_JSON)
   public Vehicule createVehicule(Vehicule vehicule)

{
       this.logger.info("create(): " + vehicule);
       return this.vehiculeDao.save(vehicule);
   }

}

function CreateVehiculeController($scope, $routeParams, $location, VehiculesService)

{

    $scope.vehicule = new VehiculesService();
$scope.save = function() {
$scope.vehicule.$save(function() {
$location.path('/');

}

Answer 1

使用window.btoa(your_image_as_binary_string);作为提交给控制器的值。

无法将VALUE_STRING解码为base64（MIME-NO-LINEFEEDS）
