Java 将表单数据发送到改装中的服务器

试图通过改装将表单数据发送到服务器，但无法向服务器请求。我想发布一个带有他们数据的图像数组

 val builder: MultipartBody.Builder  =  MultipartBody.Builder().setType(MultipartBody.FORM);
            builder.addFormDataPart("device_id",device_UDID)
            builder.addFormDataPart("device_token",device_token)
            builder.addFormDataPart("device_type","android")
            builder.addFormDataPart("country_code",Constant.COUNTRY_CODE)
            builder.addFormDataPart("email",signUpBean.email)
            builder.addFormDataPart("mobile",signUpBean.phoneNumber)
            builder.addFormDataPart("first_name",signUpBean.firstName)
            builder.addFormDataPart("last_name",signUpBean.lastName)
            builder.addFormDataPart("gender",signUpBean.gender)
            builder.addFormDataPart("dob",signUpBean.dob)
            builder.addFormDataPart("city",signUpBean.city)
            builder.addFormDataPart("bike_type_id","1")
            builder.addFormDataPart("bike_model",signUpBean.mfg)
            builder.addFormDataPart("bike_manufacturer",signUpBean.mfg)
            builder.addFormDataPart("reg_year",signUpBean.mfgYear)
            builder.addFormDataPart("liecense_plate",signUpBean.licencePlateNo)
            builder.addFormDataPart("bank_ac_name",signUpBean.bnkHolderName)
            builder.addFormDataPart("bank_ac_number",signUpBean.bnkAccountNumber)
            builder.addFormDataPart("bank_name",signUpBean.bnkName)
            builder.addFormDataPart("bank_ifsc_code",signUpBean.ifscCode)
            builder.addFormDataPart("profile_pic","profile" + ".jpg", RequestBody.create(MediaType.parse("image/*"), file_profile!!))
            builder.addFormDataPart("provider_documents[0][document]","1" + ".jpg", RequestBody.create(MediaType.parse("image/*"), file_profile!!))
            builder.addFormDataPart("provider_documents[0][document_id]","1")
            builder.addFormDataPart("provider_documents[0][unique_id]","1")
            builder.addFormDataPart("provider_documents[0][exprice_at]","2010-12-12")
            val requestBody = builder.build()
                 observable = apiInterface.signUp2(requestBody)

我尝试了许多解决方案，但无法发布包含其数据的图像阵列。 当我从

addFormDataPart

中删除

provider\u文档时，它工作正常

// @Multipart
    @POST(URLHelper.register)
    fun signUp2(@Body builder: RequestBody ): Observable<Registration>

请求Api

   @Multipart
    @POST(URLHelper.register)
    fun signUp3(@PartMap photo: HashMap<String, RequestBody>,
                @PartMap ImageMap:HashMap<MultipartBody.Part>,

     ): Observable<Registration>

@Multipart
@POST（URLHelper.register）
有趣的注册3（@PartMap photo:HashMap，
@PartMap ImageMap:HashMap，
)：可见
虚拟api接口。

 public interface ApiInterface {
        @Multipart
        @POST(URLHelper.register)
        Call<ModelProp> signUp2(@Part List<MultipartBody.Part> photos,
                          @PartMap Map<String, RequestBody> map;
    }

prepareFilePart方法

public RequestBody createPartFromString(String string) {
        return RequestBody.create(MultipartBody.FORM, string);
}

private MultipartBody.Part prepareFilePart(String partName, File file){
    RequestBody requestBody = RequestBody.create(MediaType.parse("image/*"), file);

    return MultipartBody.Part.createFormData(partName, file.getName(),requestBody);
}

像这样使用它：-

// @Multipart
@POST(URLHelper.register)
fun signUp2(@Part builder: MultipartBody ): Observable<Registration>

/@Multipart
@POST（URLHelper.register）
有趣的注册2（@partbuilder:MultipartBody）：可见

更新：-

  private void uploadToServer(String filePath) {
        showProgressDialog();
        Retrofit retrofit = RetrofitClient.getRetrofitClient(this);
        ApiInterface uploadAPIs = retrofit.create(ApiInterface.class);
        File file = new File(filePath);
        //compressor.setDestinationDirectoryPath()
        RequestBody fileReqBody = RequestBody.create(MediaType.parse("image/*"), file);
        MultipartBody.Part part = MultipartBody.Part.createFormData("fileUpload", file.getName(), fileReqBody);
        //RequestBody description = RequestBody.create(MediaType.parse("text/plain"), "image-type");
        RequestBody imgNameReqBody = RequestBody.create(MediaType.parse("multipart/form-data"), "B2B_" + System.nanoTime());

        uploadAPIs.uploadImage(imgNameReqBody, part).enqueue(new Callback<UploadImageRespose>() {
            @Override
            public void onResponse(@NonNull Call<UploadImageRespose> call, @NonNull retrofit2.Response<UploadImageRespose> response) {
                if (response.isSuccessful() && response.body() != null) {
                    if (response.body().getCODE().equalsIgnoreCase("SUCCESS")) {
                        Toast.makeText(Activity.this, "Profile Image Upload Succesfully", Toast.LENGTH_SHORT).show();
                    } else {
                        hideProgressDialog();
                        Toast.makeText(Activity.this, "Some Error  occurred, try again", Toast.LENGTH_SHORT).show();
                    }
                } else {
                    hideProgressDialog();
                }

            }

            @Override
            public void onFailure(@NonNull Call<UploadImageRespose> call, @NonNull Throwable t) {
                Timber.d(TAG, t.getMessage());
                hideProgressDialog();
                Toast.makeText(Activity.this, "Some Error  occurred, try again", Toast.LENGTH_SHORT).show();
            }
        });
    }

private void uploadToServer（字符串文件路径）{
showProgressDialog（）；
Refundation-Refundation=RefundationClient.getRefundationClient（此）；
ApiInterface UploadAPI=reformation.create（ApiInterface.class）；
文件文件=新文件（文件路径）；
//compressor.setDestinationDirectoryPath（）文件
RequestBody fileReqBody=RequestBody.create（MediaType.parse（“image/*”），文件）；
MultipartBody.Part部分=MultipartBody.Part.createFormData（“fileUpload”，file.getName（），fileReqBody）；
//RequestBody description=RequestBody.create（MediaType.parse（“text/plain”），“image type”）；
RequestBody imgNameReqBody=RequestBody.create（MediaType.parse（“多部分/表单数据”），“B2B_”+System.nanoTime（））；
uploadAPI.uploadImage（imgNameReqBody，part）.enqueue（新回调（）{
@凌驾
public void onResponse（@NonNull Call Call，@NonNull.2.Response-Response）{
if（response.issusccessful（）&&response.body（）！=null）{
if（response.body（）.getCODE（）.equalsIgnoreCase（“成功”））{
Toast.makeText（Activity.this，“成功上传配置文件图像”，Toast.LENGTH_SHORT.show（）；
}否则{
hideProgressDialog（）；
Toast.makeText（Activity.this，“发生了一些错误，请重试”，Toast.LENGTH_SHORT.show（）；
}
}否则{
hideProgressDialog（）；
}
}
@凌驾
public void onFailure（@NonNull Call Call，@NonNull Throwable t）{
Timber.d（TAG，t.getMessage（））；
hideProgressDialog（）；
Toast.makeText（Activity.this，“发生了一些错误，请重试”，Toast.LENGTH_SHORT.show（）；
}
});
}

在界面中添加以下方法：-

    @Multipart
    @POST("Your Path Here")
    Call<UploadImageRespose> uploadImage(@Part("img_name") RequestBody img_name,
                                         @Part MultipartBody.Part file);

@Multipart
@张贴（“您的路径在此”）
调用uploadImage（@Part（“img_name”）请求体img_name，
@Part MultipartBody.Part文件）；
让你检查这个&&@NileshRathod是的，我已经检查过了。多部分工作正常，但我在图像数组中保留了它们的数据。这应该足够了<代码>多部件主体。部件

加载到多个图像的循环中。您可以将格式数据放在同一个循环中并递增键。@Deˣ是的，我已经这样做了，但我有类型为的ArrayList和@Farhana，我已经用一种简单的方法更新了答案。显示异常

java.lang.IllegalArgumentException:@PartMap值不能是MultipartBody.Part。改为使用@Part List或其他值类型

我已经这样做了，请参见与您编辑的代码完全相同的内容，但我不清楚ApiInterface中要发送的参数。数据将以[0[]，1[]，2[]的形式发送。对于编辑的零件，与您现在拥有的相同。@Farhana检查更新的代码，您可以通过这种方式轻松实现它。

  private void uploadToServer(String filePath) {

        RequestBody imgNameReqBody = RequestBody.create(MediaType.parse("multipart/form-data"), "B2B_" + System.nanoTime());

        uploadAPIs.uploadImage(imgNameReqBody, part).enqueue(new Callback<UploadImageRespose>() {
            @Override
            public void onResponse(@NonNull Call<UploadImageRespose> call, @NonNull retrofit2.Response<UploadImageRespose> response) {
