我正在使用Retrofit将图像上传到我的服务器.在这里,我需要为单个密钥上传多个图像.我已经尝试使用Postman Web客户端,它运行良好.这是截图
以下是请求的键值对.
SurveyImage:[file1,file2,file3];
PropertyImage:文件
DRA:jsonBody
我试图用Retrofit做同样的事情.但图像没有上传到服务器.这是我的代码.
WebServicesAPI.java
public interface WebServicesAPI {
@Multipart
@POST(WebServices.UPLOAD_SURVEY)
Call<UploadSurveyResponseModel> uploadSurvey(@Part MultipartBody.Part surveyImage, @Part MultipartBody.Part propertyImage, @Part("DRA") RequestBody dra);
}
这是上传文件的方法.
private void requestUploadSurvey() {
File propertyImageFile = new File(surveyModel.getPropertyImagePath());
RequestBody propertyImage = RequestBody.create(MediaType.parse("image/*"), propertyImageFile);
MultipartBody.Part propertyImagePart = MultipartBody.Part.createFormData("PropertyImage", propertyImageFile.getName(), propertyImage);
JSONObject requestBody = getRequestBody();
RequestBody draBody = null;
try {
draBody = RequestBody.create(MediaType.parse("text/plain"), requestBody.toString(1));
Log.d(TAG, "requestUploadSurvey: RequestBody : " + requestBody.toString(1));
} catch (JSONException e) {
e.printStackTrace();
}
MultipartBody.Builder builder = new MultipartBody.Builder();
builder.setType(MultipartBody.FORM);
MultipartBody surveyImage = null;
for (SurveyModel.PictureModel model : surveyModel.getPicturesList()) {
File file = new File(model.getImagePath());
builder.addFormDataPart("SurveyImage", file.getName(),
RequestBody.create(MediaType.parse("image/*"), file));
}
surveyImage = builder.build();
final WebServicesAPI webServicesAPI = RetrofitManager.getInstance().getRetrofit().create(WebServicesAPI.class);
Call<UploadSurveyResponseModel> surveyResponse = null;
surveyResponse = webServicesAPI.uploadSurvey(MultipartBody.Part.createFormData("SurveyImage", "SurveyImage", surveyImage), propertyImagePart, draBody);
surveyResponse.enqueue(this);
Log.d(TAG, "requestUploadSurvey: sent the request");
}
请帮我解决一下这个.
解决方法:
我们可以使用MultipartBody.Part数组将图像数组上传到单个键.
这是解决方案
WebServicesAPI
public interface WebServicesAPI {
@Multipart
@POST(WebServices.UPLOAD_SURVEY)
Call<UploadSurveyResponseModel> uploadSurvey(@Part MultipartBody.Part[] surveyImage, @Part MultipartBody.Part propertyImage, @Part("DRA") RequestBody dra);
}
这是上传文件的方法.
private void requestUploadSurvey() {
File propertyImageFile = new File(surveyModel.getPropertyImagePath());
RequestBody propertyImage = RequestBody.create(MediaType.parse("image/*"), propertyImageFile);
MultipartBody.Part propertyImagePart = MultipartBody.Part.createFormData("PropertyImage", propertyImageFile.getName(), propertyImage);
MultipartBody.Part[] surveyImagesParts = new MultipartBody.Part[surveyModel.getPicturesList().size()];
for (int index = 0; index < surveyModel.getPicturesList().size(); index++) {
Log.d(TAG, "requestUploadSurvey: survey image " + index + " " + surveyModel.getPicturesList().get(index).getImagePath());
File file = new File(surveyModel.getPicturesList().get(index).getImagePath());
RequestBody surveyBody = RequestBody.create(MediaType.parse("image/*"), file);
surveyImagesParts[index] = MultipartBody.Part.createFormData("SurveyImage", file.getName(), surveyBody);
}
final WebServicesAPI webServicesAPI = RetrofitManager.getInstance().getRetrofit().create(WebServicesAPI.class);
Call<UploadSurveyResponseModel> surveyResponse = null;
if (surveyImagesParts != null) {
surveyResponse = webServicesAPI.uploadSurvey(surveyImagesParts, propertyImagePart, draBody);
}
surveyResponse.enqueue(this);
}
