我添加了与条带服务器指南有关的所有内容，但不适用于
我这是我的代码，我没有添加条纹键，也请指导我
我在其中添加条带键，但仍在body.please中返回null
如果您有任何想法，请指导我。
try {
HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient client = new OkHttpClient.Builder().addInterceptor(interceptor).build();
// Change base URL to your upload server URL.
service = new Retrofit.Builder().baseUrl("https://uploads.stripe.com/v1/files/").client(client).build().create(InterfaceService.class);
} catch (Exception e) {
e.printStackTrace();
}
// File file = new File(filePath);
RequestBody reqFile = RequestBody.create(MediaType.parse("image/*"), actualFile);
MultipartBody.Part body = MultipartBody.Part.createFormData("file", fileName, reqFile);
RequestBody name = RequestBody.create(MediaType.parse("text/plain"), "upload_test");
// Log.d("THIS", data.getData().getPath());
Map<String, RequestBody> fileUploadParams = new HashMap<>();
fileUploadParams.put("purpose", InterfaceService.createRequestBody("identity_document"));
fileUploadParams.put("file", InterfaceService.createRequestBody(actualFile));
retrofit2.Call<ResponseBody> req = service.uploadFileWithPartMap(fileUploadParams, body);
req.enqueue(new Callback<ResponseBody>() {
@Override
public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
最佳答案
这是在条带上上传文件的完整解决方案
multipart = new MultipartUtility("https://uploads.stripe.com/v1/files", "");
// In your case you are not adding form data so ignore this
/*This is to add parameter values */
multipart.addFormField("purpose", "identity_document");
multipart.addFilePart("file", new File(frontPath));
response = multipart.finish();
这是实用程序类
