我正在尝试使用从服务器端(在python中编码)应用程序生成的签名URL将视频文件从Android应用程序上传到S3服务器中的Bucket.我们正在向签名的URL发出PUT请求但我们正在收到
connection reset by peer exception
.
但是当我在POSTMAN REST CLIENT上尝试相同的URL时,会获得成功消息.
任何帮助将不胜感激.
解决方法:
使用Retrofit HTTP客户端库完成此操作,它成功将文件上传到Amazon s3服务器.
码:
public interface UploadService {
String BASE_URL = "https://bucket.s3.amazonaws.com/folder";
/**
* @param url :signed s3 url string after 'BASE_URL'.
* @param file :file to upload,( usage: new TypedFile("mp4", videoFile);.
* @param cb :callback.
*/
@PUT("/{url}")
void uploadFile(@Path(value = "url", encode=false) String url, @Body() TypedFile file, Callback<String> cb);
}
服务类
public final class ServiceGenerator {
private ServiceGenerator() {
}
public static <S> S createService(Class<S> serviceClass, String baseUrl) {
return createService(serviceClass, baseUrl, null, null);
}
public static <S> S createService(Class<S> serviceClass, String baseUrl, final String accesstoken, final String tokenType) {
class MyErrorHandler implements ErrorHandler {
@Override public Throwable handleError(RetrofitError cause) {
return cause;
}
}
Gson gson = new GsonBuilder()
.setFieldNamingPolicy(FieldNamingPolicy.LOWER_CASE_WITH_UNDERscoreS)
.registerTypeAdapter(Date.class, new DateTypeAdapter())
.disableHtmlEscaping()
.create();
RestAdapter.Builder builder = new RestAdapter.Builder()
.setEndpoint(baseUrl)
.setClient(new OkClient(new OkHttpClient()))
.setErrorHandler(new MyErrorHandler())
.setLogLevel(RestAdapter.LogLevel.FULL)
.setConverter(new GsonConverter(gson));
if (accesstoken != null) {
builder.setRequestInterceptor(new RequestInterceptor() {
@Override
public void intercept(RequestFacade request) {
request.addHeader("Accept", "application/json;versions=1");
request.addHeader("Authorization", tokenType +
" " + accesstoken);
}
});
}
RestAdapter adapter = builder.build();
return adapter.create(serviceClass);
}
并使用:
UploadService uploadService = ServiceGenerator.createService(UploadService.class,UploadService.BASE_URL);
uploadService.uploadFile(remUrl,typedFile,new CallbackInstance());
