【问题描述】：

我得到了这个端点，但我不知道如何从手机图库中拍照并通过这个端点发送这个图像？

【问题讨论】：

查看本教程futurestud.io/tutorials/…，它可以帮助您使用 Retrofit 将文件发送到服务器
stackoverflow.com/questions/40008840/…

【解决方案1】：

试试这个代码..

将以下依赖添加到应用级 gradle 文件中..

   implementation 'com.squareup.okhttp3:logging-interceptor:3.4.1'
implementation 'com.squareup.retrofit2:retrofit:2.3.0'
implementation 'com.squareup.retrofit2:converter-gson:2.3.0'

然后定义改造对象..

public class ApiClient {
private final static String BASE_URL = "https://api.github.com";

public static ApiClient apiClient;
private Retrofit retrofit = null;

public static ApiClient getInstance() {
    if (apiClient == null) {
        apiClient = new ApiClient();
    }
    return apiClient;
}

//private static Retrofit storeRetrofit = null;

public Retrofit getClient() {
    return getClient(null);
}


private Retrofit getClient(final Context context) {

    HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
    interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
    OkHttpClient.Builder client = new OkHttpClient.Builder();
    client.readTimeout(60, TimeUnit.SECONDS);
    client.writeTimeout(60, TimeUnit.SECONDS);
    client.connectTimeout(60, TimeUnit.SECONDS);
    client.addInterceptor(interceptor);
    client.addInterceptor(new Interceptor() {
        @Override
        public okhttp3.Response intercept(Chain chain) throws IOException {
            Request request = chain.request();

            return chain.proceed(request);
        }
    });

    retrofit = new Retrofit.Builder()
            .baseUrl(BASE_URL)
            .client(client.build())
            .addConverterFactory(GsonConverterFactory.create())
            .build();


    return retrofit;
}
}

制作api接口..

public interface ApiInterface {
@Multipart
@POST("/signup/")
Call<UserResponseVo> registerUser(@PartMap Map<String, RequestBody> map);
}

和 api 调用到活动中..

 private void uploadImage() {
    ApiInterface apiInterface= ApiClient.getInstance().getClient().create(ApiInterface.class);
    file=new File(mAttachmentFilePath);
    RequestBody mFile = RequestBody.create(MediaType.parse("image/*"), file);
    MultipartBody.Part fileToUpload = MultipartBody.Part.createFormData("profile_pic", file.getName(), mFile);
    RequestBody userObjectId = RequestBody.create(MediaType.parse("text"), "HZucg1m6Gz");



    Call<UserProfileResponse> userProfileResponseCall=apiInterface.uploadImage(fileToUpload,userObjectId);
    showProgress();
    userProfileResponseCall.enqueue(new Callback<UserProfileResponse>() {
        @Override
        public void onResponse(Call<UserProfileResponse> call, Response<UserProfileResponse> response) {
            if (response!=null && response.body()!=null && response.isSuccessful()){
                closeProgress();
                Toast.makeText(getApplicationContext(),response.body().getMsg(),Toast.LENGTH_LONG).show();
                Log.d("Response Message::",response.body().getMsg());
                Glide.with(MainActivity.this).load(response.body().getAvatarUrl()).into(mIvServerImage);
            }
        }

        @Override
        public void onFailure(Call<UserProfileResponse> call, Throwable t) {
            closeProgress();
            Log.d("Error::",t.getMessage());
        }
    });
}

我希望您知道如何打开图库并获取选定的图像路径。如果您在 marshallow 设备上运行应用程序，则添加权限模型。
