【问题描述】：

我正在尝试使用 post 方法注册用户，用户已注册但图像未上传且没有错误。

我看到了很多类似的问题，但没有得到解决方案。

从chrome扩展rest api请求和html表单上传成功的图片。

我的代码在下面...

@Multipart
@POST("webservicename")
Call<Login> userUpdate1(@Part("device_id") RequestBody deviceid,
                        @Part("ip_address") RequestBody ipaddress,

                        @Part("bdate") RequestBody bdate,
                        @Part("mangal_sani") RequestBody mangal_sani,
                        @Part("spect") RequestBody spect,
                        @Part("merried_status") RequestBody merried_status,

    final ProgressDialog pDialog = new ProgressDialog(getActivity());
    pDialog.setIndeterminate(true);

    pDialog.setCancelable(false);

        file = new File(selectedFilePath);
     else 
        file = new File(imagename);
    

    RequestBody reqFile = RequestBody.create(MediaType.parse("image/jpeg"), file);

【问题讨论】：

请使用 Logcat...除了改造之外，您是否尝试过任何其他库？

How to Upload Image file in Retrofit 2的可能重复

检查：***.com/questions/47290322/…

【参考方案1】：

在您的 Calling 类中创建 Multipart 主体，如下所示；

MultipartBody.Part body = MultipartBody.Part.createFormData("profile_images",file.getName(), RequestBody.create(MediaType.parse("image/*"),file));

这里 profile_images 是文件的参数名称

在您的界面中使用@Part MultipartBody.Part file 而不是@Part("profile_images") MultipartBody.Part profile_images，因此您的代码如下：-

@Multipart
@POST("webservicename")
Call<Login> userUpdate1(@Part("device_id") RequestBody deviceid,
                        @Part("ip_address") RequestBody ipaddress,
                        @Part("user_id") RequestBody userid,
                        @Part MultipartBody.Part profile_images ...)

我希望它对你有用。

【讨论】：

我的改造库版本是旧的所以它没有上传我编译新的改造库然后我得到解决方案..感谢您的回复。

@bhoomikapatel 问题不是库版本，根据您问题中的代码，问题出在您的界面中

但是我的旧库版本在@part 之后如果我更改库会给出错误传递值然后它不会在接口类中给出错误并且我没有传递值

【参考方案2】：

试试这个

在你的方法中

MultipartBody.Part filepart = MultipartBody.Part.createFormData("photo",file.getName(), RequestBody.create(MediaType.parse("image/*"),file));
Call<User> call = client.createAccount(filepart);

在您的 API 界面中

public interface UserClient 

    @Multipart
    @POST("apiupdateprofile.php")

    Call<User> createAccount(

            @Part MultipartBody.Part filepart

    );

【讨论】：

在@part之后的接口类中给出错误传递值complusry

如果我在 MultipartBody.Part 中的 @part 之后没有传递值，则添加缺少的注释参数值会给出错误

在你的图片部分试试我的代码。如果我的回答有用，请点击我的回答上的勾号。

【参考方案3】：

试试这个：

RequestBody reqFile = RequestBody.create(MediaType.parse("multipart/form-data"), file);

【参考方案4】：

如果你想上传图片，试试这个方法MediaType.parse("image/*")

MultipartBody.Part body = null;

            if (selectedImagePath != null) 
                File file = new File (selectedImagePath);
                RequestBody reqFile = RequestBody.create(MediaType.parse("image/*"), file);
                body = MultipartBody.Part.createFormData("keyWord", file.getName(), reqFile);
