使用 okhttp 3.9.0 将文件上传到 REST 给出错误代码 = 422，消息 = Uprocessable 实体

Question

我正在尝试通过 okhttp3 (3.9.0) 将文件上传到 REST 服务。

它不起作用，我收到错误：**代码=422，消息=不可处理的实体** 但我找不到我的错误...

这是我的代码：

private void test_OK_HTTP() {

        String userCredentials = "username:password";
        String basicAuth = "Basic " + new String(Base64.getEncoder().encode(userCredentials.getBytes()));

        File f = new File("C:\history48.png");
       
      
        OkHttpClient client = new OkHttpClient();

        RequestBody requestBody = new MultipartBody.Builder()
                .setType(MultipartBody.FORM)
                .addFormDataPart("DocumentName", "file.png")
                .addFormDataPart("FK_Person", "1d64b9cc-d405-47c4-9adb-ef276c391ae0&")
                .addFormDataPart("FK_FileManagerFormKey", "33")
                .addFormDataPart("SystemFileType", "368")
                .addFormDataPart("Subject", "test")
                .addFormDataPart("SubjectDate", "2022-02-24")
                .addFormDataPart("DocumentContent", "file.png", RequestBody.create(MediaType.parse("image/png"), f))                                    
                .build();

        Request request = new Request.Builder()
                .url("http://myurlthatworksfine/RestServiceTest/AddNewDocument")
                .addHeader("api-version", "v1")
                .addHeader("Authorization", basicAuth)
                .post(requestBody)            
                .build();
        
        System.out.println("Request: "+request.body().toString());

        try {
            Response response = client.newCall(request).execute();
            System.out.println("Response: " + response.toString());

        } catch (Exception e) {
            e.printStackTrace();
            System.out.println("Error: "+e);
        }

    }

有人知道我做错了什么吗？

谢谢。

我的 test-id 中有一个简单的错误...现在可以使用...:)

错误： .addFormDataPart("FK_Person", "1d64b9cc-d405-47c4-9adb-ef276c391ae0&")

好的： .addFormDataPart("FK_Person", "1d64b9cc-d405-47c4-9adb-ef276c391ae0")

使用 okhttp 3.9.0 将文件上传到 REST 给出错误代码 = 422，消息 = Uprocessable 实体

Uploading File with okhttp 3.9.0 to REST is giving Error code=422, message=Uprocessable Entity
