# AITranslateService API 文档
## 1. 功能介绍
AITranslateService 是一个AI翻译服务类，用于处理与AI翻译相关的服务调用，集成了豆包API，支持多种语言间的文本翻译。
## 2. 核心功能
- **文本翻译**：支持用户输入待翻译文本及选择源语言和目标语言
- **翻译缓存**：添加请求缓存机制，避免重复翻译相同内容
- **错误处理**：实现完善的错误处理机制，包括网络异常、API调用失败、参数错误等情况的处理
- **API连接测试**：提供API连接测试功能，确保接口调用稳定可靠
## 3. 类结构
```java
public class AITranslateService {
// 常量定义
private static final String TAG = "AITranslateService";
private static final String DOUBAO_API_URL = "https://ark.cn-beijing.volces.com/api/v3/responses";
private static final String API_KEY = "ee5fb4c7-ea14-4481-ac23-4b0e82907850";
// 翻译缓存
private static final Map<String, String> translationCache = new HashMap<>();
// 核心方法
public static void translateText(String text, String sourceLanguage, String targetLanguage, TranslateCallback callback)
public static void clearTranslationCache()
public static void testTranslateApiConnection(TranslateCallback callback)
// 回调接口
public interface TranslateCallback {
void onSuccess(String translatedText);
void onFailure(String errorMessage);
}
}
```
## 4. 核心方法说明
### 4.1 translateText
```java
public static void translateText(String text, String sourceLanguage, String targetLanguage, TranslateCallback callback)
```
**功能**：翻译指定文本从源语言到目标语言
**参数**：
- `text`：待翻译文本，不能为空
- `sourceLanguage`：源语言，如"英文"、"中文"等，不能为空
- `targetLanguage`：目标语言，如"中文"、"英文"等，不能为空
- `callback`：翻译结果回调接口
**返回值**：无，结果通过回调接口返回
**示例**：
```java
AITranslateService.translateText(
"Hello, world!",
"英文",
"中文",
new AITranslateService.TranslateCallback() {
@Override
public void onSuccess(String translatedText) {
Log.d("Translation", "翻译结果: " + translatedText);
// 处理翻译成功的结果
}
@Override
public void onFailure(String errorMessage) {
Log.e("Translation", "翻译失败: " + errorMessage);
// 处理翻译失败的情况
}
}
);
```
### 4.2 clearTranslationCache
```java
public static void clearTranslationCache()
```
**功能**：清空翻译缓存，释放内存
**参数**：无
**返回值**：无
**示例**：
```java
AITranslateService.clearTranslationCache();
```
### 4.3 testTranslateApiConnection
```java
public static void testTranslateApiConnection(TranslateCallback callback)
```
**功能**：测试翻译API连接是否正常
**参数**：
- `callback`：测试结果回调接口
**返回值**：无，结果通过回调接口返回
**示例**：
```java
AITranslateService.testTranslateApiConnection(new AITranslateService.TranslateCallback() {
@Override
public void onSuccess(String result) {
Log.d("API Test", "API连接测试成功: " + result);
// 处理API连接测试成功的情况
}
@Override
public void onFailure(String errorMessage) {
Log.e("API Test", "API连接测试失败: " + errorMessage);
// 处理API连接测试失败的情况
}
});
```
## 5. 错误处理
AITranslateService 实现了完善的错误处理机制，包括以下情况：
1. **参数错误**：当文本、源语言或目标语言为空时，会返回相应的错误信息
2. **网络异常**：当网络连接失败或超时<E8B685><E697B6><EFBFBD>，会返回相应的错误信息
3. **API调用失败**：当API调用失败时，会返回API返回的错误信息
4. **JSON解析错误**：当解析API响应失败时，会返回相应的错误信息
5. **其他异常**：当发生其他异常时，会返回异常信息
## 6. 性能优化
AITranslateService 通过以下方式进行性能优化：
1. **翻译缓存**：使用 `HashMap` 存储翻译结果，避免重复翻译相同内容
2. **异步处理**：所有API调用都在子线程中执行，避免阻塞主线程
3. **超时设置**：设置了30秒的连接超时和读取超时，避免长时间等待
## 7. 使用建议
1. **语言选择**：源语言和目标语言建议使用中文名称，如"英文"、"中文"、"日语"等
2. **文本长度**：建议单次翻译的文本长度不要过长，以免超过API限制
3. **缓存管理**：在应用退出或内存不足时，建议调用 `clearTranslationCache()` 方法清空缓存
4. **错误处理**：使用时应妥善处理回调中的错误信息，提供友好的用户提示
5. **网络状态**：在调用翻译功能前，建议检查网络连接状态，确保网络可用
## 8. 依赖说明
AITranslateService 依赖以下库：
1. **Android SDK**：需要Android SDK 21及以上版本
2. **JSON库**：使用Android内置的org.json库
3. **网络权限**：需要在AndroidManifest.xml中添加网络权限
```xml
<uses-permission android:name="android.permission.INTERNET" />
```
## 9. 测试方法
### 9.1 单元测试
AITranslateService 提供了单元测试类 `AITranslateServiceTest`，包含以下测试方法：
- `testTranslateText`：测试翻译功能
- `testTranslationCache`：测试缓存功能
- `testClearTranslationCache`：测试清空缓存功能
- `testParameterErrorHandling`：测试参数错误处理
- `testTranslateApiConnection`：测试API连接
### 9.2 集成测试
集成测试建议在实际设备或模拟器上进行，测试步骤如下：
1. 确保设备已连接网络
2. 调用 `testTranslateApiConnection` 方法测试API连接
3. 调用 `translateText` 方法测试翻译功能，使用不同的文本和语言组合
4. 测试缓存功能，对相同内容进行多次翻译
5. 测试错误处理，传入空参数或模拟网络异常
## 10. 代码示例
### 10.1 基本使用示例
```java
// 1. 测试API连接
AITranslateService.testTranslateApiConnection(new AITranslateService.TranslateCallback() {
@Override
public void onSuccess(String result) {
Log.d("API Test", "API连接测试成功: " + result);
// API连接正常，可以进行翻译
}
@Override
public void onFailure(String errorMessage) {
Log.e("API Test", "API连接测试失败: " + errorMessage);
// API连接失败，需要检查网络或API配置
}
});
// 2. 执行翻译
AITranslateService.translateText(
"这是一段测试文本",
"中文",
"英文",
new AITranslateService.TranslateCallback() {
@Override
public void onSuccess(String translatedText) {
Log.d("Translation", "翻译结果: " + translatedText);
// 显示翻译结果
}
@Override
public void onFailure(String errorMessage) {
Log.e("Translation", "翻译失败: " + errorMessage);
// 显示错误信息
}
}
);
// 3. 清空缓存（在适当的时候）
AITranslateService.clearTranslationCache();
```
### 10.2 完整的Activity示例
```java
public class TranslateActivity extends AppCompatActivity {
private EditText etSourceText;
private Spinner spSourceLanguage;
private Spinner spTargetLanguage;
private Button btnTranslate;
private TextView tvResult;
private ProgressBar pbLoading;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_translate);
initViews();
setupListeners();
}
private void initViews() {
etSourceText = findViewById(R.id.et_source_text);
spSourceLanguage = findViewById(R.id.sp_source_language);
spTargetLanguage = findViewById(R.id.sp_target_language);
btnTranslate = findViewById(R.id.btn_translate);
tvResult = findViewById(R.id.tv_result);
pbLoading = findViewById(R.id.pb_loading);
// 初始化语言选择器
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this,
R.array.languages_array, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spSourceLanguage.setAdapter(adapter);
spTargetLanguage.setAdapter(adapter);
// 默认选择：英文 -> 中文
spSourceLanguage.setSelection(0);
spTargetLanguage.setSelection(1);
}
private void setupListeners() {
btnTranslate.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String text = etSourceText.getText().toString().trim();
if (text.isEmpty()) {
Toast.makeText(TranslateActivity.this, "请输入待翻译文本", Toast.LENGTH_SHORT).show();
return;
}
String sourceLanguage = spSourceLanguage.getSelectedItem().toString();
String targetLanguage = spTargetLanguage.getSelectedItem().toString();
pbLoading.setVisibility(View.VISIBLE);
tvResult.setText("");
AITranslateService.translateText(text, sourceLanguage, targetLanguage, new AITranslateService.TranslateCallback() {
@Override
public void onSuccess(final String translatedText) {
runOnUiThread(new Runnable() {
@Override
public void run() {
pbLoading.setVisibility(View.GONE);
tvResult.setText(translatedText);
}
});
}
@Override
public void onFailure(final String errorMessage) {
runOnUiThread(new Runnable() {
@Override
public void run() {
pbLoading.setVisibility(View.GONE);
Toast.makeText(TranslateActivity.this, "翻译失败: " + errorMessage, Toast.LENGTH_SHORT).show();
}
});
}
});
}
});
}
}
```
## 11. 常见问题与解决方案
### 11.1 API调用失败
**症状**：调用翻译功能时返回"API error: xxx"错误
**可能原因**：
- API_KEY 无效或过期
- 网络连接不稳定
- API服务暂时不可用
**解决方案**：
- 检查API_KEY是否正确
- 检查网络连接状态
- 稍后重试或联系API提供商
### 11.2 翻译结果为空
**症状**：翻译成功但返回空字符串
**可能原因**：
- 待翻译文本为空
- API返回格式发生变化
**解决方案**：
- 确保待翻译文本不为空
- 检查API响应格式是否与代码解析逻辑匹配
### 11.3 缓存不生效
**症状**：重复翻译相同内容时，每次都调用API
**可能原因**：
- 缓存键生成逻辑有误
- 缓存被意外清空
**解决方案**：
- 检查缓存键的生成逻辑
- 确保没有在不适当的时候调用 `clearTranslationCache()`
### 11.4 网络超时
**症状**：翻译过程中返回"Socket timeout error"错误
**可能原因**：
- 网络连接速度慢
- API响应时间过长
**解决方案**：
- 检查网络连接状态
- 尝试使用更快的网络
- 考虑调整超时设置（在 `sendPostRequest` 方法中）
