Google Translate API:来自此客户端应用程序的请求< empty>被封锁 [英] Google Translate API: Requests from this client application <empty> are blocked

问题描述

我一直收到错误403-使用付费的Google Cloud Platform Translation API阻止了来自此Android客户端应用程序的请求.将限制设置为无时，效果很好.报告类似问题有一些线索，但没有一个答案.

I've been getting error 403 - Requests from this Android client application are blocked using paid Google Cloud Platform Translation API. Works great when restrictions are set to none. There are a few threads around reporting similar issue, but none answered.

我在某些示例中看到过，有一个具有.setApplicationName()的版本，我认为这可能会有所帮助，但是我找不到那个版本.

I've seen in some examples, there's a version which had .setApplicationName(), I think that might help, but I can't find which version would that be.

使用的代码是:`

private void translate(String textToTranslate, String targetLanguage, TranslateCallback callback) {
    try {
        TranslateOptions options = TranslateOptions.newBuilder()
                        .setApiKey( < api_key >)
                        .build();
        Translate trService = options.getService();
        Translation translation = trService.translate(textToTranslate,TranslateOption.targetLanguage(targetLanguage));
        callback.onSuccess(translation.getTranslatedText());
    }
    catch(Exception e) {
        callback.onFailure();
    }
}`

推荐答案

最后我找到了一种方法.

Finally I found a way.

在为Android应用设置API密钥限制时，您指定了程序包名称和SHA-1证书指纹.因此，当您向Google发送请求时，必须在每个请求的标题中添加这些信息.

When setting up your API key restriction for android app, you specified the package name and SHA-1 certificate fingerprint. So when you send an request to Google, you must add these information in the header of each request.

connection.setRequestProperty("X-Android-Package", "com.example.awesomeapp");
String sign = "5D:5A:12:D3:......".toLowerCase(); //Your SHA1 key in lower cased.
connection.setRequestProperty("X-Android-Cert", sig);
