通过curl测试谷歌翻译API

Question

我正在通过curl 测试Google Translate API，它不断询问参数q，而参数q 已经存在于URL 中（q=Hello%20World）。为什么 Google Translate API 返回此错误？

卷曲https://www.googleapis.com/language/translate/v2?key= &source=en&target=de&q=Hello%20World

[1] 16848
[2] 16849
[3] 16850
[2]-  Done                    source=en
[3]+  Done                    target=de
foo:~ foo$ {
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "required",
    "message": "Required parameter: q",
    "locationType": "parameter",
    "location": "q"
   },
   {
    "domain": "global",
    "reason": "required",
    "message": "Required parameter: target",
    "locationType": "parameter",
    "location": "target"
   }
  ],
  "code": 400,
  "message": "Required parameter: q"
 }
}

帮助？

您必须将整个 URL 用双引号引起来，如下所示：

curl "https://www.googleapis.com/language/translate/v2?key=&source=en&target=de&q=Hello%20World"

&否则，您的 shell 将在实际执行之前解释这些字符curl；这就是为什么你会在开头看到所有这些行：

[1] 16848
[2] 16849
[3] 16850
[2]-  Done                    source=en
[3]+  Done                    target=de
