Question

curl https://view-api.box.com/1/documents \
-H "Authorization: Token YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"url": "https://cloud.box.com/shared/static/4qhegqxubg8ox0uj5ys8.pdf"}' \
-X POST

你如何容纳网址？这是我到目前为止所尝试的内容。

final String url = "https://view-api.box.com/1/documents";

        @SuppressWarnings("resource")
        final HttpClient client = HttpClientBuilder.create().build();
        final HttpPost post = new HttpPost(url);

        post.setHeader("Authorization", "Token: TOKEN_ID");
        post.setHeader("Content-Type", "application/json");

        final List<NameValuePair> urlParameters = new ArrayList<NameValuePair>();
        urlParameters.add(new BasicNameValuePair("url", "https://cloud.box.com/shared/static/4qhegqxubg8ox0uj5ys8.pdf"));

        post.setEntity(new UrlEncodedFormEntity(urlParameters));

        final HttpResponse response = client.execute(post);
        System.out.println("Response Code : " + response.getStatusLine().getStatusCode());

        final BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));

        final StringBuffer result = new StringBuffer();
        String line = "";
        while ((line = rd.readLine()) != null) {
            result.append(line);
        }

    }

除了实体之外，你有一切正常，你在curl发送的内容不是html表单的内容，而是json对象。

首先取消这一部分（不要将数据发送为application / x-www-form-urlencoded）：

// comment out / delete  this from your code:
final List<NameValuePair> urlParameters = new ArrayList<NameValuePair>();
urlParameters.add(new BasicNameValuePair("url", "https://cloud.box.com/shared/static/4qhegqxubg8ox0uj5ys8.pdf"));

post.setEntity(new UrlEncodedFormEntity(urlParameters));

然后以这种方式添加身体：

BasicHttpEntity entity = new BasicHttpEntity();
InputStream body = new ByteArrayInputStream(
    "{\"url\": \"https://cloud.box.com/shared/static/4qhegqxubg8ox0uj5ys8.pdf\"}".getBytes());
entity.setContent(body);
post.setEntity(entity);

我假设您的JSON字符串只有0x20和0x7F之间的字符，但如果您使用其他字符（如Ñ），则需要使用编码UTF-8（使用的标准编码）将数据转换为字节数组在JSON数据中）以这种方式：

BasicHttpEntity entity = new BasicHttpEntity();
String myData = "{\"url\": \"https://cloud.box.com/shared/static/4qhegqxubg8ox0uj5ys8.pdf\"}";
ByteArrayOutputStream rawBytes = new ByteArrayOutputStream();
OutputStreamWriter writer = new OutputStreamWriter(rawBytes,
        Charset.forName("UTF-8"));
writer.append(myData);
InputStream body = new ByteArrayInputStream(rawBytes.toByteArray());
entity.setContent(body);
post.setEntity(entity);

我建议如下 - 虽然我不记得StringEntity是否在HTTPClient下可用

    final String url = "https://view-api.box.com/1/documents";

    @SuppressWarnings("resource")
    final HttpClient client = HttpClientBuilder.create().build();
    final HttpPost post = new HttpPost(url);

    post.setHeader("Authorization", "Token: TOKEN_ID");
    post.setHeader("Content-Type", "application/json");

    post.setEntity(new StringEntity("{\"url\": \"https://cloud.box.com/shared/static/4qhegqxubg8ox0uj5ys8.pdf\"}"));

    final HttpResponse response = client.execute(post);
    System.out.println("Response Code : " + response.getStatusLine().getStatusCode());

    final BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));

    final StringBuffer result = new StringBuffer();
    String line = "";
    while ((line = rd.readLine()) != null) {
        result.append(line);
    }

}
