从Java代码解析cURL命令导致错误[关闭]答案

【问题描述】：

我正在尝试解析一些 cURL 命令：

curl -X POST \
-H "Content-Type: application/json" \
-H "Accept: application/json" \
-H "Authorization: Token token_key" \
-d '{ "query": "query" }' \
https://suggestions.dadata.ru/suggestions/api/4_1/rs/findById/fias

但我的版本：

ProcessBuilder pb = new ProcessBuilder(
                "curl",
                "-X", "\"POST\"",
                "-H", "\"Content-Type: application/json\"",
                "-H", "\"Accept: application/json\"",
                "-H", "\"Authorization: Token token\"",
                "-d", "\"{ \"query\": \"query\" }\"",
                "https://suggestions.dadata.ru/suggestions/api/4_1/rs/findById/fias");

抛出错误：

{"family":"CLIENT_ERROR","reason":"Bad Request","message":"Unexpected character ('q' (code 113)):
was expecting double-quote to start field name\n at [Source: (org.apache.cxf.transport.http.AbstractHTTPDestination$1);

有人可以帮忙吗？感谢您的帮助

【问题讨论】：

不要引用参数，ProcessBuilder 会根据需要这样做。例如。使用 "-X", "POST", 而不使用任何 \"。当然，您仍然必须引用 JSON 名称和字符串值。
@Andreas 谢谢，但这并没有帮助。我现在通过 HttpURLConnection 连接，它可以工作了

标签： java curl

【解决方案1】：

也许对某人有帮助

String request = "https://suggestions.dadata.ru/suggestions/api/4_1/rs/findById/fias"

URL url = new URL(request);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setDoOutput(true);
conn.setInstanceFollowRedirects(false);
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type", "application/json");
conn.setRequestProperty("Accept", "application/json");
conn.setRequestProperty("Authorization", "Token token");
JSONObject query = new JSONObject();
query.put("query", "query");

OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
wr.write(query.toString());
wr.flush();

InputStream inputStream = conn.getInputStream();
