我想要一些帮助在Java中编写等效于下面的curl命令的内容。
curl -X POST --header 'Content-Type: application/json' --header 'Accept: application/json' --header 'cookie: [APP COOKIES];' -d 'sampleFile.json' 'https://url.com'
最佳答案
使用HttpClient的apache可以做到:
...
import org.apache.http.client.methods.HttpPost;
import org.apache.http.NameValuePair;
import org.apache.http.client.entity.UrlEncodedFormEntity
import org.apache.http.Consts;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.HttpEntity;
....
public String sendPost(String url, Map<String, String> postParams,
Map<String, String> header, String cookies) {
HttpPost httpPost = new HttpPost(url);
List<NameValuePair> formParams = new ArrayList<NameValuePair>();
HttpClientBuilder clientBuilder = HttpClients.createDefault();
CloseableHttpClient httpclient = clientBuilder.build();
if (header != null) {
Iterator<Entry<String, String>> itCabecera = header.entrySet().iterator();
while (itCabecera.hasNext()) {
Entry<String, String> entry = itCabecera.next();
httpPost.addHeader(entry.getKey(), entry.getValue());
}
}
httpPost.setHeader("Cookie", cookies);
if (postParams != null) {
Iterator<Entry<String, String>> itParms = postParams.entrySet().iterator();
while (itParms.hasNext()) {
Entry<String, String> entry = itParms.next();
formParams.add(new BasicNameValuePair(entry.getKey(), entry.getValue()));
}
}
UrlEncodedFormEntity formEntity = new UrlEncodedFormEntity(formParams, Consts.UTF_8);
httpPost.setEntity(formEntity);
CloseableHttpResponse httpResponse = httpclient.execute(httpPost);
HttpEntity entity = httpResponse.getEntity();
if (entity != null) {
pageContent = EntityUtils.toString(entity);
}
return pageContent;
}
希望对您有所帮助。
编辑:
我添加了发送文件的方式。我单独输入了一个代码,以免混淆代码(它是基于this examples的近似值):
File file = new File("path/to/file");
String message = "This is a multipart post";
MultipartEntityBuilder builder = MultipartEntityBuilder.create();
builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
if (postParams != null) {
Iterator<Entry<String, String>> itParms = postParams.entrySet().iterator();
while (itParms.hasNext()) {
Entry<String, String> entry = itParms.next();
builder.addTextBody(entry.getKey(), entry.getValue(), ContentType.DEFAULT_BINARY);
}
}
builder.addTextBody("text", message, ContentType.DEFAULT_BINARY);
HttpEntity entity = builder.build();
httpPost.setEntity(entity);
