将 postman form-data post 请求转换为 java 请求
Convert a postman form-data post request to a java request
我想将 postman 中的以下表单数据请求“转换”为 java 代码（在 java 调用者中）。更准确地说，我正在尝试实现下面显示的 api 的调用者，以便我可以通过 jar 访问端点。问题是我有 2 个字符串数组 to 和 cc 以及 2 个字符串 content 和subject（显然 api 发送电子邮件/暂时忽略附件字段）我不知道如何将这些参数设置为 [=36] 中的表单数据=].
这里是我在 Main post 中的方法 class
public static void myPostRequest() throws IOException {
URL object = new URL(POST_ENDPOINT);
HttpURLConnection postConnection = (HttpURLConnection) object.openConnection();
postConnection.setRequestMethod("POST");
postConnection.setRequestProperty("to", "alice@example.com");
postConnection.setRequestProperty("to", "bob@anotherex.com");
postConnection.setRequestProperty("cc", "alice@example.com");
postConnection.setRequestProperty("cc", "bob@anotherex.com");
postConnection.setRequestProperty("subject", "randomsubject");
postConnection.setRequestProperty("content", "randomContent");
// postConnection.setRequestProperty("contentType", "text/html");
// postConnection.setRequestProperty("Content-Type", "application/json");
postConnection.setDoOutput(true);
OutputStream os = postConnection.getOutputStream();
os.flush();
os.close();
int responseCode = postConnection.getResponseCode();
System.out.println("POST response code " + responseCode);
System.out.println("POST response message" + postConnection.getResponseMessage());
if (responseCode == HttpURLConnection.HTTP_OK) { //success
BufferedReader in = new BufferedReader(new InputStreamReader(postConnection.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
System.out.println("RESPONSE: " + response.toString());
} else {
System.out.println("POST DIDN`T WORK");
}
}
以及其他应用程序中的控制器方法（在 postman 中有效）：
@ApiOperation("Send notification email")
@RequestMapping(path = "/email", method = RequestMethod.POST, consumes = {"multipart/form-data"})
private String sendNotificationEmail(@RequestParam("to") String[] to,
@RequestParam("cc") String[] cc,
@RequestParam("subject") String subject,
@RequestParam("content") String content) String contentType,
@RequestParam(name = "attachments") MultipartFile[] attachements
) {
EmailSender.sendMail(new EmailSettings(to, cc, subject, content, null), attachements);
return "Email sent";
}

如果您正在使用 spring，正如我在 RequestMapping 注释中看到的那样，您为什么不使用 restTemplate 或 webclient？ （取决于您使用的 spring 版本）。会容易很多。
Spring 4 及以下的 Rest 模板，命令式
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
MultiValueMap<String, String> map= new LinkedMultiValueMap<>();
map.add("to", "alice@example.com");
map.add("to", "bob@anotherex.com");
map.add("cc", "alice@example.com");
map.add("cc", "bob@anotherex.com");
map.add("subject", "randomsubject");
map.add("content", "randomContent");
HttpEntity<MultiValueMap<String, String>> request = new HttpEntity<MultiValueMap<String, String>>(map, headers);
RestTemplate restTemplate= new RestTemplateBuilder().rootUri("http://localhost:8080").build();
restTemplate.postForLocation( "url", request);
WebClient for Spring 5+，反应式需要 WebFlux
WebClient client = WebClient.builder()
.baseUrl("http://localhost:8080")
.defaultHeader(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_FORM_URLENCODED_VALUE)
.build();
client.post()
.uri("/api/notification/email...")
.body(BodyInserters.fromFormData("to", "alice@example.com")
.with("to", "bob@anotherex.com")
.with("cc", "alice@example.com")
.with("cc", "bob@anotherex.com")
.with("subject", "randomsubject")
.with("content", "randomContent"))
.retrieve()
.toBodilessEntity()
.block();
在这两种情况下都在内部使用多值映射，因此您可以使用相同的键添加各种值，例如 to 和 cc
Postman 允许将请求转换为其他语言，只需单击请求下方的代码 link url。
我想将 postman 中的以下表单数据请求“转换”为 java 代码（在 java 调用者中）。更准确地说，我正在尝试实现下面显示的 api 的调用者，以便我可以通过 jar 访问端点。问题是我有 2 个字符串数组 to 和 cc 以及 2 个字符串 content 和subject（显然 api 发送电子邮件/暂时忽略附件字段）我不知道如何将这些参数设置为 [=36] 中的表单数据=].
这里是我在 Main post 中的方法 class
public static void myPostRequest() throws IOException {
URL object = new URL(POST_ENDPOINT);
HttpURLConnection postConnection = (HttpURLConnection) object.openConnection();
postConnection.setRequestMethod("POST");
postConnection.setRequestProperty("to", "alice@example.com");
postConnection.setRequestProperty("to", "bob@anotherex.com");
postConnection.setRequestProperty("cc", "alice@example.com");
postConnection.setRequestProperty("cc", "bob@anotherex.com");
postConnection.setRequestProperty("subject", "randomsubject");
postConnection.setRequestProperty("content", "randomContent");
// postConnection.setRequestProperty("contentType", "text/html");
// postConnection.setRequestProperty("Content-Type", "application/json");
postConnection.setDoOutput(true);
OutputStream os = postConnection.getOutputStream();
os.flush();
os.close();
int responseCode = postConnection.getResponseCode();
System.out.println("POST response code " + responseCode);
System.out.println("POST response message" + postConnection.getResponseMessage());
if (responseCode == HttpURLConnection.HTTP_OK) { //success
BufferedReader in = new BufferedReader(new InputStreamReader(postConnection.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
System.out.println("RESPONSE: " + response.toString());
} else {
System.out.println("POST DIDN`T WORK");
}
}
以及其他应用程序中的控制器方法（在 postman 中有效）：
@ApiOperation("Send notification email")
@RequestMapping(path = "/email", method = RequestMethod.POST, consumes = {"multipart/form-data"})
private String sendNotificationEmail(@RequestParam("to") String[] to,
@RequestParam("cc") String[] cc,
@RequestParam("subject") String subject,
@RequestParam("content") String content) String contentType,
@RequestParam(name = "attachments") MultipartFile[] attachements
) {
EmailSender.sendMail(new EmailSettings(to, cc, subject, content, null), attachements);
return "Email sent";
}

如果您正在使用 spring，正如我在 RequestMapping 注释中看到的那样，您为什么不使用 restTemplate 或 webclient？ （取决于您使用的 spring 版本）。会容易很多。
Spring 4 及以下的 Rest 模板，命令式
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
MultiValueMap<String, String> map= new LinkedMultiValueMap<>();
map.add("to", "alice@example.com");
map.add("to", "bob@anotherex.com");
map.add("cc", "alice@example.com");
map.add("cc", "bob@anotherex.com");
map.add("subject", "randomsubject");
map.add("content", "randomContent");
HttpEntity<MultiValueMap<String, String>> request = new HttpEntity<MultiValueMap<String, String>>(map, headers);
RestTemplate restTemplate= new RestTemplateBuilder().rootUri("http://localhost:8080").build();
restTemplate.postForLocation( "url", request);
WebClient for Spring 5+，反应式需要 WebFlux
WebClient client = WebClient.builder()
.baseUrl("http://localhost:8080")
.defaultHeader(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_FORM_URLENCODED_VALUE)
.build();
client.post()
.uri("/api/notification/email...")
.body(BodyInserters.fromFormData("to", "alice@example.com")
.with("to", "bob@anotherex.com")
.with("cc", "alice@example.com")
.with("cc", "bob@anotherex.com")
.with("subject", "randomsubject")
.with("content", "randomContent"))
.retrieve()
.toBodilessEntity()
.block();
在这两种情况下都在内部使用多值映射，因此您可以使用相同的键添加各种值，例如 to 和 cc
Postman 允许将请求转换为其他语言，只需单击请求下方的代码 link url。
