Salesforce-API kann nicht mit Spring RestTemplate aufgerufen werden

Question

Ich entwickle eine Anwendung mit Java + Salesforce und Aufrufen von Salesforce-Diensten mit der Spring RestTemplate-API, scheint jedoch einen Fehler zu erhalten. Irgendeine Hilfe ?

Wenn ich Postbote überprüfte, funktioniert es gut.

https://ap5.salesforce.com/services/oauth2/token?client_id=XXXXXXXX&client_secret=XXXXXXXXXXX&username=XXXXXXXXXXXXX&password=XXXXXXXXXXXX&grant_type=password

Answer 1

gleich sein muss, diese umgesetzt werden, wie unter denen funktioniert.

// create the Map of the MultiValueMap 
MultiValueMap<String, String> map = new LinkedMultiValueMap<String, String>(); 
map.add("grant_type", "password"); 
map.add("client_id", "XX"); 
map.add("client_secret", "XXX"); 
map.add("username", "XX"); 
map.add("password", "XXX"); 

// RestTemplate 
RestTemplate restTemplate = new RestTemplate(); 
Map<String, String> token = restTemplate.postForObject(TOKEN_URL, map, Map.class); 
System.out.println("--------------------------------------------"); 
System.out.println("Access Token :: "+token.get("access_token")); 
System.out.println("Instance Url :: "+token.get("instance_url")); 
System.out.println("Id :: "+token.get("id")); 
System.out.println("Token_Type :: "+token.get("token_type")); 
System.out.println("Signature :: "+token.get("signature")); 
System.out.println("--------------------------------------------"); 

Die Token-URL wäre die unten. Hier

final static String TOKEN_URL = "https://login.salesforce.com/services/oauth2/token"; 

ist die Ausgabe als Referenz:

-------------------------------------------- 
Access Token :: 00D7F0000001I8v!ARgAQB7R8VtkU8QbUYHfdBjytHPATIDYmMKkPt7sunvUW4DeM2t.c.wFDJ0.k0uNPogX5aPWIrL_lHkrbfNai_t.byjjRCy_ 
Instance Url :: https://ap5.salesforce.com 
Id :: https://login.salesforce.com/id/00D7F0000001I8vUAE/0057F000000l2bgQAA 
Token_Type :: Bearer 
Signature :: veYhITIlhqf9SJqvBAZ4PKiLh1sj9at13D3m44TnBxw= 
-------------------------------------------- 

Answer 2

Sie versuchen, Ihre Abfrage-String-Parameter als Header zu senden (was nicht dasselbe ist). Der folgende Code wird auf Ihren Test in Postman

public class RestTemplateExample { 

    final static String TOKEN_URL = "https://ap5.salesforce.com/services/oauth2/token"; 

    public static void main(String[] args) { 

    UriComponentsBuilder builder = UriComponentsBuilder.fromHttpUrl(TOKEN_URL) 
     .queryParam("client_secret", "XXXXXXXXX") 
     .queryParam("client_id", "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX") 
     .queryParam("grant_type", "password") 
     .queryParam("username", "XXX@XX.com") 
     .queryParam("password", "XXXXXXXXXXXX"); 

     HttpHeaders headers = new HttpHeaders(); 
     headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON)); 

     HttpEntity<String> entity = new HttpEntity<String>("", headers); 

     RestTemplate restTemplate = new RestTemplate(); 
     ResponseEntity<String> result = restTemplate.exchange(
      builder.build().encode().toUri(), 
      HttpMethod.POST, 
      entity, String.class 
     ); 
     System.out.println("TOKEN DETAILS :: "+result.getBody()); 
    } 
}
