在Spring Rest中使用JSON的HTTP POST

Question

我想用Spring RestTemplate做一個簡單的HTTP POST。 的WESB服務接受JSON的參數，例如：{"name":"mame","email":"email@gmail.com"}

public static void main(String[] args) { 

    final String uri = "url"; 
    RestTemplate restTemplate = new RestTemplate(); 
    // Add the Jackson message converter 
    restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter()); 
    // create request body 
    String input = "{ \"name\": \"name\", \"email\": \"email@gmail.com\" }"; 
    JsonObject request = new JsonObject(); 
    request.addProperty("model", input); 

    // set headers 
    HttpHeaders headers = new HttpHeaders(); 
    headers.setContentType(MediaType.APPLICATION_JSON); 
    headers.set("Authorization", "Basic " + "xxxxxxxxxxxx"); 
    HttpEntity<String> entity = new HttpEntity<String>(request.toString(), headers); 

    // send request and parse result 
    ResponseEntity<String> response = restTemplate 
      .exchange(uri, HttpMethod.POST, entity, String.class); 

    System.out.println(response); 
} 

當我測試這個代碼，我得到這個錯誤：

Exception in thread "main" org.springframework.web.client.HttpClientErrorException: 400 Bad Request 

當我打電話web服務與捲曲我有正確的結果：

curl -X POST -H "Authorization: Basic xxxxxxxxxx" --header "Content-Type: application/json" --header "Accept: application/json" -d "{ \"name\": \"name\", \"email\": \"email@gmail.com\" } " "url"

嘗試從代碼中刪除model，因爲我可以在您的捲髮請求中看到您沒有使用模型屬性，並且一切正常。試試這個：

public static void main(String[] args) { 

    final String uri = "url"; 
    RestTemplate restTemplate = new RestTemplate(); 
    // Add the Jackson message converter 
    restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter()); 
    // create request body 
    String input = "{\"name\":\"name\",\"email\":\"email@gmail.com\"}"; 


    // set headers 
    HttpHeaders headers = new HttpHeaders(); 
    headers.setContentType(MediaType.APPLICATION_JSON); 
    headers.set("Authorization", "Basic " + "xxxxxxxxxxxx"); 
    HttpEntity<String> entity = new HttpEntity<String>(input, headers); 

    // send request and parse result 
    ResponseEntity<String> response = restTemplate 
      .exchange(uri, HttpMethod.POST, entity, String.class); 

    System.out.println(response); 
}
