[英]Salesforce REST API Login?
我正在检查 salesforce 开发人员站点中的一个示例。
在该示例中,当我们单击链接时,它将被重定向到 Salesforce 登录页面。 如果登录成功,则会发出访问令牌。
我不希望我的应用程序重定向到 Salesforce 登录页面。 在现有示例中,环境变量设置为,
“https://login.salesforce.com”
我应该怎么做才能避免重定向到 Salesforce 登录页面。
您所描述的内容听起来像 OAuth(只是因为您提到了访问令牌)。
下面是在 Salesforce 中使用 OAuth 的一个很好的例子......

解决方案:
大家好,我已经找到了解决我的问题的方法。 实际上,我正在检查链接http://wiki.developerforce.com/page/Getting_Started_with_the_Force.com_REST_API 中给出的示例。 然后实现了来自https://login.salesforce.com/help/doc/en/remoteaccess_oauth_username_password_flow.htm#send_up_response 的OAuth 2.0 用户名-密码流。 它解决了我的问题。
这是使用用户名-密码 OAuth 流程的示例 Java 代码:
public class AccountQuery
{
// The connection data
private static final String query = "SELECT Name, Idfrom Account";
private static final String clientId = "theID";
private static final String clientSecret = "theSecret";
// THis is meaningless in our context
private static final String redirectUri = "https://localhost:8443/_callback";
private static final String environment = "https://login.salesforce.com";
private static String tokenUrl = null;
private static final String username = "username";
private static final String password = "passwordPlusSecret";
private static String accessToken = null;
private static String instanceUrl = null;
public static void main( String[] args )
{
// Step 0: Connect to SalesForce.
System.out.println("Getting a token");
tokenUrl = environment + "/services/oauth2/token";
HttpClient httpclient = new HttpClient();
PostMethod post = new PostMethod(tokenUrl);
post.addParameter("grant_type", "password");
post.addParameter("client_id", clientId);
post.addParameter("client_secret", clientSecret);
post.addParameter("redirect_uri", redirectUri);
post.addParameter("username", username);
post.addParameter("password", password);
try {
httpclient.executeMethod(post);
try {
JSONObject authResponse = new JSONObject(new JSONTokener(new InputStreamReader(post.getResponseBodyAsStream())));
System.out.println("Auth response: " + authResponse.toString(2));
accessToken = authResponse.getString("access_token");
instanceUrl = authResponse.getString("instance_url");
System.out.println("Got access token: " + accessToken);
} catch (JSONException e) {
e.printStackTrace();
}
} catch (HttpException e1) {
e1.printStackTrace();
} catch (IOException e1) {
e1.printStackTrace();
} finally {
post.releaseConnection();
}
System.out.println("We have an access token: " + accessToken + "\n" + "Using instance " + instanceUrl + "\n\n");
HttpClient httpclient = new HttpClient();
GetMethod get = new GetMethod(instanceUrl + "/services/data/v28.0/query");
// set the token in the header
get.setRequestHeader("Authorization", "OAuth " + accessToken);
// set the SOQL as a query param
NameValuePair[] params = new NameValuePair[1];
params[0] = new NameValuePair("q",query);
get.setQueryString(params);
try {
httpclient.executeMethod(get);
if (get.getStatusCode() == HttpStatus.SC_OK) {
// Now lets use the standard java json classes to work with the results
JSONObject response = new JSONObject( new JSONTokener( new InputStreamReader(get.getResponseBodyAsStream())));
System.out.println("Query response: "+ response.toString(2));//.substring(0, 500));
System.out.println(response.getString("totalSize") + " record(s) returned\n\n");
JSONArray results = response.getJSONArray("records");
Account[] accounts = new Gson().fromJson(results.toString(), Account[].class);
return accounts;
}
}
catch (Exception e){
e.printStackTrace();
}finally {
get.releaseConnection();
}
}
}
对于 Java,最简单的方法是使用 Spring Social Salesforce: https : //github.com/iirekm/spring-social-salesforce
只需按照https://spring.io/guides/gs/accessing-facebook/ 上的 Facebook 教程进行操作,简而言之,将依赖项添加到 Spring Social Salesforce,并将代码“facebook”中的所有位置替换为“salesforce”。
