英文:
MailJet Not able to send from java email: ( 400 Bad Request )
问题
我尝试从我们的Java项目中发送电子邮件，但每次都出现400错误代码。所以我从Java控制台中获取相同的请求并在Postman中发送，使用相同的其他元素，然后从Postman中可以正常工作，我可以收到邮件，但从Java中仍然出现400错误的坏请求，当我打开Mailjet调试模式时，内容为空。
这是Java生成并从Postman注入的最终JSON：
{
"Messages": [
{
"Variables": {
"objet": " objet",
"body": " body "
},
"From": {
"Email": "no-reply@gmail.com"
},
"To": [
{
"Email": "send@gmail.com",
"Name": ""
}
],
"TemplateID": 111111,
"TemplateLanguage": true,
"Subject": "[[data:objet:\" anything\"]]"
}
]
}
Java代码：
/**
* 发送消息
* @return MailjetResponse
* @throws MailjetException
* @throws MailjetSocketTimeoutException
*/
public MailjetRequest sendEmailCore() {
return new MailjetRequest(Emailv31.resource)
.property(Emailv31.MESSAGES, new JSONArray()
.put(new JSONObject()
.put(Emailv31.Message.FROM, new JSONObject()
.put("Email", senderMail)
.put("Name", senderName))
.put(Emailv31.Message.TO, getRecipientsJson())
.put(Emailv31.Message.TEMPLATEID, TEMPLATE_ID)
.put(Emailv31.Message.TEMPLATELANGUAGE, true)
.put(Emailv31.Message.SUBJECT, "[[data:objet:\" anything\"]]")
.put(Emailv31.Message.VARIABLES, new JSONObject()
.put("objet", " objet")
.put("mailTitle", mailTitle)
.put("body", body))));
}
private JSONArray getRecipientsJson(){
JSONArray json = new JSONArray();
for (String recipient : recipients) {
json.put(new JSONObject()
.put("Email", recipient)
.put("Name", ""));
}
return json;
}
public MailjetResponse sendLoggedMail() throws Exception {
MailjetClient client = new MailjetClient(API_KEY_PUBLIC, API_KEY_PRIVATE, new ClientOptions("v3.1"));
MailjetRequest request = sendEmailCore();
MailjetResponse response = null;
try {
client.setDebug(MailjetClient.VERBOSE_DEBUG);
log.info(request.getBody());
response = client.post(request);
} catch (final MailjetException | MailjetSocketTimeoutException e) {
log.error("sendLoggedMail", e);
}
return response;
}

I try to send an email from our java project but every time I have a code error 400. So I take the same request printed in the java console and send it from Postman with the same other elements then it works from Postman and i receive the email but from java I have always the code error 400 bad request and when i turn on the Mailjet debug mode the content is null.
Here the final JSON made by Java and inject from Postman
{
"Messages": [
{
"Variables": {
"objet": " objet",
"body": " body "
},
"From": {
"Email": "no-reply@gmail.com"
},
"To": [
{
"Email": "send@gmail.com",
"Name": ""
}
],
"TemplateID": 111111,
"TemplateLanguage": true,
"Subject": "[[data:objet:\" anything\"]]"
}
]
}
The java code :
/**
* Send a message
* @return MailjetResponse
* @throws MailjetException
* @throws MailjetSocketTimeoutException
*/
public MailjetRequest sendEmailCore() {
return new MailjetRequest(Emailv31.resource)
.property(Emailv31.MESSAGES, new JSONArray()
.put(new JSONObject()
.put(Emailv31.Message.FROM, new JSONObject()
.put("Email", senderMail)
.put("Name", senderName))
.put(Emailv31.Message.TO, getRecipientsJson())
.put(Emailv31.Message.TEMPLATEID, TEMPLATE_ID)
.put(Emailv31.Message.TEMPLATELANGUAGE, true)
.put(Emailv31.Message.SUBJECT, "[[data:objet:\" anything\"]]")
.put(Emailv31.Message.VARIABLES, new JSONObject()
.put("objet", " objet")
.put("mailTitle", mailTitle)
.put("body", body))));
}
private JSONArray getRecipientsJson(){
JSONArray json = new JSONArray();
for (String recipient : recipients) {
json.put(new JSONObject()
.put("Email", recipient)
.put("Name", ""));
}
return json;
}
public MailjetResponse sendLoggedMail() throws Exception {
MailjetClient client = new MailjetClient(API_KEY_PUBLIC, API_KEY_PRIVATE, new ClientOptions("v3.1"));
MailjetRequest request = sendEmailCore();
MailjetResponse response = null;
try {
client.setDebug(MailjetClient.VERBOSE_DEBUG);
log.info(request.getBody());
response = client.post(request);
} catch (final MailjetException | MailjetSocketTimeoutException e) {
log.error("sendLoggedMail", e);
}
return response;
}
The MailJet log :
=== HTTP Request ===

Accept-Charset:UTF-8
Accept:application/json
user-agent:mailjet-apiv3-java/v4.5.0

默认连接超时的值在4.5.0版本中过小。
您可以尝试在客户端选项中设置值，如下所示：
new MailjetClient("public", "secret", new ClientOptions(8000));
或者直接使用更新的版本，其中已设置了默认超时值。
英文:
The default value for the connection timeout is too small in version 4.5.0
You can try to set value in client options like this:
new MailjetClient("public", "secret", new ClientOptions(8000));
or just use the newer version, where the default timeout value is set.

我在Java Mailjet客户端4.5.0上遇到了相同的问题。降级到v4.4.0时，这个错误就不会出现。
英文:
I have the same issue with Java Mailjet Client 4.5.0. Downgrading to v4.4.0 this error isn't there.
