The background,

In the current development project, I believe that we have encountered the need to send SMS. So we usually use third-party services, so HERE I have done API docking Tencent cloud, so I write down some experience for everyone. Some people may ask, the official website of the document is well written, you want to stay here, blah blah blah? I’m just using the situation as a docking point and point of view to tell you about the problems I’ve encountered. The official website says they know where and how things are configured, and we, as the docking person, have to look everywhere for documentation. So get started!

Ii. Preparation before docking

Then you need to open a Tencent cloud account. Cloud.tencent.com/ how to register for you to see, this is ok. After registering an account. We can search for SMS directly from the product and enter the SMS platform. You can also open the link below. Console.cloud.tencent.com/smsv2/manag…

After opening the SMS platform here, individuals will send 100 domestic, enterprises send 1000. Feeling optional.

When these are ready. The following start

Third, docking

We to docking is to open the document, right, API documentation here: cloud.tencent.com/document/pr…

They provide API and SDK document docking, or the same, I think SDK is reliable, why, the front docking U shield said, they have already written the code, you directly use the method, to avoid all to you avoid. then

We did what he told us to go to our pom.xml file and add the JAR package

<dependency> <groupId>com.tencentcloudapi</groupId> <artifactId>tencentcloud-sdk-java</artifactId> The < version > 3.1.270 < / version > <! --> </dependency> --> </dependency> --> </dependency> --> </dependency>Copy the code

And then, of course, let’s look at the following.

A code example of a short message occurring

Out. The println (SendSmsResponse. ToJsonString (res)); System.out.println(res.getrequestid ())); system.out.println (res.getrequestid ()); } catch (TencentCloudSDKException e) { e.printStackTrace(); }}}Copy the code

In fact, I feel that the official documentation here is really patient. It’s very complete. But the only point I need to add is here

[SMS Helper] */ String SenderId = "";Copy the code

At the beginning, I always thought that there would be this SenderID for international SMS, but the result is that I misunderstood, no matter international SMS or domestic do not need, this thing is not open at all, big customers will give you a. International text messages occur as long as in

+[Country or Region code][Mobile phone number] * An example is as follows: +8613711112222, where there is a + number in front, 86 is the country code, 13711112222 is the mobile phone number, A maximum of 200 mobile phone numbers */ String[] phoneNumberSet = {"+8621212313123", "+8612345678902", "+8612345678903"};Copy the code

Change the country code, and then you can send it if you buy the international package.

There is also a little bit, the website is a bit of a mess.

Domestic and international text messages touch version is not the same oh, if the word ID is created separately is not the same, for our docking special trouble. But there is a point, you can first set up the domestic SMS, and then it has a copy can be copied over. So I have the same ID.

Four,

These large domestic factories do play a particularly good lead role in documentation. For us developers, no customer service for technical docking, follow the documentation, step by step operation. You can implement it. In fact, I have also connected with Tencent cloud COS object file storage, which is also very interesting, I will sort it out in a couple of days. Why is Ali Cloud called OSS? Personally, IT may be that Tencent saw that Ali already has such a product with this name, and I want to build such a product. If the technical name is the same, it is not too LOW, so I will be COS.
