微信登录与分享
微信开发平台-移动应用微信登录开发指南
1、首先导入微信的SDK
2、导入需要的framework
3、添加URL Type
4、在plist文件里添加iOS9 URL Schemes 白名单
<key>LSApplicationQueriesSchemes</key>
<array>
<string>wechat</string>
<string>weixin</string>
<string>sinaweibohd</string>
<string>sinaweibo</string>
<string>sinaweibosso</string>
<string>weibosdk</string>
<string>weibosdk2.5</string>
<string>mqqapi</string>
<string>mqq</string>
<string>mqqOpensdkSSoLogin</string>
<string>mqqconnect</string>
<string>mqqopensdkdataline</string>
<string>mqqopensdkgrouptribeshare</string>
<string>mqqopensdkfriend</string>
<string>mqqopensdkapi</string>
<string>mqqopensdkapiV2</string>
<string>mqqopensdkapiV3</string>
<string>mqzoneopensdk</string>
<string>wtloginmqq</string>
<string>wtloginmqq2</string>
<string>mqqwpa</string>
<string>mqzone</string>
<string>mqzonev2</string>
<string>mqzoneshare</string>
<string>wtloginqzone</string>
<string>mqzonewx</string>
<string>mqzoneopensdkapiV2</string>
<string>mqzoneopensdkapi19</string>
<string>mqzoneopensdkapi</string>
<string>mqzoneopensdk</string>
<string>alipay</string>
<string>alipayshare</string>
</array>
5、向微信终端程序注册第三方应用，并在第三方应用实现从微信返回
在AppDelegate.m中引入”WXApi.h"头文件，然后写入如下:
#import "WXApi.h"
#import "WXApiObject.h"
@interface AppDelegate ()<WXApiDelegate> //添加代理
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[WXApi registerApp:@"WX_AppID" withDescription:@"weixin"];
return YES;
}
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options
{
[WXApi handleOpenURL:url delegate:self];
return YES;
}
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url
{
[WXApi handleOpenURL:url delegate:self];
return YES;
}
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
[WXApi handleOpenURL:url delegate:self];
return YES;
}
6、微信分享—>在控制器里面添加分享代码
#import "WXApiObject.h"
#import “WXApi.h"
//分享文字给好友
SendMessageToWXReq *req = [[SendMessageToWXReq alloc] init];
req.text = @"测试把信息分享到微信好友";
req.bText = YES;
req.scene = WXSceneSession;//会话(WXSceneSession)或者朋友圈(WXSceneTimeline)
[WXApi sendReq:req];
//分享图片给好友
WXMediaMessage *message = [WXMediaMessage message];
message.title = @"测试把图片分享到微信好友";
[message setThumbImage:[UIImage imageNamed:@"IconWX.png"]];
WXImageObject *imageObject = [[WXImageObject alloc] init];
NSString *filePath = [[NSBundle mainBundle] pathForResource:@"IconWX" ofType:@"png"];
imageObject.imageData = [NSData dataWithContentsOfFile:filePath];
message.mediaObject = imageObject;
SendMessageToWXReq *req = [[SendMessageToWXReq alloc] init];
req.bText = NO;
req.message = message;
req.scene = WXSceneSession;
[WXApi sendReq:req];
//分享网页给好友
WXMediaMessage *message = [WXMediaMessage message];
message.title = @"测试把web分享到微信好友";
[message setThumbImage:[UIImage imageNamed:@"IconWX.png"]];
WXWebpageObject *webObject = [WXWebpageObject object];
webObject.webpageUrl = @"http://www.baidu.com";
message.mediaObject = webObject;
SendMessageToWXReq *req = [[SendMessageToWXReq alloc] init];
req.bText = NO;
req.message = message;
req.scene = WXSceneSession;
[WXApi sendReq:req];
//分享文字到朋友圈
SendMessageToWXReq *req = [[SendMessageToWXReq alloc] init];
req.text = @"测试把信息分享到微信朋友圈";
req.bText = YES;
req.scene = WXSceneTimeline;//会话(WXSceneSession)或者朋友圈(WXSceneTimeline)
[WXApi sendReq:req];
//分享图片到朋友圈
WXMediaMessage *message = [WXMediaMessage message];
message.title = @"测试把图片分享到微信朋友圈";
[message setThumbImage:[UIImage imageNamed:@"IconWX.png"]];
WXImageObject *imageObject = [[WXImageObject alloc] init];
NSString *filePath = [[NSBundle mainBundle] pathForResource:@"IconWX" ofType:@"png"];
imageObject.imageData = [NSData dataWithContentsOfFile:filePath];
message.mediaObject = imageObject;
SendMessageToWXReq *req = [[SendMessageToWXReq alloc] init];
req.bText = NO;
req.message = message;
req.scene = WXSceneTimeline;
[WXApi sendReq:req];
//分享网页到朋友圈
WXMediaMessage *message = [WXMediaMessage message];
message.title = @"测试把web分享到微信朋友圈";
message.description = @"";
[message setThumbImage:[UIImage imageNamed:@"IconWX.png"]];
WXWebpageObject *webObject = [WXWebpageObject object];
webObject.webpageUrl = @"http://www.baidu.com";
message.mediaObject = webObject;
SendMessageToWXReq *req = [[SendMessageToWXReq alloc] init];
req.bText = NO;
req.message = message;
req.scene = WXSceneTimeline;
[WXApi sendReq:req];
6.1、分享App消息到微信，微信点击之后能够跳转到App
static NSString *kAPPContentTitle = @"App消息";
static NSString *kAPPContentDescription = @"这种消息只有App自己才能理解，由App指定打开方式";
static NSString *kAppContentExInfo = @"<xml>extend info</xml>";
static NSString *kAppContnetExURL = @"http://weixin.qq.com";
static NSString *kAppMessageExt = @"这是第三方带的测试字段";
static NSString *kAppMessageAction = @"<action>dotaliTest</action>";
//分享本App识别的信息（会从微信调整到本App）
Byte* pBuffer = (Byte *)malloc(1024*100);
memset(pBuffer, 0, 1024*100);
NSData* data = [NSData dataWithBytes:pBuffer length:1024*100];
free(pBuffer);
UIImage *thumbImage = [UIImage imageNamed:@"res2.jpg"];
WXAppExtendObject *ext = [WXAppExtendObject object];
ext.extInfo = kAppContentExInfo;
ext.url = kAppContnetExURL;
ext.fileData = data;
WXMediaMessage *message = [WXMediaMessage message];
message.title = kAPPContentTitle;
message.description = kAPPContentDescription;
message.mediaObject = ext;
message.messageExt = kAppMessageExt;
message.messageAction = kAppMessageAction;
message.mediaTagName = nil;
[message setThumbImage:thumbImage];
SendMessageToWXReq *req = [[SendMessageToWXReq alloc] init];
req.bText = NO;
req.scene = WXSceneSession;
req.message = message;
[WXApi sendReq:req];
7、微信登陆 —>在AppDelegate里面添加登陆成功的通知
#pragma mark - WXApiDelegate
- (void)onResp:(BaseResp *)resp {
if ([resp isKindOfClass:[SendAuthResp class]])
{
SendAuthResp *rep = (SendAuthResp *)resp;
if (rep.errCode == 0) {
[[NSNotificationCenter defaultCenter] postNotificationName:WXLoginSuccess object:@{@"code":rep.code}];
}
}
8、微信登陆 —>在控制器里面添加登陆代码
static NSString *kAuthScope = @"snsapi_userinfo";
static NSString *kAuthOpenID = @"这个我现在没使用";
static NSString *kAuthState = @"123";
//微信登陆
- (void)onClickBtn
{
SendAuthReq *req = [[SendAuthReq alloc] init];
req.scope = kAuthScope;
req.state = kAuthState;
req.openID = kAuthOpenID;
[WXApi sendReq:req];
}
9、微信登陆—>在控制器里面实现登陆成功之后的回调
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(WXLogin:) name:WXLoginSuccess object:nil];
//登陆成功之后获取token
- (void)WXLogin:(NSNotification *)notifi
{
AFHTTPRequestOperationManager *manage = [AFHTTPRequestOperationManager manager];
manage.responseSerializer = [AFHTTPResponseSerializer serializer];
[manage GET:@"https://api.weixin.qq.com/sns/oauth2/access_token" parameters:@{@"appid":WX_AppID, @"secret":WX_AppSecret, @"code":notifi.object[@"code"], @"grant_type":@"authorization_code"} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSDictionary *dict = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingAllowFragments error:nil];
/*"access_token" = "OezXcEiiBSKSxW0eoylIeBPKSgTfwua1QABCnleka9CqGYr9J4wP2NHLDEFTP0vqsiS4DFDyXNQmYSaM6dW1s8MrQi6NSC9dV6ZqqjazKWQv3kfeozrm-fbZTXU80vLaWYflw07nkDhmX3KJHsEVxQ";
"expires_in" = 7200;
openid = xxxxxxxxxxxxxxxxxxxxxxxxxx;
"refresh_token" = "OezXcEiiBSKSxW0eoylIeBPKSgTfwua1QABCnleka9CqGYr9J4wP2NHLDEFTP0vq6O1ZVOcyb8uL5dLrcuRaydRmY9BcYgJeOLqRjlLyp5HpBlYc2Ikja-RFm6ghGQ32r_iZfQfAQhtEqwk9ibf8vA";
scope = "snsapi_userinfo";
unionid = o4bo2vzI0vCvGTa11GBMkx0SbcwQ;*/
[[NSUserDefaults standardUserDefaults] setObject:dict forKey:WXSaveToken];
[self saveTokenAndRequireWXInfo];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"access_token error-->%@", error.localizedDescription);
}];
}
10、微信登陆—>在控制器里面通过token请求得到微信部分个人信息
- (void)saveTokenAndRequireWXInfo
{
NSDictionary *dict = [[NSUserDefaults standardUserDefaults] objectForKey:WXSaveToken];
AFHTTPRequestOperationManager *manage = [AFHTTPRequestOperationManager manager];
manage.responseSerializer = [AFHTTPResponseSerializer serializer];
[manage GET:@"https://api.weixin.qq.com/sns/userinfo" parameters:@{@"openid":dict[@"openid"], @"access_token":dict[@"access_token"]} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSDictionary *dict = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingAllowFragments error:nil];
// NSLog(@"%@",dict);
// {
// city = "xxx";
// country = xxx;
// headimgurl = “http://wx.qlogo.cn/mmopen/xxxxxxx/0”;
// language = "zh_CN";
// nickname = xxx;
// openid = xxxxxxxxxxxxxxxxxxx; //授权用户唯一标识
// privilege = (
// );
// province = "xxx";
// sex = 0;
// unionid = xxxxxxxxxxxxxxxxxx;
// }
[[NSUserDefaults standardUserDefaults] setObject:dict forKey:WXResponse_UserInfo];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"userinfo error-->%@", error.localizedDescription);
}]; }
