融云使用之获取Token值

先看一下官方给出的API签名规则

然后是签名请求参数准备,新建一个MSTool类，并导入头文件#import

代码如下：

#import "MSTool.h"
#import 

@implementation MSTool

+ (instancetype)sharedMSTool{
    static MSTool * tool = nil;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        tool = [[self alloc] init];
    });
    return tool;
}

//single_implementation(MSTool)

//获取随机数
-(NSString *)getRandomNonce
{
    NSInteger randomValue = [self getRandomNumber:100000 to:999999];
    return  [NSString stringWithFormat:@"%ld",randomValue];
}
//获取时间戳 从1970年
-(NSString *)getTimestamp
{
    NSDate *date = [NSDate date];
    NSTimeInterval times =  [date timeIntervalSince1970];
    return [NSString stringWithFormat:@"%.0f",times];
}

//获取从 from 到  to 的随机数
-(NSInteger)getRandomNumber:(NSInteger)from to:(NSInteger)to
{
    return (NSInteger)(from + (arc4random() % (to - from + 1)));
}

//sha1 加密
-(NSString *)sha1WithKey:(NSString *)key
{
    const char *cstr = [key cStringUsingEncoding:NSUTF8StringEncoding];
    NSData *data = [NSData dataWithBytes:cstr length:key.length];
    
    uint8_t digest[CC_SHA1_DIGEST_LENGTH];
    
    CC_SHA1(data.bytes, data.length, digest);
    
    NSMutableString *output = [NSMutableString stringWithCapacity:CC_SHA1_DIGEST_LENGTH * 2];
    
    for(int i=0; i

然后是在Appdelegate中设置

#pragma mark - 融云客服设置
- (void)getToken{
    
    NSString * url = @"https://api.cn.ronghub.com/user/getToken.json";
    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    manager.requestSerializer  = [AFHTTPRequestSerializer serializer];
    
    NSDictionary *dict = @{@"userId":请求用户唯一标识符@"name":用户名,@"portraiUri":图片的网址"};
    
    NSString *appkey = @"你在融云申请的App Key";
    NSString *nonce = [[MSTool sharedMSTool] getRandomNonce];
    NSString *timestamp = [[MSTool sharedMSTool] getTimestamp];
    NSString *signature = [[MSTool  sharedMSTool]getSignatureWithAppSecret:@"你在融云申请的AppSecret" nonce:nonce timestamp:timestamp];

    //设置请求头
    [manager.requestSerializer setValue:appkey forHTTPHeaderField:@"App-Key"];
    [manager.requestSerializer setValue:nonce forHTTPHeaderField:@"Nonce"];
    [manager.requestSerializer setValue:timestamp forHTTPHeaderField:@"Timestamp"];
    [manager.requestSerializer setValue:signature forHTTPHeaderField:@"Signature"];
    //调用POST方法
    [manager POST:url parameters:dict progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        NSLog(@"%@",responseObject);
      
        //客服设置
        [[RCIM sharedRCIM]initWithAppKey:@"你在融云申请的App Key"];
        [[RCIM sharedRCIM] connectWithToken:responseObject[@"token"] success:^(NSString *userId) {
            NSLog(@"LoginSuccess");
        } error:^(RCConnectErrorCode status) {
            NSLog(@"LoginFault");
        } tokenIncorrect:^{
            NSLog(@"Token_isEorro");
        }];
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        NSLog(@"%@",error);
    }];
}
