AFNetworking http基本身份验证会出现“您的API键没有正确格式化”错误。

Question

尝试使用邮差api，但遇到授权问题。

引用他们的网站：

认证 Postmates需要通过HTTP头进行身份验证。您的API键应该包含在用户名中。密码应保留为空。 实际使用的标题将是一个base64 64编码的字符串，如下所示： Basic Y2YyZjJkNmQtYTMxNC00NGE4LWI2MDAtNTA1M2MwYWYzMTY1Og==

我试过像这样使用AFNetworking

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

NSURLCredential *credential = [NSURLCredential credentialWithUser:@"(my postmates key)" password:@"" persistence:NSURLCredentialPersistenceNone];

NSMutableURLRequest *request = [manager.requestSerializer requestWithMethod:@"GET" URLString:@"https://api.postmates.com/v1/delivery_zones" parameters:nil];

AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
[operation setCredential:credential];
[operation setResponseSerializer:[AFJSONResponseSerializer alloc]];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"Success: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Failure: %@", error);
}];

[manager.operationQueue addOperation:operation];    

我得到的错误信息是

   Incorrect NSStringEncoding value 0x0000 detected. Assuming NSASCIIStringEncoding. Will stop this compatiblity mapping behavior in the near future.

 Success: {
        code = "invalid_authorization_header";
        kind = error;
        message = "Your API key was not formatted properly";
    }

Answer 1

与其创建凭据，不如尝试：

[request setValue:@"Basic Y2YyZjJkNmQtYTMxNC00NGE4LWI2MDAtNTA1M2MwYWYzMTY1Og==" forHTTPHeaderField:@"Authorization"];
