Question

我想使用 AFNetworking 访问 Twilio api。我试过很多方法，但没有成功。请帮助我，如果有人使用AFNetworking做了Tiwilo发布请求。

案例1：这是我的原生目标-c工作代码。

NSString *urlString = [NSString stringWithFormat:@"https://%@:%@@api.twilio.com/2010-04-01/Accounts/%@/SMS/Messages", kTwilioSID, kTwilioSecret, kTwilioSID];

NSURL *url                      = [NSURL URLWithString:urlString];
NSMutableURLRequest *request    = [[NSMutableURLRequest alloc] init];

[request setURL:url];
[request setHTTPMethod:@"POST"];

NSString *bodyString    = [NSString stringWithFormat:@"From=%@&To=%@&Body=%@", from, to, message];

NSData *data            = [bodyString dataUsingEncoding:NSUTF8StringEncoding];
[request setHTTPBody:data];

[NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {

    if (connectionError)
    {
        DLog(@"Error: %@", connectionError);

        completionBlock(connectionError, NO);
    }
    else
    {
        completionBlock(connectionError, YES);
    }
}];

案例2：使用AFNetorking：无效的代码：

代码：

    NSString *urlString = [NSString stringWithFormat:@"https://%@:%@@api.twilio.com/2010-04-01/Accounts/%@/SMS/Messages", kTwilioSID, kTwilioSecret, kTwilioSID];

NSDictionary *dict = @{
                       @"From" : from,
                       @"To" : to,
                       @"Body" : message
                       };


AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];

[manager POST:urlString parameters:dict success:^(AFHTTPRequestOperation *operation, id responseObject)
 {
     NSLog(@"Success: %@", responseObject);
 }
      failure:
 ^(AFHTTPRequestOperation *operation, NSError *error) {
     NSLog(@"Error: %@", error);
 }];

相关错误：

Error Domain=NSCocoaErrorDomain Code=3840 "The operation couldn’t be completed. (Cocoa error 3840.)" (JSON text did not start with array or object and option to allow fragments not set.) UserInfo=0x1775e660 {NSDebugDescription=JSON text did not start with array or object and option to allow fragments not set., NSUnderlyingError=0x175101b0 "Request failed: bad request (400)"}

案例3：使用AFNetorking：另一个也无效的代码：

代码：

 NSString *urlString = [NSString stringWithFormat:@"https://%@:%@@api.twilio.com/2010-04-01/Accounts/%@/SMS/Messages", kTwilioSID, kTwilioSecret, kTwilioSID];
NSURL *url                      = [NSURL URLWithString:urlString];
NSMutableURLRequest *request    = [[NSMutableURLRequest alloc] init];
[request setURL:url];
[request setHTTPMethod:@"POST"];

NSString *bodyString    = [NSString stringWithFormat:@"From=%@&To=%@&Body=%@", from, to, message];
NSData *data            = [bodyString dataUsingEncoding:NSUTF8StringEncoding];
[request setHTTPBody:data];

AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
operation.responseSerializer = [AFJSONResponseSerializer serializer];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"%@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"error: %@", error);
}];

[operation start];

相关错误：

 Error Domain=NSCocoaErrorDomain Code=3840 "The operation couldn’t be completed. (Cocoa error 3840.)" (JSON text did not start with array or object and option to allow fragments not set.) UserInfo=0x177a3e70 {NSDebugDescription=JSON text did not start with array or object and option to allow fragments not set.}

谢谢。

来自Twilio的Ricky在这里。首先是快速免责声明。直接从iOS应用程序向Twilio发出请求需要您在应用程序中嵌入Twilio帐户凭据，这很危险。我的建议是从您的应用程序发出请求的服务器端脚本发送SMS，以保证您的凭据安全。

话虽这么说，你的代码非常接近。默认情况下，Twilio's REST API returns XML。如果您想要解析默认情况下返回的响应，您可以更新版本2中的代码以使用AFXMLParserResponseSerializer：

operation.responseSerializer = [AFXMLParserResponseSerializer serializer];

如果您更愿意使用JSON，那么您需要更新发出POST请求的Twilio网址，并指出您喜欢JSON响应：

NSString *urlString = [NSString stringWithFormat:@"https://%@:%@@api.twilio.com/2010-04-01/Accounts/%@/SMS/Messages.json", kTwilioSID, kTwilioSecret, kTwilioSID];

希望有所帮助。
